MSD-300
WIRELESS SMOKE AND HEAT DETECTOR
msd300_en 10/11
The MSD-300 multisensor detector can detect the early stages of fire development when
there is some visible smoke and/or temperature rise. It can operate as a stand-alone device
or in combination with the MICRA alarm module. This manual applies to the detector with
electronics version 1.1 or later.
1. Features
•EN54-7 compliant visible smoke sensor.
•EN54-5 compliant heat sensor.
•Red LED for optical signaling.
•Built-in sounder.
•Test feature.
•Tamper switch (supervised when working in the MICRA system).
2. Functional description
An optical method is used for the detection of visible smoke. When the concentration of
smoke in the optical chamber exceeds a given threshold, an alarm is triggered. The smoke
sensor operating parameters are modified depending on the temperature changes recorded
by the heat sensor (thermistor).
The heat sensor operates according to the requirements of Class A1R (EN 54-5). The alarm
will be triggered after exceeding a certain threshold temperature (54°C - 65°C) or in the event
when the temperature rises too rapidly (see Table 1).

20 °C/min 30 s 2 min 20 s
30 °C/min 20 s 1 min 40 s
Table 1. Response time limits for the heat sensor.
The alarm is indicated visually (LED steady light) and acoustically (intermittent sound) for 2
minutes. Pressing the test / reset button (designated with the letter A in Figure 1) during the
alarm will clear the alarm condition. The alarm information is sent by radio to the MICRA
alarm module. After the alarm causes cease to exist, information about the alarm end will be
sent.
Every 15 minutes, the detector sends a transmission containing information on tamper
contact and battery status. Periodic transmissions are used to monitor the presence and
operation of the detector by the MICRA module.

3. Installation
The detector is designed for indoor operation. It should be installed on the ceiling, at
a minimum distance of 0.5 meters from the walls or other objects.
Do not install the detector in places with high concentration of dust and/or
formation and condensation of water steam. The detector should not be
mounted in the vicinity of heaters and cookers.
The detector enclosure can not be closed without the battery inserted.
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 following description applies to installation of the detector which is to work within the
MICRA system. If the detector is to operate stand-alone, skip steps 5 and 6.
1. Remove the plastic dust cap.
2. Turn the cover counter-clockwise (Fig. 1) and remove it (Fig. 2).
3. Remove the battery and remove the protective film from it.
4. Re-install the battery.
5. Register the detector in the MICRA alarm module (see the manual for MICRA alarm
module).
6. Check that the transmissions from the detector placed in the selected mounting location
reach the MICRA alarm module. To send a transmission, close and open the tamper
contact. If the alarm transmission is received, proceed with the installation. If the alarm
transmission is not received, select a different mounting location and repeat the test.
7. Using wall plugs (screw anchors) and screws, fasten the enclosure base to the ceiling.
8. Close the detector enclosure.
9. Press and hold down the test / reset button (designated with the letter A in Figure 1) to
make sure that the detector works. Alarm should be triggered after a few seconds.
10.If any other operations which may cause contamination of the optical chamber are being
carried in the facility where the detector is installed, the detector must be temporarily
covered with a plastic dust cap.
4. Cleaning the optical chamber
The detector monitors the state of the optical chamber. Deposition of dust in the interior of
the chamber can in time lead to false alarms. Contamination of the chamber is indicated by
LED (2 flashes every 40 seconds). Information on the chamber soiling is sent to the MICRA
module, which can notify the user about it. In order to clean the chamber, do as follows:
1. If the detector is used in the MICRA system, start the test mode in the module.
2. Turn the cover counter-clockwise (Fig. 1) and remove it (Fig. 2).
3. Remove the battery.
4. Pull aside the mounting catches (Fig. 3) and remove the electronics board with the optical
chamber (Fig. 4).
5. Remove the cover from the thermistor (Fig. 5).
6. Pull aside the thermistor and its leads (Fig. 6).
7. Pull aside the mounting catch of the optical chamber (Fig. 7) and remove it (Fig. 8).
8. Using a soft brush or compressed air, clean the labyrinth in the cover and the base of the
optical chamber, paying attention to the recesses where the LEDs are installed.

9. Replace the cover of the optical chamber.
10.Place the thermistor leads in the respective grooves.
11.Replace the thermistor cover.
12.Secure the electronics board with the optical chamber in the cover mounting catches. The
board must be mounted so that the LED coincides with the light guide/button.
13.Re-install the battery.
14.Close the detector enclosure.

5. Battery replacement
The detector power supply battery (CR123A 3 V) ensures operation for about 3 years. A low
battery status (voltage drop to 2.6 V) is audibly indicated (by a beep every 40 seconds). The
information on low battery is sent to the MICRA module, which can notify the user about it. To
replace the battery, do as follows:
1. If the detector is used in the MICRA system, start the test mode in the module.
2. Turn the cover counter-clockwise (Fig. 1) and remove it (Fig. 2).
3. Remove the discharged battery and dispose of in accordance with applicable
environmental regulations.
4. Install a new CR123A 3 V lithium battery.
5. Close the detector enclosure.
6. Press and hold down the test / reset button (designated with the letter A in Figure 1) to
make sure that the detector works. Alarm should be triggered after a few seconds.
