REGIN ABV24-S-300/D - Control units for smoke detectors 24V
The ABV ..-..- 300 / D series control units are designed for use with S .. and SDD series smoke detectors. The detectors are connected to the control unit via a two-wire loop, which can contain up to 20 detectors. The circuit must be terminated with a resistor in the last detector. The control unit supplies the connected detectors, continuously checks the functions of the detection circuit and in case of smoke detection activates alarm outputs - relays and LED signals. The outputs from the control unit can be used, for example, to control the function of the fan, muffler, to activate an alarm, etc. Mounting on a DIN rail. ABV24-S-300 / D control unit with service alarm, supply voltage 24V AC / DC (designed for S65 series detectors, ie with service control).
