Product details
The FireProtect 2 SB from Ajax is an advanced wireless smoke detector that integrates both smoke and heat sensors for indoor use. This detector utilizes an optical dual-spectrum sensor combined with the HazeFlow algorithm to optimize smoke detection and minimize false alarms caused by steam or water vapor. An alarm is triggered when the temperature rises by approximately 10 °C within a minute or exceeds 64 °C. The FireProtect 2 SB is part of the Ajax System and supports interconnected fire alarm signals, enabling comprehensive safety monitoring. Wireless communication is conducted via the Jeweller protocol, which offers a range of up to 1700 m in open fields. With a built-in siren of 85 dB and an LED status indicator, the detector ensures effective alerting. Pairing and configuration are easily done through the Ajax Hub using a QR code, simplifying installation and use.
