SATEL

The MSD-350 detector can detect the early stages of fire development when there is some visible smoke. It is designed to work as a stand-alone device or within the MICRA wireless system. The detector meets the EN 14604 requirements. This manual applies to the detector with electronics version 1.2. It is supported by:
· PERFECTA alarm control panels (WRL models),
· PERFECTA-RF module,
· VERSA-MCU controller,
· MTX-300 controller,
· MICRA alarm module (firmware version 2.02 or newer).

1. Features
· Visible smoke sensor. · Detection of dirt in the optical chamber. · Encrypted radio transmissions in the 433 MHz frequency band. · Red LED indicator. · Built-in sounder. · Detector test / reset button. · Battery status control. · Tamper protection against enclosure opening (when the detector works within the
wireless system).
2. Description

Fire alarm
Smoke detection The optical method is used for the detection of visible smoke. When the concentration of smoke in the optical chamber exceeds a given threshold, a fire alarm is generated. The detector automatically compensates for gradual changes in the optical chamber caused by deposition of dust.
Fire alarm signaling The fire alarm is indicated by the LED indicator (ON) and the built-in sounder (continuous sound) for 5 minutes.
Resetting the fire alarm Press the test / reset button (Fig. 1) to clear the alarm. The fire alarm signaling will be turned off for 5 minutes.
Operating mode
Use the jumper to set the operating mode (Fig. 2): · jumper on (by default) ­ working within the MICRA wireless system (radio transmissions
and tamper protection are enabled). · jumper off ­ stand-alone mode (radio transmissions and tamper protection are disabled).

Working within the wireless system
Radio transmissions Every 15 minutes, the detector sends information about its state (periodical transmission). Additional transmissions are sent in case of: · fire alarm, · fire alarm restore, · tamper alarm, · tamper alarm restore.
Tamper alarm Opening the enclosure (opening the tamper switch) will generate a tamper alarm. It is indicated by the LED indicator (ON for 2 seconds).
Test mode The test mode is turned on for 20 minutes after inserting the battery or opening the enclosure (tamper switch). When the detector is in the test mode, the LED indicator additionally indicates periodical transmission.
Detector test If you want to test the detector operation, press the test / reset button (Fig. 1). You will hear a short beep. A fire alarm should be generated soon after.
Detection of dirt in the optical chamber The detector is monitoring the state of the optical chamber. Deposition of dust in it may lead to malfunctioning of the device. When the optical chamber requires cleaning: · LED indicator flashes 2 times every 30 seconds, · each radio transmission contains information about dirt in the optical chamber.
Battery status control The detector is monitoring the battery voltage. When the battery voltage is lower than 2.75 V, i.e. the battery is low: · every 30 seconds LED indicator flashes 3 times and the sounder produces 3 beeps, · each radio transmission contains information about low battery.
LED indication The LED indicator (Fig. 1 ) indicates: · fire alarm ­ ON for 5 minutes,

· dirt in the optical chamber ­ 2 flashes every 30 seconds, · low battery ­ 3 flashes every 30 seconds. When the detector works within the MICRA wireless system, the LED indicator also indicates: · tamper alarm ­ ON for 2 seconds, · periodical transmission ­ single flash (only in the test mode).

Acoustic signaling
Built-in sounder indicates: · fire alarm ­ continuous beep sound for 5 minutes, · low battery ­ 3 beeps every 30 seconds, · start of the detector test ­ single beep.

3. Installation

3.1 Tips for installation
· The detector should be installed indoors, in spaces with normal air humidity.
· Do not install the detector outdoors.
· The detector should be installed on the ceiling, as close as possible to the center of the room.
· Do not install the detector in places with high concentration of dust and/or formation and condensation of water steam.
· Do not install the detector near heaters, cookers, fans or air-conditioner outlets.
· Do not install the detector in places where there is no unobstructed movement of air (e.g. in recesses, niches, etc.).
· If the detector is to work within the wireless system, when selecting the place of installation, take into consideration the range of radio communication (so that radio transmissions from the detector can reach the receiver).
· Thick walls, metal partitions, etc. reduce the range of the radio signal. · It is not advisable to install the detector in close vicinity of electrical systems, because it
can adversely affect the range of radio signal.
· If you are using a double-sided mounting tape, remember to press it properly.

3.2 Installation
The detector enclosure cannot be closed without the battery inserted.
There is a danger of battery explosion when using a different battery than recommended by the manufacturer, or handling the battery improperly.
Do not crush the battery, cut it or expose it to high temperatures (throw it into the fire, put it in the oven, etc.).
Do not expose the battery to very low pressure due to the risk of battery explosion or leakage of flammable liquid or gas.
Be particularly careful during installation and replacement of the battery. The manufacturer is not liable for the consequences of incorrect installation of the battery. 1. Remove the plastic dust cup. 2. Turn the cover counter- clockwise (Fig. 3) and remove it (Fig. 4).

3. If the detector is to work as a stand-alone device, remove the jumper (Fig. 2) and skip the steps 5-7.
Remove the jumper before installing the battery. After the battery is installed, removing / placing the jumper has no effect on the detector operation.
4. Install the battery. 5. Register the detector in the wireless system (see the manual for PERFECTA control
panels / VERSA control panels / MTX-300 controller / VERSA-MCU controller / MICRA module). 6. Place the detector where you are planning to install it. 7. Close and open the tamper switch. If the transmission from the detector is received, continue with the installation. If the transmission from the detector is not received, select a different mounting location and repeat the test. It may be sufficient to shift the device ten or twenty centimeters. 8. If the detector is to be mounted on the ceiling using a double-sided mounting tape (Fig. 5): – stick the tape to the enclosure base and keep pressing for several seconds. – stick the enclosure base to the ceiling and keep pressing for several seconds.
The surfaces to be joined using a double-sided tape must be clean and dry. They must be free from dust and grease.
9. If the detector is to be mounted on the ceiling with screws (Fig. 6): – place the enclosure base against the ceiling and mark the location of the mounting holes. – drill the holes in the ceiling for wall plugs (anchors). The wall plugs provided with the detector are intended for concrete or brick. For other types of surface (drywall, styrofoam), use other appropriately selected wall plugs.
– secure the enclosure base to the ceiling with screws.

If any work that may cause dirt to build up in the optical chamber is being carried out on the site, put a plastic dust cover on the detector. Remove it after the work is finished.
4. Maintenance
The detector should be subject to regular checks to ensure it is working correctly. The periodic checks should be carried out at least every 6 months. To check whether the detector is working correctly, press the test / reset button (Fig. 1). A fire alarm should be generated.
5. Cleaning the optical chamber
It is recommended to clean the optical chamber at least once a year. Cleaning the chamber is necessary when the LED indicator indicates dirt in the chamber (2 flashes every 30 seconds). 1. Remove the cover locking screw and open the detector enclosure (Fig. 3 and 4). 2. Remove the battery. 3. Unplug the sounder from its socket on the electronics board (Fig. 7). 4. Pull the release lever (Fig. 8) to unlock the electronics module and turn it
counter-clockwise (Fig. 9). 5. Remove the electronics module with the optical chamber (Fig. 10). 6. Release the mounting catch (Fig. 11) and remove the optical chamber cover (Fig. 12). 7. Using a soft brush or compressed air, clean the labyrinth in the cover, as well as the base
of the optical chamber, paying attention to the recesses where LEDs are installed. 8. Replace the optical chamber cover. 9. Lay the sounder wires in the appropriate grooves. 10. Secure the electronics module with the optical chamber in the cover and turn it clockwise. 11. Plug the sounder into its socket on the electronics board (Fig. 7). 12. Install the battery.
