Ajax FireProtect Plus Multi‑Sensor Detector features

Ajax FireProtect+ (White) with Advanced Fire Detection Features

Ajax FireProtect Plus Wireless Smoke, Heat & CO Detector, 85 dB, 38107.16.WH1

Introduction — What the Ajax FireProtect Plus brings to your safety setup

Ajax FireProtect Plusis a wireless indoor multi‑sensor detector that combines a photoelectric smoke chamber, rapid‑rise heat detection and a carbon‑monoxide (CO) sensor in a single compact unit. Designed to work as part of Ajax security systems via the Jeweller two‑way encrypted radio protocol — or as an independent local siren — it aims to reduce false alarms, speed detection of real incidents and simplify installation and maintenance with pre‑installed batteries and remote management tools.

Key features at a glance

  • Multi‑sensor detection: Photoelectric smoke sensor + temperature (rapid‑rise) + CO sensor.
  • Built‑in alerting: 85 dB siren with LED indication and local silence capability.
  • False‑alarm mitigation: HazeFlow logic in the smoke chamber to filter nuisance triggers.
  • Wireless integration: Jeweller two‑way encrypted radio protocol for Ajax hubs and extenders; remote configuration and alerts via Ajax apps.
  • Long battery life & convenience: Pre‑installed batteries (2 x CR2 + CR2032) providing up to ~4 years typical operation.
  • Robust security: Tamper detection, anti‑spoof authentication and jamming detection.

Detailed specifications and benefits

The FireProtect Plus is engineered to satisfy both simple home safety needs and more demanding small business installations. Below are the core specifications and the practical benefits they deliver.

  • Smoke sensor: Photoelectric chamber with HazeFlow false‑alarm filtering. Benefit: photoelectric sensing detects smoldering fires earlier than many ionisation sensors, and HazeFlow reduces nuisance alarms from steam or cooking smoke while maintaining sensitivity to real events.
  • Heat detection: Rapid‑rise detection plus a threshold at approximately +59 °C ±2 °C. Benefit: rapid‑rise sensing detects fast temperature increases (typical of flaming fires) even where smoke patterns might be atypical.
  • CO detection: Multi‑level alarm thresholds (30 / 50 / 100 / 300 ppm time‑based triggers). Benefit: time‑weighted CO thresholds align with health risk guidance so the device not only warns of immediately dangerous concentrations but can alert earlier at lower, prolonged exposures.
  • Batteries: 2 × CR2 main batteries and a CR2032 backup are pre‑installed. Benefit: quick out‑of‑box operation and an estimated life of up to ~4 years under typical conditions reduces maintenance visits.
  • Siren & indicators: Built‑in 85 dB siren (measured at 3 m) with LED status indication and support for local or remote silence. Benefit: loud local alerting for occupants and flexible alarm handling through the Ajax app for remote management.
  • Anti‑sabotage: Tamper detection and anti‑spoof/authentication. Benefit: improved system integrity and fewer false alarms due to tampering or signal spoofing.
  • Protocol: Jeweller two‑way encrypted radio. Benefit: fast, secure communication to Ajax hubs with configurable polling intervals and alarm delivery times (~0.15 s signaling).
  • Range & bandwidth: Up to ~1,300 m in open space (region dependent) and adjustable RF power. Benefit: reliable coverage across many property types; extenders can be used where required.
  • Third‑party integration: Compatible with Ajax hubs and extenders; supports ocBridge Plus / uartBridge for integration with external monitoring or automation systems. Benefit: works in professional alarm setups and can be integrated into broader building management or monitoring setups.
  • Dimensions & weight: 132 × 132 × 31 mm, 220 g — compact ceiling‑mount form factor suitable for most rooms and corridors.
  • Operating conditions: 0 °C to +65 °C, up to 80% non‑condensing humidity; protection class IP40.
  • Warranty: 24 months (manufacturer warranty).

Use cases and scenarios where FireProtect Plus excels

The combination of smoke, heat and CO detection in a single device — plus wireless connectivity and a local siren — makes the FireProtect Plus a versatile choice across a variety of settings:

For homeowners and renters, the device offers broad coverage with fewer units. Install FireProtect Plus in living rooms, hallways outside sleeping areas and near fuel‑burning appliances to detect smoke, rapid temperature rises and dangerous CO. The built‑in siren and mobile alerts mean occupants are warned both locally and remotely.

Small shops, cafés and offices can benefit from the multi‑sensor approach to reduce false alarms while keeping early detection of both smouldering and fast‑burning fires. Wireless installation simplifies placement without the need for hard‑wiring and the device’s compatibility with Ajax hubs enables centralised monitoring.

Properties that are not continuously occupied (holiday lets, storage rooms, workshops) need reliable detection and remote notifications. The FireProtect Plus’s long battery life, tamper alerts and connectivity via Ajax give owners confidence that issues will be noticed promptly.

Where a building already uses Ajax security, FireProtect Plus adds fire and CO coverage without extra cabling. For third‑party integrations, ocBridge Plus / uartBridge lets system integrators incorporate device events into monitoring or automation platforms.

How FireProtect Plus compares with similar products

Multi‑sensor detectors are increasingly common, but differences in detection philosophy, connectivity and maintenance set products apart. Here are the key comparison points to consider.

Photoelectric chambers with intelligent filtering (like HazeFlow) are better at reducing cooking/steam false alarms compared with older ionisation designs. FireProtect Plus’s combination of photoelectric smoke, rapid‑rise heat and CO sensors provides broader detection capability than single‑function detectors and fewer nuisance triggers than simpler photoelectric-only units.

Compared with consumer smart detectors that rely solely on Wi‑Fi, the FireProtect Plus uses a purpose‑built two‑way encrypted radio (Jeweller) designed for alarm systems — offering faster signaling, configurable polling intervals, and jamming detection. For professional installations and monitored systems, this is an advantage over stand‑alone consumer devices.

Many smart detectors trade battery life for constant Wi‑Fi connectivity; FireProtect Plus balances long life (up to ~4 years) because of its efficient radio protocol and lower power consumption. This reduces maintenance frequency, which is important for dispersed installations.

An 85 dB siren measured at 3 m is competitive for local alarming; some dedicated wired fire alarms are louder, but the FireProtect Plus’s built‑in siren is sufficient for typical residential and small commercial rooms and has the advantage of local silence and remote control through the Ajax app.

Customer feedback and reviews

While individual experiences vary by installation and environment, common themes from users of Ajax multi‑sensor devices include:

  • Easy installation and quick setup thanks to pre‑installed batteries and the SmartBracket mounting plate.
  • Reduced nuisance alarms in kitchens and bathrooms due to HazeFlow filtering.
  • Reliable remote notifications and fast alarm delivery when paired with an Ajax hub.
  • App control and testing functions are appreciated by homeowners and property managers for maintenance and monitoring.

These sentiments are representative of aggregate customer impressions rather than individual endorsements. If you require verified testimonials, check retailer pages or installer references for reviews tied to your region and usage scenario.

Conclusion — Who should choose the Ajax FireProtect Plus?

TheAjax FireProtect Plusis a compelling choice for people and organisations that want a compact, low‑maintenance multi‑sensor detector with professional‑grade wireless integration. Its combination of photoelectric smoke sensing, rapid‑rise heat detection and multi‑level CO monitoring covers a wide range of fire and carbon monoxide scenarios while HazeFlow filtering and tamper protections reduce false and malicious alarms.
