
).

LED indicator.

Remote LED enable / disable.

Alarm memory.

Supervision of motion detection system and supply voltage.

Tamper protection against enclosure opening.

Adjustable mounting bracket included.
2. Description
The alarm output will turn on for 2 seconds when the infrared sensor (PIR) detects motion.
Supervision features
In the event of the voltage drop below 9 V (± 5%) for more than 2 seconds or the motion
detection system failure, the detector will signal a trouble. The trouble is indicated by the
alarm output turning on and the LED lighting up. Signaling will continue as long as the trouble
exists.
LED indicator
The LED indicates:

warm-up
– flashing for about 30 seconds,

alarm memory
– flashing rapidly,

alarm
– ON for 2 seconds,

trouble
– ON for entire duration of the trouble.
Enabling the LED by using a jumper
If you put a jumper across the LED pins as shown in Fig. 4, the LED will be enabled, i.e. it will
indicate the events described above (the LED cannot be enabled / disabled remotely). If you
put a jumper across the LED pins as shown in Fig. 5, the LED will be disabled, i.e. it will only
indicate warm-up and trouble (but the LED can be enabled / disabled remotely).
Remote LED enable / disable
The LED terminal is provided to allow remote LED enable / disable. When the terminal is
connected to common ground, the LED is enabled. When the terminal is disconnected from
common ground, the LED is disabled.
If the detector is used in the INTEGRA / INTEGRA Plus alarm system, you can connect to
the terminal the OC type control panel output programmed e.g. as “Zone test status” or “BI
switch”.
