UK-4
Product description 
The end device UK-4 is designed for visual control of the presence of supply voltage (12 V) in a 4-wire fire alarm loop, as well as disconnection of the end resistor in the signal circles of this loop when the supply voltage fails.
- UK-4 provides galvanic decoupling of power supply circuits and signal circuits with the help of a transistor optocoupler.
- Depending on the method of connecting the signal circuits to the output terminals of UK-4, the possibility of generating a "FAILURE" signal is provided in the signal circuits of the fire alarm loop, both with constant current and with alternating sign signal generation.
