Ajax FireProtect 2 SB (Black) is a wireless multi‑sensor indoor detector providing smoke and rapid heat detection. The SB variant features sealed non‑replaceable batteries with a nominal 10‑year life and is designed to integrate with Ajax hubs via the Jeweller two‑way encrypted radio protocol.

• Multi‑threat detection: dual‑spectrum optical smoke chamber and rapid thermistor heat detection (Class A1R). CO sensing available on CO variants.
• False‑alarm resistance: dust‑ and insect‑protected smoke chamber and algorithmic filtering to reduce nuisance alarms.
• Power: SB sealed lithium batteries — nominal 10‑year life. Low battery notifications via app, LED and audible signals.
• Wireless communication: Jeweller two‑way encrypted telemetry; long open‑space range (up to ~1,700 m / ~5,500 ft depending on region and environment).
• Audible alarm: built‑in 85 dB siren (measured at ~3 m) with synchronous interconnection via hub or direct fallback interconnection between detectors.
• Tamper detection and communication supervision for anti‑spoofing and connectivity monitoring.
• Includes SmartBracket mounting plate and installation kit. Warranty: 24 months.

Safety & compliance: Designed to meet applicable EN/BS fire safety requirements — installers and end users should follow local regulations and the official Ajax user manual for installation, service intervals and end‑of‑life disposal. Do not paint or obstruct the detector. For CO thresholds and alarm profiles consult the device manual; CO sensing is only present in CO variants.
