Wire bracket
Product Description
The ceiling-mounted Occupancy Sensor saves energy and adds
convenience by accurately detecting when an area is occupied
or vacant.
This device is wireless, powered by indoor light, and uses a pas-
sive infrared (PIR) sensor to detect motion. The occupancy sen-
sor transmits RF signals that control lighting, HVAC and outlets
to manage energy more efficiently.
Features Include:
▪
Sends wireless messages to other devices whenever motion
is detected
▪
Harvests ambient solar energy to power the sensor and wire-
less communication
▪
Mounts easily on any ceiling material
▪
Works with other sensors for enhanced occupancy tracking
▪
Built-in tests to confirm operation at installed location
▪
Supplemental battery or alternative power supply options for
extreme low-light conditions

Functional Description
If occupation is detected by the permanently active PIR sensor,
a radio telegram indicating the occupied status will transmit
immediately. An internal timer starts to run with a variable timer
length. The timer value may vary between 60 and 300 seconds,
depending on the light level. No radio telegrams will be sent
out when the timer is counting down.
After the timer has finished the countdown, the unit will trans
-
mit again if occupancy was detected during the countdown time
period. If occupancy was not detected, the unit will transmit a
heartbeat signal - sending the unoccupied status with a ran-
dom timing of 2 to 12 minutes. There are two buttons which
allow entrance to a “Walk” or “Light-level” test mode. These
test modes are for installation purposes only and will be exited
automatically after 3 minutes.
