FireProtect 2 SB (Heat/Smoke) Detector
A next‑generation wireless fire detector combining dual‑spectrum smoke sensing and A1R‑class heat detection for fast, reliable fire identification. Designed to minimise false alarms, FireProtect 2 SB filters steam, resists dust and insects, and reacts rapidly to temperature spikes and synthetic materials burning.
The sealed 10‑year battery ensures long‑term reliability with no maintenance interruptions. An 85 dB built‑in siren provides immediate local alerting, while interconnected alarms ensure the entire premises responds within seconds.
Engineered to meet EN and BS fire safety standards, FireProtect 2 SB integrates seamlessly with Ajax systems for remote monitoring, automation scenarios, and instant notifications.
Key Features
- Dual detection: smoke and heat
- Dual‑spectrum optical smoke sensor with HazeFlow 2 false‑alarm filtering
- A1R‑class heat detection for rapid response to temperature spikes
- Patented dustproof smoke chamber — no regular cleaning required
- 85 dB built‑in siren for immediate on‑site alerting
- Interconnected alarms: primary (hub‑based) and fallback (detector‑to‑detector)
- Jeweller radio communication up to 1,700 m
- LED indicators for power, faults, and alarms
- Tamper protection and spoofing prevention
- SmartBracket mounting for fast installation
- Sealed long‑life battery (up to 10 years)
System Integration
FireProtect 2 SB integrates tightly with the Ajax ecosystem, enabling:
- Instant alarm delivery to Ajax apps, monitoring stations, and automation rules
- Interconnected fire alarms across all FireProtect 2 detectors
- Scenario-based automation, such as unlocking smart locks or shutting down HVAC
- Visual alarm verification when paired with MotionCam detectors or IP cameras
- Siren activation using indoor or outdoor Ajax sirens
- Remote configuration and diagnostics through Ajax PRO and user apps
The detector pairs with the hub via QR code and supports remote firmware updates, ensuring long-term compatibility and performance.
Reliability & Supervision
FireProtect 2 SB is engineered for dependable operation in demanding environments:
- Regular device polling ensures real-time status visibility
- Automatic self-diagnostics monitor sensor health, battery status, and chamber condition
- Communication failure detection alerts the system within 15 minutes
- Dustproof, insect-resistant smoke chamber maintains long-term accuracy
- LED fault indication highlights contamination, low battery, or end-of-life conditions
- Fallback interconnection ensures alarms propagate even if hub communication is lost
These features ensure the detector remains operational, responsive, and compliant throughout its service life.
