INSTRUCTION
Occupancy sensor
IR24-P is a passive infrared occupancy sensor suitable for use in “on demand”
control of ventilation systems or in intrusion alarm circuits.
Installation
For best coverage IR24-P should be placed 6…8 feet above floor level in a
location with an unhindered view of the area to be monitored. Avoid exposure
to direct sunlight or
other powerful head sources. For corner mounting the two corner mounting holes
n the casting may be used. For other wall mounting or for ceiling mounting use
the supplied mounting bracket. Fasten the bracket according to the appropriate
figure. Fasten the unit to the bracket and lead the cable through the access
tube in the bracket and through the cable hole in the housing. Align the unit
and llock in position by tightening the locking screw on the bracket. Replace
the front cover.
Wiring
Supply voltage:…………………….. 24 V AC/DC +2 V
Power consumption:…………………. 5mA @ 24 V AC
Relay:………………… Form C, 0.2 A, 30 V DC
Functions
IR24-P is equipped with adjustable ON- and OFF-delays. IR24-P is normally in
standby mode wtih the output relay unactivated. On detecting a movement the
ON-delay is activated. The relayremains unactivated. When the ON-delay time
expires the IR24-P enters a 1-minute waiting period. If no movement is
detected during the waiting period the IR24-P revers to standby mode. If
however a movement is detected during the waiting period, the output relay
will be activated and the OFF-delay initiated. Any detection during of OFF-
delay will restart the delay time. If for example the OFFdelay will restart
the delay timer. If for example the OFF-delay has been set to 5 minutes the
relay will remain activated until 5 minuts after the last detection.
Thereafter the IR24-P reverts to standby mode. Setting of the delay times is
done using two jumpers on the PCboard. Delay times as in table below.
| A| B| C| D| E| F
---|---|---|---|---|---|---
ON| 0 sec.| 10 sec.| 30 sec.| 1 min.| 5 min.| 10 min
OFF| 10 sec.| 1 min| 5 min.| 10 min.| 20 min| 30 min
Function test
On completing the installation a function test should be run. Connect supply voltage and wait for 25 seconds for warm up. The green LED will blink during warm up. Move about over the area to be monitored. the red LED will indicate detection. If detection seems unsatisfactory the unit may need realingment.
