DESCRIPTION
Model LRP 180QH is designed to detect human movement at ranges of up to 180 metres. The rugged housing
contains two separate detectors. One detector is similar to the popular REDWALL LRP 100Q quad sensor which
has a detection range up to 100 metres. The other detector is also a ‘quad’ sensor system with a long focal
length optical system specifically designed to detect movement at ranges between 80 and 180 metres.
The LRP 180QH is ideal for use with CCTV surveillance systems which have multi-cameras or domes with pan,
tilt and zoom facilities. The two outputs (near and far) may be used to automatically activate camera pan or
zoom controls to precisely locate an intruder over the full detection range. Alternatively, the two outputs may be
used to direct an operator to a specific area of interest or to activate local floodlighting.
The LRP 180QH comprises two units, the detector head and the control unit which contains three relays for ‘near’,
‘far’ and tamper signalling. The control unit may be located remote from the detector head, for instance at a
control/monitoring area, or may be located close to the detector or camera where direct automatic pan or zoom
is used.
Connection between head and control unit is 4-core screen cable which may be up to 1400 metres. (See cable
chart Fig. 6). Alarm signalling between the detector head and the control unit is by means of simple line current
monitoring which is highly immune to radio and electrical interference.
Fig. 1 shows the coverage patterns of the two detectors. At the recommended mounting height of 8 feet (2.5
metres) there will be an area directly below the unit extending some 6 metres where an Passive Infrared
