Eaton SDR-2R-EXT-NC External Siren G2 Radio Backplate

The Eaton (Scantronic) SDR-2R-EXT-NC External Siren G2 Radio Backplate is a wireless external sounder designed for intruder alarm systems, providing a visible and audible deterrent when an alarm is triggered.

It is a Grade 2 radio sounder that communicates with compatible systems using encrypted two-way wireless signalling, removing the need for wiring between the control panel and the external siren.

Designed for external use, the unit combines a high-visibility housing with an integrated sounder and strobe, helping to alert occupants and draw attention to an alarm condition.

The radio backplate format makes it suitable for installations where running cables to an external siren is not practical, while still maintaining a professional and secure system setup.

It is intended for residential and light commercial applications, offering a straightforward wireless solution for external alarm notification and visual deterrence as part of a wider intruder alarm system.
