Alarm Modules

Does your home security need a facelift? An alarm module enables you to add new, advanced features and devices to your current alarm system, thereby creating a safer and more comfortable environment. Communicate wirelessly with your alarm, prevent carbon monoxide poisoning, receive email and text message notifications, and monitor additional zones not accessible with your default configuration. Of course, not all basic home alarm systems can be expanded, and many of these devices are designed for use with specific models, so make sure to review the product descriptions carefully before making a purchase.

A Variety of Modules to Choose From

What kind of module are you looking for? Do you need additional smoke detectors, motion detectors, glass break detectors or carbon monoxide detectors? We offer modules for all of the above, and some power supply modules even allow for multiple sirens and strobe lights. Some of the more popular modules are even used for applications such as controlling lights, appliances, security gates and garage doors.

Alarm Relay Internet Modules

We even offer Internet Connection Modules (ICM), which allow you to control, monitor and communicate with your system via the Internet. In addition, you can find modules which support both 2-way audio VOX and push-to-talk home alarm verification. With the right module, you can turn your simple home security system into an intuitive, 21st-century security powerhouse.

Wired vs Wireless

If you have an expandable alarm system, you should be able to add multiple modules, and HomeSecurityStore.com offers both wired and wireless options to suit every need. Most modules require their own transformer or battery, and some—like the Ademco Honeywell Digital Cellular Communicator for Lynx Plus—require you to have specific services, like AlarmNet. So make sure to read all product descriptions carefully.
