1. Basic requirement of system installation design
(1) Suitable types and models of detectors should be adopted during
installation design period according to the user requirement of
defense areas.
(2) The installation location, angle and height of a detector should
be determined according to the effective zone of the detector. The
detector should be installed in a hidden location in compliance with
the defense requirement as for as possible.
(3) The wiring should be as hidden as possible so as not to be
damaged. If the exposed wiring is inevitable, conduits or plastic
pipes should be used to protect the wires from the damage caused by
rodents (e. g., a mouse).
(4) The model and specification of detectors and cables at each zone
as well as the usage of every color wire of inside cables should be
labeled on the constructional drawings.
(5) The constructional drawings should be archived for system
maintenance.
2. System installation and debug
(1) Installation requirement of an infrared detector
--The infrared detector has the highest sensitivity when a human
body moves parallel with the mirror surface and the sensitivity is
the lowest when a human body moves vertically against the lens. As
a result, the angle and height against the horizontal surface should
be noted during installation, which will greatly affect the defense
area. The installation height and angle are shown as follows:
--Stand off warm or cold sources, e. g., warm air or cold air outlet,
air-condition outlet, electric radiators, air-radiators, air-cooling
