About The Wireless Passive Infrared Detector (PIRW)
The detector is a high quality infrared movement detector, which is battery operated and communicates with the Watchguard Digital alarm system via radio frequency (RF) transmission. This detector is very easy to install, provides excellent detection sensitivity and has a long battery life (approximately 3 years). This detector transmits four different codes to the main control unit:
1 | Alarm | Sent when a valid movement is detected |
|
|
|
2 | Tamper | Sent when the detector case is opened |
|
|
|
3 | Supervision | Sent every 2.5 hours to the main control unit |
|
|
|
4 | Low Battery | Sent when the batteries need replacing |
|

During the warm up period, (first 3 minutes after installing the batteries) the detector will not respond to the tamper switch or to movement in front of the detector. You must wait 3 minutes before it will respond to movement
This detector has Intelligent Power Saving (IPS). This means that in normal operation the 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) and an alarm code is transmitted. 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.
Tips for positioning
Mount the detector on your wall at a minimum height of 1.2 metres and maximum of 2.1 metres (lower is better).
Always mount your PIRW so that an intruder has to walk across its zones, i.e. walk past the detector, not towards it.
DON’T mount detectors facing glass doors or windows. Always mount above windows and doors to look inside.
DON’T mount detector facing hot areas or areas where the temperature may change suddenly, e.g. open fire places, direct sunlight or air conditioning vents.
Select a location where the detector can provide the best detecting range. Always ensure that you do not cover an area with multiple detectors, so as to avoid simultaneous transmission back to the receiver in your Watchguard Digital Home Alarm System. The receiver can only decode one coded signal at any given time.
If the Main Control Unit is mounted close to metal frames or doors, this may reduce the radio transmitting range. The higher the mounting and straighter the antenna the better the range!
