Ajax FireProtect 2 RB (CO) Wireless Fire & CO Detector, 2×CR123A, 85 dB, Jeweller — 63213.166.BL1
About this product
Ajax FireProtect 2 RB (CO) is a wireless, battery‑powered indoor carbon‑monoxide and fire detector. Designed to operate standalone or as part of an Ajax security system via the Jeweller radio protocol, it uses a chemical CO sensor (service life ~10 years), provides staged CO alarms at recognised exposure thresholds, and features an integrated siren, LED status indication and anti‑tamper protection. RB models use replaceable batteries (2 × CR123A).
- Detects carbon monoxide with a chemical CO sensor and issues alarms at defined exposure thresholds (e.g. >50 ppm / >100 ppm / >300 ppm staged responses).
- Wireless connection to Ajax hub via Jeweller (two‑way encrypted radio) for integration and alarm interconnection.
- Replaceable batteries (2 × CR123A pre‑installed) — multi‑year battery life depending on settings.
- Built‑in siren (~85 dB), LED indicators and tamper protection.
- Interconnected alarm support via hub: one detector alarm can trigger other system alarms.
Applications: ideal for smart home and small commercial installations where wired detection is impractical. Suitable for homeowners, landlords, and installers requiring integration into the Ajax ecosystem.
Compliance & safety: Available in CE/UKCA and UL/ULC variants — confirm certification for your market before purchase. Install according to local regulations and the device manual. Regularly test detectors, replace batteries as recommended, do not paint or obstruct the sensor, and replace the device or CO sensor at end of service life.
