Calculate radio communication range at the facility
Encrypted communication
All stored and transmitted data is protected by block encryption featuring a dynamic key.
Frequency hopping
To prevent radio interference and jamming.
Dangerous temperature detection
Sensitive element
2 × thermistor
According to the EN 54-5 requirements for heat detectors of Class A1, B, and C with rate-of-rise (R) and static (S) response types.
Heat sensor modes
- A1, A1R, A1S
- B, BR, BS
- C, CR, CS
- Fixed temperature
For better detection of fire hazards, depending on the installation site of the device. Can be selected in the device settings. Only the following heat sensor modes are compliant with EN 54 requirements: A1R, A1S, BR, BS, CR, and CS.
Alarm annunciation
Alarm type
acoustic
Sound volume
up to 95 dB at a distance of 1 m
Adjusted by a PRO or user with admin rights in an Ajax app.
Sound pattern
32 tones
Sound synchronization
An audible alarm is automatically synchronized on all devices with a sounder connected to the same CIE.
Alarm annunciation test
An audible alarm check to ensure the fire alarm is clearly audible on the premises.
Installation recommendations
The device is designed for indoor use only.
The SmartBracket mounting panel allows the detector to be rotated up to 90° even after installation.
Sabotage protection
Tamper button
Fault notification when an attempt is made to remove the device from the mounting panel.
Lock for SmartBracket
to secure the device on the SmartBracket mounting panel
When locked, the lock secures the device and prevents it from being removed without a special tool.
Protection against spoofing
device authentication
Connection loss detection
after 36 s
Detection time depends on Jeweller settings.
