Hydrogen Gas Detector
Hydrogen Sensor and Monitoring System

The Hydrogen Detector is a complete hydrogen monitoring system with visual and audible alarms.The system comes complete with the main display, a highly accurate hydrogen gas sensor and a 25-ft. cable.
Lead-acid storage batteries emit hydrogen gas while discharging and recharging. Hydrogen concentrations of 4% to 75% by volume in air are potentially explosive. The SBS hydrogen gas detector is designed to allow dissipation and give warning before any concentration reaches the lower explosive limit (LEL) of 4%.  This unit is easy to install and very cost effective.
Includes hydrogen specific sensor for detection and monitoring of H2 gas and relays for remote connection to alarm/monitoring systems and for control of external relays or an exhaust fan.
This device can be used to meet the minimum requirements for your battery room to be in compliance with IEEE Std 484-2002, National Fire Protection Agency (NFPA) Article 64 and Uniform Building Code (UBC) Sect 6400.  Failure to monitor hydrogen gas production and alarm when certain thresholds are reached can void your insurance policy and exposes your company to severe risk should any injury result from a non-passive hydrogen gassing event.



Benefits

  • SBS exclusive
  • 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 or calibrations


Features

  • Universal power inputs: 110/220 Vac and/or 12-48 Vdc input
  • Push button diagnostic test
  • Audible and visual (strobe) alarms
  • Sensor has a temperature rating of -4??F to 176??F
  • Can operate in a wide range of temperatures and humidity


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, 15A @ 120VAC; 10A @ 277VAC; 10A @ 28VDC
        - Alarm 2% relay, 0.5A resistive @ 28VDC
  • 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 button
  • Sensors can be tested in the field with the P/N H2-TESTKIT option



Operation

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 a visual strobe alarm activate, with corresponding sensor's LED. In addition, a second alarm relay contact will close, which can be used to shut down the system and initiate a building alarm system or other devices.
