DO NOT USE FOR
The GD-2B is NOT intended for use in industrial applications such as refineries, chemical
plants, etc. The GD-2B does NOT detect carbon monoxide. Do NOT mount the GD-2B in
a corner. The GD-2B is designed for connection to Fire Alarm/Burglary Control Panels.
Do not connect the GD-2B to Fire Alarm Circuits, or Burglar Alarm or other signals. The
Alarm Control Panel must be dedicated to gas detection or have alarm devices that

bathrooms - alcohol’s, ammonia, cleaning solvents, paint thinner, gasoline vapors, and
aerosol propellants (aerosol cans such as hair spray usually contain a combustible gas)
may cause nuisance alarms.
GD-2B may not function effectively below 32 F or above 120F. Using the detector
outside of this temperature range may adversely affect product performance and result in
sickness or death.
