How to Wire an Alarm Siren

Decide the strategic locations where you would like to install multiple alarm sirens throughout your home or business. It's best to install the alarm siren boxes both inside and outside the premises and on all floors. Choose to use wireless alarm siren boxes if the ceilings are too high or power outlets are not near the locations you choose.

Purchase the amount of wireless alarm sirens you need from a reputable hardware and electrical store such as Lowes or Radio Shack. Also purchase a wireless receiver in order to connect the wireless alarm siren(s) to the existing wired system.

Mount the wireless alarm sirens per the instructions that came with them. Usually they come with a set of screws and batteries for the installation process. You will most likely need to use a drill to make holes and a screwdriver to twist the screws in.

Install the wireless receiver to the primary alarm box system per the instructions that come with the device. Add the wireless transmitter ID number for each wireless alarm siren to the receiver so that it can read the signals and make it fully operational. The batteries last three to five years, however the receiver will alert you if a siren's battery needs to be changed.

Test the system with one or two helpers to determine if they are working properly. Make any necessary changes such as volume adjustment and device positioning.
