INTRODUCTION ELRO HOME PIR PET-IMMUNE MOTION SENSOR AG40PP11:
The PIR Pet-immune Motion Sensor AG40PP11 is designed for use with the AG4000 ELRO Home
Alarm System.
PIR Motion Sensor:
Tamper
PIR sensors are designed to detect movement. This sensor features Test
pet immunity however, meaning that your pet moving around will not cause
false alarms.
Installing your home PIR Motion Sensor:
First, the battery has to be inserted into the device. To do this, first unscrew the screw at the bottom of
the sensor so you can remove the back plate. After removing the back plate, place the CR123A 3V
lithium battery in the sensor in the way shown in the picture above. Under normal conditions, the battery
will typically have a life of 3 years. After powering on, the PIR will warm-up for 2-3 minutes. The LED
will flash during this time. When the warm-up has finished, the LED will stop flashing. Next press and
hold the small black test button for at least two seconds to make the PIR detector enter test mode. When
in test mode, if you walk around the area the unit is covering, the LED will flash for 0.5 second (normally,
the LED will not flash when it detects movement). The control panel will also be notified of movement
being detected. If no movement is detected for more than 3 minutes, the PIR detector will exit test mode
and enter normal mode again.
Note:
Under test mode the LED will flash when the PIR detector is triggered. The LED flash in test mode
only lasts for 0.5 second. When the unit has a low battery, the LED will flash for one second. In normal
mode the PIR will only send a new signal after two minutes have passed since being triggered.
Pet immunity:
The sensor comes with a pet immunity mechanism immunity mechanism so that small pets or other
animals will not trigger the detector and cause false alarms. The mechanism works by detecting
height/length, therefore a pet that is taller than 60cm or longer than 90cm will trigger the PIR motion
sensor. You can see this in the image shown below.
Mounting the PIR motion sensor:
When determining where to place the detector, there are various factors to consider:
1. The detector must not be placed facing a window that lets in direct sunlight. PIR detectors are
not suitable for use in sunrooms or greenhouses.
2. Do not place the detector in a place where a ventilator is in its line of sight.
3. Do not place the detector directly above a heat source (e.g. fire, radiator, boiler, etc.)
4. Where possible, mount the detector in the corner of a room, so that the logical path of an
intruder would cut across the detection pattern. PIR detectors are better at detecting
movements across their field of view, than at detecting movement directly towards or away
from the unit.
