SBS-H2 Hydrogen Gas Detector Complete Hydrogen Detection System The SBS-H2 Hydrogen Detector is a hydrogen detection system with visual and audible alarms and 1% and 2% hydrogen relays. The system comes complete with the main control, a highly accurate hydrogen gas sensor and a 25 ft. cable. This unit can be powered with AC and/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. •• Main control •• Hydrogen sensor •• 25 ft. cable •• Substations •• Battery rooms •• Uninterruptible power supply (UPS) •• Battery cabinet systems •• Battery charging areas •• Hydrogen fueled back-up power systems Protects life, property and company profits Ideal for remote locations Fail safe mode in event of loss of power Up to three (3) sensors can be installed to main control to meet space coverage requirements Universal power inputs: 110/220 Vac and/or 12–48 Vdc input Strobe light for visual alerts Sensor status indicator LEDs on the main control Modular design for optimal placement of sensor(s) NRTL/C Certified: UL Std. No. 61010-1 CAN/CSA-C22.2 No. 61010-1-12 •• Wall or 2-gang junction box mountable •• Mechanical relays are easily accessible: •• Warning 1% relay, 15 A @ 120 Vac; 10 A @ 277 Vac; 10 A @ 28 Vdc •• Alarm 2% relay, 0.5 A resistive @ 28 Vdc, 0.5 A @ 125 Vac •• Redundant power supply capability; dual AC and/or DC power supply connections (DC power supply will operate as backup power source) •• Indicator LEDs can be tested by pushing the red “TEST” button •• Sensors can be tested in the field with the P/N H2-TESTKIT Main Control Mounting and Power Options

Alarm Settings: Should the hydrogen gas concentration reach 2% by volume, the “2% Alarm” red LED will light up, the strobe will flash and an audible alarm will sound. In addition, the 2% internal relay will energize and can be used to activate a building management/alarm system (via SCADA/Modbus).
