Sentra | Wireless indoor siren for the socket, suitable for the QT1 & QT2

The Sentra Wireless Plug-In Indoor Siren provides powerful audible and visual alerts for your security network. With a volume of 105 dB and a red flashing light, it reliably signals alarm conditions and effectively deters potential intruders.

Installation is incredibly simple: Plug the siren directly into a power outlet – no complex wiring is required. Thanks to the built-in backup battery, the siren remains operational for up to 12 hours during power outages, ensuring your protection even during these times.

Various audible signals inform you about system statuses such as armed, disarmed, or partially armed. In the event of an alarm, a specific tone sounds, which varies depending on the type of alarm (burglary, fire, water, or panic), enabling a quick response.

The siren is optimally compatible with the Sentra alarm control panels QT1 and QT2.
