The S4-711-V-VAD-LPR Dual Optical Heat Sensor with Voice and Low Power Red VAD is a Gent Vigilon S-Quad sensor that combines multiple sensing elements to deliver fast, intelligent fire detection. Smoke detection is enhanced through patented dual optical scatter technology, which can be configured to discriminate against specific environmental factors such as steam and dust, significantly reducing false alarms.
In addition to advanced detection, the S4-711-V-VAD-LPR offers a cost-effective solution for alarm signalling.
