Operating principle

EN54 I/O Module (2X2) Jeweller is designed to integrate up to 4 third-party wired devices into an Ajax system. The module receives state data from two input devices and controls two output devices with relays with potential-free dry contacts.

The module is powered by pre-installed batteries and does not require an external power supply. EN54 I/O Module (2X2) Jeweller monitors its operational state and informs the system of faults if any occur.

Inputs

With EN54 I/O Module (2X2) Jeweller, it is possible to integrate third-party input devices into an Ajax system. These include manual call points (conventional), sprinkler flow switches, magnetic door contacts, beam smoke detectors, elevator control panels, fan or HVAC control relays, and others.

To connect input devices, use the terminals:

• Input 1 — input terminals for connecting the first wired device.
• Shield — common input for connecting the shield of the cables that connect third-party wired devices.
• Input 2 — input terminals for connecting the second wired device.

Note that EN54 I/O Module (2X2) Jeweller can not supply power to the connected devices. If necessary, provide the power supply to such devices according to their manufacturer’s requirements.

Connection types of wired input devices:

• Without EOL
• EOL
• 2EOL
• 3EOL

In an Ajax app, you can configure the event type and default state (normally open or normally closed) for each sensor of the wired input, as well as the resistance values if an EOL connection is used. This allows you to connect any detector with potential-free dry contacts to the module.

The selected event type determines the text of alarm notifications and events of the connected device, as well as event codes transmitted to the monitoring software.

Event types of wired input devices

Event type	Icon	Meaning
Fire alarm		Alarm in case the device detects a fire.
Device fault		Event caused by the device fault.
Tamper fault		Fault in case the device tamper button is triggered.
Evacuation		Evacuation signal in case of fire hazard.
Custom		User-defined event. Custom events are not sent to the monitoring software.
Auxiliary alarm		Notification of the need for medical or other urgent help.
Panic button		Urgent notification of a threat to personal or property safety.
Gas alarm		Notification of a potential gas leak.
Leakage		Leakage notification to minimize potential property damage.

Outputs

With EN54 I/O Module (2X2) Jeweller, it is possible to control third-party output devices. These include fire door release mechanisms, elevator control systems, fan shutoff or damper control relays, emergency lighting circuits, remote mimic panels, and other life safety and firefighting devices.

Both relays must be installed in the electrical circuit gap to control the power supply of electrical appliances connected to this circuit. The relays are configured and controlled separately.

The operating ranges of each relay output are described in the technical specifications.

To connect to the relays, use the terminals:

• Output 1 — two output terminals of the first relay.
• Output 2 — two output terminals of the second relay.

Note that EN54 I/O Module (2X2) Jeweller can not supply power to the connected devices. If necessary, provide the power supply to such devices according to their manufacturer’s requirements.

When connecting a third-party wired device to the relay output terminals, you can select the terminal state for this device, namely normally closed or normally open, in an Ajax app.

Each output device can be controlled manually via Ajax apps or the CIE touch screen.

Also, the module has the Fail-safe mode feature for outputs. When the mode is enabled, the module automatically activates the connected devices in case of any fault, such as when the module is offline, discharged, or malfunctioning. The devices remain activated until the fault is resolved.

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 module 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.

EN54 I/O Module (2X2) Jeweller can transmit the following events:

1. Module fault.
2. Tamper alarm/recovery.
3. Events and alarms of connected input devices.
4. Loss/recovery of communication between EN54 I/O Module (2X2) Jeweller, connected input devices, and the CIE.
5. Short circuit or damage to the line connecting third-party input devices to EN54 I/O Module (2X2) Jeweller (for EOL connections).

When an alarm is received, the monitoring station operator knows precisely what happened and where. The addressability of Ajax devices allows for sending events to Ajax PRO Desktop or the monitoring software, including the device type, its name, fire zone, virtual room, and location description. 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

Follow your local fire safety regulations when selecting the module installation site.

It is advisable to choose an installation site where EN54 I/O Module (2X2) Jeweller is hidden from prying eyes — for example, in a back room. This will help reduce the likelihood of system sabotage. Note that the device is intended for indoor installation only.

When choosing where to place EN54 I/O Module (2X2) Jeweller, consider the parameters that affect its operation:

• Jeweller signal strength.

Consider the placement recommendations when developing a system project. Only specialists may 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 packages 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. For the device 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 module will operate stably. Consider relocating the module, as adjusting its position even by 8 inches or changing its orientation relative to the CIE can significantly improve the signal strength. If the signal remains poor or unstable after relocation, consider using an Ajax radio signal range extender.

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

Where not to install the module

Preparing for installation

Cable arrangement

When preparing to lay cables, read the electrical and fire safety regulations in your area. Strictly follow these standards and regulations.

Cable specifications for input and output devices

We recommend using fire-resistant cables that comply with the fire safety regulations applicable in your region.

Wires with a conductor cross-sectional area of 0.4–2.5 mm² (21–13 AWG) can be connected to the module terminals.

To check specific cable requirements, refer to the user manual of the device that will be connected to the module.

Cable routing

The EN54 I/O Module (2X2) Jeweller casing allows wires to be routed from the back, side, top, or bottom.

To route the cable from the back, you can use the central hole highlighted in the picture.

To route the cable from the side, top, or bottom, you can drill holes following the recesses on the module casing, considering the size of cable glands. There are two recesses on each side of the module. We recommend using a hole saw for plastic up to Ø20 mm.

Also, consider that the front lid of the module can be rotated 180° during installation.

Preparing cables for connection

Remove the insulating layer and strip the cable with a special insulation stripper. The wire ends inserted into the device terminals must be tinned or crimped with a sleeve. This ensures a reliable connection and protects the conductor from oxidation.

To check specific cable preparation requirements, refer to the user manual of the device that will be connected to EN54 I/O Module (2X2) Jeweller. Follow these requirements to ensure stable operation of the device.
