Fire system project review

Requires EN54 Fire Hub Jeweller, a tested radio or local Ethernet path, and a separately purchased EN54 backup battery. It does not extend a Residence intrusion hub.

What else needs checking?

Check the installed panel, extender and device firmware against the required functions during commissioning.

Match regional radio versions and the requirements of the planned fire system.

Up to five extenders within the panel’s 200-device limit. No extender cascading or automatic device roaming. Ethernet requires the same local network through a router.

Bring the fire system farther into the building.

EN54 Fire ReX Jeweller extends the link between EN54 Fire Hub and its wireless devices. Ethernet provides a route around difficult radio obstacles, while Jeweller and Wings carry events and compatible alarm photographs. Device capacity remains defined by the fire panel.

Extend the route. Keep one fire system.

For EN54 Fire Hub Jeweller

Up to five EN54 Fire ReX extenders can operate with the fire panel. An extender can serve up to 199 connected devices within the panel’s overall limit of 200.

Each extender connects directly to the panel; cascading through another extender is not supported. A device is assigned to one extender and does not automatically roam to another if the link fails. Range extension does not increase system capacity.

A wired route around radio obstacles.

Ethernet takes priority when both wired and radio paths are enabled. It can also be the only backhaul path. Both the extender and panel must use the same network through a router; a direct cable between them is not supported.

Historic buildings

Ethernet can carry the connection back to the fire panel when thick walls interrupt the radio route. Devices still need a tested radio link to the extender.

Make the network part of the installation.

A local network path to the panel

The network must allow broadcast queries and port 4269 traffic between the devices. DHCP and static IP addressing are supported; the installer should verify these requirements without exposing the service to the public internet.

The up-to-1,800 m radio and up-to-35 km² system coverage figures refer to open-space conditions. They do not guarantee coverage inside a building.

A secure link across the site.

Jeweller and Wings

Jeweller carries device events and commands; Wings carries photographs and larger data packets. Two-way communication uses encryption, frequency hopping and retransmission to maintain the link.

The stated range is up to 1,800 m in open space. The connected device, walls and layout limit the real installation; confirm regional radio compatibility and test every link on site.

See the event as well as the alert.

Visual context for a fire alarm

A configured scenario can request photographs from a compatible MotionCam detector when a fire device raises an alarm. These images help authorised users and monitoring staff assess the situation.

Requires a supported detector with the appropriate photo-by-scenario capability, a configured trigger and permission to view the images. It complements the planned fire response.

Match photo expectations to the detector.

Photo size and route both matter

For MotionCam (PhOD) at 320 × 240, the manual lists up to 18 seconds over Wings or 10 seconds over Ethernet. Larger images and other detector models have different times.

The examples assume a three-bar detector link and a panel using Ethernet or 4G. A radio backhaul also needs three bars between the panel and extender. Check the full model-specific table in the manual.

Choose backup for the extender itself.

A separately purchased EN54 battery

EN54 Fire ReX uses the specified mains supply and an EN54 Internal Battery (24h) or (72h). The current technical specification lists up to 50 hours with the 24h pack or 100 hours with the 72h pack, with Ethernet enabled.

The battery names are not the extender’s guaranteed runtime. Confirm the required backup duration, actual load and battery condition for the project. The battery and mains cable are not included; the installation manual specifies a 110–240 V~, 50/60 Hz supply.

Keep the route under supervision.

Checks between the panel and its devices

The panel polls the extender, and the extender polls its assigned devices. Polling is configurable from 12 to 300 seconds, with a 36-second default interval.

A polling interval is not the same as the connection-loss notification time. The published 36-second loss-detection figure depends on settings. When Ethernet remains connected, loss of only Jeweller or only Wings does not itself produce a connection-loss notification.

Keep the installed system current.

OS Malevich

The system runs Ajax OS Malevich and supports firmware updates. Review release availability and the site’s service procedure before updating, then verify the required functions.

An update does not replace commissioning, maintenance or a check of exact device compatibility.

Keep faults and interference visible.

Understand the event

Notifications identify the device and location so an authorised user or monitoring operator can investigate. The connected fire panel also presents faults and alarms locally.

Configure user notification channels and the monitoring connection as part of commissioning.

Respond to radio interference

The system checks the radio link and changes frequency within its operating band when needed. Interference and connection faults are reported for investigation.

Protect communication

Device authentication and encryption protect exchanged data. Keep firmware, access rights and the installation settings under the control of authorised users.

Secure the mounting

Tamper protection reports an attempt to open or remove the device. Secure every required SmartBracket fixing point and keep the supplied release key under controlled access.

Add, position and maintain.

Assign devices deliberately

Add the extender to the fire panel using the Ajax app, then assign devices that have already been added to the panel. Match the regional radio version.

Confirm the exact device compatibility list. Fire ReX is not an extender for a Residence intrusion hub.

Test before final fixing

Choose an indoor vertical mounting position and test Jeweller and Wings links to the panel and the assigned devices. Secure the specified SmartBracket with all fixing points.

Target three bars; follow the EN54 radio survey requirements. IP20, −10 to +40 °C and up to 75% non-condensing humidity. The extender cannot repair a weak link simply by being placed beside the panel.
