External Mains Adapter for POPP Smoke Sensor (POPE004001)

The external power supply enables a permanent mains electricity supply (220 V) for the Popp Smoke Sensor with Indoor Siren (POPE004001). Thanks to this option it isn't necessary to change batteries for the device's whole lifetime. Nevertheless the battery mustn't be removed as it's used for standby/failover power should a mains supply issue occur.
