Ajax FireProtect 2 RB (Heat) Wireless Heat Detector Jeweller White

The Ajax FireProtect 2 RB (Heat) is a wireless heat detector designed for indoor use, providing reliable fire detection through rate-of-rise and fixed temperature sensing. It operates on the Jeweller radio protocol, ensuring secure and stable communication with Ajax hubs and range extenders. This detector is ideal for environments where smoke detectors may cause false alarms, such as kitchens, garages, and boiler rooms.

Advantages

Wireless installation with up to 10 years battery life, automatic self-testing, and tamper protection against opening and detachment. The detector uses two built-in thermistors to accurately measure temperature changes, triggering an alarm when the temperature rises above 8.5°C per minute or exceeds +64°C. With a loud 85 dB siren and AES-128 encryption, it ensures both safety and security.

Suitable for

• Kitchens and cooking areas
• Garages and workshops
• Boiler rooms and utility spaces
• Any indoor area prone to dust or steam where smoke detectors are unsuitable
