energy save – after sending information about the alarm caused by opening the reed switch
contacts or opening the additional input, the next transmission containing information on
this alarm will be sent after 3 minutes at the earliest. Tamper alarms are always sent.
test – the magnetic contact operates like in the normal mode, but the alarms are signaled by
the LED (the LED is lit for 2 seconds).
To select between normal mode and energy saving mode, use the E-SAVE MODE pins
(Fig. 1). The test mode is turned on for 20 minutes after inserting the batteries or opening the
tamper contact.
Every 15 minutes, the detector sends a transmission containing information on the status of
the active reed switch, input, tamper contact and battery. Periodic transmissions are used to
monitor presence and operation of the detector. In the test mode, this transmission is
indicated by the LED lighting for 80 milliseconds.

1 - detector configuration pins:
E-SAVE MODE - operating mode selection:
pins shorted – energy save mode;
pins open – normal mode.
SIDE SWITCH - selection of active reed switch:
pins shorted – side reed switch;
pins open – bottom reed switch.
2 - additional input terminals. An NC type hardwired detector can
be connected to the input or else the terminals must be shorted.
3 - tamper contact.
4 - CR123A battery. The detector checks the battery status. When
the voltage is lower than 2.6 V, the low-battery information is
sent during each transmission.
5 - location of the side reed switch (mounted on the other side of
the electronics board).
6 - location of the bottom reed switch (mounted on the other side of
the electronics board).
4. Installation
There is a danger of battery explosion when using a different battery than
recommended by the manufacturer, or handling the battery improperly.
Be particularly careful during installation and replacement of the battery. The
manufacturer is not liable for the consequences of incorrect installation of the
battery.
The used batteries must not be discarded, but should be disposed of in
accordance with the existing rules for environment protection.
The device is designed for indoor installation. The detector should be mounted on a fixed
surface (e.g. window or door frame), and the magnet on a movable surface (e.g. window or
door). Mounting the magnetic contact on ferromagnetic surfaces and/or near to strong
magnetic and electrical fields is not advisable, because it can result in malfunctioning of the
device.
1. Open the enclosure (Fig. 2).
2. Configure the detector by means of jumpers.
3. Install the battery and register the detector in the MICRA alarm module (see the manual
for MICRA alarm module).
