American Standard Selectronic Cast Touchless Faucet, Battery-Powered, 0.5 gpm/1.9 Lpm - AMS-6055105

Single-hole installation is what the Selectronic cast spout is built for. If your deck has 4 inch or 8 inch centers instead, an optional deck plate covers those hole spacings, so a three-hole deck can still take the faucet with the right plate ordered alongside it.

There is one inlet, and it takes either cold or tempered water. That means no mixing happens at the faucet itself. If you want warm water at the spout, the temperature has to be set upstream, typically by a thermostatic mixing valve feeding the supply. Buyers replacing a two-handle manual faucet should plan for that, because the existing hot and cold stops cannot both land on this single inlet.

No electrical rough-in is needed. It runs on a CR-P2 lithium battery that ships with the faucet, so it can go into an existing deck without pulling a circuit or adding a transformer under the counter. That is the usual reason this version gets specified over a hardwired sensor faucet in a retrofit.

Flow is 0.5 gpm (1.9 Lpm) through a pressure-compensating multi-laminar spray. The pressure-compensating part is what matters on a multi-story building or a busy restroom bank: the outlet holds the rated flow rather than surging on the high-pressure floors and dribbling on the low ones. The 0.5 gpm rate is the metering-style flow used in public lavatory applications, not a kitchen production flow.

A safety timer shuts the water off automatically after 55 seconds, so a sensor held open by a rag, a bag on the deck, or a smeared lens cannot flood a restroom. There is also an auto purge that runs the water periodically to clear stagnant water out of the line, which is the feature facility people ask about for low-traffic restrooms and stagnation management.

The sensor is programmable using an optional remote control, which is bought separately from the faucet. Out of the box it works on its factory settings, so the remote is only needed where you are fighting reflections off a bright deck, a mirror, or a wall close behind the spout, or where you want to standardize settings across a run of fixtures.

Touchless makes sense where hand contact is the problem, high-traffic public restrooms, healthcare, food service, since nobody touches the fixture to turn it on. The battery version specifically fits retrofits: no power at the sink, no under-counter transformer, no electrician on the job. The trade-off is a battery to replace on a schedule and a sensor lens that has to stay clean. A manual faucet is the simpler choice for a low-traffic, single-tenant space where nobody is going to maintain a sensor.

Both the spout and the spray outlet are vandal-resistant, the spout being a cast body rather than a thin tube. That is the reason it turns up in schools, transit, and public-facing restrooms where a standard aerator gets unscrewed or snapped off. It is a single-hole deck-mount fixture, so it does not address wall-mount or gooseneck prep openings.

It is ordered as model 6055105.002, and chrome is the finish that number carries. For a facility standardizing across restrooms, that single part number covers the whole fixture including the battery, with the deck plate and the programming remote as separate line items if you need them.
