American Standard NextGen Selectronic Touchless Faucet, Battery-Powered, 0.35 gpm/1.3 Lpm - AMS-7755103

No under-deck control box. The NextGen Selectronic is fully self-contained, with the electronics and the CR-P2 lithium battery housed in the faucet body itself. That keeps the cabinet clear and means the serviceable parts sit above the deck where you can reach them without crawling under a vanity.

The faucet itself is a single-hole fixture, but American Standard offers an optional deck plate that covers 4-inch (102 mm) or 8-inch (203 mm) centers. If you are replacing a centerset or widespread faucet and the deck already has three holes, order the deck plate with it or you will be looking at two open holes.

Single inlet only, fed with either cold or tempered water. There is no mixing valve and no handle on the faucet. If the application needs warm water at the spout, you supply it upstream with a thermostatic mixing valve or a tempered supply line. Buyers replacing a two-handle faucet should plan for that change in the rough-in.

A safety timer shuts the water off automatically after 55 seconds. So a bag on the deck, a stuck sensor, or a kid holding a hand under the spout will not flood a lavatory or run the meter overnight. There is also an auto purge cycle that periodically flushes stagnant water from the faucet, which is what facilities want in buildings with low occupancy or seasonal shutdowns.

For a retrofit with no power at the lavatory, battery is the straightforward path, and the 5-year CR-P2 in this faucet means a maintenance tech is not changing AAs every season. Hardwired makes more sense on new construction with high traffic, where you are already running conduit and want to eliminate battery changes entirely. The tradeoff with this model is that it takes a single supply, so tempering has to happen upstream either way.

0.35 gpm (1.3 Lpm) through a pressure-compensating multi-laminar spray, so the flow holds steady as building pressure fluctuates. That is a low-flow rate aimed at high-traffic public restrooms where water use per hand wash is the number being watched. If your facility expects a 0.5 gpm or 1.0 gpm aerator, this is a lower rate than that.

Yes, the 0.35 gpm multi-laminar spray outlet is vandal-resistant, which matters in schools, transit facilities, and any restroom where a standard screw-off aerator walks off. Combined with touchless operation and no exposed handle, there is very little on the fixture for someone to remove.

Top-mount installation. The faucet drops in and secures from above the deck, which is the difference between a 15-minute swap and pulling out everything under a cabinet. Service is the same story, since the accessible parts including the battery are reached from the top.

Two finishes: polished chrome, ordered as 7755103.002, and brushed nickel, ordered as 7755103.295. If you are standardizing a floor of restrooms, quote by that suffix so the whole run matches.
