2.4.4 Intelligent Power Saving (IPS) & Normal Mode
This detector has Intelligent Power Saving (IPS). This means that in normal
operation or normal mode the red light will indicate valid movement detection
but the green light will not turn on at all.
Lights will not flash every time you
move in front of the detector.
When the red light flashes on for 1 second,
this means that the detector has picked up and validated body movement (or
an intruder). The detector will now go into IPS mode for approximately 3
minutes. During this time the detector will not trigger and no lights will turn on.
After this 3 minutes of IPS the detector will again be ready to sense for any
movement in the room. If the sensor 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 should be set to sound your siren
for 5 minutes after being triggered.
In summary, the detector will only trigger and flash the red light once
every 3 minutes in its normal operation to save battery life. The green
light will stay off.
2.4.5 Adjusting the Detector Sensitivity
PULSE COUNT SELECT Jumper
ON
Least sensitive – 3
pulse counts
OFF
Most sensitive – 2
pulse counts
The sensitivity of the detector can be changed by either removing the ‘Pulse
Count Select’ jumper or by placing it across both pins. When the jumper is
placed across both pins (default), then the detector is set to 3 pulse counts
(least sensitive). When the jumper is removed or only attached to 1 of the pins,
then the detector is set to 2 pulse counts (most sensitive).
Once you have set the jumper, you must press the tamper
switch in for 1 second then release it for the setting to become
active. Now you can place the front cover back on the detector.
