Espire Mains Powered Carbon Monoxide Alarm with 10 Year Backup Battery (ES1CLV)

The Espire ES1CLV is a Grade D1 mains-powered carbon monoxide alarm designed for continuous toxic gas detection in residential fuel-burning environments, boiler rooms, and living spaces. Certified to EN 50291-1:2018, the unit incorporates an electrochemical CO sensor engineered for high stability and early detection of dangerous carbon monoxide concentrations.

Operating on a 230V AC mains supply (3.3W max, 0.5W standby), the alarm features a non-replaceable 10-year sealed lithium backup battery (3V CR123A) to ensure uninterrupted monitoring during power outages. System diagnostic features include automatic self-testing, a 3-LED status interface (Power/Fault/Alarm), an auto-dimming power LED for bedroom installations, an 85dB sounder at 3 metres, a 10-minute alarm hush function, and a 12-hour fault silence option. A 24-hour post-alarm memory feature provides visual indication following an event.

The ES1CLV mounts onto an anti-tamper lock-in wiring base, supporting hardwired interlinking across up to 28 compatible Espire mains safety devices over a maximum cabling distance of 300 metres. Hybrid wireless interlinking is enabled via the optional ES1RF RF-Link module. Housed in a flame-retardant, UV-stabilised ABS enclosure (Ø132mm x 59mm, UL94-V0 rated), the unit is backed by a 5-year guarantee.
