REGIN ABV-S-300/D - Control units for smoke detectors 230V
The control units of the ABV ..-..- 300 / D series are intended for use together with smoke detectors of the S .. and SDD series. The detectors are connected to the control unit by means of 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 power to the connected detectors, continuously checks the functions of the detection circuit and, in the case of smoke detection, activates the alarm outputs - relays and LED signals. The outputs from the control unit can be used, for example, to control the function of the fan, damper, to activate the alarm signaling, etc. DIN rail mounting. Control unit ABV-S-300 / D with service alarm, supply voltage 230V AC (designed for detectors of the S65 series, ie with service control).
