c) About the wireless PIR detector
The detector is a high quality infrared movement detector, which is battery operated and communicates with the
Watchguard SMS 2010 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.
d) Tips for positioning
Mount the detector on your wall at a minimum height of 1.8 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
Main Control Unit
. 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!
The detector is not waterproof and is designed for indoor use only.
1. Firstly, the mounting bracket must be fixed to the wall
using the self-tapping screw. Mounting should be at a
minimum height of 1.8 metres and maximum of 2.1
metres.
2. Drill a 5mm diameter hole (at least 30mm deep) into
the wall for mounting the detector bracket/socket
base.
3. Push the wall plug into the hole then screw in the
mounting bracket. It will clip into the base.
4. The detector can now be clipped onto the swivel
bracket. See diagram below.
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. You can check how well the detector is functioning, by performing a walk test.
