Dozor-4 Control, Fire Safety and Fire-Extinguishing System Control Receiving Device
Four-loop device Dozor-4 designed for creation of fire and security alarm system with connection of automatic fire suppression actuating devices.
Dozor-4 operates with Eridan branded explosion-proof devices, such as heat detectors, call points, annunciators and indicating devices manufactured by Eridan, CJSC.
The advantages of this system consist in equipment compatibility, high reliability of actuation both by detectors electronic key closing and opening, versatility, ease of installation and maintenance of the offered scheme.
We recommend Dozor-4 in combination with the explosion-proof products of Eridan company for our customers - design centers and installation companies specialists, trading companies dealers and managers.
Key features
- architecting of one direction of gaseous, powder or earosol fire suppression without additional devices;
- current in the fire-fighting agent start circuit is up to 2.5A;
- start and alert circuit control;
- minimizing possibility of false actuation of smoke sensors virtually to zero by means of applicaion of a special algorithm;
- built-in offline supply source, automatic power reserve, internal battery, battery tripping in case of discharge;
- the user can select any of the existing 15 modes of operation when configuring the device;
- reserver power output +12V, 400 mA with electronic protection against short circuiting for eneergizing of external devices and sensors;
- recording of events in non-volatile memory with possibility of subsequent transfer to the PC;
- device self-monitoring in the moment of initial activation
- dust and moisture proofness IP30.
