Redwall LRP3020 User Manual

SECURITY ENCLOSURES
REDWALL® LRP 3020, LRP 4010 and LRP 404 P.I.R. DETECTORS
Installation Instructions
DESCRIPTION
Model LRP3020 is designed to detect human movement within a 30° arc at ranges up to 30 metres (95
feet). See Fig. 2.
Model LRP 4010 is designed to detect human movement within a 10° arc at ranges up to 40 metres (125
feet). See Fig.3.
Model LRP 404 is designed to detect human movement within a 4° arc at ranges up to 40 metres (125
feet). See Fig.4.
All detectors may be used to control floodlighting when combined with INTERSWITCH LRP105.
The rugged cast aluminium housing allows use in heavy industrial environments indoors or out.
The units require a 12 volt D.C. nominal supply (11v-16v) drawing approx. 25mA (0.025Amp). Models
4010H/3020H/404H have internal heaters and may draw between 25 and 200mA, between +5°C and -
40°C. Detection output is by electrically isolated form C (change-over) relay contacts having a 30v 1Amp
max. rating.
The mounting base contains all of the connection terminals. Event indicators, security level selector switch
and jack socket for the audio Walk-Tester LRP 1020. The removable cover is tamper protected by a
normally closed microswitch.
The detector head is factory sealed and has NO user controls or access. The swivel bracket allows 180-
degree panning and is locked into position by 3 Allen head screws. A matching Allen key is supplied with
every unit and should be retained for future use.
DUAL BI-CHANNEL SYSTEM
All models use four independent element sensors. These, when combined with the optical system,
produce two independent sets of zones ‘A’ & ‘B’ accurately interleaved so that an intruder crossing the
zones will produce sequential ‘A’ ‘B’ ‘A’ ‘B’ signals. Each pair of elements feeds a separate processing
channel (See Fig.1).
Each channel has an LED ‘event’ indicator and memory. This stores the ‘event’ for approx. 10 seconds.
For normal installations, both memories must have ‘events’ stored before the alarm relay is activated. (‘A’
& ‘B’). However, for high security installations, a switch allows the alarm relay to activate if EITHER
memory has logged an ‘event’ (‘A’ OR ‘B’).
