PSZ-4D optical/acoustic alarm device
Sygnalizator optyczno-akustyczny PSZ-4D
The PSZ-4D alarm device is intended for optical and acoustic signalling of alarm conditions occurring at low-voltage outputs of control devices. The alarm device can be installed both indoors and outdoors. It cannot be used in areas defined as explosion hazard zones. The acoustic signal source is a piezo transducer generating a pulsed and modulated sound of high volume. The transducer's control system allows for two-stage intensity adjustment. The optical signal source is provided by ultra-high luminance LEDs. The diodes are divided into two sections, so that a failure of the diode of one section will not disable the illumination of the diodes of the other section. The alarm device's electronics, made in surface mount technology (SMT) and protected with an additional cover against mechanical impact and adverse effects of atmospheric factors, guarantee very high reliability of the device.
