Top RM at good price

Installation is super easy and self-explanatory: Screw magnetic disk at the ceiling or attach with supplied hot glue (high adhesive strength). The smoke detector is simply plugged tuned to the magnetic disk.

It is great that the unit does not get any flashes with an LED or lights up, but has a test button. The alarm is loud enough to get everyone awake.

In addition, the RM are sounds of itself, if, for example. The battery is empty (lt. Information 60 days before it is empty), so that there is enough time to buy a new device. Furthermore, checks of RM every minute even to function, so it is also a signal of in the event of a fault. This feature I could not test, however, so far.

For smokers: The RM is also suitable for a smoking household, provided that it is occasionally aired, and the smoke is not up to the ceiling from the floor in the apartment.
