Build a Smarter, Safer System: A Pro's Guide to Alarm Accessories

A reliable security alarm is more than just a single box on the wall; it's a complete ecosystem of high-quality components all working together to protect a property. To build a system that offers your clients true peace of mind, you need professional-grade alarm accessories that are dependable, compliant, and easy to install.

At SCHNAP, our Alarm Accessories range offers all the gear installers and sparkies need to build, upgrade, or maintain smart and effective alarm systems for any residential or commercial setup.

The Core Components of Your Alarm System

We stock all the essential building blocks for a rock-solid security installation.

  • The Brains (Hubs & Keypads): The central control panel or wireless hub is the core of the system. We stock a range of user-friendly keypads that provide an intuitive interface for arming, disarming, and managing the system.
  • The Eyes & Ears (Sensors): These are the crucial devices that detect intrusion. Our range includes a wide variety of sensors, from standard PIR (Passive Infrared) motion detectors to door and window reed switches, ensuring every potential entry point is covered.
  • The Voice (Sirens): A loud internal siren and an external siren with a strobe light are the number one deterrent for any intruder. We stock a range of high-decibel options to ensure any alarm is impossible to ignore.

Expanding & Powering Your System

Need to add more coverage or ensure your system stays online? We've got you covered.

  • Zone Expanders: Run out of inputs on your main alarm panel? A zone expander module is the simple, cost-effective solution to add more sensors to the system.
  • Power Supplies & Batteries: The reliability of your system depends on clean, consistent power. We stock a range of high-quality power supplies and essential backup batteries to keep the alarm running even if the power goes out.
