Upgrading a security system doesn’t always mean starting from scratch.
Most wired detectors like the PIRs, beams, flood or gas sensors still work perfectly fine. The problem isn’t reliability; it’s compatibility.
That’s exactly what the Ajax Transmitter and Ajax MultiTransmitter were made for.
Two clever little modules that take wired detectors and bring them into the world of Ajax smart security with wireless communication, instant alerts and encrypted control.
No drama. No waste.
Keep the Good Gear. Add the Ajax Brains.
We’ve all had that moment on site… staring at a perfectly good sensor and thinking,
“If only I could add this to Ajax.” And I’m sure you are all going “Yes, that was me”.
Good news! you can.
With Transmitter or MultiTransmitter, those reliable detectors you already trust don’t have to go anywhere. They can become part of a fully connected Ajax system that brings monitoring and smart features right into the mix.
Why Replace What Already Works? Upgrade It with Ajax.
Let’s be honest, most older detectors are tough as nails. They do the job. The only problem? They don’t speak the same language as modern systems.
And again, that’s where Ajax stepped in.
The Transmitter modules act as a bridge, connecting devices that use normally closed (NC) or normally open (NO) contacts straight into the Ajax hub.
Old-school reliability meets new-school tech… and they get along perfectly.
Ajax Transmitter
Small, Smart and Straightforward
If you only need to bring one detector online, the Ajax Transmitter is the easy win.
It’s compact, battery-powered and fits neatly inside most housings.
Wire your contact, pair it with the hub and that’s it. Done!
You’ll get:
- Full event reporting and tamper protection
- Encrypted Jeweller communication back to the hub
- A solid 1,600 m range (open air)
Ajax MultiTransmitter
The Workhorse for Bigger Jobs
When you’re upgrading a full wired system… think schools, warehouses or commercial spaces, this is the one you reach for.
The Ajax MultiTransmitter was built for exactly that kind of work. It supports up to 18 zones, each assigned its own event type: Intrusion, Fire, Gas, or Auxiliary. That means both the Ajax app and the monitoring centre know exactly what’s happening No guessing which zone has tripped.
Ajax designed it to make life easier for installers. It supports NC, NO, and even EOL / 2EOL / 3EOL wiring, so you can keep existing cabling and detectors instead of pulling walls apart.
It’s mains powered, with a backup battery that lasts up to four days if the site loses power, and supplies 10.5–15 V DC to power your wired sensors.
Each input can run up to 400 m of cable, with a radio range of 2,000 m (open air).
Need more coverage? Add a few ReX range extenders, and you’re looking at tens of square kilometres.
As Ajax puts it, MultiTransmitter “turns the renovation of a wired alarm into a complete upgrade of the entire security experience.”
And it really does… it’s the difference between “making do” and making the system genuinely smart.

Smart Control Beyond Security
Once you’ve upgraded your wired detectors, you can take things a step further.
Ajax isn’t just about alarms… it also lets you control third-party devices like electric fences, garage doors, lights or irrigation systems using Ajax Relays or smart plug sockets.
You can create smart little automations, like turning on lights when an alarm goes off, closing the gate when you arm the system, or running devices on a schedule.
Everything runs from one app, so your security and everyday control live side by side.
