SBS-H2 Hydrogen Gas Detector

Hydrogen Sensor and Monitoring 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.

Benefits

  • 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

Features

  • 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

Installation

  • 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, 1 A resistive @ 30 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

Detector can operate exhaust fans and building alarms / SCADA systems:

Warning Settings: Should the concentration of hydrogen gas in the air surrounding the sensor reach 1% by volume, the “1% Warning” yellow LED will light up on the main control of the unit. In addition, the 1% internal relay will energize and can be used to activate an external exhaust fan or a building management/alarm system (via SCADA Modbus).

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).
