What is the life expectancy of the hydrogen gas sensor?
The sensor is rated for 5 years; after this time the sensor may start to become overly sensitive to gases. We recommend replacement or refurbishment of the sensor at this time. Changing the sensor is simple, quick, & can be done while online.
What are the limitations of the smoke and infrared intrusion alarm?
The IR sensor has a range of 9 meters and covers 30 degrees. If mounted in a large area, the sensor should be aimed towards a door, or at the equipment being protected.
Do the additional features of the HGD-3000 hydrogen gas detector decrease the life expectancy of the sensors or boards?
No, the additional features do not negatively impact any functions of the HGD-3000 hydrogen gas detector.
Does the HGD-3000 require additional maintenance and calibration after installation?
No, as described above the sensor is rated for 5 years. During this period the HGD should be maintenance free.
Is the HGD-3000 rated explosion proof?
No, the unit is not rated explosion proof. The intrinsic design of the unit is to prevent and explosive atmosphere from forming by alarming and switching proper ventilation services on.
Does the unit alarm to an external building control system?
Yes, the unit has 10A dry contact relays for smoke, intrusion, 2% alarms
How does the detector connect to the optional breakout box?
The breakout box connects to the detector box via a standard style 8-connector, 8-contact telephone-type (RJ45) modular cable.
What standards does the HGD-3000 satisfy?
Beyond making your facility environment safer for employees, the HGD-3000 fulfills the following standards: 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 Division2 Group B
