Product details
This Philio PSE02 Siren is a loud, multi-channel siren that works with any Vera controller, allowing you to program alerts for any event that occurs in your network. The Z-Wave Indoor Multi-Sound Siren is designed for wall-mounting in an electrical box, and it has a DC jack to receive power from a 5VDC power supply. The power supply wires can easily be hidden behind the siren, which also supports an optional backup battery (included). In case of a power outage, the siren will automatically switch to the battery for power.
