2 | Professional Series Dual Detectors ISC-PDL1-W18G and ISC-PDL1-W18H
Dynamic Temperature Compensation
The detector adjusts PIR sensitivity to identify human
intruders at critical temperatures. Dynamic temperature
compensation detects human body heat accurately,
avoids false alarms, and delivers consistent catch
performance at all operating temperatures.
Cover and Wall Tamper Switch
When an intruder removes the cover or attempts to
separate the detector from the wall, a normally-closed
contact opens to alert the control panel.
Self-adjusting LED
The LED brightness adjusts automatically to the
surrounding light level. A blue light emitting diode (LED)
indicates dual alarms and activates during a walk test. A
yellow LED indicates microwave alarms, and a red LED
indicates PIR alarms.
Remote Walk Test LED
Users can enter a command at the control panel to
remotely enable or disable the walk test LED. Users can
locally enable or disable the walk test LED through the
DIP switch.
Alarm Memory
Alarm memory flashes the alarm LED to indicate stored
alarms for use in multiple unit applications. A switched
voltage from the control panel controls the alarm
memory.
Solid State Relays
Solid state relays send silent alarm output signals to
provide a higher level of security and reliability. An
external magnet will not activate the relay. The solid
state relay uses less current than a mechanical relay,
providing longer standby capacity during a power loss.
Draft, Insect, and Small Animal Immunity
The sealed optic chamber provides immunity to drafts
and insects, reducing false alarms. Small animal
immunity reduces false alarms caused by animals such
as rodents.
Remote Self Test
A remote self test initiates when the walk test input
switches to its true state. The alarm relay and alarm LED
activate for four seconds following a successful test. The
trouble relay activates, and the alarm LED flashes
following a failed test.
Input Power Supervision
When the power is lower than 8 V, a low input power
trouble condition activates the trouble relay and causes
the LED to flash. The trouble condition clears
automatically when power reaches or exceeds 8 V.
Trouble Memory
When the walk test input switches to its true state for
less than two seconds, LED flashes to indicate the most
recent trouble condition. If there is no trouble in
memory, the LED does not flash. After twelve hours, or
after the detector receives a second walk test pulse for
two seconds or less, the LED stops flashing and the
trouble memory clears.
