The USHK-01 devices are designed to be used as remote optical signalling devices (ODD) of red (orange) colour, to duplicate the state of built-in optical indicators of fire detectors of IP212-44, IP212-54, IP212-3M3 and similar types. The design of the devices is a plastic case with a board installed inside, which is fixed to the base by a cover by means of screws.
The board contains an optical indicator, circuit elements and output pads. The device is fixed to the building structures by means of two of four holes in the base, access to which (as well as to the pads) is provided after removing the housing, which is fixed by means of latches.
