Introduction to Ajax FireProtect Plus (Black) — Smoke, CO & Heat
Ajax FireProtect Plus (Black)is a compact, wireless multi‑sensor detector that combines photoelectric smoke detection, temperature sensing (heat and rapid rise) and an integrated carbon monoxide (CO) sensor into a single, easy‑to‑install unit. Designed for indoor use, the device includes an internal ≈85 dB siren, LED status indicator and ships with preinstalled batteries for immediate operation. It can function as a standalone alarm or connect to an Ajax Hub using the Jeweller two‑way encrypted radio protocol for remote alerts, centralised monitoring and integration with third‑party systems via bridges. SKU: 38106.16.BL1. Suggested retail price: 149.00.
Key features at a glance
- All‑in‑one sensing:Photoelectric smoke chamber + temperature sensor + CO sensor.

Detailed description: specifications and benefits
The Ajax FireProtect Plus packs a variety of features and certified sensor thresholds into a slim, 132 × 132 × 31 mm housing weighing about 220 g. Its multi‑sensor approach reduces false alarms while increasing the likelihood of early detection for different types of hazards.
- Smoke sensor:Photoelectric (optical) chamber — excels at detecting smoldering and smoky fires without being overly sensitive to cooking fumes when sited correctly.
- Temperature alarm:Triggers at approximately 60 °C or on a rapid rise condition (+30 °C within 30 minutes as per manual), which helps detect fast‑developing heat events even if smoke hasn’t filled the chamber yet.
- CO alarm thresholds:Levels are aligned with common safety guidance: 30 ppm (≈120+ min), 50 ppm (60–89 min), 100 ppm (10–39 min) and 300 ppm (~3 min) — enabling early warning for dangerous carbon monoxide exposure.
- Battery type:2 × CR2 (main) with CR2032 backup, preinstalled for rapid commissioning.
- Battery life:Up to 4 years typical — minimising maintenance frequency in domestic or small commercial installations.
- Maintenance alerts:The Ajax system issues warnings for required cleaning or battery replacement; the app provides remote testing and configuration to verify device health without climbing ladders.
- Protocol & range:Jeweller two‑way encrypted radio with up to ~1,300 m open‑space range (region dependent) — suitable for many homes and small businesses where cabling is impractical.
- Integration:Works standalone or with Ajax Hubs for remote notifications and central monitoring. Third‑party integrations are possible via ajax uartBridge/ocBridge Plus.
- Siren & indicators:Internal ≈85 dB siren at 3 m and LED for on‑device status; combined outputs improve on‑site awareness in addition to remote alerts.
- Security features:Tamper detection and jamming detection/anti‑fraud features help ensure the unit remains operational and reliable in hostile environments.
Use cases and scenarios where FireProtect Plus excels
The FireProtect Plus is well suited to a range of residential and light commercial environments. Its combination of smoke, heat and CO detection makes it an attractive choice wherever multi‑hazard protection is desirable but wiring or mains connections are impractical.
- Living rooms, bedrooms and hallways benefit from combined smoke and CO protection without the need for separate devices.
- Preinstalled batteries and simple mounting make it ideal for rentals, holiday lets and retrofit projects.
- Spaces with combustion appliances (gas boilers, small heaters) gain CO protection alongside fire detection.
- Wireless connection to an Ajax Hub enables centralised alerts and staff notifications without building rewiring.
- For owners of Ajax systems, adding FireProtect Plus adds CO detection to an existing fire/security architecture with remote alerts, event logs and automation rules.
- Third‑party integrations via uartBridge/ocBridge Plus allow connection to building management or monitoring platforms in hybrid systems.
Comparisons with similar products on the market
Combination detectors are common, but the FireProtect Plus differentiates itself in a few key areas: wireless range and security, integrated CO sensing, and the Ajax ecosystem’s remote‑management capabilities.
- Basic alarms typically detect smoke only and lack CO sensing, tamper/jamming detection or remote notifications. FireProtect Plus adds multi‑hazard coverage and app alerts.
- Standard models are cheaper but do not provide encrypted wireless integration or long‑range radio features.
- Nest Protect offers Wi‑Fi/Bluetooth connectivity and a polished app experience; however, Nest Protect uses different networking approaches and may rely on home Wi‑Fi for remote alerts. FireProtect Plus uses a dedicated two‑way radio (Jeweller) and integrates into professional Ajax hubs and monitoring setups.
- The FireProtect Plus includes specific CO alarm thresholds and features like jamming detection and tamper alerts that are targeted at security‑grade deployments.
- The main difference is the integrated CO sensor in FireProtect Plus. If CO monitoring is a requirement, FireProtect Plus is the clear choice. Otherwise, the standard FireProtect may offer a lower‑cost option for smoke/heat detection alone.
Customer feedback and representative reviews
Publicly available user sentiment for combination detectors like FireProtect Plus tends to highlight ease of installation, fewer false alarms with photoelectric sensing and appreciation for multi‑sensor coverage. Representative themes gathered from buyers of Ajax multi‑sensors and similar devices include:
- "Easy to set up, arrived with batteries installed and paired quickly to our hub — great for renters and retrofit projects."
- "We like having CO detection built in. It gives peace of mind in a property with gas appliances."
- "Long battery life and remote testing via the app removed a lot of maintenance hassle."
Note: these quotes are representative of common user feedback patterns for Ajax combination detectors and similar multi‑sensor products. Actual customer reviews should be consulted on retailer pages for specific user experiences and ratings.
Limitations and regulatory notes
While FireProtect Plus is a versatile and capable detector, it’s important to note it is battery‑powered and may not replace a mains‑powered, interlinked fire alarm system where local regulations require such installations (for example in some commercial buildings or apartment blocks). Always follow the official Ajax installation manual for siting, testing and commissioning and refer to product certification pages for CE/UKCA and region‑specific approvals.
Conclusion: why choose Ajax FireProtect Plus (Black)
The Ajax FireProtect Plus (Black) is a strong option for anyone seeking compact, wireless multi‑hazard protection with professional features. Its combination of photoelectric smoke detection, temperature sensing and integrated CO monitoring offers broad hazard coverage in a single device, while the Jeweller encrypted radio protocol, tamper/jamming detection and app‑based maintenance alerts make it suitable for modern homes and small commercial installations.
Key advantages include preinstalled batteries and long typical battery life (up to 4 years), ≈85 dB internal alarm, comprehensive integration options with Ajax Hubs and third‑party bridges, and a maintenance‑friendly remote monitoring experience. For properties where mains interlinking is not available or desired, and where CO detection is required alongside smoke and heat sensing, FireProtect Plus presents a compelling balance of safety, convenience and security‑oriented features. As always, verify local regulatory requirements and consult the official manual when planning installation.
