HGD-3000i H2 Hydrogen Gas & Smoke Detector with Intrusion Alarm
Hydrogen Gas Detection
The HGD-3000 H2 Hydrogen Gas and Smoke Detector with optional Silent Intrusion Alarm is designed for unattended battery installations or remote shelters containing gassing lead acid batteries and charging systems. The HGD-3000 will turn on an exhaust fan when hydrogen gas levels reach 1% and will alarm at 2%. This alarm consists of a local 80db horn, a flashing red LED, and a dry contact switch closure for remote alarming.
The photoelectric smoke sensor detects minute combustion products from smoldering wire insulation, battery cases, and other material. When smoke is detected, a distinctive alarm is emitted from the 80db horn and a separate dry contact switch is activated. At this time, the exhaust fan is inhibited in order to deny the fire increased oxygen from outside air.
Temperature, Loss of Power, & Intrusion
During normal operation and in the absence of an alarm condition, an internal thermostat will turn on the exhaust fan at a preset temperature to reduce heat build-up in the room. Loss of power to the unit will also generate a dry contact alarm. Additionally, an optional infrared intrusion alarm will trigger a silent dry contact switch.
