The SBS-H2 Hydrogen Detector is a complete hydrogen monitoring system with visual and audible alarms.

The Storage Battery Systems SBSH2 comes complete with the main display, a highly accurate hydrogen gas sensor and a 25 ft. cable. This unit can be powered with either AC or DC power and can be mounted directly to a wall or to an electrical box making it extremely versatile and very user friendly.

The SBS-H2 includes relays for remote connection to alarm/monitoring systems and for control of external relays or an exhaust fan.


  • Dual AC or DC power supply connections
  • Ideal for remote locations
  • Provides coverage redundancy in large monitoring spaces (up to 3 sensors)
  • Sensor LEDs indicate which sensor is detecting hydrogen
  • If loss of power, system will open 1% relay
  • Protects life, property and company profits
  • Modular design detector does not require complete replacement for repairs


  • Wall or 2-gang junction box mountable
  • Mechanical relays are easily accessible:
    • Warning 1% relay, 15A @ 120VAC; 10A @ 277VAC; 10A @ 28VDC
    • Alarm 2% relay 1A resistive @ 30VDC, 0.5A @ 125VAC
  • Redundant power supply capability (DC power supply will operate as backup power source)
  • SBS-H2 display allows for 3 sensor inputs to increase coverage area
  • Display and relays can be tested by pushing the red “TEST” button
  • Sensors can be tested in the field with the P/N H2-TESTKIT option

SBS-H2 System Diagram

Warning Settings: When 1% hydrogen is present in the air the yellow warning light will come on and the warning relay contact will close allowing power to peripherals, such as a vent fan or other devices.

Alarm Settings: When at least 2% hydrogen is present in the air the red warning light will come on and an audible alarm and strobe activate with corresponding Sensor LED. In addition, a second alarm relay contact will close, which can be used to shut down the system or notify a building alarm system or other devices.
