AJAX MultiTransmitter Extra Hardwired Zones Up to 18 (Black & White)

AJAX MultiTransmitter with Up to 18 Extra Hardwired Zones, Black and White

The AJAX MultiTransmitter in black and white adds extra hardwired zones to an AJAX alarm system, letting you connect traditional wired detectors and contacts alongside the wireless devices of the AJAX range. It is a practical way to bring existing wiring into a modern system without replacing every sensor.

Each unit provides up to 18 hardwired zones, so a single module can cover a good number of doors, windows and other wired inputs. The black and white finish is chosen to suit the colour scheme of many homes and offices, where a discreet device is preferred.

Wired zones are useful when a site already has cabling in place, for example in older buildings, extensions or commercial premises where running new cables would be disruptive or costly. The MultiTransmitter lets you keep those investments and still manage everything from one AJAX system and app.

Typical uses include expanding a home alarm to additional rooms, adding perimeter contacts to a shop or office, and combining wired and wireless protection so that every entry point is covered. Installers can plan zone allocation to match the layout of the premises.

Because the supplier information is brief, check the included items and compatibility with your current AJAX hub before ordering. Following the installation guidance supplied with the product helps ensure the zones are wired and configured correctly.

AJAX MultiTransmitter, Extra Hardwired Zones Up to 18, Black and White

AJAX MultiTransmitter Extra Hardwired Zones Up to 18 (Black & White)

The AJAX MultiTransmitter is a module for extending an AJAX alarm system with hardwired zones. Where a wireless system relies only on radio devices, this unit gives you a way to connect wired detectors, door and window contacts and other conventional inputs, so that existing cabling can be part of a single, unified security setup. The black and white version is the colour option for buyers who want the device to blend in with light or neutral interiors.

Why hardwired zones matter

Many buildings already have cables run to doors, windows, loading bays or perimeter points. Replacing all of that with new wireless sensors can be expensive and disruptive. Adding hardwired zones means the existing wiring can continue to do its job, while the rest of the system is managed through the AJAX hub and its app. This mix of wired and wireless protection is useful in older properties, extensions, shops, offices and other sites where a full rewire is not practical.

Key features and specifications

  • Adds extra hardwired zones to an AJAX alarm system
  • Supports up to 18 hardwired zones per unit
  • Black and white colour finish
  • Designed to work alongside AJAX wireless devices such as sensors, keypads and panic buttons
  • Part of the AJAX range, managed from the same hub and app

The number of zones gives planners flexibility. A single module can cover a group of rooms or an entire small premises, and the zones can be allocated to match the layout of the building. Check the supplied documentation for the exact wiring method, power requirements and any accessories needed for your installation.

Typical uses

Home owners often use a module like this to bring older wired contacts into a newer alarm system without changing every detector. Small businesses can use it to cover back doors, stock rooms, tills or fire exits that already have cables in place. Property managers may use it across several units, where a common system makes monitoring and reporting simpler. Installers can also use the device to build a mixed system that suits a client who wants to keep some wiring and add new wireless devices where cabling is difficult.

Planning an installation

Before ordering, it is worth making a list of every wired contact and detector you want to connect. Count the number of inputs, note their locations and check the cable routes back to the planned mounting position of the module. This helps you confirm that up to 18 zones will be enough and that the layout is practical. Confirm compatibility with your current AJAX hub and any other AJAX devices in the system, as well as the software version needed for full functionality.

Care and setup

Keep the module in a dry, protected location, away from direct weather and excess heat, and secure the cabling so that it cannot be damaged or disconnected easily. Follow the installation and test procedures in the included guidance, and run a test of every zone after fitting to confirm that each contact is reported correctly. Regular checks of the wiring and connections will help keep the system reliable over time.

The AJAX MultiTransmitter in black and white is a sensible choice for anyone who wants to extend a modern alarm system with the wiring they already have. It brings wired and wireless security together under one system, giving flexibility for homes, offices and commercial premises alike.
