Vigilante II Series Alarm Annunciators
Models in stock
from $524.00
The VigilanteĀ® II PD158 alarm annunciator provides alarming and monitoring capabilities for all of your level, pressure, flow, and other process switches. The PD158 has eight (8) inputs and accepts inputs from relays, float switches, digital outputs, and many other discrete (on/off) devices. It can be field programmed for all common ISA alarm sequences including first out indication and provide alarm signaling through front panel LEDs and a built in 85 dB horn. It features a NEMA 4X front, 2 SPDT relays for alarm activated devices, wide operating temperature range, and sunlight viewable alarm indicators. Custom printed message labels can be included with your order at no additional charge.
- 1/8 DIN Mount
- 4 or 8-Point Monitoring
- All Common ISA Sequences


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, and can be supplied with free custom printed message labels by completing this form.
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.
