Gent S4 Dual Optical Heat Sensor with High-Power Red VAD – S4-711-VAD-HPR
The S-Quad range of multifunction devices combines advanced fire detection sensors with integrated sounders, speech alerts, and EN54-23 certified visual alarms, offering maximum flexibility for building protection. The S4-711-VAD-HPR enhances occupant safety by delivering highly visible visual alerts and pre-recorded voice messages to ensure clear communication during emergencies.
Its innovative design positions the LED visual alarm at the centre of the sensor, while the sounder and speech circuits are discreetly integrated, providing a compact and aesthetically pleasing multi-function solution.
Visual alarms and voice messages are fully synchronised across the control panel, ensuring a consistent and unambiguous alert for all building occupants. The S4-711-VAD-HPR offers a cost-effective solution for integrated fire alarm signalling.
