What are the main features and benefits of the S-9010 and S-9020?
We developed this product line in order to provide the highest level of vandal protection, while simultaneously providing for the simplest and quickest installation and service of any sensor faucet on the market. Speakman's extensive experience in developing high quality sensor systems has culminated in making this the most durable and reliable sensor product on the market.
The key design feature of this product line is that all the components of the faucet are housed within the faucet body, and are easily accessible with the faucet cover removed. In other words, the entire faucet system is housed above counter.
We further incorporated many features and benefits as standard in each product. Every S-9010 or S-9020 comes with mechanical mixing valves, dual hot and cold filters and check valves, both 0.5 GPM and 2.2 GPM aerators, and an inlet cap for tempered water installations.
-
What are the key vandal protection features of the S-9010 and S-9020 design?
The most critical vandal protection feature is that all the sensor components are housed within the faucet body and are fully protected from any user or visitor to the facility. The only access to these components is by removing the faucet cover.
The S-9010 battery operated unit has no components or wires under the counter!
The S-9020 AC powered unit also has no components under the counter.
The S-9020 does have a transformer wire that runs under the counter from the faucet to the transformer. The transformer wire for the S-9020 has been lengthened to allow for a plug connection behind the wall. The section of wire exposed under the counter is protected by a stainless steel wire jacket. Other important vandal protection features are:
The faucet cover and chassis are both metal die-castings and are constructed for maximum strength and durability.
Dual mounting posts on 4" center holes prevent the faucet from being rotated on the counter.
Fully recessed aerator housing that protects the aerator and does not allow a hold point for someone to grab and pull.
The sensor lens is flush with the face of the faucet chassis to help prevent burning and picking of the lens.
The Speakman name is not stamped on the lens. This reduces the visibility of the lens, which in turn pre-empts the idea of scraping the lens to remove the lettering.
The cover housing screws are moved out of the general line of sight, which makes mischief less enticing.
Tamper resistant screws are also available
-
What are the target markets for S-9010 and S-9020 Sensorflo faucets?
The primary target markets for this product line are schools and universities. Secondarily, other facilities with high traffic and/or potential vandalism are ideal for these products.
-
Do the S-9010 and S-9020 models use the same sensor components as the Speakman lavatory and gooseneck sensor product lines?
Yes. We have used the same sensor and solenoid systems that have proven so reliable in our current lavatory and gooseneck sensor product lines. The sensor is actually the exact same sensor unit that is currently used in our S-8700 and S-8800 lavatory product line, with the exception that the Speakman name is not on the lens.
The internal workings of the solenoid are exactly the same as those in our current products. The only change is that the solenoid housing has been adjusted to fit this design. The solenoid repair kit that works for our current line will also work with this new S-9010 and S-9020 product line.
-
Is the sensor on the S-9010 and S-9020 Sensorflo faucet programmable or adjustable?
No. We strongly believe that any sensor faucet should work as intended without the need for adjustment. This makes the installation, operation and maintenance of the faucet much simpler and reduces the opportunity for unintended operating problems.
Importantly, a simple non-adjustable system allows us to simplify the electronics design, which in turn minimizes potential problems. The simplicity of our electronics design provides us with a highly reliable and stable sensor system.
-
How do the mixing valves work and how do we adjust the temperature on the S-9010 and S-9020 Sensorflo faucets?
The dual mixing valves act as flow regulators for both the incoming hot and cold water supply. The mixers are spindles that, when screwed in, will gradually reduce the flow of water. Adjusting the flow of water allows the facility to regulate the outlet temperature of the water.
-
Can I use a thermostatic mixing valve with the S-9010 and S-9020 Sensorflo faucets?
No problem. Speakman offers a TMV as an option. In this case, the TMV would be mounted under the counter and the outlet of the TMV would be connected to either the hot or cold inlet of the faucet (either side is acceptable). A cap is provided with each faucet to block the faucet inlet that is not used.
-
Are check valves included in the S-9010 and S-9020 Sensorflo faucet?
Yes. Check valves are included in each faucet. An important feature of this design is that the check valves are located downstream of the faucet filters. This will keep the checks clean of debris and eliminate a potential field maintenance problem.
-
Why are there two filters on the S-9010 and S-9020 Sensorflo faucets?
Two filters are used to keep both the hot and cold water inlets clean. The filters keep both the hot and cold check valves, solenoid and aerator clean from dirt and debris. In addition, having dual filters extends the time between filter cleanings in dirty water locations, further reducing maintenance and servicing time.
-
Why do you provide two flow controls with each S-9010 and S-9020 faucet?
The 0.5 GPM aerator comes installed in each faucet and a 2.2 GPM aerator is provided in a bag group with each faucet. This gives each facility more flexibility to decide which outlet is best for them. It further eliminates another option for the Speakman factory to handle, which increases the speed of shipments. Ultimately, this provides better flexibility and service to the customer.
-
What will be the main service issues for the S-9010 and S-9020 Sensorflo faucets?
The faucet system is designed for a minimum amount of maintenance. Again, when needed, all maintenance is performed above the counter. The main service issues will be:
Changing batteries of the S-9010.
Cleaning the filters depending on the local water quality conditions.
Maintaining the solenoid is recommended about every five years, depending on site use conditions. This product line uses the same RPG76-0039 solenoid repair kit as the other current Speakman Sensorflo models.
-
What types of batteries are used in the S-9010 Sensorflo faucet, how long will they last and where can I buy replacement batteries?
Speakman uses two 3-volt lithium batteries, Duracell size 123. Battery life is very dependent on site volume. In our experience, we typically see over one year of battery life in moderate to heavy traffic areas and up to two years or more in lighter traffic areas.
Replacement batteries can be purchased at most stores that carry batteries. Speakman also can supply replacement batteries. We have included volume pricing for batteries in our repair parts price list, to provide more attractive pricing and lower service costs to our customers.
-
Is it difficult to change the batteries in the S-9010 Sensorflo faucets?
It is very easy to replace the batteries. Remove the two screws from the black faucet chassis and lift off the cover. The battery housing is located at the top of the faucet. Unscrew the battery cap cover and replace the batteries. The battery cap and batteries are accessible without the need to remove the sensor/battery pack from its bracket within the faucet.
-
Can the customer service the solenoid valve on the S-9010 and S-9020 Sensorflo faucets?
Yes. The customer can service the solenoid using Speakman repair kit RPG76-0039.
-
If I use the S-9020 AC system, how do we vandal protect the transformer wire?
The transformer wire has been extended so that the plug connection between the faucet and transformer can be made behind the wall. The section of the transformer wire that is exposed under the counter is protected by a stainless steel wire jacket to prevent it from being cut or sliced. A wire clip is also provided to secure the wire jacket inside the wall.
If the transformer is located within the walls of the facility, the transformer and wires can be further protected with a covered junction box and conduit or wire covers.
-
What does the contractor need to do to install the S-9010 and S-9020 Sensorflo faucets?
Very little time and effort is needed to install these faucets. The faucets are shipped fully assembled. Only the batteries need to be installed on the S-9010.
For the S-9010, the installer would remove the faucet cover and battery cap, install the two batteries, replace the battery cap and cover, tighten the faucet to the counter and connect the water supplies.
For the S-9020, the faucet is fully assembled and ready for counter mounting and supply connections. Simply plug in the transformer to an outlet and plug the faucet wire to the transformer wire to charge the unit. Secure the wire with the wire jacket clip to the wall.
-
Why doesn't Speakman offer an S-9010 or S-9020 Sensorflo faucet with an external user temperature control?
Speakman does offer a user temperature control on our lavatory and gooseneck product lines. For the S-9010 and S-9020, the focus market and application is for high potential vandal areas. For these sites, facilities need the ability to pre set the temperature while also preventing the user from adjusting or tampering with the temperature control mechanism. The S-9010 and S-9020 provide both the facility adjustment necessary, while simultaneously providing maximum protection to the mixer by securing it within the faucet body.
-
Why isn't Speakman marked on the front of the S-9010 or S-9020 Sensorflo faucet?
We have elected to remove the Speakman name from the sensor lens on the S-9010 and S-9020 to prevent the potential for the lens to become a target area for vandalism. By removing the white lettering found on our current lavatory and gooseneck models, the black lens blends in with the black chassis (belly plate) and becomes much less noticeable. This makes the lens much less conspicuous thereby reducing the potential it will be seen as a vandal opportunity.
-
Will Speakman discontinue any other sensor faucets with the introduction of this S-9010 and S-9020 product line?
No. All current Speakman models remain active and available for sale.
-
How does the price of the S-9010 and S-9020 compare to the Speakman equivalent models of the lavatory sensors S-8711 and S-8811?
The list price for the S-9010 is the same as the S-8711. The list price of the S-9020 is the same as S-8811.
-
The S-8800 looks identical to the existing S-8700 faucet, what is the difference?
They both utilize 99% of the same components and are based on the same infrared and solenoid valve technology. The only difference is the power source. The S-8800 series uses an AC adapter that replaces the lithium batteries and module cap but shares the rest of its components with the S-8700 series. The goosenecks S-8100 (battery) and S-8200 (electric) are based on the same technology, and thus appear to be identical at first glance.
-
Is there a quick way to identify a battery unit from an electric powered unit?
All battery powered units have only one wire below the deck that connects to the solenoid. The electric powered versions have the solenoid connection (yellow) and an electrical wire (black).
-
What are the advantages of manual override on a sensor faucet?
Manual override provides all the benefits of a sensor faucet, combined with the ability to activate it just like a standard manual faucet. This is an especially popular option in healthcare settings as it provides maximum hygienics and maximum ease of operation in heavy use environments. It is also an excellent choice in locker rooms as people prefer to perform certain grooming activities like shaving with a constant flow of water.
-
Does the Sensorflo gooseneck line (S-8100 and S-8200 series) have any unique advantages?
Since healthcare facilities installing sensor faucets are doing so for the hygienic benefits, Speakman offers the option of a plain end spout with a laminar flow control in the base of the spout. This configuration eliminates the possibility of build-up of bacteria within the aerator. Plain end spouts are required by the plumbing code for healthcare facilities in many regions of the United States. The gooseneck spouts may also be removed and replaced from above the counter.
-
How can I adjust the sensor?
Simplicity of installation and maintenance was a key design objective. By setting the focal length to the proper distance based on the type of spout, along with setting the proper angles to prevent false activation from reflection, we eliminated the need for adjustment. By eliminating the need to adjust the sensor we simplified our electronics design allowing for maximum stability and reliability.
-
Why are Speakman's electronic faucets easier to install than the competitions'?
All of the circuit boards, the sensor and the batteries on the battery powered units are located above the counter in the faucet housing. Additionally, the majority of the faucet is preassembled. The only electronic item below the counter is the solenoid valve, which is threaded on to the base of the faucet. Also, the solenoid valve rotates 360° for maximum flexibility. No parts ever require wall mounting, saving considerable contractor installation time. With fewer parts below counter, the amount of time spent by the installer in cramped quarters under the sink is minimized. Another simplification on the installation process is the elimination of the need to adjust the sensor.
We also offer the option of stainless steel flexible hoses to make installation even easier. Our under-counter mixers connect directly to the solenoid for added convenience.
-
Why are the Speakman Sensorflo faucets simpler to maintain than the competitions'?
The above counter battery feature allows the maintenance crew to replace batteries without ever needing to get under the sink. Additionally, there are four spout options which may be installed from above counter with removal of the cover and two mounting screws. Competitors' units that feature electronic components secured to the wall are often difficult to maintain as these components are not always within easy reach when maintenance is required.
-
What are the most common maintenance issues with Speakman's electronic faucets?
Units that are battery powered will need new batteries every one to two years depending on usage. This is an all above counter task with Speakman electronic faucets. The other most common task is cleaning of the solenoid filter. While the solenoid is located below the counter, the filter is strategically placed on the under-side of the unit, so that it can be easily removed, rinsed of debris and replaced.
-
How do I know it's time to replace the batteries on my Sensorflo faucet ?
Before the unit becomes inoperable, there is a red low battery warning light inside the sensor window programmed to light up when batteries reach about 10% of their remaining operating life. Under normal conditions, this light provides two - three weeks notice of the need to replace the batteries.
-
What happens when the battery fails in a Sensorflo faucet?
The faucet will shut-down in the off position and will not operate until new batteries are installed.
-
What type of batteries do the battery powered faucets use?
Speakman's battery powered electronic faucets use (2) 3 volt lithium batteries. Lithium batteries have a longer shelf life than do alkaline batteries. This is helpful in lower use installations like doctor offices or individual patient rooms. These Lithium batteries have double the shelf life of alkaline batteries.
-
Aren't lithium batteries more expensive?
Yes, they are slightly more expensive than alkaline batteries, but the added life and reduced cost of maintenance personnel time make up for the minor added cost.
-
Must the lithium batteries be purchased from Speakman Company?
While Speakman does offer them as a repair kit, they are of a standard size commonly used in cameras and other electronic devices. Speakman does, however, recommend use of batteries from one of the leading brands, as we have encountered problems with generic or store brand batteries. All Speakman battery powered units are supplied with Duracell® batteries.
Speakman now offers volume pricing on larger quantities of batteries which can make them much less expensive than retail prices.
-
If we elect to use AC/electric powered units (S-8200 / S-8800) what are our power connection options?
All AC/electric series faucets come standard with a two prong AC transformer. This transformer is compatible with standard 120 volt AC electrical outlets and includes a 10' cord with waterproof male/female connections.
You may order the units less transformer (LT) and purchase one of our multi-unit transformers. The first alternative is a SU, which like the standard AC transformer plugs into a standard 120 volt AC electrical outlet, but can power up to three (3) faucets. The other alternative is a hardwired transformer which can power up to six (6) faucets, this is our SUH model. Both the SU and SUH models wire the units in series, via wires supplied with male/female water-proof connectors.
-
What are the mechanical mixing options on Speakman sensor faucet?
The first option is a unit with an under-counter mixer. This is a mechanical mixer that simply sets the ratio of hot and cold water by restricting the flow of hot water. Water pressure changes and variances of temperature of water in the hot water lines can affect the temperature of the water delivered.
Often the alternative selected in healthcare environments or in executive type offices is a unit with an above-counter mixer. This allows the user to adjust the temperature to their individual needs. Speakman's above-counter mixers also incorporate a temperature limit stop (TLS). The TLS mechanically limits the ability to open the mixer beyond a selected point. It should be noted that the TLS prevents scalding, but with a significant drop in cold water pressure scalding could occur, just like with a standard mechanical faucet.
-
How can I prevent scalding when using a Speakman sensor faucet?
Use of an under-counter thermostatic mixing valve ("TMV") is the best alternative to prevent scalding. At installation, the TMV is preset for a uniform temperature which is regulated by a wax element. Some local codes now require a TMV in specific conditions. Please check your local codes to see if a TMV is required.
TMV can be used like a standard under counter mixer to deliver a preset temperature of water or it may be used with an above-counter mixer. By regulating the maximum temperature of water allowed into the above-counter mixing valve via a TMV, user convenience is maximized and scalding is prevented.
-
How is Speakman so confident in the reliability of its electronic products?
Our products have undergone extensive third party testing to verify the safety and reliability of the electronics. Speakman utilized similar testing for its first battery powered sensor faucet (S-8700 series), which has an excellent track record for reliability. The S-8100, S-8200, S-8700 and S-8800 series faucets are all based on the same technology.
-
Do the S-8100 & S-8700 product lines comply with NSF-61?
The product has passed compliance testing for lead leaching as required by NSF-61. It is not a certified product as sensor type faucets are excluded from NSF-61.
-
The sensors in the Speakman electronic faucets look very similar, are they the same?
While the sensors are based on the same electronics design, and from first review look very similar, they are programmed differently. The S-8700/S-8800 series sensors have a shorter focal distance and quicker shut off (less than 1/2 second) designed specifically for the dimensions of the low spout lavatory units. The S-8100/S-8200 series focal distance is considerably longer to accommodate the gooseneck and it will allow the water to run for 2 seconds once a user removes their hands.
The S-8700 and S-8800 have a 60 second timeout feature on for increased vandal resistance. The timeout feature is extended to 120 seconds of continuous use on the S-8100 and S-8200 series faucets. This extended timeout is because healthcare practitioners on average wash their hands much more thoroughly than do people in restrooms.
-
What happens when the sensor's time-out feature is triggered?
The faucet will automatically stop running. Once the user removes his/her hands, the sensor will automatically reset immediately and become operational again. This also prevents potential flooding disasters should an object accidentally or purposely by a vandal be placed in the line of the sensor for an extended period of time.
-
The belly plate on the low spout lavatory electronic faucets looks similar to other competitors', is this plastic like those?
No, it is not plastic. It a metal casting covered with a powder coated synthetic finish for protection from pitting caused by harsh chemicals often employed in cleaning public restrooms.
-
Are any other finishes other than polished chrome available for the Sensorflo faucets?
For the S-8700 and S-8800 series we have a PVD finish with a polished chrome appearance that is excellent for upscale hotel lobbies and executive washrooms. The gooseneck series only is available in polished chrome.
-

-
How does the product numbering system for sensor faucets work?
First, any product in the S-8000 series is an electronic sensor product. The basic format for each of these product series are:
The second number in the part number (S-8XYZ):
Where X is 1 - 1 means it is a battery powered gooseneck faucet
Where X is 2 - 2 means it is an AC powered gooseneck faucet
Where X is 7 - 7 means it is a battery powered low spout lavatory faucet
Where X is 8 - 8 means it is an AC powered low spout lavatory faucet
The third number in the part number (S-8XYZ):
Where Y is 0 - 0 means there is no deck plate
Where Y is 1 - 1 means there is a four inch deck plate
Where Y is 2 - 2 means there is an eight inch deck plate
The fourth number in the part number (S-8XYZ):
Where Z is 0 - 0 means there is no mixing valve
Where Z is 1 - 1 means there is an under-counter mixing valve
Where Z is 2 - 2 means there is an above-counter mixing valve
Where Z is 9 - 9 means there is an above-counter mixing valve & manual override valve
For example model S-8111 would be a battery operated gooseneck faucet with a four inch (4") deck plate and under-counter mixer. Other options are available and noted as suffixes.
