Technical Specifications

Electronrts series AN-20 are alarm annunciator specially used for various industrial applications. It is a central collection point of a persistent surveillance system watching sensing devices of many types & functions. Pressure & temperature switches, under / over voltage relays, status contacts and many other unrelated devices actuate the annunciator by means of their respective electrical contacts. This annunciator is reliable & compact system as per standards. Multi-coloured windows provided for easy differentiation of trip & non-trip or alarm & trip faults. System accepts potential free contacts as its input which may be of NO / NC type selectable by DIP switch. System incorporates a group of super bright LEDs instead of twin filament lamps in each window and specially designed power supply for high noise and wide input supply variations.
