12' (3.7m)

Time Delay

The time delay can be selected by the user during set up. It can be adjusted from 15 seconds up to 30 minutes. For additional information on how to adjust it, please read the SENSOR ADJUSTMENT & PROGRAMMING section of this installation manual.

Light Level

When the sensor is set for occupancy sensor Mode 2 (Auto-ON/OFF) the light level feature prevents the sensor from automatically turning the lights ON if there is already enough light in the area. To adjust the light level, please read the SENSOR ADJUSTMENT & PROGRAMMING section of this installation manual.

Coverage Area

The RS-250 has a maximum range of 180 degrees and a coverage area of 600 sq. feet (56 sq. meters). The sensor must have a clear and unobstructed view of the coverage area. Objects blocking the sensor’s lens may prevent detection thereby causing the light to turn OFF even though someone is in the area.

Windows, glass doors, and other transparent barriers will obstruct

the sensor’s view and prevent detection.

INSTALLATION & WIRING

WARNING

Disconnect power to the wall switch box by turning OFF the circuit breaker or removing the fuse for the circuit before

installing the RS-250, replacing lamps, or doing any electrical work.

1.Prepare the switch box.

After the power is turned OFF at the circuit breaker box, remove the existing wall plate and mounting screws. Pull the old switch out from the wall box.

2.Identify the type of circuit.

In a Single Pole Circuit (see Fig. 2), two single wires connect to two screws on the existing switch. A ground wire may also be present and connected to a ground terminal on the old switch. A neutral wire should also be present in the wall box.

Wiring

CAUTION - FOR YOUR SAFETY: Connecting a proper ground to the sensor provides protection against electrical shock in the event of certain fault conditions. If a proper ground is not available, consult with a qualified electrician before continuing installation.

Only connect the RS-250 to a Single Pole Circuit. The RS-250 is not suitable for 3-way switching. If the existing wiring does not match the description for a Single Pole Circuit, you should consult with a qualified electrician.

3.Prepare the Wires.

Tag the wires connected to the existing switch, so that they can be identified later. Disconnect the wires. Make sure the insulation is stripped off the wires to expose their copper cores to the length indicated by the “Strip Gage,” (in Fig. 3) (approx. 1/2 inch).
