Gent S4 Dual Optical Heat Sensor Black Body (S4BK-711)

Gent S4 Dual Optical Heat Sensor Black Body S4BK-711

The S4BK-711 from the Gent range is a S4 Dual Optical Heat Sensor Black Body.

The S4BK-711-V Dual Optical Black Heat Sensor with Voice is a Gent Vigilon S-Quad sensor with a unique combination of sensing elements to provide quick, intelligent fire decisions. Smoke detection is enhanced using patented dual optical scatter technology. This allows it to be configured to filter specific risks such as steam and dust, resulting in significantly reduced false alarms.

Voice messages stored on a memory chip in the sensor can be triggered to give clearly understood messages leading to quicker and safer evacuation.

A new concept in fire detection – a truly intelligent analogue sensor combining exceptional computing power in the sensor as well as the panel to achieve an extremely fast response to a real fire whilst minimising the risk of false alarms.

Key Features

• The multi-sensor combines heat (H), carbon monoxide (CO), optical forward scatter (OFS) and optical backward scatter (OBS)
• The patented dual angle optical scatter technology allows identification of the particle source filtering potential false alarms due to steam and dust
• The gas sensing element (CO) within the chamber monitors the concentration of carbon monoxide, a product of incomplete combustion in some fire types, and potentially life threatening. The CO sensor allows rapid fire detection, with smouldering fires, in areas where smoke detectors could register false alarms
• Combined CO gas sensing with dual angle optical and heat allows a higher level of false alarm immunity whilst still improving the detection speed of certain types of fire
• Each sensor element has sensitivity settings which can be adjusted to suit the environment / application and can be programmed for different time periods during the day or night
• Repeat fire LED output as standard (if monitored input not used)
• Operational LED blink ‘On/Off’ option
• Monitored Input – which can be Fire, Fault or Supervisory
