Test Mode for the Passive Infrared detectors
It is vital that the detector is tested carefully for each installation. At
25°Celsius, the detector should have a detection range of approximately 10
metres and a scope angle of 90°, i.e. 45° either side of the centre position
straight ahead of the lens.
To place the detector in test mode do the following:
•
Remove the front cover off the detector via the clip at the top.
•
The green and red lights will flash together, 6 times, to indicate that the
detector has entered test mode.
•
Replace the front cover.
•
The detector will stay in test mode for 3 minutes.
Once in test mode
Now the detector can be triggered constantly for the next 3 minutes. Walk past
the detector to test the detection range. When movement is detected the
green light will flash to indicate one pulse count when 3 pulse counts are
detected the red light will flash to indicate a valid movement and that the alarm
code signal has been sent back to the main control unit.
Intelligent Power Saving and Normal Operation
This detector has Intelligent Power Saving (IPS). This means that in normal
operation the green light will not flash to indicate pulse counts but the red light
will flash to indicate a valid movement detection, then the detector will go into
IPS mode for approximately 3 minutes. During this time the detector will not
trigger and no lights will turn on. After these 3 minutes of IPS the detector will
again be ready to sense for any movement in the room. If the detector detects
another valid body movement anytime after the 3 minutes of IPS then it will go
back into IPS mode again for 3 minutes and so on. There is no need for the
detector to trigger more than once every 3 minutes as your alarm system is set
to sound your siren for 5 minutes after being triggered.
In summary, when in normal operation the detectors will only trigger and
flash the red light once every 3 minutes to save battery life. The alarm
system will notify you if any batteries need replacing.
