Electronic Lavatory Faucet

Model LK737AC

Operation

A continuous invisible beam of light is emitted from the sensor

located at the base of the lavatory faucet.

As the user’s hand enters the beam’s effective range, the beam is

reflected back into the sensor receiver and activates the solenoid

valve allowing water to flow from the faucet. Water will flow until the

hands are removed or until the faucet reaches its automatic time out

limit setting.

When the hands are moved away from the sensor, the loss of reflect-

ed light initiates an electrical signal that deactivates the solenoid

valve, shutting off the water flow. The circuit then automatically

resets and is ready for the next user.
