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

configuration pins for detector outputs:
the built-in resistors are to be used – place the jumpers as shown in Fig. 2 (connect the outputs as shown
in Fig. 10),
the built-in resistors are not to be used – place the jumpers as shown in Fig. 3 (connect the outputs as
shown in Fig. 9).
tamper switch.
scale for positioning of pyroelectric sensor against the lens (see: Fig. 8).
fixing screw hole.
red color LED to indicate:
alarm – ON for 2 seconds,
alarm memory – blinking rapidly,
trouble – ON,
warm-up – blinking slowly.
LED enable/disable pins. The LED is enabled, if the jumper is placed over the pins (the pins are shorted).
dual element pyrosensor. Do not touch the pyroelectric sensor, so as not to soil it.
potentiometer for sensitivity adjustment.
