Alarm indicator WZ-31
The WZ-31 alarm indicator is designed for optical indication of the alarm state of one or more detectors in fire alarm systems. It can be connected to the bases of both conventional and addressable detectors, especially in locations where the detector is not visible, such as above suspended ceilings or in cable ducts. The indicator is suitable for use with POLON-ALFA addressable and conventional detectors.
The WZ-31 signals the alarm mode of a detector or a group of detectors with a red LED light. In conventional systems, the LED lights continuously, while in addressable systems, it flashes. The indicator is powered by the detector in alarm mode and should be installed in easily accessible locations, such as corridors, when the detector itself is hidden or difficult to access. The device is installed without a base and features two terminals: one for power supply minus and one for control from the detector.
