Ajax 52257.150.BL1 Wireless Heat, Smoke and CO Detector, 10-Year Sealed Batteries, Black
About this product
The Ajax FireProtect 2 SB (Heat/Smoke/CO) Jeweller, article code 52257.150.BL1 in black, is a wireless combined heat, smoke and CO detector with sealed batteries. It detects smoke, dangerous temperatures and carbon monoxide indoors, sounds an 85 dB in-built siren and reports alarms by Jeweller radio to a hub up to 1,700 m away in an open space.
Key features
- Three sensors in one: smoke sensor, heat sensor and CO (carbon monoxide) sensor
- Double-spectrum optical smoke sensor that does not react to water vapour
- Heat sensing to the requirements for Class A1R heat detectors (EN 54-5 and BS 5446-2)
- Chemical CO sensor with accumulated-dose alarm thresholds
- In-built siren: 85 dB at a distance of 3 meters
- 2 non-replaceable lithium batteries with 10 years of battery life
- Jeweller radio communication range up to 1,700 m in an open space
- Tamper alarm on attempts to detach the detector or remove the mounting panel
Frequently asked questions
What does the FireProtect 2 SB (Heat/Smoke/CO) Jeweller detect?
It has a smoke sensor, a heat sensor and a CO (carbon monoxide) sensor, so one detector covers smoke, dangerous temperatures and carbon monoxide.
Can the batteries be replaced?
No. It runs on 2 non-replaceable lithium batteries with 10 years of battery life. After 10 years of operation, the detector must be replaced with a new one.
How loud is the siren?
The in-built siren has a volume of 85 dB at a distance of 3 meters.
What is the wireless range?
Radio communication range is up to 1,700 m between the detector and a hub (or radio signal range extender) in an open space, using Jeweller communication technology.
Can it be installed outdoors?
No. The device is designed only for indoor installation, with an operating temperature range from 0 °C to +50 °C and protection class IP20.
