Introduction
The LGHW3020 hard wired Passive Infra Red Detector (PIR) has been designed to
meet the newest and most demanding requirements of the CCTV market. These detec-
tors provide versatility and surpass the requirements needed for a BS8418 system.
Inside the PIR is a powerful microprocessor which uses logic to determine the validity of
an activation. With this technology nuisance alarms are greatly reduced.
In addition, there are two pyro sensors which split the zones and can be gated either as
(A + B) or (A or B)
The PIR also contains a shock sensor to detect physical attack and a three axis sensor to
detect unauthorised re-orientation and removal from the wall. IR transmission detects
masking (cloak) and a light and thermal sensor allow the detector to compensate for the
outdoor environment.
Operating voltage is 12 Volts DC.
