Red Dutch Tone Wireless Wall Sounder

SGRS100-H - Red Dutch Tone Wireless Wall Sounder

The Dutch tone wireless wall sounder is an acoustic output device which is activated by a specific command sent from the control panel, through a translator module and other possibly present expander modules, in case of fire or emergency situations; this device provides a European tone set. The communication between the sounder and the translator / expander module(s) is wireless via the Sagittarius bidirectional protocol.
This sounder allows the installer to choose among three different tones and to set the volume by directly and manually acting on the device.


- Bi-directional wireless communication
- Self optimizing wireless amplitude and frequency
- Automatic wireless channel hopping
- Fully intelligent
- High reliability and sensitivity
- Utilizes standard low cost lithium battery technology, fully monitored
- The Wireless Wall Sounder is equipped with a bicolor LED (red/green) that provides visual indication for functional conditions and battery levels
- If a battery fault condition is detected on the Wireless Wall Sounder, a fault message is sent to the control panel via translator / expander. This kind of fault condition is locally signaled by the module's visual LED indicator
- The Wireless Wall Sounder is provided with a tamper detection switch-spring system, and, in case of removal of the cover from its
box, it sends a tamper detection message to the control panel
