Ajax

The EN54-certified Ajax EN54 FireProtect (Smoke/Sounder) Jeweler, 119919.276.WH1 , offers advanced fire protection thanks to a dual-spectrum optical sensor and built-in siren. It guarantees long battery life, quick, wire-free installation, and wireless communication up to 1,700 m, making it ideal for residential and professional environments.

Main specifications:

- Dual-spectrum optical sensor with anti-false alarm algorithm

- Built-in 85 dB siren with 32 selectable tones

- Battery life up to 5 years with CR123A batteries

- Screwless installation with SmartBracket

- Radio coverage up to 1,700 meters in open field

- Compatible with Ajax app for remote management

Further details

✅ Communication :
The system uses Jeweller technology for reliable radio communications up to 1,700 m in open terrain. Alarm signals are transmitted to the central intercom (CIE) within 3 seconds , ensuring a timely response. The detector can be connected to a repeater (sold separately) to extend coverage. The protocol automatically adjusts power and frequency and detects any connection loss, ensuring communication stability and security.
✅ Smoke Detection :
The detector features a dual-spectrum optical sensor that effectively distinguishes between real smoke and false alarms (such as steam or dust). The patented smoke chamber is protected from dust, insects, and contaminants, requiring no frequent maintenance, and improves accuracy. The HazeFlow 2 algorithm analyzes sensor data to distinguish between smoke and steam, adapting to different environmental conditions .
✅ Alarm announcement:
The device includes a built-in 85 dB siren with 32 selectable tones and a sound audible up to 1 meter away. Alarm synchronization between devices occurs automatically when connected to the same CIE. Notifications can be managed remotely via the Ajax app, with the ability to configure the behavior of the acoustic signal based on the type of event .
✅ Anti-sabotage protection:
 Thanks to the SmartBracket system , installation is simple yet secure: unauthorized removal of the device triggers an alert. The device also monitors battery and connection status. The pre-installed CR123A batteries provide up to 5 years of battery life and can be easily replaced without removing the case .
✅ EN54 Standard:
The FireProtect (Smoke/Sounder) Jeweller is EN54 certified , fully compliant with European directives:
  • EN 54-7: smoke detectors
  • EN 54-3: audible signalling devices
  • Directive 2014/53/EU (RED)
These certifications make it suitable for professional installations in residential, commercial and industrial settings, ensuring legal compliance and high safety standards.
