The Gent S4-711-V-VAD-HPR Dual Optical Heat Sensor with Voice Sounder & High-Power Red VAD – Model S4-711-V-VAD-HPR is a part of the S-Quad series. It brings together advanced sensing, audible alerts, speech capability, and EN54-23 certified visual alarm technology in one compact unit. This multi-functional design allows fire safety system designers to meet a variety of building coverage requirements with a single, elegant solution.
Using state-of-the-art detection technology, the S-Quad range ensures rapid and reliable emergency warning. Each device pairs a high-intensity visual alarm with pre-recorded voice announcements, ensuring clear and effective communication to all building occupants.
A distinctive design feature places the LED visual alarm centrally within the sensor, while housing both the sounder and speech electronics inside the same enclosure. The result is a neat, space-saving device that delivers both performance and aesthetic appeal.
To guarantee consistent messaging, all visual alarms and voice alerts are fully synchronised across the system, regardless of the control panel location.
