Important Notes
Please read before installing.
1. Neutral wire required.
2. Device will not function if Black wires (Circuit 1/
Line 1) are not wired.
3. This product is rated to control 6 A per circuit.
Circuits may NOT be wired in parallel to control
loads greater than 6 A.
4. When power is applied, the sensor switch can be
manually turned on or off after the first
10 seconds and will automatically control the
load after 2 minutes.
5. CAUTION: Risk of Electric Shock — More than
one disconnect switch may be required to de-
energize the equipment before installing the unit,
rewiring, or replacing bulbs.
6. The sensor switch requires an unobstructed view
of the room and line-of-sight to detect motion.
7. Hot objects or moving air currents can affect the
performance of the sensor switch and may cause
the sensor to turn on unexpectedly or maintain
its current state longer than desired.

8. CAUTION: To reduce the risk of overheating and
possible damage to other equipment,
2 )]
DO NOT use to control receptacles.
9. Install in accordance with all national and local
electrical codes.

WARNING! Shock Hazard. May result in serious injury or death.
Turn power OFF at circuit breakers before installing the unit.
Two Line Wiring:
Wiring must comply with NEC code for wiring Multiple Branch Circuits: Where two or more branch
circuits supply devices or equipment on the same yoke, a means to simultaneously disconnect
the ungrounded conductors supplying those devices shall be provided at the point at which the
branch circuits originate.
