4 Wire Smoke Detector With Relay

For that reason an external power relay must be used with a 4 wire smoke.

4 wire smoke detector with relay.

System sensor 4wtr b photoelectric i3 smoke detector 4 wire thermal sensor form c relay upc. 12 24 v non polarized 2 wire. 4witar b yes 4 wire 50 ma smoke detector specifications electrical specifications operating voltage nominal. 10 v to 35 v maximum ripple voltage 30 of applied voltage peak to peak.

This resistor is seen electrically back at the main alarm panel and verifies that the smoke detector wiring is unbroken. Two leds on each detector provide local 360. This detector is designed to provide open area protection and to be used with most security alarm control panel. 4w b products system sensor system sensor.

4 wire smoke detector with relay output yt142. The alarm relay contacts of the 4 wire smoke detector are connected to the class b or class a zone wiring of the fire alarm system. The detectors are photo electronic detector uses a state of the art optical sensing chamber. This is provided by the power supervision relay.

Two leds on each detector provide local 360 visible alarm indication. Instead the 4 wire smoke detector s reset is sent through the auxiliary power source. 4wtrb bk 4wtrb the 4wtr b is a 4 wire photoelectric i3 smoke detector with thermal sensor and form c relay. Once a 4 wire smoke activates the only way to reset it is to drop power to that device.

4 wire smoke heat detector with relay output ft143. When alarmed just like a conventional heat detector pull station or waterflow switch the relay contacts short out the zone wires. Basically the alarm output relay contacts of the 4 wire smoke detector electrically isolate the smoke detector from the zone wiring of the idc. This detector is designed to provide open area protection and to be used with most security alarm control panel.

8 5 v to 35 v 4 wire. This detector is designed to provide open area protection and to be used with most security alarm control panel. Unlike the 2 wire smoke a 4 wire smoke must also supervise the second pair of wires used for supplying power. Two leds on each detector provide local 360 visible alarm indication.

Basically to reset a 4 wire smoke detector the auxiliary 24 volt power supply has to turn off and on. System sensor is a global manufacturer of fire and life safety devices in smoke detection carbon monoxide detection and notification technology. 4 wire smoke detector with relay output dc powered yt 142 the detectors are photo electronic detector uses a state of the art optical sensing chamber. Smoke detectors with sounder and relay option.

Throughout the i3 series installation is simple with its installer friendly base and plug in design.
