PRODUCT DETAILS
The Ajax EN54 FireProtect (Heat/Sounder) is a wireless smoke detector designed to deliver fast, reliable fire detection and audible warning in compliance with the EN54 European fire safety standard. Compact and stylish, it integrates seamlessly into the Ajax wireless ecosystem to provide dependable protection for both residential and commercial properties.
Equipped with Two built-in thermistors and an 85 dB sounder, the FireProtect (Heat/Sounder) quickly identifies the presence of smoke particles, triggering an immediate alarm with 32 selectable tones. Audible and visual alerts ensure occupants are notified instantly, while the device also sends real-time alerts to connected smartphones via the Ajax app and to monitoring stations when required.

This wireless series includes addressable point smoke and heat detectors, some of them combined with built-in fire alarm sounders. Each detector provides best-in-class detection accuracy thanks to Ajax's patented smoke chamber with a dual-spectrum optical sensor and two accurate thermistors. With built-in communicators, long battery life, and stable radio communication, the devices are ready for different-scale projects. No need to open the enclosure or run cables — installation and configuration take just minutes via Ajax apps. Early service notifications and automated maintenance reports via Ajax PRO Desktop ensure the system stays easy to support for years.
