The Ei208W Carbon Monoxide Alarm is supplied with a powered-for-life sealed Lithium battery.  It contains a high performance, proven 10 year electrochemical CO sensor to detect the presence of toxic levels of Carbon Monoxide (CO).   Each sensor is individually calibrated and tested in Carbon Monoxide gas to ensure accuracy.  

When the Alarm detects potentially dangerous levels of CO, the red LED flashes and if the CO persists the alarm will sound. The rate of flashing of the red LED indicates the level of CO. The higher the level of CO detected, the sooner the alarm will sound.

The AudioLINK feature available in the Ei208W facilitates acoustic download of the Alarm parameters and status using the Ei Electronics AudioLINK app.

The Ei208W may be interconnected wirelessly with the RadioLINK+ module Ei200MRF (sold separately or included in the Ei208WRF) to communicate with compatible Ei Alarms and accessories.  Up to 12 RF devices can be interconnected.

The Alarm self-checks its sensor, battery voltage and internal circuitry regularly.  Any fault condition will be indicated by a combination of visual and audible indicators (ie yellow flashes and beeps).  The Alarm also has an “End of Life” indicator (audible and visual) which will notify the user when the Alarm needs replacing at the end of its 10 year operational life.

The memory feature allows an Alarm that has previously activated to be easily identified (as the red LED will continue to flash for 24hrs after the event or afterwards when you press the Test button).

The Alarm is supplied with a twist-on mounting base which as multiple fixing points so it can be easily secured to a ceiling or wall.  Free standing install is also possible.
