- Instant notifications.
- Remote control and configuration in Ajax apps.
- Frequency bands : 866.0–866.5 MHz / 868.0–868.6 MHz / 868.7–869.2 MHz / 905.0–926.5 MHz / 915.85–926.5 MHz / 921.0–922.0 MHz
- Maximum effective radiated power (ERP) : up to 20 mW / Automatic power control to reduce power consumption and radio interference.
- Radio signal modulation : GFSK
- Radio communication range : up to 1,700 m / Between the device and control and indicating equipment (CIE) or a range extender in an open space.
- 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
