extent permitted by the applicable state law, Enerlites shall not be liable to the purchaser or

The Sensor Switch is programmed for Occupancy Mode only.

 

Automatic Turning On/Off the Load

Once the power is on, the load will be turned On according to the 

occupancy settings. The sensor time delay operates as programmed.

 

 When the load turns OFF due to the lack of motion detection, the

 

 load can be turned ON again by occupancy detection or switch

 

 activation.

The Sensor keeps the Load On until no motion is detected plus the 

set time delay, load(s) will be turned Off automatically. 

OPERATION

NOTE: When power is initially applied to the sensor, there is a warm-up

period of up to 1 minute before the LED is active.

 following condition exists:

because of the level of ambient light in the controlled area. To test

whether the Light Level adjustment is the problem, cover the PIR lens

and PIR Activity LED  with your hand to see if the lights turn on. If

the lights turn on, the Light Level setting was keeping  the lights off

(see, “Sensor Adjustment” for readjustment).
