The new Z-Wave plus smoke detector POPP warns of possible house fire. A nice detail to this new detector is that sets off all other smoke detectors of the same type in case of emergency. This communication function is a standard component of the unit and does not have to be set via the controller.
The detector also has a indoor siren which can be used independently from smoke alert, for instance in a Z-wave alarm system. The acoustic sound that is made by the siren will also be difficult in case of fire or alarm.
You can also connect this smokedetector to the 230V power network by installing this POPP power adapter.
