To Order Call Toll Free: HGD-3000 Hydrogen Gas / Smoke Detector with Intrusion Alarm Model # HGD-3000 The HGD-3000 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. Smoke Detection 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 HGD-3000 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 buildup 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. Automatic Operation and Continuous 24/7 Monitoring Highly sensitive and stable solid state hydrogen sensor Sensitive photoelectric smoke detector module Internal thermostat for automatic exhaust fan control at 40°C (104°F) with ±5° adjustable range Save insurance costs - reduce insurance premiums when placed in battery charging rooms Technical Specifications Detection: Alarms: Relay Connections Mounting: Operating Environment: Power Requirements: Hydrogen Gas, Smoke, Temperature, Intrusion 10A Relay for Exhaust Fan, 1A Relay for Loss of Power, 1A Relay for Smoke Alarm, 1A Relay for Intrusion, 1A Relay for 2% H2 Concentration RJ45, Punch-Down Block (4) 4.5 mm (3/16 in) screws Temperature: -10 – 40 °C (14 – 104 °F) Utilities and Power Plants UPS Power Systems Fuel Cell Test Stations Nuclear Waste Reforming Hydrogen Refueling Stations Fire Department Battery Suppliers Battery Charging Rooms Motive Power Golf Cart IEEE Standard 450; National Protection Agency (NFPA) Article 64; NFPA 2: Hydrogen Technologies Code; Uniform Building Code (UBC) Section 6400; National Electric Code (NEC) Section 480.9 (A); NEC 501.125 (B); NEC 501.105 (1)-3 - use in Class 1 Division 2 Group B.
