Types of Alarm System Wiring. Keypads and most auxiliary devices use regular 4-conductor, 22-gauge alarm wiring. Wiring for sirens and power runs is 4-conductor fire wire, which can also be used for smoke detectors.

Fire Alarm Wiring. The home alarm wiring listed above would cover all you need for burglary protection. I highly recommend that you consider adding at least some additional wiring for fire protection. This should include: Smoke detectors Carbon monoxide detectors Heat detectors Waterflow alarm, if home is sprinklered

For more details on wiring smoke detectors, see: Smoke Detector Circuit Basics Connecting 2 wire Smoke Detectors Connecting 4 wire Smoke Detectors. Zones 2-8, Standard Burglary Zones Looking at the wiring diagram, zones 1 & 2 each have dedicated terminals for the “Hi” (+) and “Lo” (-) sides of their loops. Zones 3 through 8 share their ...

As with all alarm system wiring, both solid and stranded types are acceptable. Two wires, usually color-coded red and black are used for 12-volts DC power from the main alarm panel. The other 2 wires, green and yellow (or white) are used for the burglar alarm loop.

For wiring at the main panel, see Smoke Alarm Circuit Troubleshooting. For wiring at the smoke detectors themselves, see Troubleshooting Smoke Alarm Wiring. For details on connecting smoke detectors and other devices to a typical alarm panel, see Ademco Vista 20P Wiring Diagram.

Burglar Alarm Wiring for Securing Doors. Burglar alarm wiring connects the main panel to every device in a hardwired home security system. Burglar alarm companies can install wiring during construction, or after a home has been built. Or, if you’re the hands-on type, hardwired DIY security systems are available.

How to Troubleshoot Alarm Panel Wiring Finding and Fixing Intermittently Bad or Falsing Zones. Troubleshooting alarm panel wiring is probably at its most difficult when dealing with an intermittently open zone. A zone like this will usually set …

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! (Because, technically, it is ). For additional details on making wiring connections to smoke detector terminals, check out Smoke Detector Circuit Basics.

Follow the specific fire alarm schematic supplied by the smoke detector manufacturer to make connections. A smoke detector wiring diagram is normally included with every detector, and will show you how to correctly hook up the device. Be sure to leave at least one copy of this paperwork in the main alarm panel, for future reference.

Combined with fire alarm monitoring, this gives the best protection for both life and property. Wiring for low voltage smoke detectors is often pre-wired along with alarm system keypads, hardwire contacts, and motion sensors. When low-voltage smoke detectors are added to a house, the 110-volt units should not be removed. Even if the two units ...
