Wireless addressable module with two inputs and two outputs for a fire alarm system
Pushing the boundaries of fire safety
EN54 I/O Module (2X2) Jeweller blurs the limits for use cases and compatibility in EN 54-certified Ajax setups. It automates responses to emergencies by integrating gates, door locks, lighting, or alert systems through the module outputs. Its inputs allow complementing the setup with beam smoke detectors, elevator control panels, HVAC systems, or other wired third-party devices to address any fire or life safety scenario. Designed to deliver an Ajax-level experience, the module offers out-of-the-box communication with the CIE, intuitive configuration via Ajax apps, and zero-hassle maintenance.

Key features
Event types
An Ajax app specifies event types for wired device inputs. The selected type determines the text of alarm notifications and events of the connected device, as well as event codes transmitted to the CMS. A PRO or a user with admin rights can configure the event type in an Ajax app.
Fail-safe mode
If the module is offline, discharged, or has hardware problems, it activates the connected devices automatically.
