Intrinsic Safety; General Description - MSA ICM 2000 Plus Operation Instructions Manual

Advertisement

An SCBA cannot be upgraded until the following inspec-
tion and all required changes have been completed.
1997 NFPA COMPLIANCE INSPECTION
Inspect the entire SCBA after it is cleaned and sanitized.
NFPA-1500, as well as ANSI Standards Z88.2 and Z88.5,
describe three levels of inspection procedures which are
to be performed. Refer to these documents, or to an
inspection program prepared by a health professional in
establishing an inspection program.
Do not inspect the apparatus before cleaning if there
is danger of contacting hazardous contaminants.
Clean and disinfect first, then inspect. Failure to follow
this precaution may cause inhalation or skin absorp-
tion of the contaminant and result in serious personal
injury or death.
Prior to installation of the ICM Unit 2000 Plus, the SCBA
must be upgraded to be compliant with the 1997 edition
of the NFPA-1981 standard. The components must be in
good working order, free of damage and significant wear.
(See SCBA Inspection Instructions)

DESCRIPTION
WARNING
WARNING
WARNING
The ICM Unit 2000 Plus turns on automatically when the
user opens the SCBA cylinder valve. The GREEN light on
the unit flashes to signal that it is activated and operating.
The ICM Unit 2000 Plus has 3 control buttons:
Mode Button
(green)
Panic Button
(red)
The RESET/OFF yellow button resets the device from the
full alarm mode. It also shuts the unit off after the cylinder
valve is closed and all air pressure is bled from the unit.
The center red (alarm) button activates the full alarm
mode with or without air pressure.
The mode button (green) will change the digital display
window. See the during use section for details.
The PASS function uses RED and GREEN light-emitting
diodes (LEDs) to display its status visually:
GREEN
LEDs start to flash when the cylinder valve
is opened and shows that the device is
operational.
RED
LEDs flash slowly when the device is in
pre-alarm;
LEDs flash rapidly when the device is in full
alarm.
Follow the donning procedures in the Air Mask instruction
manual to pressurize the system. As the pressure reaches
approximately 200 psig, both visible and audible alarms
activate automatically, indicating that the unit is functional.
When the system is fully pressurized, the alarm enters the
Monitor (normal) Mode. The unit remains in sensor mode
until the user shuts off the cylinder air and presses reset
button twice in quick succession.
If the user is motionless for approximately 18 seconds the
ICM Unit 2000 Plus goes into a pre-alarm. During pre-
alarm, the device sounds 3 progressively louder tones and
the RED light flash slowly. Movement of the unit cancels
the pre-alarm. If the user remains motionless for 12 more
seconds (approx.) the ICM Unit 2000 Plus goes into full
alarm. During full alarm the PASS repeatedly sounds two
high-pitched tones followed by a buzz. During full alarm
the RED lights also flash rapidly.
The ICM Unit 2000 Plus can be set into full alarm at any
time (even without air pressure) by pressing the alarm but-
ton.
