Sensor, additional siren & battery monitor

Note: Only usable in conjunction with the sensor alarm system (mobile or home).

The alarm siren adds a loud, audible deterrent to your sonsor alarm system in case of a break-in. Its volume is comparable to a smoke detector and is particularly unpleasant in confined spaces. Please be careful not to hold it too close to your ear to avoid hearing damage!

The integrated battery monitor can be used when you connect your sonsor alarm siren & battery monitor directly to your vehicle's 12V electrical system. This allows you to receive data on the current status of the connected battery directly in the sonsor app on your smartphone.
