Ajax FireProtect 2 RB (CO) Wireless Carbon Monoxide Detector, Black<\/p>\n
CO (carbon monoxide) detection<\/p>\n
The device triggers according to accumulated CO level:<\/p>\n
> 50 ppm, approximately 0.005%: alarm within up to 90 minutes<\/p>\n
> 100 ppm, approximately 0.01%: alarm within up to 40 minutes<\/p>\n
> 300 ppm, approximately 0.03%: alarm within up to 3 minutes<\/p>\n
If CO drops below 50 ppm within one minute, the alarm stops.<\/p>\n
Sensor lifetime: 10 years, after which the device must be replaced.<\/p>\n
Alarm and connection functions<\/p>\n
Built-in siren volume approximately 85 dB at around 3 m, providing an alarm that can be silenced with the Test\/Mute button.<\/p>\n
Interconnected alarm: when one FireProtect detector in the system detects an alarm, the sirens of all system detectors activate within about 20 seconds, even offline, with a suitable firmware version.<\/p>\n
LED indicators:<\/p>\n
Green: power present, flashes approximately every 56 seconds<\/p>\n
Yellow: fault or battery warning<\/p>\n
Red: alarm due to CO level<\/p>\n
Communication range up to approximately 1700 m in open-field conditions. Works with other Ajax devices and is compatible with ReX and ReX 2.<\/p>\n
Power supply and lifetime<\/p>\n
Powered by 2 \u00d7 CR123A batteries, approximately 1600 mAh.<\/p>\n
Battery life up to 5\u20137 years for the RB version. RB requires special energy-saving settings to be enabled in the hub system.<\/p>\n
Recommended service life and optimal sensitivity are up to 10 years, after which the device should be replaced.<\/p>\n

Why choose the CO-only version?<\/p>\n
If you only need carbon monoxide detection, this is a suitable and compact solution.<\/p>\n
CO sensors respond to accumulated toxic gas, not smoke or heat.<\/p>\n
The price is usually lower than combined detector models.<\/p>\n
Can be used either standalone or integrated with a hub-based smart system.<\/p>\n
