Programmable Type Alarm Annunciator is designed as an alarm system with integral redundant supplies, audible, relays and pushbuttons. The Annunciator has the feature that each channel is equipped with an integral relay, facility, typically used to initiate inputs to third party devices. The Annunciator has the feature that all inputs are optically coupled and the input voltage is 24 VDC but 48 and 250 VDC can be availed. The Annunciator has dual horn relays and each pair of alarm ways can be selected to operate either a critical or non-critical integrally mounted horn relays. The Annunciator comes equipped with sleep mode which is typically used in substation applications where the visual and audible outputs are disabled during unmanned periods to reduce drain on the station batteries. The Annunciator has programmable alarm sequence, signal duplicating relays, dual horn relays. The Annunciator has LED display. The Programmable Type Alarm Annunciator consumes less power.
