Operating principle
EN54 Indicator Jeweller is a wireless remote indicator designed for fire safety systems that comply with EN 54 standards. It is installed near the main EN 54-certified detectors, providing a visual alarm indication with a red light.
The indicator is designed for situations where direct visual contact with the detector is hindered or impossible (e.g., detectors are located behind closed doors or false ceilings). The indicator alerts the user to the activation, greatly simplifying the localization of the source of the alarm.
The device is powered by pre-installed batteries and does not require an external power supply. EN54 Indicator Jeweller monitors its operational state and informs the system of faults if any occur.
Jeweller data transfer protocol
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 Indicator Jeweller installed can transmit the following events:
Device hardware fault/recovery.
Low battery alarm/recovery.
Tamper alarm/recovery.
Loss/recovery of communication between EN54 Indicator Jeweller and the CIE.
The system allows disabling fault indication and notifications of Jeweller connection loss for EN54 devices used in mobile environments, such as fire engines.
How to disable Jeweller connection loss notifications for EN54 devices
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. When selecting a proper location, consider the visibility of its LED frame, as it determines the device’s performance.
Follow your local fire safety regulations when selecting the device installation site.
When selecting where to place EN54 Indicator 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 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 EN 54 requirements, the signal strength between the device and the CIE must be at least two 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.
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 not to install the device
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 Indicator 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.
Add EN54 Indicator Jeweller to the CIE and pair with fire detectors.
Place the device on the SmartBracket mounting panel.
Run the device functionality testing.
Remove the device from the mounting panel.
Attach the SmartBracket panel to the surface using the bundled screws for all fixing points. When using other fasteners, make sure they do not damage or deform the mounting panel.
To additionally secure the device on SmartBracket with the lock, move the locking mechanism to
position. In this case, you will need to insert a special tool into the corresponding hole to remove the mounting panel.
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 55°.
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 device
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 can add the device to the CIE.
Types of accounts and their rights
Adding 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.
Assign a name to the device.
Select a fire zone and a virtual room.
If necessary, specify the device location in the Location field.
Select Add device, and the countdown will begin.
Switch on the device by holding the power button for 3 seconds.
Once added to the CIE, the device will appear in the list of CIE devices in the Ajax app. The update frequency for device states in the list depends on the Jeweller settings and is 36 seconds by default.
If the connection fails, try again in 5 seconds. If the maximum number of devices has already been added to the CIE, you will receive an error notification when you try to add more.
EN54 Indicator Jeweller works with only one CIE. When added to a new CIE, it stops sending events to the old one. After the device is added to a new CIE, it will not be automatically removed from the device list of the old CIE. This must be done through the Ajax app.
Pairing with fire detectors
Once the remote fire alarm indicator is added to the CIE, it must be paired with the required fire alarm detectors so that it can indicate their alarms. Otherwise, the indicator would not notify about any alarms.
EN54 Indicator Jeweller is paired with fire alarm detectors by creating a fire alarm scenario in the system.
The fire alarm scenario that pairs the indicator with the fire alarm detectors counts as one scenario from the CIE’s overall limit of scenarios.
To pair EN54 Indicator Jeweller with the fire alarm detectors in an Ajax app:
Select a space and go to:
Control
→ Settings
→ Scenarios and schedule
Tap Add scenario and select the Fire scenarios (EN-54) type.
Specify:
Name of the scenario.
Triggers. Select devices that detect fire conditions and activate the scenario.
Performers. Select EN54 Indicator Jeweller and, if necessary, other devices that respond to triggers by alerting people or controlling building systems.
Scenario notifications. Set whether to send notifications to system users when scenario is executed.
Tap Save.
Note that performers (e.g., EN54 Indicator Jeweller) can be used only in one fire alarm scenario. If a performer device is assigned to another scenario, the system removes it from the initial scenario.
Functionality testing
