Description
Once the alarm value is reached, the device activates an acoustic and visual alarm to alert you of potential hazards. The built-in signal transmitter achieves a sound level of over 85 dB(A) at a distance of three meters.
The integrated LCD-display informs about the current CO-concentration. In addition, three LED displays show the operating status, error statuses and active alarms.
The carbon monoxide detector supports mute, self-test, and low battery warning. The replaceable CR123A lithium battery is designed for a service life of up to ten years.
Due to its compact design, the device is suitable for wall mounting in apartments, restaurants, hotels and other interior spaces.
