A highly visible outdoor siren can act as a deterrent in itself. In the event of an alarm, the high-volume audible signal and flashing light clearly indicate danger, alerting not only you but also drawing the attention of those nearby to the event. Its weather-resistant design, external power supply option and battery life of up to 5 years make the SR250M a reliable long-term choice.
The SR250M communicates wirelessly with the Paradox M System, so in the event of an alarm, it is immediately activated by the control panel and alerts those nearby with audible and visual signals. The system continuously monitors the status of the siren, while the external power supply option provides even greater flexibility in how it can be used.
