Introduction
Following the installation, apply power to the
unit. Upon power up, the Safety Halo™ status
indication bezel will cycle through seven
colors (red, green, blue, yellow, magenta,
cyan, and white), and then the JCI splash
screen indicating serial numbers, firmware
version numbers, Neuron ID, Program ID, and
current network address will be displayed.
The splash screen remains displayed
for approximately 10 seconds, and then
disappears to reveal the main display screen.
The information displayed on the splash
screen during the power up sequence may
also be redisplayed using the About This FMS
option on the Diagnostics menu.
The FMS-1655L incorporates a full-color
touchscreen with an easy-to-use menu
system that allows the user to quickly setup
the controller for immediate use.
There are several hotspots that provide quick
access to various settings. Refer to page
for details on using these hotspots as display
settings shortcuts. Touching the screen
anywhere other than one of the reserved
hotspots invokes the menu system, unless
one or more security passwords have been
entered.
Main Display Screen
(Single Sensor Models)
All FMS-1655L units are shipped from the
factory in the neutral isolation mode, which is
represented by a blue screen with a slashed
circle. The information that is displayed on the
main screen includes the following from top to
bottom (see
Figure 1):
• Isolation room name in the upper window
(up to 25 characters)
• Current differential pressure (default
units: in wc)
• Current isolation mode and status
• Status icon centrally located
• Current relative humidity in the lower
window (if equipped)
• Current temperature in the lower window
(if equipped)
Located just below the lower window with the
temperature and humidity display is the Alarm
Audible button.
A green background with a check mark at the
center indicates that the current differential
pressure is within allowable limits of the
desired setpoint (see Figure 2).
A yellow background with an exclamation
point at the center indicates that the current
differential pressure has drifted outside the
allowable limits of the desired setpoint and is
in the caution range (see Figure 3).

A red background with an exclamation point
indicates that the current differential pressure
has reached an unsafe condition, as it is
beyond the safe operating range (see Figure

as well providing an audible alert of the
unsafe conditions.
