4 MSP-300 SATEL
Periodic transmissions
Every 15 minutes, the siren sends a transmission with information on the current status of the tamper switch
and battery. Periodic transmissions are used to monitor presence and operation of the siren.
Power supply
The siren is powered from a 3.6 V lithium thionyl chloride battery. It is a high-current battery, characterized by
high capacity. The battery is offered by SATEL.
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.
Given the specific nature of the battery, it must be properly initialized to reach the required
performance. Therefore, when connecting a new battery, always follow the procedure below:
1. Press and hold down the tamper switch.
2. Connect the new battery.
3. When the leftmost LED on the siren starts flashing every second, release the tamper switch.
Flashing of the leftmost LED indicates that the first phase of battery initialization is in progress. After 5 minutes,
when this phase is completed, the siren is ready for work. The second phase of battery initialization lasts 3
hours, without however limiting functionality of the siren. This phase is signaled by two flashes every 30
seconds.
4. Installation and start-up
The siren must be installed on the wall, high above the floor, at a hard to access location, so as to minimize the
risk of tampering. Make sure that some free space is left above the siren (at least 2.5 cm). Otherwise, it will be
impossible to replace the cover.
1. Remove the cover locking screws.
2. Lift up the enclosure cover by approx. 60º and remove it (see Fig. 3).
3. Connect the battery and register the siren in the control panel (see the PERFECTA control panel installer
manual) / the controller (see the MTX-300 manual).
Note: The battery is to be connected just before installing the siren.
4. Replace the siren cover.
5. Place the siren in the location intended for its installation.
6. Make sure that transmissions from the siren reach the control panel / the controller and check the level of
radio signal (see the PERFECTA control panel manual / the MTX-300 manual). In order to send a
transmission, open the tamper switch of the siren. If the transmission fails to be received or the signal level
is lower than 40%, select another installation place and repeat the test.
7. Remove the siren cover.
8. Disconnect the battery.
9. Move aside the catches holding the electronics module and remove it.
10. Place the enclosure base on the wall and mark the location of mounting holes (see Fig. 2). Be sure to take
into account the tamper mounting hole.
11. Drill the holes for wall plugs (screw anchors).
12. Secure the enclosure base to the wall with wall plugs (screw anchors) and screws. Remember about the
tamper mounting hole. The wall plugs (screw anchors) and screws delivered with the siren are intended for
brick, concrete and similar mounting surfaces. For other surfaces (e.g. drywall, wood, styrofoam), use other
wall plugs (screw anchors), as required.
13. Secure the electronics module in the enclosure base.
14. Connect the battery.
15. Replace the siren cover and fasten it with screws.
16. Test the siren for proper operation.
