Gent S4-711-V-VAD-LPR Dual Optical Heat Sensor Voice Sounder Red VAD

Gent S4-711-V-VAD-LPR S4 Dual Optical Heat Sensor with Voice Sounder and Standard Power Red VAD

The Gent S4-711-V-VAD-LPR S4 Dual Optical Heat Sensor with Voice Sounder and Standard Power Red Visual Alarm Device (VAD) is an intelligent analogue addressable multi-sensor designed to provide advanced fire detection, clear voice evacuation and highly visible alarm indication within a single device. Designed for use with compatible Gent Vigilon and Gent S-Quad analogue addressable fire alarm systems, it combines dual optical smoke sensing, integrated heat detection, a programmable voice sounder and an EN54-23 compliant standard power red VAD to deliver a complete life safety solution. 

Using Gent's advanced dual optical scatter technology and intelligent signal processing, the S4-711-V-VAD-LPR provides rapid detection of both slow smouldering and fast-flaming fires while helping to reduce unwanted alarms caused by environmental conditions such as dust and steam. The integrated voice sounder can broadcast up to four programmable evacuation messages, while the red visual alarm device improves occupant notification in noisy environments and for hearing-impaired occupants.

By combining fire detection, voice evacuation and visual alarm signalling into a single addressable device, the S4-711-V-VAD-LPR helps reduce installation time, simplify wiring and lower overall system costs, making it an excellent choice for modern commercial fire alarm installations.
