Description
Introducing the S&S HGD Series 100 Hydrogen Detector will monitor hydrogen gas build-up in storage rooms and facilities that house batteries. The detector provides terminal block connections for single-phase 230 AC, 24VAC or 18-60VDC power. Detected Hydrogen levels are displayed in % Vol and traffic light indication – Green (Normal) Yellow (Warning) Alarm (Red).
The control relays are used to switch an extract fan and warning alarms, the detector also provides analogue outputs that can be connected directly to the fan speed
controller to regulate the fan speed. If the concentration of hydrogen gas detected reaches 1% Vol the screen will display yellow, and the warning relay will close activating the ventilation fan. If the concentration reaches 2% the screen will display red, and the alarm relay and an 80 dB internal warning will sound.
