This will cause theĪlarm panel to generate a trouble condition with beeping keypads,Īlerting the occupants of a problem. Its normally closedĬontacts will open, breaking the detection loop. If the red or black wire is cut, pulled loose, or otherwiseĭamaged, the relay will no longer get power. ThisĬompletes the blue/brown pair detection loop, and all’s well with the Of wires, it holds the output contacts in the closed position. This is provided by the powerĪs long as the relay’s coil gets power from the red & black pair Second pair of wires used for supplying power. Unlike the 2-wire smoke, a 4-wire smoke must also supervise the “seen”, electrically, back at the main alarm panel, and verifies that Notice that the blue & brown pair of wires has the sameĮnd-of-line resistor (EOLR) hookup as the 2-wire smoke. Just assign each color to a function, and use that when making each connection. The actual color of each wire doesn't matter, as long as you connect them the same way at each end. The wire you have may use a different color scheme for the individual conductors than this. If you need to hook up more than one wire to a single fire alarm zone, see how it's done at Smoke Detector Wiring - Connecting Multiple Runs.

For details on how to hook up 2-wire units, see This page shows how to connect single runs of 4-wire smoke detectors. Still other panels are compatible with both. Some alarm panels can use only 2-wire smoke detectors, while others can only use the 4-wire type. Not all alarm panels are compatible with smoke detectors, but most newer ones are. Having one installed, adding smoke detectors is a smart way to get more Whether you’re designing your own DIY home alarm system or If your system is monitored by a central station, you'll probablyĪlso qualify for a larger discount on your homeowners insurance rate. Security system is a good way to increase your safety and security. The wireless option is easier but more expensive, which can be achieved either by choosing an alarm with this feature built-in or using additional wireless bases.Connecting 4 Wire Smoke Detectors Adding Fire Protection to Home Alarm SystemsĪdding either 2- or 4 wire smoke detectors to a standard home Often a cheaper solution, the hardwire interlinked option requires an interconnecting cable that runs through all the alarms, which is best installed by an electrician. There are also two methods of interlinking your smoke and heat alarms, either through a hard-wired link or a wireless radio connection.

The long-life battery versions are often easier to install and feature batteries that ensure the battery cannot be removed – any alarm only powered by a replaceable battery, such as AA and 9V, are not compliant. The mains-powered versions will feature a backup battery which ensures protection even during a power outage but will need installing by a qualified electrician. You can choose to either have a mains-powered alarm or one which is powered by a sealed long-life lithium battery that is tamper-proof. Not every heat and smoke alarm available on the market is compatible with the new Scottish regulations.
