When low voltage smoke detectors are added to a house. If your smoke detector is tied into your alarm system you might see if your alarm company has someone who can inspect and replace the smoke detectors that are failing. Combined with fire alarm monitoring this gives the best protection for both life and property.

The reason those batteries are there are as a backup. For details on how to do this see connecting 4 wire smoke detectors. Hard wired detectors are also able to run off both power and batteries making them extra secure. Low voltage hardwired smoke detectors are designed to be connected to a home security system s control panel.

The extra run of 4 conductor wire gives us a return path to the panel. Dead air spaces can keep smoke from reaching the alarm. Two wire smokes use just two wires for data and power and must all be ran on the same run. They tend to be close to the corners where ceilings and walls meet.

All of the hardwire alarm systems we sell. Two wire and four wire varieties can be used with any hardwired alarm system. They will not react to smoke and should not be used to replace smoke alarms but as a supplement to a complete smoke alarm system.

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.

Keep the smoke detector four inches from a ceiling wall intersection and out of corners. In the unfortunate event that the alarm failed to go off during an actual emergency check that it s not in a dead air space. They can also detect home wide threats such as carbon monoxide that could. Four wire smokes use separate two wire pairs for power and zone data and can be separated on their own zones.
