American Standard NextGen Selectronic Touchless Faucet, Battery-Powered With SmarTherm Safety Shut-Off + ADM, 0.5 gpm/1.9 Lpm - AMS-7755305

No under-deck control box. The NextGen Selectronic is a self-contained battery faucet, with the CR-P2 lithium battery installed in the faucet body itself and the electronics integrated above deck. That matters on shallow cabinets, on ADA knee-space lavatories where the space under the bowl has to stay clear, and on retrofits where there is nowhere to mount a box. Everything serviceable is reachable without crawling under the sink.

It plumbs with dual inlets, hot and cold, and mixes above deck. Temperature is set with a removable handle at the faucet, so a facility can set the blend and pull the handle to lock users out of it. That is different from a cold-only sensor faucet, which takes a single supply, so budget for both stops at the rough-in.

SmarTherm safety shut-off is built in, and it is ASSE 1070 certified. If the cold supply fails, the faucet shuts down rather than delivering hot water at the spout. For schools, healthcare, and long term care where ASSE 1070 is written into the spec, that certification is the line item the plans reviewer is looking for.

The faucet itself is a single-hole top-mount unit, and an optional deck plate covers either 4 inch (102 mm) or 8 inch (203 mm) centers. So a three-hole deck is workable, but the deck plate is a separate order, not something that arrives in the faucet carton. Order it with the faucet if you are replacing a centerset or widespread on an existing lavatory.

No electrical rough-in. The NextGen Selectronic runs on a CR-P2 lithium battery rated 5 years and installed in the faucet, so there is no transformer, no junction box, and no electrician on the job. For a property manager converting existing manual lavatories to touchless one restroom at a time, that removes the largest cost in the conversion.

0.5 gpm (1.9 Lpm), through a pressure-compensating multi-laminar spray, so the flow holds steady as building pressure swings across floors. The aerator is vandal-resistant, which is the reason this spec shows up in public restrooms. If your fixture count was calculated on a 1.5 or 2.2 gpm faucet, this will noticeably change fill times at the bowl.

Yes, it installs from the top. On a stone or solid surface deck with a tight bowl behind it, that is the difference between a 20 minute swap and pulling the lavatory. Service access follows the same logic, since the battery and serviceable parts are reached from above rather than through the cabinet.

Auto Purge periodically runs the faucet to clear stagnant water from the line. That is the feature to point at for seasonal buildings, unoccupied floors, and healthcare water management plans where line stagnation is the concern behind the question.

Only if you leave the handle on. Mixing happens above deck through a removable handle, so maintenance can set the temperature and take the handle off, which fixes the blend for everyone using the fixture. Leave it in place and it behaves like a normal single-handle faucet with hands-free flow.

Two: polished chrome, model 7755305.002, and brushed nickel, model 7755305.295. Chrome is the usual choice where the rest of the restroom trim is already chrome and the fleet has to match; brushed nickel hides water spotting better in hospitality and multi-family. Order by the full suffix, since the base number alone does not identify the finish.
