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.
