2.2.3. Mini Passive Infrared Low and Medium power
The Sensor detects the movement of heat in the infrared spectrum of light. In other
words a source of heat such as a human moving past the Sensor field of view will cause
the Sensor to detect and a signal will be sent to the Control Panel Control panel. The
Sensor will detect movement up to 8-12 meters away from the device, at a hight of
1,8m, and up to 100 degrees wide.

Passive Infrared Wide Angle Sensors).
2.2.4. Universal Transmitter (Door Guard). Low and High Power.
The Door guard, DG, is actually a universal transmitter with integral panic button and
connections for a magnetic contact switch or similar device. The low power DG will send
a signal to the control panel when the magnet moves away from the magnetic switch,
for example, when a door or window is opened (N/C connector). The Low power DG is
equipped with an internal blue strip connector for N/C connections. The high power DG
is also equipped with an internal blue strip connector for N/O and N/C connections. The
high power DG has a mercury tamper switch.
