Ajax 107291.172.WH1 FireProtect 2 AC (CO) Jeweller Wireless Mains-Powered Fire Detector with CO Sensor, 110–240 V~ Mains, White
About this product
The Ajax FireProtect 2 AC (CO) Jeweller (107291.172.WH1) is a wireless mains-powered fire detector with a chemical CO sensor, in white, that raises an alarm when the accumulated dose of carbon monoxide is exceeded. It runs from 110–240 V~, 50/60 Hz mains with a non-replaceable lithium backup battery, has a built-in siren, and communicates with a hub (or range extender) using Jeweller communication technology.
Key features
- Chemical CO sensor with a sensor service life of 10 years
- CO alarm over 50 ppm (0.005%) in 90 minutes or less, over 100 ppm (0.01%) in 40 minutes or less, and over 300 ppm (0.03%) in 3 minutes
- Built-in siren: volume 85 dB at a distance of 3 meters
- Mains power 110–240 V~, 50/60 Hz, with up to 2 W of mains power consumption
- Backup: 1 non-replaceable lithium battery CR-2/3AZ
- Radio communication range up to 1,500 m between detector and hub (or range extender) in an open space
- Fallback interconnection: the initiating detector sends an alarm directly to other detectors, even if connection with the hub is lost
- Tamper alarm on attempts to detach the detector from the surface or remove it from the mounting panel
Frequently asked questions
At what carbon monoxide levels does the FireProtect 2 AC (CO) Jeweller raise an alarm?
It raises an alarm if the accumulated dose of CO is exceeded: over 50 ppm (0.005%) in 90 minutes or less, over 100 ppm (0.01%) in 40 minutes or less, and over 300 ppm (0.03%) in 3 minutes.
How is the detector powered?
It is mains powered at 110–240 V~, 50/60 Hz, with up to 2 W of mains power consumption. A non-replaceable lithium battery, CR-2/3AZ, allows it to operate autonomously without the main power source.
How long does the CO sensor last?
The sensor service life is 10 years. After 10 years of operation, the detector must be replaced with a new one.
How loud is the built-in siren?
The built-in siren has a volume of 85 dB at a distance of 3 meters.
Do the detectors still alarm together if the hub connection is lost?
Yes. Via fallback interconnection, the initiating detector sends an alarm directly to other detectors and all connected detectors activate the buzzer within a minute, even in the worst-case scenario of losing connection with the hub.
What comes in the box?
The complete set is the FireProtect 2 AC (CO) Jeweller, the SmartBracket mounting panel, WAGO 221 3-conductor terminals — 2 pcs. (pre-installed in SmartBracket), an installation kit and a quick start guide.
