Gent S4-711-V Dual Optical Heat Sensor with Voice

The Gent S4-711-V Dual Optical Heat Sensor with Voice is an intelligent S-Quad multi-sensor designed for use with Gent Vigilon analogue addressable fire alarm systems. Combining dual optical smoke sensing with heat detection, the device provides fast and reliable fire detection while helping to reduce unwanted false alarms.

Smoke detection performance is enhanced through patented dual optical scatter technology, enabling the sensor to distinguish between genuine fire conditions and environmental factors such as dust or steam. This allows the detector to be configured for specific risks and challenging environments while maintaining accurate fire detection.

The integrated voice sounder enables pre-recorded messages to be stored within the device and triggered during alarm conditions. Clear voice alerts help occupants understand the situation quickly, supporting faster and safer evacuation.
