MSD-300
WIRELESS SMOKE AND HEAT DETECTOR
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
alarm shop
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).

30 °C/min
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.
