Remote LED enable/disable

The LED can be enabled/disabled remotely, if the LED has not been enabled using the LED ON/OFF pins. The
LED terminal is provided to allow remote LED enable/disable. The LED is enabled, when the terminal is
connected to the common ground, and disabled, when the terminal is disconnected from the common ground.
You can connect to the LED terminal an OC type control panel output programmed e.g. as the S
, BI or Z
STATUS SWITCH

Alarm memory

If the LED is enabled, the detector can indicate the alarm memory. The MEM terminal is provided to allow the
alarm memory feature enable/disable. The feature is enabled, when the terminal is connected to the common
ground. The feature is disabled, when the terminal is disconnected from the common ground. If the alarm
memory feature is enabled and an alarm occurs, the LED will start blinking. Indication of the alarm memory will
continue until the alarm memory feature is enabled again (the MEM terminal is connected to the common
ground). Disabling the alarm memory feature will not stop the alarm memory indication. You can connect to the
MEM terminal an OC type control panel output programmed e.g. as the A
