124590.280.WH1 | WIRELESS MODULE WITH TWO INPUTS AND TWO OUTPUTS


Ajax

The Ajax EN54 I/O (2X2) Jeweller wireless module, 124590.280.WH1 , in white, enables quick and secure integration of third-party devices into an Ajax fire alarm system, such as emergency lighting, electric locks, or ventilation systems. Equipped with two inputs and two outputs, it supports the Jeweller protocol for stable communication up to 1,700 m, operates on internal batteries for 5 years, and can be configured in minutes via the Ajax app.

Main specifications:

- 2 inputs and 2 outputs configurable via app

- Jeweler radio communication up to 1,700 m

- Compatibility with NC, NO, EOL, 2EOL and 3EOL devices

- Battery life up to 5 years, no external power supply required

- Complies with EN 54-18 and EN 54-25

Further details

✅ Communication :
The module uses the Jeweller radio protocol to transmit data reliably and securely up to 1,700 m in open terrain . Communication with the control panel (CIE) is two-way, supports connection to Ajax repeaters (optional), and adopts intelligent signal management: automatic power adjustment , frequency switching, and immediate detection of connection loss.
✅ Entrances :
The module is equipped with 2 independent inputs , compatible with NC, NO, EOL, 2EOL and 3EOL contacts , for connecting external devices such as detectors, buttons, sensors or emergency controls. Each input allows the selection of custom events and can be configured in minutes via the Ajax app .
✅ Exits :
The 2 galvanically isolated relay outputs can be configured to control third-party devices (e.g., emergency lights, sirens, electric locks, HVAC systems ). Output activation can be automatic in the event of an alarm or managed manually via the Ajax app.
✅ Anti-sabotage protection :
The module is protected by a tamper-resistant case and a dedicated enclosure to protect the board during installation. Cables can be routed top or bottom for a clean installation, while the internal battery offers up to 5 years of battery life , with easy replacement and in-app notifications if the battery is low .
✅ EN54 Standard:
The device fully complies with the EN 54-18 (input/output modules) and EN 54-25 (radio communication) standards . This makes it certified for use in professional fire protection systems in civil, industrial, and public settings, guaranteeing full regulatory reliability .
