It features dual optical heat sensing and a built-in short-circuit isolator, offering a cost-effective solution for comprehensive and reliable fire alarm signaling while minimizing false alarms.
Gent S4 Dual Optical Heat Sensor with High Power Red VAD – Model S4-711-VAD-HPR
The S-Quad series delivers a versatile range of multifunctional fire detection devices, combining advanced sensors, integrated sounders, voice messaging, and EN54-23 certified visual alarm devices (VADs). Designed for comprehensive building protection, these units ensure clear, highly visible alerts alongside pre-recorded voice instructions for effective emergency communication.
With a compact, streamlined design, the central LED visual alarm is built directly into the sensor head, while the sounder and speech components are housed internally. This provides both a space-saving and visually appealing installation solution.
All visual and audible alerts are synchronized across connected control panels, ensuring consistent and intelligible messaging throughout a building. The Dual Optical Heat Sensor with High Power Red VAD offers a cost-effective solution for high-performance fire alarm signaling.
Key Features & Benefits
- Multi-technology detection – combines heat sensing, dual-angle optical scatter, and carbon monoxide (CO) monitoring for accurate fire detection.
- Reduced false alarms – CO and optical scatter sensors work with heat detection to maintain reliability even in challenging environments, such as steam-filled areas.
- Customizable sensitivity – certified and adjustable sensitivity settings tailored for different applications and times of day.
- Integrated short-circuit isolator – built into each Gent S4-711-VAD-HPR device for system resilience.
- Flexible input/output options – configurable for remote indicators or supervisory inputs, with sound patterns fully synchronized through the control panel.
- Adjustable sound output – selectable tones and volume settings for alignment with other system sounders.
- Built-in monitoring and overload protection – ensures the sounder remains operational even with cable faults.
- Full-range synchronization – sound and light output across all S-Quad EN54-23 VAD units remain perfectly aligned.
