American Standard Serin Touchless Faucet, Base Model, 0.35 gpm/1.3 Lpm - AMS-206B116

The Serin touchless faucet base model is the spout only. It runs on a modular platform: you pick the faucet, then a control box (solenoid or thermostatic mixing valve), then a power supply from five options, and each of those components is sold separately. Ordering the faucet by itself will not give you a working fixture at the sink. Plan the control box and power choice at the same time you pick the finish.

Single hole is the native install. It will work on a multi-hole deck if you add a 4-inch or 8-inch deck plate, which is a separate order. Match the plate to the hole spacing already drilled in the sink or counter, 4-inch centerset or 8-inch widespread.

0.35 gpm (1.3 Lpm) is a low-flow handwashing rate, which is what the Serin touchless is built around, and it is rated commercial. That flow is fine for handwashing in a restroom or public washroom. It is not a rate you want feeding a utility sink, a mop sink, or anywhere someone needs to fill a bucket.

The sensor sits in the tip of the spout, not in a separate eye on the deck or in a wall box. Hand motion at the outlet turns the water on and off. That location matters for two reasons: nothing extra gets drilled into the deck, and the detection zone is right where the user's hands already are, under the spout.

Auto purge is built in. The faucet can be programmed to open at a set interval after the last use and clear the faucet body and supply lines of stagnant water. For a school over summer break, a hotel floor out of service, or a vacant tenant suite, that is the feature that keeps water moving without sending someone around to run every tap.

A safety timer shuts the water off after 55 seconds of continuous run. If a towel, a bag, or a piece of debris parks in front of the sensor, the faucet stops rather than running until someone notices. That is the answer to the usual objection to sensor faucets in high-traffic public restrooms.

Both are offered, and the choice comes down to whether the faucet needs tempered water. A solenoid control box just opens and closes flow, so it takes whatever temperature the supply delivers. The thermostatic mixing valve box blends hot and cold at the fixture, which is what you specify when the opening is a public handwashing lavatory in healthcare, education, or hospitality and scald protection is on the drawing. The box is a separate line item either way.

Programming is done through an optional remote control, which is a separate item. That is how you set the purge interval and the sensor behavior. If you are standardizing a floor or a whole building on these, one remote covers the fleet, so you do not need one per faucet.

Two finishes: chrome, model 206B116.002, and brushed nickel, model 206B116.295. Both are the same base-model spout at 0.35 gpm. If you are matching existing Serin trim across a facility, order by that full model number rather than by finish name.

The faucet measures 17.126 x 10.394 x 4.252 inches and weighs 3.219 pounds. Check the height figure against any window sill, mirror, or backsplash cabinet directly behind the sink before you commit, and check the depth against how far the bowl sits back from the wall.
