Operating Principle

The EN54 FireProtect (VAD) Jeweller is a wireless fire alarm device that activates a visual alert when a fire is detected. The device's LED frame flashes in a temporal pattern (0.5 Hz) as defined by EN 54-23.

The device is powered by pre-installed batteries and does not require an external power supply. It monitors its operational state and informs the system of any faults.

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 the Ajax PRO Desktop app and monitoring stations in various formats, including SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other protocols.

The system with EN54 FireProtect (VAD) Jeweller installed can transmit the following events:

1. VAD hardware fault/recovery.
2. Low battery alarm/recovery.
3. Tamper alarm/recovery.
4. Loss/recovery of communication between EN54 FireProtect (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 monitoring software, including device type, name, fire zone, virtual room, and location description. The list of transmitted parameters may vary depending on the monitoring software and the selected communication protocol.

Note: 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 is up to 3 m on the ceiling and up to 2.4 m on the wall. Consider the visibility of its LED frame when selecting a location, as this affects performance.

Diagram: Two diagrams illustrate installation heights. One shows a device mounted on a ceiling at 3m height, with a range of 8m. Another shows a device mounted on a wall at 2.4m height, with a range of 8.2m.

When selecting a placement for EN54 FireProtect (VAD) Jeweller, consider the following parameters:

• Jeweller signal strength.
• The distance between the device and the CIE.
• Presence of obstacles to radio signal transmission, such as walls, interfloor ceilings, and large objects in the room.

Consider placement recommendations when developing a system project. Only specialists should design and install Ajax systems. A list of recommended partners is available here.

Signal Strength

Signal strength is determined by the number of undelivered or corrupted data packets over a period. The icon in the Devices tab of Ajax apps indicates 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.

If the signal strength is excellent, the device can automatically adjust radio transmission power to reduce power consumption and radio interference.

Important: Run the Jeweller signal strength test before final installation. The test checks signal strength at the device's maximum transmission power. To comply with EN 54 requirements, the signal strength between the device and the CIE must be three bars.

If the test shows one or zero bars, stable operation is not guaranteed. Consider relocating the device, as adjusting its position by even 20 cm or rotating it relative to the CIE can significantly improve signal strength. If the signal remains poor or unstable after relocation, consider using an Ajax radio signal range extender (coming soon).

Refer to the device functionality testing section to learn how to run the Jeweller signal strength test.

What is the Jeweller signal strength test

Where the Device Cannot Be Installed

• Near metal objects or mirrors that cause signal attenuation and screening.
• In places where temperature and humidity levels are outside permissible limits, as this may damage the device.
• In places with low or unstable Jeweller signal strength, which may result in losing connection to the CIE.
• Closer than 1 m to the CIE or radio signal range extender.
