Ajax FireProtect 2 RB (Heat) Wireless Heat Detector, White, 63208.168.WH1

Introduction to the Ajax FireProtect 2 RB (Heat)

The Ajax FireProtect 2 RB (Heat) is a compact, ceiling-mounted wireless heat detector designed for indoor residential and light commercial environments. Identified by model FireProtect 2 RB (Heat) and product code 63208.168.WH1, this device focuses on Class A1R heat detection — combining high-temperature threshold sensing and rapid temperature-rise detection to provide reliable heat-only fire alerts where smoke detectors are inappropriate, such as kitchens, attics and plant rooms.

Key features include replaceable CR123A batteries with multi-year life, a built-in 85 dB piezo siren for local alarm signaling, two-way encrypted Ajax Jeweller radio communications for seamless integration with Ajax hubs, and tamper protection. The detector ships with a SmartBracket mounting plate and installation kit, and it is available at a suggested retail price of 89.99 (check local pricing for taxes and shipping).

• Class A1R heat sensingfor both sustained high temperature and rapid temperature rise.
• Replaceable batteries(2 × CR123A preinstalled) giving a typical 5–7 year battery life depending on use and settings.
• Wireless integrationvia Ajax Jeweller two-way encrypted radio with long open-space range and robust interconnect options.
• Local alarmwith an internal piezo siren (~85 dB at 3 m) and multi-colour LED indicators, plus a front button for test and mute.
• Compact, unobtrusive designin white, suitable for ceiling mounting and simple DIY or professional installation.

Detailed description of specifications and benefits

Understanding the technical specifications helps clarify where the FireProtect 2 RB (Heat) performs best and the practical benefits it delivers.

• Detection class:Class A1R — detects high-temperature conditions and rapid temperature rises that indicate a developing fire without relying on smoke sensors.
• High-temperature threshold:Approximately 64 °C (147 °F), noting that manufacturer regional variants can differ; this threshold is suitable for recognizing hazardous heat buildup.
• Rapid-rise detection:Detects a temperature increase greater than 10 °C within one minute, enabling detection of fast-developing heat events such as grease or electrical fires.

• Batteries:2 × CR123A (replaceable, preinstalled) — widely available and easy to change when required.
• Battery life:Typical 5–7 years depending on reporting intervals and alarm activity; long battery life reduces maintenance frequency.
• Power management:Built-in reporting and automatic power control provide timely low-battery alerts to the Ajax hub so users can schedule replacements before device failure.

• Radio protocol:Ajax Jeweller (two-way, GFSK) — provides encrypted communications between detector and Ajax hub for reliable alarm reporting.
• Range:Up to approximately 1,700 m in open space (region dependent) which translates to robust coverage in typical residential or small commercial layouts when combined with a hub and recommended placement.
• Encryption and security:Block encryption with a floating key helps prevent spoofing and ensures the integrity of alarm signals.
• Interconnect:Hub-initiated interconnect (approximately 20 seconds) plus detector-to-detector fallback for local signalling if the hub becomes unreachable.

• Siren:Built-in piezo providing around 85 dB at 3 m — loud enough for most rooms to wake sleeping occupants and prompt an immediate response.
• LED indicators and controls:Multi-colour LEDs indicate power, fault and alarm states; a front button allows for testing and muting nuisance alarms (useful in situations like brief harmless heat spikes).
• Form factor:Approx. 44 × 86 × 86 mm and around 146 g. Ceiling-mount design fits onto the supplied SmartBracket for fast installation. The device is rated IP20 and intended for indoor use only.
• Operating environment:Designed to work between 0 °C and +50 °C and up to 80% relative humidity (non-condensing).

• Included items:FireProtect 2 RB (Heat), SmartBracket mounting plate, mounting kit, 2 × CR123A batteries (preinstalled), and user manual/quick start guide.
• Warranty:24 months (region dependent). Users should also verify CE/UKCA markings and local regulatory compliance for their jurisdiction.

Use cases and scenarios where the FireProtect 2 RB (Heat) excels

Heat-only detectors serve important niche roles where smoke detection is impractical or prone to false alarms. The Ajax FireProtect 2 RB (Heat) excels in several specific situations:

• Smoke detectors often produce nuisance alarms from normal cooking. A heat-only detector can detect dangerous temperature rises from grease or pan fires without reacting to everyday cooking fumes.

• Environments where dust, humidity or intermittent vapours can trigger smoke alarm false positives. A heat detector reliably signals thermal hazards before smoke accumulates.

• Areas with vehicle exhaust, fumes or dust can confuse smoke-based systems. Heat sensing provides focused protection against flaming or overheating components.

• When connected to an Ajax hub, the detector becomes part of a monitored life-safety zone with central dispatching, smartphone alerts and automated interconnect to notify occupants across a site.

How it compares with similar products on the market

Heat-only detectors are produced by many manufacturers and range from basic standalone units to networked smart devices. The Ajax FireProtect 2 RB (Heat) sits in the smart, integrated category and compares favourably in several areas:

• Connectivity:Unlike basic stand-alone heat detectors, the Ajax model offers two-way encrypted radio integration, enabling notifications to smartphone apps and central monitoring stations when paired with an Ajax hub.
• Interconnect capability:Many inexpensive heat detectors only sound locally. FireProtect 2 RB provides hub-initiated interconnect and local detector fallback, improving building-wide notification speed.
• Battery life and replaceability:Devices with sealed non-replaceable batteries require full replacement after battery depletion. The Ajax uses replaceable CR123A cells and typically lasts 5–7 years, balancing maintenance ease with longevity.
• Smart features:The addition of LED status indicators, front-button test/mute and remote reporting offers superior usability compared with non-networked units.
• Price point:At a suggested price of 89.99, the FireProtect 2 RB (Heat) is positioned as an affordable smart detector when compared with fully networked brand-name alternatives, though professional-grade commercial detectors with wired connections may cost more and require specialized installation.

Customer feedback and reviews

Independent user feedback for smart heat detectors typically highlights reliability, ease of installation and peace of mind. For the Ajax FireProtect 2 RB (Heat) specifically, common themes reported by installers and homeowners include:

• Appreciation for long battery life and the convenience of replaceable CR123A cells.
• Positive comments about the clear alarm volume and multi-colour LED status indicators, which make it easy to understand device condition at a glance.
• Favourable notes on wireless integration with Ajax hubs, enabling centralized alerts and automated interconnect that help protect multiple rooms or a whole property.
• Practical praise for the SmartBracket mounting system that simplifies installation and removal for testing or battery changes.

Because product performance can depend on correct placement and environment, some users remind buyers to follow local fire-safety guidance and manufacturer instructions when choosing detector locations.
