GENERAL SAFETY INFORMATION
INTENDED USE
The GD-2B is a low voltage (9-32VDC, 12-24VAC) electronic detector of combustible,
heating type gases. The GD-2B is designed for connection to Fire Alarm/Burglary Control
Panels. Alarm control panels that work on 12 or 24 VDC can provide battery backup to
the GD-2B detectors. This combustible gas detector has been designed for methane
(natural gas) and propane (LP) gas. It is NOT designed to detect smoke, fire or carbon
monoxide.
LIST OF WARNINGS AND CAUTIONS
Each person using this equipment must read and understand the information in these
User Instructions before use. Use of this equipment by untrained or unqualified
persons, or use that is not in accordance with these User Instructions, may adversely
affect product performance and result in sickness or death.
Use only for monitoring the gas which the sensor and detector are designed to
monitor. Failure to do so may result in exposures to gases not detectable and cause
sickness or death. For proper use, see supervisor or User Instructions, or call
Macurco Technical Service.
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.
This detector helps monitor for the presence and concentration level of certain
specified airborne gases. Misuse may produce an inaccurate reading, which means
that higher levels of the gas being monitored may be present and could result in
overexposure and cause sickness or death. For proper use, see supervisor or User
Instructions, or call Macurco Technical Service.
The GD-2B is not designed to measure compliance with Occupational Safety and
Health Administration (OSHA) commercial or industrial standards. When the unit is
turned on it performs a self-test, which activates the audible and/or visual alarms. If
the self-test fails, or all the alarms do not activate, 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.
2
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.
Do not cover or obstruct visual alarm LED. Doing so may adversely affect product
performance and result in sickness or death.
Do not disassemble unit or attempt to repair or modify any component of this detector.
This detector contains no user serviceable parts, and substitution of components may
adversely affect product performance and result in sickness or death.
CAUTION
Avoid the use of harsh cleaning materials, abrasives and other organic solvents. Such
materials may permanently scratch the surfaces; damage the sensor, labels, or
instrument housing.
If you have any doubts about the applicability of the equipment to your job situation,
consult an industrial hygienist or call Macurco Technical Service.
USE INSTRUCTIONS AND LIMITATIONS
Each person using this equipment must read and understand the information in these
User Instructions before use. Use of this equipment by untrained or unqualified persons,
or use that is not in accordance with these User Instructions, may adversely affect
product performance and result in sickness or death.
USE FOR
The GD-2B is an electronic detector of combustible, heating type gases (natural gas and
propane), designed for connection to alarm control panels. It can operate on 12 to 24
VDC power from standby or interruptible panel power, or be powered separately. The
GD-2B is intended for installation in buildings in non-hazardous locations such as
residences, retail stores, office buildings, and institutional buildings.
Use only for monitoring the gas which the sensor and detector are designed to monitor.
Failure to do so may result in exposures to gases not detectable and cause sickness or
death. For proper use, see supervisor or User Instructions, or call Macurco Technical
Service.
3
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
provide a distinctive alarm for gas detection. Do NOT mount the GD-2B in kitchens or
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.
GENERAL DESCRIPTION
The GD-2B is a low voltage (9-32VDC, 12-24VAC) electronic detector of combustible,
heating type gases, that has been calibrated for methane (natural gas) and propane (LP)
gas. The GD-2B is designed for connection to Fire Alarm/Burglary Control Panels. The
GD-2B has a SPST Alarm relay, for connection to control panels or other devices. The
GD-2B does NOT detect carbon monoxide. The GD-2B has an optional internal audible
sounder.
