UШК-02 Optical Indicator Control Device for Fire Alarm Systems

USHK-02 devices are designed to be used as optical indicators of green (yellow) colour, included in series with the load (e.g. terminal elements) in fire and intruder alarm loops or power supply lines, in order to control the presence of current in the circuit. The USHK-02 devices are intended for use as optical indicators of green (yellow) colour included in series with the load (e.g.

terminal elements) in fire and intruder alarm loops or power supply lines in order to monitor the presence of current in the circuit. In USHK-02 an optical indicator of green (yellow) luminescence colour is used. Presence of two additional contacts (3 and 4), connected together, can be used for installation of external additional elements (e.g.

terminating circuits of loops).
