Application Notes
  • The HD-11 is not designed to measure compliance with Occupational Safety and Health Administration (OSHA)commercial or industrial standards.
  • When the unit is powered up it performs a self-test during which the green LED light will blink for a period of one and one-half to two minutes. Afterward, the green LED light will turn on continuously to indicate the unit is in normal operation (ARMED). If the self-test fails or the green LED light does not turn on continuously do not use. Failure to do so may adversely affect product performance and result in sickness or death.
  • Immediately exit the environment if there is an alarm condition on the detector. Failure to do so may result in sickness or death.
  • This detector will only indicate the presence of combustible gas at the sensor. Combustible gas may be present in other areas. Accommodation spaces should be well ventilated when household cleaning supplies or similar contaminants are used.
