The device is intended for continuous round-the-clock work as a part of systems of the fire alarm system, in rooms with adjustable climatic conditions.
The device has four zones for connection of addressless fire announcers with constant control of current whom it is possible to connect to 32 pieces.
The device carries out:
- control of announcers both with normally closed, and with normally opened contact -
- control of sound and light-sound annunciators -
- delivery of signals on shutdown of ventilation and smoke removal -
- delivery of signals on monitors fire extinguishing -
- transfers of notices on the panel of the centralized observation through contacts of the relay "-malfunction" - and "-the fire" - or by a call-back (through MTsA – more than 150 notices or through MTsA GSM (CSD/GPRS)).
- has the stabilized tension in zones which does not depend on a condition of the battery that facilitates calculation of system and increases the maximum number of 2-wire announcers in each zone -
- relay exit for food of 4-wire announcers with output current to 1 A -
- relay exit to annunciators with switching current to 5A and a possibility of food from an external source -
- rechargeable battery with a capacity of 7 A*god-
- has 3 algorithms of verification of drawdown of announcers -
- the device is programmed by means of USB-of a programator
