2 MSD-300 SATEL
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.
