PD150 Vigilante II Series Alarm Annunciator

Brand: Precision Digital Corporation

The Vigilante II annunciators are compact, panel-space saving, four and eight channel annunciators loaded with features found previously in annunciators three or four times their size. 

Yet despite all the traditional annunciator features that are included in the Vigilantes, they are still very much low-cost, easy to use alarm annunciators perfect for replacing stand-alone lights!

The Vigilantes are housed in shallow depth, 1/8 DIN enclosures for easy and convenient mounting. They can be programmed for all the common ISA alarm sequences, accept switch, transistor, and logic level inputs.

The Vigilantes' industrial-grade design, NEMA 4X front, wide operating temperature range, and sunlight readable alarm indicators make them well suited for outdoor alarm applications. 

Front panel buttons and screw terminal connectors located at the rear of the instrument are provided for Silence, Acknowledge, and Reset functions. 

A built-in horn provides audible indication of alarm condition and up to two relays can be used to control external devices such as beacons, horns, or buzzers.
