Multi-Voltage Relays

Relays let a duct or spot detector do something on alarm: shut down a fan, close a damper, release a door holder, or trip an auxiliary circuit. System Sensor's multi-voltage relays cover single SPDT (R-10 series) and DPDT (R-20 series) contacts and four-gang SPDT (R-14 series) and DPDT (R-24 series) versions for switching several loads from one alarm output, each with activation LEDs for quick troubleshooting. The PR-1, PR-2, and PR-3 are epoxy-encapsulated SPDT relays with an activation LED, built to be tucked into a back box or detector housing.

The EOLR-1 end-of-line relay, an encapsulated normally open SPST unit that operates from 9 to 40 VDC, is used to supervise power supplies and other circuits at the end of a run, so a loss of power reports as a trouble at the panel.

Relays pair with the duct detectors and accessories in this section and with i3 spot detectors. Browse the full System Sensor catalog, or contact our team for contact ratings and wiring help.
