Fire Alarm Smoke Detector Connection

In our basic wiring diagram a single or multiple heat and smoke detectors are installed in the home by connecting the live line or hot neutral ground and an interconnected wire to the alarm.

Fire alarm smoke detector connection. A hardwired smoke alarm installation involves wiring one of the smoke detectors closest to the voltage source to a 120 vac breaker in the main electric panel or tapping from a 120 v electrical box wiring it using a 14 2 cable with a black live a white neutral and a ground wire as shown by the diagram in figure 5. Mains powered smoke heat alarms radiolink radiolink and smartlink wireless interconnection. Because technically it is. Smoke detectors and fire alarms are not synonymous.

Follow the specific fire alarm schematic supplied by the smoke detector manufacturer to make connections. All of the smoke detector wiring is connected to the fire alarm zone on the panel and is fully supervised as if it were a single run. Whether you are using a radiolink module ei100mrf or a smartlink module ei3000mrf the alarms require a permanent 230v ac mains supply which can be taken from a local lighting circuit closest to the individual alarm provided a permanent feed is available. A smoke detector wiring diagram is normally included with every detector and will show you how to correctly hook up the device.

A hard wired smoke alarm or carbon monoxide alarm is connected to other detectors throughout your home. While it s a little more expensive than standard smoke detectors this hardwired product has two in one capabilities that make it worth the extra cost. These alarms sound simultaneously on all levels of your home when a single unit detects smoke or gas. For additional details on making wiring connections to smoke detector terminals check out smoke detector circuit basics.

A smoke detector will sense smoke and sound an alarm in the area where there is smoke. This is the basic fire alarm system used in household wiring. A smoke or heat detector can be installed to the existing or new home wiring. There s a significant difference.

All the units are wired to a 120 volt household electrical circuit and each have a battery backup. Of all the tragedies involving a home fire many went undetected due to a failing smoke detector or fire alarm. For instance the first alert smoke detector and carbon monoxide detector alarm is a top rated product that will alert you to both fire and co. The extra wire in these cables allows the smoke detectors to talk to one another so that all detectors will sound the alarm when any of them detect smoke or fire.

From the first smoke detector box location run 3 wire cable with ground to each subsequent smoke detector.
