Ajax FireProtect 2 SB Heat & Smoke Detector, Sealed 10‑Year Battery, Jeweller, FIREPROTECT2/SB(WHITE)

Introduction: Ajax FireProtect 2 SB — Heat & Smoke Detection Redesigned

Ajax FireProtect 2 SB (White)is a modern wireless indoor fire detector that combines advanced smoke and heat sensing with robust wireless connectivity and a long-life sealed battery. Designed for use with Ajax security systems, the FireProtect 2 SB brings together a dual-spectrum optical smoke chamber (HazeFlow 2) and A1R-class heat detection to identify both smouldering and fast flaming fires while reducing common false alarms from steam and cooking. The SB variant features a sealed non-replaceable battery intended to last the device’s service life of around 10 years and includes an integrated 85 dB siren for immediate local alerting.

Key Features at a Glance

• Dual-spectrum smoke sensing (HazeFlow 2)— improved discrimination to lower false alarms from steam and vapour.
• A1R heat detection— two thermistors provide high-temperature and rapid-rise alarms.
• Sealed 10-year battery (SB)— non-replaceable, designed for maintenance-free operation during the service life.
• Built-in siren— approximately 85 dB at 3 m for loud local notification.
• Jeweller wireless protocol— encrypted two-way communication, tamper detection, and long radio range.
• Interconnected alarm capability— coordinated alerts via hub and fallback direct inter-detector signalling.

• Warranty:24 months (verify region/dealer policy)

• Reliable detection of multiple fire types:The combination of dual-spectrum optical smoke sensing and A1R heat detection means the device can detect slow, smouldering fires (which emit more particles) and rapid flaming incidents that cause sharp temperature rises. This dual approach reduces the chance that a single sensor type will miss a developing hazard.
• Reduced false alarms:HazeFlow 2 dual‑spectrum optical chamber is tuned to ignore common nuisance triggers such as steam from showers or cooking vapours, helping avoid unnecessary evacuations and desensitisation to alarms.
• Maintenance simplicity:The sealed SB battery is designed to provide a maintenance-free experience for about 10 years — no periodic battery changes for end users. This is especially beneficial in commercial settings and hard-to-reach locations.
• Local and system-wide notification:An integrated 85 dB siren ensures immediate audible warning in the room, while wireless interconnection through the Ajax hub ensures alarms are relayed across the property for coordinated evacuation and monitoring actions.
• Secure and long-range wireless operation:Jeweller protocol offers encrypted two-way communications, tamper alerts, and a substantial open-space radio range that simplifies placement in larger homes or premises.

Use Cases and Ideal Scenarios

The FireProtect 2 SB is suitable for a broad range of residential and light commercial environments. Typical scenarios where this detector excels include:

• Homes and apartments:Especially useful in kitchens near but not directly above cooking surfaces, living rooms, and hallways where both smoke and heat detection improve early warning without excessive false trips from cooking steam.
• Multi-room residential systems:When part of an Ajax security ecosystem, FireProtect 2 SB units can be interconnected via the hub so an alarm in one room triggers all detectors and the system’s professional monitoring if configured.
• Offices and retail premises:The sealed battery reduces maintenance overhead for landlords and facility managers, and wireless installation avoids disruption to tenant spaces.
• Vacation homes and remote properties:Long battery life and robust radio range make the device suitable for locations visited infrequently or where regular maintenance is inconvenient.
• Renovations and retrofit projects:Wireless operation avoids rewiring, making it simple to add reliable fire detection in older buildings where running new cables is costly.

How FireProtect 2 SB Compares with Similar Products

There are several categories of competing detectors: smart home two-sensor units, traditional standalone smoke alarms, and professional wired systems. Here is how the FireProtect 2 SB stacks up against common alternatives.

• Many smart detectors focus on app integration and voice assistant ecosystems; FireProtect 2 SB focuses on security-grade connectivity (Jeweller), encrypted two-way communication and integration within a professional Ajax security setup.
• Some smart models include replaceable batteries or rechargeable power; the SB’s sealed 10-year battery prioritises maintenance-free reliability but requires unit replacement at end of life.
• Dual-spectrum optical sensing and A1R heat class place FireProtect 2 SB on par or better than many consumer models in reducing false alarms and detecting different fire types.

• Wired systems can offer centralised monitoring and interconnectivity but require professional installation; FireProtect 2 SB achieves much of the same functionality wirelessly, reducing installation complexity.
• Basic battery alarms may be cheaper but often have limited sensing capabilities and shorter battery life; FireProtect 2 SB’s dual sensing and long-life sealed battery deliver better coverage and lower lifetime maintenance.

• The key differentiator for FireProtect 2 SB is integration with a monitored security platform via the Jeweller protocol, encrypted communications, and inter-detector fallback signalling — features usually absent in consumer-only sealed units.
• Volume, detection thresholds and sensor technologies are comparable, but FireProtect 2 SB’s combination of HazeFlow 2 and A1R heat detection is tuned to balance sensitivity and nuisance alarm resistance in real-world indoor environments.

Customer Feedback and Reviews

Representative customer feedback for FireProtect 2 SB typically highlights three themes:

• Reliability and peace of mind:Customers appreciate the dual-sensor approach and the integration into Ajax security systems for coordinated alerts and monitoring.
• Low maintenance:The sealed 10-year battery is often praised by property managers and homeowners who prefer not to deal with periodic battery changes.
• Fewer false alarms:Many users report fewer nuisance activations in kitchens and bathrooms compared with older optical-only detectors, attributing this to the HazeFlow 2 chamber.

Example representative comments (anonymised and paraphrased):

• "Installed these across the house — the app integration and the fact I don’t have to change batteries for years is a real bonus."
• "We used to get false alarms when cooking. Since switching to FireProtect 2 SB we’ve had far fewer interruptions."
• "The alarm is loud and the interconnect feature alerted everyone in the building quickly — exactly what you want in an emergency."

Note: These are representative user impressions commonly reported in product listings and forums; availability of reviews may vary by region and seller.

Installation, Compliance and Practical Considerations

FireProtect 2 SB is intended for indoor use (IP20) and should be installed in accordance with local fire and electrical regulations and the Ajax user manual. The device conforms to relevant EN standards; verify regional approvals (UL/ULC or other certificates) if required for a particular installation. Key practical points:

• Do not attempt to open the sealed battery variant — it is designed to be non-serviceable. Replace the unit when the device reaches its end-of-life notice.
• Position detectors in accordance with manufacturer guidance to ensure optimal smoke/heat sensing and radio connectivity with the Ajax hub.
• Confirm the exact model/variant if CO detection is required — some FireProtect 2 variants include CO sensors; the SB Heat + Smoke variant does not necessarily include CO unless specified.
