Gent S4 Dual Optical Heat Sensor with Voice Sounder and High-Power Red VAD – S4-711-V-VAD-HPR
The S-Quad range of multifunction devices combines advanced fire detection sensors with integrated sounders, voice alerts, and EN54-23 certified visual alarms, providing maximum flexibility for building protection. The S4-711-V-VAD-HPR enhances safety by delivering highly visible visual alarms alongside pre-recorded voice messages, ensuring all occupants are clearly alerted during an emergency.
Its innovative design incorporates the LED visual alarm at the centre of the sensor, with the sounder and voice circuits discreetly integrated, resulting in a compact, aesthetically appealing multi-function device.
Visual alarms and voice messages are fully synchronised across the control panel, providing a consistent and unambiguous alert to all building occupants.
