1GENERAL INFORMATION
1.1 WARRANTY
The AMC-1BXX Gas Monitor is warranted against defects in material and workmanship for a
period of two years from date of delivery. Maintenance items are not warranted. During the
warranty period, The Armstrong Monitoring Corporation will repair or replace components that
prove to be defective in the opinion of AMC. Any equipment deemed to be defective by the user
should be returned to The Armstrong Monitoring Corporation for evaluation (see product return
below). Site visits by Armstrong personnel, to evaluate/repair equipment, are not covered by this
warranty unless covered under site contract. AMC is not liable for auxiliary interfaced equipment,
nor for consequential damage. This warranty shall not apply to any product, which has been
modified in any way, which has been repaired by any other party other than a qualified technician
or authorized AMC representative, or when failure is due to misuse or conditions of use.
Note: extended warranty and mail in calibration programs are available (please call 1-800-465-
5777) or see our contacts page at www.armstrongmonitoring.com
1.2 LIABILITY
All AMC products must be installed and maintained according to instructions. Only qualified
personnel should install and maintain the equipment. The AMC-1BXX Gas Monitor must not be
located in hazardous locations where combustible gases could be 100% LEL(potentially explosive
environments).
AMC shall have no liability arisingfrom auxiliary interfaced equipment, for consequential damage,
or the installation and operation of this equipment. AMC shall have no liability for labor or freight
costs, or any other costs or charges in excess of the amount of the invoice for the products.
THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED,
AND SPECIFICALLY THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. THERE ARE NO WARRANTIES THAT EXTEND BEYOND THE
DESCRIPTION ON THE FACE THEREOF.
1.3 PRODUCT RETURN
All products returned for warranty or service should be shipped by prepaid freight and will be
accepted only with RMA or repair number issued by AMC. All products returned to the client will
be shipped by freight collect.
1.4 CONTACT INFORMATION
For information please call 1-800-465-5777, visit www.armstrongmonitoring.com or email
directly [e-mail].

1.5 MODIFICATIONS AND SUBSTITUTIONS
Due to an ongoing development program, AMC reserves the right to substitute components and
change specifications at any time without incurring any obligations.
1.6 GLOSSARY
Act Delay
The delay in seconds between the gas concentration reaching an alarm
setpoint, and the corresponding alarm level activating.
Alarm
Alarm is an audible, visual, or physical presentation designed to warn the
instrument user that a specific level of a dangerous gas/vapor concentration
has been reached or exceeded.
Calibration
Calibration is the procedure used to adjust the instrument for proper response.
Calibration
Gas
Calibration Gas is a gas of known concentration(s) used to set the instrument
span.
Gas
Concentration
Gas Concentration is measured in:
•PPM
•%LEL
•% Volume
Hysteresis
A user specified difference, or delta, from an alarm setpoint. Used to prevent
undesired repeated toggling of alarm activation. The concentration must return
above/below the setpoint +/hysteresis (based on a decreasing or increasing
alarm type) before an alarm level can become inactive. Hysteresis does not
affect the activation (only de-activation) of an alarm, which is based solely on
the alarm setpoint.
LEL
Lower explosive limit is the lowest concentration (percentage) of a gas or a
vapor in air capable of combusting in the presence of an ignition source (arc,
flame, heat).
Min Run
The minimum time in seconds that an alarm level will remain active, even if the
gas concentration has returned above/below the setpoint +/hysteresis(based
on a decreasing or increasing alarm type).
PPM
Parts Per Million (1% volume = 10,000PPM)
Percent by
volume
Concentration of gas in a mixture expressed as a percentage of total volume.
Span
Full range of a sensor i.e. a CO sensor with a full range of 0-100 PPM has a
100 PPM span.
T90
Response Time in seconds to achieve 90% gas concentration reading. This a
typical calibration point that allows for sensor aging, but tends to be less
accurate than a T99 calibration,
T99
Response Time in seconds to achieve 99% gas concentration reading. This is
a more accurate calibration point.
Zero
Buffering
Zero buffering is transmitter function which forces the gas concentration
reading to zero when sensor is exposed to low concentration of a gas. The
zero buffer is indicated in the sensor specification.
Zero Gas
Zero gas is gas in which the target gas is not present. The presence of oxygen
is required. Clean air is an excellent source for zero calibration. A known gas
concentration can be entered during zero calibration.

3PRODUCT DESCRIPTION
The AMC-1BXX Gas Monitors are designed to provide continuous, reliable monitoring of ambient
air for the target gas(es) via onboard sensor module.
The Monitor provides a digital representation of the gas concentration, this information is
displayed locally via OLED. Plug-and-play modular architecture accommodates; hot-pluggable
Power/Comms via the BusPower Module and field replaceable Sensor Modules (eligible for the
EZ-CAL exchange program).
In addition, each Monitor features alarm / system status indicators, audible feedback, 2 relays, 2
analog outputs and color-coded connection terminal blocks, as listed and described herein.
NOTE: The AMC-1BXX is a variant of our UTx platform. As such many of the menu items directly
reference the parent product.
