Additional siren with battery back

The back-up siren will alarm other than a conventional siren:
Not only by a positive (+ 12V) or negative (GND) trigger signal (trigger), but also in case of failure or sabotage the power supply. The back-up siren is permanently loaded via a direct connection to the battery, ensuring an alarm over several minutes.
So it is ideal for vehicles whose battery or power supply is accessible from outside.
The back-up siren is the ideal accessory for GAS-pro and WiPro and is also suitable for alarm systems from other manufacturers

• Alarmed by trigger input of gas alarm / alarm
• Alarmed by high or low signal (12V or ground)
