    Gent S4-770-S Optical Heat Multisensor and Sounder

    The S4-770 is an Analogue Addressable Multisensor (Optical Smoke & Heat) with an integral sounder built into the unit.

    A truly intelligent analogue sensor combining local processing in the sensor and the panel to achieve an immediate response to real fi res whilst minimising the risk of false alarms.

  • GENT Optical Heat-Sensor Sounder S4-770-S

    • Complete range of sensors with combinations of advanced sensing technologies including heat, dual angle optical scatter and carbon monoxide (CO)
    • Combined sensing of carbon monoxide with dual angle optical scatter and heat allows a higher level of false alarm immunity in presence of steam and while still maintaining the integrity of detecting fires
    • Each sensor has certified sensitivity settings that suit certain environments/applications and may be programmed for different times of the day if required
    • Short circuit Isolator in each device
    • Configurable input/output connection for remote indicator or supervisory input fully synchronised sound patterns via the control panel
    • Sensor sounders have adjustable sound level and tones to match system sounders
    • Sounder element monitoring and over-load protection to ensure operation even in event of cable fault
    • Sound output synchronised and compatible with S-Quad range of EN54-23 VADs
