The Solar Outdoor Siren is a self-sufficient siren for Z-Wave security systems. Due to its large solar panel, it can be used without any additional power supply or batteries. The siren can be installed on any place on the outside of the house and can be controlled using Z-Wave. This way it extends security systems and calls attention in case of a triggered alarm. The siren issues a very loud sound (105 dBm) and in parallel some stroboscope light.
