Introduction

These Quad Element Passive Infra-Red (PIR) Movement Detectors are designed for use with standard wired alarm
system. PIR detectors are designed to detect movement in a protected area by detecting changes in infra-red
radiation levels caused for example when a person moves within or across the detectors field of vision If movement
is detected, the signal contacts "open" and an alarm signal is generated at Control Panel (if the system is armed).

Mounting Location

The PIR is designed for indoor use. It should not be mounted near to large
metal objects or on metal surfaces. It needs to be mounted on a wall or in a
corner at a height of approximately 2-2.5meters for the best general
coverage in an average room. The detector has been designed to avoid
false alarms, nevertheless, it is best to avoid looking directly at sources of
heat such as fires and boilers, and always try to keep away from a window.
A PIR can look at a radiator but should not be sited above one.
Do not site a PIR where its field of view may be obstructed (e.g. by curtains). Also note that PIRs work best when sensing
movement across rather than along their detection beams. You need to consider the need to wire these units back to the Control
Unit.
