The Gent S4-770 is an intelligent analogue multisensor combining optical smoke and heat detection with a built-in sounder. By integrating advanced processing within both the sensor and the control panel, it delivers rapid response to genuine fire events while minimising false alarms.
Part of the S-Quad range, this device represents leading-edge fire sensing technology. Its combination of multiple sensing elements enables quick, accurate fire detection by identifying products of combustion such as smoke, heat, and carbon monoxide. Smoke detection is enhanced through patented dual optical scatter technology, allowing configuration to filter environmental factors like steam or dust, significantly reducing false alarms.
The S4-770 offers exceptional flexibility, allowing programming to suit specific site conditions. Different sensitivity states can be configured using combinations of optical, dual optical, heat, and CO detection, tailored to varying room conditions or times when interference is more likely.
