Carbon monoxide (CO) is one of the most dangerous threats in any indoor environment — invisible, odorless, and potentially deadly. Early detection is critical. FireProtect 2 AC (CO) Jeweller is a mains-powered wireless detector designed to identify dangerous CO levels before they become life-threatening, ensuring fast alerts and dependable protection.
Built to meet modern fire safety standards, this advanced detector combines continuous power, intelligent sensing, and seamless integration into the Ajax ecosystem.
Early Detection of Carbon Monoxide
Carbon monoxide poisoning can occur without warning, making reliable detection essential. FireProtect 2 AC is equipped with a high-precision chemical CO sensor with a service life of up to 10 years, designed to detect even low concentrations of CO.
The detector triggers alarms at critical thresholds:
50 ppm within 90 minutes
100 ppm within 40 minutes
300 ppm within 3 minutes
This ensures early warning — even before symptoms appear — allowing occupants to act quickly and safely.
Continuous Power with Backup Protection
FireProtect 2 AC is powered by 110–240 V mains, ensuring continuous operation without relying solely on batteries.
In the event of a power outage, a built-in backup battery keeps the device running, providing uninterrupted protection when it matters most. This combination delivers stable performance over its 10-year operational lifespan.
Instant Alerts and Clear Notifications
When dangerous CO levels are detected, FireProtect 2 AC activates a powerful 85 dB built-in siren, ensuring occupants are immediately alerted.
When connected to an Ajax system, users also receive real-time notifications through the Ajax app, clearly indicating:
The type of threat
The location of the detector
The exact time of the event
This level of detail enables faster, more informed responses.
Interconnected Alarm System for Faster Response
FireProtect 2 AC supports dual alarm interconnection, ensuring rapid alerts across the entire property.
Primary interconnection (via Ajax hub): activates all detectors within 20 seconds
Fallback interconnection (detector-to-detector): activates alarms within 60 seconds, even if the hub connection is lost
This ensures that every occupant is alerted, regardless of system conditions.
Built for Modern Installations
FireProtect 2 AC is designed with installers in mind, offering a fast and efficient setup process.
Key installation features include:
SmartBracket mounting panel with adjustable rotation
WAGO 221 connectors for quick, tool-free wiring
Secure locking mechanism for added stability
The device can be installed in as little as 90 seconds, making it ideal for both residential and commercial projects.
Reliable Wireless Communication
Using Ajax’s Jeweller radio technology, FireProtect 2 AC ensures secure and stable communication with the system.
Key communication benefits include:
Up to 1,700 m wireless range in open space
Encrypted two-way communication
Frequency hopping to prevent interference
Instant alerts for connection loss or jamming
This ensures consistent performance, even in challenging environments.
Smart Integration and Automation
When integrated into the Ajax ecosystem, FireProtect 2 AC goes beyond detection by enabling automated safety responses.
In the event of a CO alarm, the system can:
Activate ventilation systems to reduce CO levels
Unlock emergency exits for faster evacuation
Trigger connected devices and send visual verification through compatible cameras
This creates a smarter, more responsive safety system that helps protect both people and property.
Always Monitored, Always Informed
FireProtect 2 AC provides data-rich notifications and system monitoring, ensuring users and monitoring centers always have full visibility.
Features include:
Real-time system status updates
Detailed event logs (up to 500 events)
