Security Accessories – Expanders, Modules & Communicators

Upgrade, expand or repair your alarm system with our range of expanders, communication modules, PCBs and enclosures. This collection is ideal for adding extra zones, enabling IP or 4G reporting, replacing panel boards, and extending outputs for automation and access control.

Not sure which module suits your panel version? Send us your panel model and firmware/version details (or a photo) and we’ll help confirm compatibility.

• Zone expanders (input expanders for adding wired zones)
• Output expansion modules (for sirens, relays, automation and control outputs)
• IP / Ethernet modules and LAN interfaces for remote connectivity
• 4G / 3G / GSM communicators (where supported by the platform)
• Replacement PCBs for alarm panels and expansion boards
• Metal enclosures & mounting boxes for tidy, secure installations
• Service tools such as programmers, unlock keys and interface boards
• Relay modules for specialised control applications (e.g., garage doors)

• Increase zone capacity for larger homes and businesses
• Add IP or cellular communication for monitoring and remote notifications
• Enable push notifications (system and module dependent)
• Expand outputs for automation, access control integration and third-party triggers
• Replace damaged PCBs and restore system reliability
• Future-proof your security system as your site grows

Tip: Always check voltage, bus type (e.g., RS485), and panel compatibility before purchasing.

• Module type needed: zone expander, output expander, IP module, cellular communicator, PCB, enclosure
• Connection method: plug-in, RS485 bus, LAN/Ethernet, wireless platform
• Power requirements: voltage and current draw allowances
• Firmware/version compatibility (important for some IP modules and panels)

If you’re unsure, contact us with your panel details and what you’re trying to achieve (more zones, IP, 4G, replacement PCB, etc.).

Share your system brand/model and your goal (add zones, enable IP/4G, replace a PCB), and we’ll recommend compatible options.
