Check the external controller

uartBridge needs a third-party controller implementing its UART protocol. It does not connect to an Ajax hub.

What else needs checking?

Verify the receiver firmware, exact supported detector models and complete host integration before commissioning.

Confirm the regional equipment version for LV; a country name alone does not identify the radio version.

Confirm the 5 V supply, connector, 57,600-baud interface and host software. Maximum 85 devices.

Ajax compatibility reference

Ajax detector data for your own integration.

uartBridge connects supported Ajax wireless detectors to a third-party security or smart-home controller through UART. It supplies detector events and status to the host’s software, which must implement the documented protocol. This receiver is intended for a planned hardware and software integration.

Principle of operation

Wireless detectors to your UART integration

uartBridge receives events and status from supported Ajax detectors and exchanges them with a third-party controller over UART. The host application must implement the documented protocol and decide how each event is handled.

This is a receiver for a third-party controller. It is not an Ajax hub and does not bring third-party wired detectors into an Ajax app.

Plan the receiving interface.

Up to 85 devices over UART

The interface runs at 57,600 baud. The board has a WH-4 four-pin plug and requires the matching HU-4 socket for the wire-to-board connection. The host must handle registration, arming state, detector data and faults through the protocol.

The specified maximum is 85 connected devices. This is an integration module requiring host software, not a USB adapter or a ready-made smart-home app.

Use the supported Ajax wireless devices.

An exact compatibility list

These receivers support the listed legacy Ajax devices. A product sharing the Jeweller name, enclosure or family name is not automatically compatible.

  • MotionProtect Jeweller
  • MotionProtect Plus Jeweller
  • CombiProtect Jeweller
  • DoorProtect Jeweller
  • FireProtect Jeweller
  • FireProtect Plus Jeweller
  • LeaksProtect Jeweller
  • Ajax SpaceControl Jeweller
  • GlassProtect Jeweller

They do not connect to an Ajax hub and do not provide Wings photo verification. Use the exact supported generation; FireProtect 2, MotionCam, Pass and Tag are not in this receiver list.

Check the actual radio link

The specified maximum distance is 2,000 m in open space. Walls, metal, enclosure placement and the detector model affect the usable link. Test radio strength and detection at the installation site.

Two-way Jeweller communication includes encryption, authentication and jamming detection. Choose the correct regional radio version and implement alarm, fault and lost-device handling in the receiving system.

Commission the module with its host.

Power and test the complete integration

Provide the specified 5 V DC supply through the interface and follow the documented connector and protocol requirements. Fit the board securely inside the host enclosure, leaving the antennas suitably positioned for radio reception.

Test registration, arm/disarm commands, alarm delivery, lost-device supervision and jamming reporting in the actual host application. Both the integration code and the installed radio link need verification.

Service benefits & conditions

Eligibility, availability and service terms are confirmed with your quote.

  1. Included installation. Applies to eligible wireless equipment purchases with an agreed total from €6,000 including VAT. The proposal confirms the installation scope and local coverage. Configuration, agreed wireless installation, oversight, tests and training are included. Electrical and plumbing work and monitoring subscriptions are separate. G3 and Superior wireless S-line products do not count towards the €6,000 eligible equipment budget and are not covered by the included-installation offer. Their installation is quoted separately. Fibra and cabling are also quoted separately. Only eligible battery-powered wireless devices, ordinary hubs, ReX and wireless kits contribute. Devices requiring additional power or wired connections (including Relay, WallSwitch, LightSwitch, Socket, Outlet, FireProtect 2 AC and integration modules), WaterStop, Hub BP, video and EN54/Type4 equipment do not count. Accessories, delivery and Care fees do not count either. Hub and ReX connection to an existing socket is included; new power supplies, cabling, electrical and plumbing work are arranged separately. Included installation is available at one property in Latvia, Lithuania or Estonia and includes preparation and the visit. Below €6,000 of eligible equipment, it is a paid option at checkout. Your basket shows the complete service price, including VAT; scope and the visit date are agreed before installation.
  2. Free EU delivery. Free equipment delivery within the EU. Stock, dispatch and destination service are confirmed before accepting your order. Where a three-business-day delivery service is confirmed, it runs from dispatch. Split shipments and made-to-order products may follow separate agreed schedules. Delivery agreed as free does not acquire an undisclosed surcharge. Installation is scheduled separately.
  3. Payments, finance and leasing. Monthly payments and leasing with an upgrade option require a separate agreement, subject to finance-provider approval, credit eligibility and country availability. The provider, deposit, APR, fees, total payable, duration, ownership and return or upgrade conditions are explained before any agreement. An enquiry or saved preference does not activate credit.
  4. Personal setup. One scheduled remote first-setup session for eligible equipment purchased from SAFE365. Equipment must be ready for configuration. Session scope, language and availability are confirmed when booked; physical installation and cabling are separate unless included in your project.
  5. Care 24. Included remote support and agreed remote maintenance for the first 24 months for eligible SAFE365 purchases. The start date, support hours, access permissions and covered tasks are confirmed with your order. On-site work, 24/7 alarm monitoring and extended hardware cover are not included unless separately agreed. Statutory rights and the manufacturer's applicable warranty are unaffected.
  6. Local installation. Partner coverage varies by country and postcode. A named partner, the work scope, responsibility and price are confirmed in writing before commitment. Local installation is included only for an eligible agreed package; otherwise it is quoted separately.
  7. Included system preparation. Preparation is included from €3,000 of eligible equipment, including VAT after discounts. The order must include an eligible hub. We configure, label and check the marked wireless devices and provide individual instructions. Below the threshold, preparation is a paid option at checkout; your basket calculates the price. The same equipment eligibility rules as for included installation apply. Service charges do not count towards either threshold.
