Inside the apartment is still a gas boiler installed and after recurring reports of faulty gas heaters seemed that as a meaningful thing. The treacherous is that you can not smell or taste carbon monoxide. Without such a detector has no chance to notice an increase of CO in the home.
The detector is like most other similar design easily installed. You just have to the mounting unit (narrow plastic ring) mounted with the supplied wall plugs / screw and then lock the detector via rotary motion in the ring.
This works the detector is indicated by a green LED that flashes every 30 seconds. If the LED flashes yellow, the battery must be changed. On alarm, the LED flashes red.
The button on the detector may be a false alarm will be muted and the alarm will be tested. For the two types of alarm smoke and CO there are different sequences of notes: smoke is indicated by a (slower) Di-Di-Di and CO with a fast dididi sequence.
For those who CO sources in the house have (boilers, thermal baths, chimneys), the installation of this detector is highly recommended.
The only complaint I can mention is the fact that the manual is in English only. Who can not speak English and buys the detectors, the function should be possibly be explained by someone with English language skills.
