1.0 Introduction
The ISA-60M W/MRI-5175 is an ambient air monitoring system that measures oxygen concentrations in magnetic resonance
imaging environments. The ISA-60M control panel is capable of monitoring from 1 to 3 MRI-5175 remote sensors. Note: The
ISA-60M and MRI-5175 are produced as an aligned set and should be installed as such. Some features of the monitoring
system are as follows:
continuous monitoring of the sample air
continuous LCD display oxygen concentrations, at ISA-60M
menu driven operational and maintenance controls
menu driven calibration procedure
audio and visual alarms indicate unsafe conditions
alarm relay contacts available on terminals
a fault relay and visual fault alarm
alarm acknowledgement capability including audio defeat, ISA-60M control only
mA output for each channel
internal non-magnetic metallic coating of MRI-5175 to minimize RFI/EMI

3.0 Installation
3.1 Mounting of Instrument
Mount the ISA-60M and MRI-5175 instrument on an appropriate vertical surface using the mounting flanges provided. Avoid
areas with excessive vibration or temperature extremes. See Figure 3.
It is recommended to use #8 drywall anchors and screws for mounting the ISA-60M and MRI-5175 to a drywall/sheetrock
surface.
Non-magnetic mounting hardware is required for control panels located in the magnet room.
