4-input optical and acoustic alarm station for help request luminous buttons, to be installed inside coldrooms.
Two of the inputs can be used by refrigerator gas detectors to be installed in the compressor room.
The system is powered by the 230 V~ mains supply and incorporates a battery that guarantees its operation in the
event of a power failure.
The unit constantly controls the connection state of the buttons and/or detectors, warning if this connection is
