The Passive Infrared Detector; Important Notes - Watchguard N517Series II User Manual

1.1. The Passive Infrared Detector

The detector is a high quality infrared body movement detector, which is battery
operated and communicates with the Watchguard Home Alarm System via radio
frequency (RF) transmission. This detector is 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 unit:
• Alarm – sent when a valid movement is detected
• Tamper – sent when the detector case is opened
• Supervision – sent every 2.5 hours to the main unit
• Low Battery – sent when the batteries need replacing

IMPORTANT NOTES

• NEVER touch the pyro detector with your fingers
• 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 properly.
• 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
(see section 3.8.2. for more information).
• The wire, which runs around the edge of the detector, is the antenna. Do not
touch, remove or cut this wire
