A confident final check before the cart.

Ajax VHF Bridge Jeweller — an integration module that connects legacy third-party VHF wireless transmitters to your Ajax security system via the Jeweller protocol. The Ajax VHF Bridge allows installers to migrate existing properties from older VHF-based alarm systems to Ajax without replacing every sensor. Third-party VHF transmitters — such as legacy PIR detectors, door contacts, and panic buttons — connect to the VHF Bridge, which then relays their signals to the Ajax Hub as standard Jeweller devices. This protects the customer's existing sensor investment while gaining Ajax's app, cloud monitoring, and management features. Supports multiple VHF transmitters per bridge. White finish, indoor rated.
