MMD-300
WIRELESS MAGNETIC CONTACT
mmd300_en 03/12
The MMD-300 magnetic contact can detect opening of a door, window, etc. It can be used in
conjunction with the MICRA alarm module with firmware version 2.02 or newer. This manual
applies to the device with electronics version 1.2 or newer.

3. Description
Opening the reed switch contacts after the magnet is moved away, opening the additional
input, or opening the tamper contact will trigger an alarm. Information on the alarm is send by
radio to the MICRA alarm module.
The magnetic contact can work in the following modes:
normal – each alarm results in sending a radio transmission.

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.

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).

4. Select the place of installation. Check that the transmissions from the detector placed at
that point reach the MICRA alarm module. In order to send a transmission, close and
open the tamper contact. If the alarm transmission is received, continue with the
installation. If the alarm transmission is not received, select a different mounting location
and repeat the test.
5. If a detector is to be connected to the additional input terminals, make a hole in the
enclosure base, run the wires through the hole and fasten them to screw terminals. The
maximum permissible length of wires: 3 m.
6. Using wall plugs (screw anchors) and screws, fasten the enclosure base to the mounting
surface.
7. Secure the magnet, taking into account the maximum permissible distance from the reed
switch (see Fig. 4).
8. Close and open the tamper contact to activate the test mode, and then close the detector
enclosure.
9. Check whether the LED lights up after moving the magnet away (i.e. opening a window or
door). If the additional input is used, make sure that violation of the detector connected to
it will cause the LED to light up.
