Lead-acid storage batteries emit hydrogen while gassing during charge. Hydrogen concentration of 4% to 75% by volume in air are potentially explosive. SBS HGDI-DRDC 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 very easy to install and very cost effective.

This SBS HGDI-DRDC is required for your battery room to be in compliance with IEEE Std 450, National Fire Protection Agency (NFPA) Article 64 & Uniform Building Code (UBC) Sect 6400. Failure to monitor hydrogen gas production & alarm when certain thresholds are reached voids your insurance policy & exposes your company to severe risk should any in juries result from a non-passive hydrogen gassing event. The HDGI is an affordable piece of your safety plan.

The HGDI-REM optional remote display is a small monitor box that duplicates the LED indicator lights, the audible warning buzzer, and the push-to-test button on the HGDI-DR hydrogen gas detectors. The HGDI-REM is connected to the remote hydrogen gas detectors with standard crossover six-wire telephone cables. It may be located up to 1000’ away. 25’ cable comes standard.
