The Ajax vhfBridge White is a transponder that provides a hub with an additional channel to communicate with a monitoring station. The Ajax vhfBridge is a module for connecting Ajax security systems to third-party VHF transmitters/armed response radio transmitters.
The vhfBridge enables the use of Ajax systems in areas with an unstable or no Internet connection, such as nature reserves, mountainous, and desert regions. Alarms and events of the system are transmitted via VHF radio waves over a vast distance. vhfBridge can be used as a primary or a backup communication channel.
The Ajax vhfBridge is compatible with Hub 2, Hub Plus, Hub 2 Plus, Hub Hybrid, ReX and ReX 2. vhfBridge does not work with Hub, ocBridge Plus, uartBridge and third-party security control panels.
Product Code: 25353.92.WH1
Elaborate autonomy – up to 75 hours battery backup
You can add a 7Ah/7.2Ah and 8Ah backup battery inside a vhfBridge casing which can also power up the armed response radio transmitter. In the event of power failures, the vhfBridge and AR Radio Transmitter will continue operating for up to 75 hours.
FEATURES OF THE AJAX vhfBRIDGE:
- Communication range of up to 1,800 meters in a line of sight
- Alarm transmission within 0.15 seconds
- Powered by a 100–240 VAC mains supply and can operate on a 12 V⎓ battery backup (battery not included)
- Place for a 7ah/7.2ah and 8ah backup battery
- Perforated areas in the casing for cable management
- 8 adjustable positive/negative trip outputs for sending events to a VHF transmitter
- Tamper detecting when trying to open or remove unit from the surface
- Up to 75 hours of autonomous operation
- Uncompromised security of communication
- Hassle-free installation

What Our Customers Say
I was very suspicious because of the low prices across all of their products, but they definitely proved me wrong — 2 days delivery time from JHB to a rural town. Definitely worth buying at this store!
What a pleasure to do business with Steve and his team at IOTrend! Fast and friendly service. They keep you informed and respond quickly. I have dealt with them several times and they have consistently provided excellent service.
They had the items I wanted in stock and I was able to collect within an hour of ordering online. Reasonably priced and efficient service.
IOTrend is top notch. Service is first world. Steve went the extra mile with my delivery turnaround time and was very helpful with advice on the energizer. Pricing very competitive. Highly recommend this company for your next purchase.
I was browsing on Sunday for better prices and found the items on IOTrend much cheaper. There is a WhatsApp service on the website — although it was a Sunday, Kobus answered the message. Excellent service.
After-sales service 10/10. Called for assistance — the driver collected the controller board the next morning and delivered it back by midday. Walked me through additional troubleshooting with calls and pictures. Gate motor back in service.
I needed a lithium battery urgently and contacted Devon at IOTrend. We closed the sale by 16:00 and I had it delivered to my home by 16:30. Outstanding.
Fantastic service. After receiving a faulty product (manufacturing issue) I had a replacement within 2 days. I stay in a rural area and they made every effort to help me get this resolved. Also the best prices everywhere I have compared so far!
