4 Wire Smoke Detector With Relay

Smoke detectors with sounder and relay option.

4 wire smoke detector with relay.

System sensor is a global manufacturer of fire and life safety devices in smoke detection carbon monoxide detection and notification technology. For that reason an external power relay must be used with a 4 wire smoke. 4 wire smoke heat detector with relay output ft143. The detector is a combined smoke and heat detector with photoelectronic sensor and heat thermistor together.

Throughout the i3 series installation is simple with its installer friendly base and plug in design. Instead the 4 wire smoke detector s reset is sent through the auxiliary power source. 12 24 v non polarized 2 wire. 783863019999 also known as.

Once a 4 wire smoke activates the only way to reset it is to drop power to that device. This detector is designed to provide open area protection and to be used with most security alarm control panel. 4wtrb bk 4wtrb the 4wtr b is a 4 wire photoelectric i3 smoke detector with thermal sensor and form c relay. Two leds on each detector provide local 360 visible alarm indication.

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. 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. When alarmed just like a conventional heat detector pull station or waterflow switch the relay contacts short out the zone wires. 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. The detectors are photo electronic detector uses a state of the art optical sensing chamber. 10 v to 35 v maximum ripple voltage 30 of applied voltage peak to peak. System sensor 4wtr b photoelectric i3 smoke detector 4 wire thermal sensor form c relay upc.

This is provided by the power supervision relay. 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. 4w b products system sensor system sensor.

Two leds on each detector provide local 360 visible alarm indication. Unlike the 2 wire smoke a 4 wire smoke must also supervise the second pair of wires used for supplying power. 4witar b yes 4 wire 50 ma smoke detector specifications electrical specifications operating voltage nominal. Basically to reset a 4 wire smoke detector the auxiliary 24 volt power supply has to turn off and on.

This detector is designed to provide open area protection and to be used with most security alarm control panel.
