Operating principle
EN54 FireProtect (Sounder/VAD) Jeweller is a wireless fire alarm device that activates both audible and visual alerts when a fire is detected.
- The sounder emits a high-volume alarm signal (up to 100 dB at a distance of 3.3 ft, depending on the settings) following a temporal pattern compliant with EN 54-3.
- The device’s LED frame, functioning as a VAD, flashes in a temporal pattern (0.5 Hz) defined by EN 54-23.
Audible and visual alerts are synchronized to ensure simultaneous activation. The device is powered by pre-installed batteries and does not require an external power supply. EN54 FireProtect (Sounder/VAD) Jeweller monitors its operational state and informs the system of faults if any occur.
Jeweller data transfer protocols
Jeweller is a wireless data transfer protocol that provides fast and reliable two-way communication between the CIE and devices. The device uses Jeweller to transmit commands, alarms, and events.
Sending events to the monitoring station
An Ajax system can transmit alarms to both the Ajax PRO Desktop app and the monitoring station in the formats of SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other protocols.
The system with EN54 FireProtect (Sounder/VAD) Jeweller installed can transmit the following events:
- Sounder hardware fault/recovery.
- VAD hardware fault/recovery.
- Low battery alarm/recovery.
- Tamper alarm/recovery.
- Loss/recovery of communication between EN54 FireProtect (Sounder/VAD) Jeweller and the CIE.
When an alarm is received, the operator at the monitoring station knows precisely what happened and where. The addressability of Ajax devices allows sending events to Ajax PRO Desktop or the monitoring software, including the device type, its name, fire zone, virtual room, and location description. Please note that the list of transmitted parameters may vary depending on the monitoring software and the selected communication protocol for the monitoring station.
You can find the device ID and zone number in the device states.
Selecting the installation site
The device is intended for outdoor and indoor installation. The recommended installation height of the device is up to 9.8 ft on the ceiling and up to 7.8 ft on the wall. When selecting a proper location, consider the sounder’s audibility and the visibility of its LED frame, as these determine the device’s performance.
When selecting where to place EN54 FireProtect (Sounder/VAD) Jeweller, consider the parameters that affect its operation:
- Jeweller signal strength;
- the distance between the device and the CIE;
- presence of obstacles to radio signal and sound transmission, such as walls, interfloor ceilings, and large objects in the room.
Consider the placement recommendations when developing a system project. Only specialists must design and install Ajax systems. A list of recommended partners is available here.
Signal strength
The signal strength is determined by the number of undelivered or corrupted data packets over a certain period of time. The icon 
in the Devices 
tab in Ajax apps indicates the signal strength:
- three bars — excellent signal strength;
- two bars — good signal strength;
- one bar — low signal strength, stable operation is not guaranteed;
- crossed-out icon — no signal.
Note that if the signal strength is excellent, the device can automatically adjust the radio transmission power to reduce power consumption and radio interference.
Run the Jeweller signal strength test before final installation. The test checks the signal strength at the device’s maximum transmission power. To comply with the EN 54 requirements, the signal strength between the device and the CIE must be three bars.
If the test shows the signal strength of one or zero bars, we do not guarantee the device will operate stably. Consider relocating it, as adjusting its position even by 8 inches or rotating it relative to the CIE can significantly improve the signal strength. If the signal remains poor or unstable after relocation, consider using a radio signal range extender (coming soon).
Refer to the Device functionality testing section to learn how to run the Jeweller signal strength test.
Where not to install the device
- In places where the acoustic signal may be attenuated (inside furniture, behind thick curtains, etc.).
- Near any metal objects or mirrors that cause signal attenuation and screening of the signal.
- In places where temperature and humidity levels are outside the permissible limits. This may damage the device.
- In places with low or unstable Jeweller signal strength. This may result in losing connection to the CIE.
- Closer than 3 ft to the CIE or radio signal range extender.
Installation
Before installing EN54 FireProtect (Sounder/VAD) Jeweller, ensure that you have selected the optimal location that complies with the requirements of this manual.
Only a professional must install this device.
To install the device:
- Remove the SmartBracket mounting panel from the device. To remove the panel, turn it counterclockwise.
- Secure the SmartBracket panel to a surface using double-sided adhesive tape or other temporary fasteners. The ↑↑ sign on SmartBracket is for informational purposes only. It can help you align the device properly.
Use double-sided adhesive tape for temporary fixation only. The device secured by the adhesive tape can detach from the surface at any time, which may result in damage if it falls.

- Place the device on the SmartBracket mounting panel.
- Adjust the position of the device if necessary. The SmartBracket mounting panel allows the detector to be rotated up to 90°.
Adding to the system
The CIE and the device must operate at the same radio frequency; otherwise, they are incompatible. The radio frequency range of the device may vary based on the region. We recommend purchasing and using Ajax devices in the same region. You can verify the range of operating radio frequencies with the technical support service.
Before adding the module
- Install an Ajax app.
- Log in to your account or create a new one.
- Select a space or create a new one.
- Add at least one virtual room.
- Add a compatible CIE to the space. Ensure the CIE is switched on and has internet access via Ethernet, Wi-Fi, and/or mobile network.
- Check the states in the Ajax app to ensure the space is disarmed and the CIE is not starting an update.
Only a PRO or a space admin with the rights to configure the system may add the device to the CIE.
Adding the device to the CIE
- Open an Ajax app. Select a space to which you want to add the device.
- Go to the Devices tab and select Add device.
- Scan the QR code or enter the device ID manually. A QR code with the ID is placed on the device under the SmartBracket mounting panel. Also, it is duplicated on the device packaging.
