Figure 6. The Controller Setup Screen
Setting up the Analog Output
For those applications requiring control of
an exhaust or supply damper actuator, the
analog output must be configured accordingly.
To access the analog output configuration
settings, select the Unit Setup option from
the Main Setup Menu , and then select the
Controller Setup option.
At the Controller Setup menu, select the
Analog Output option (see Figure 6 ) to
begin specifying the settings based on the
specific application requirements. At the first
configuration screen, the user is prompted
to select an action mode (direct or reverse
action), and the output range of 0-5/0-10V or
1-5/2-10V. The second screen allows the span
of the output to be limited to a percentage of
the selected range. These settings only relate
to AO-1.
Changing the Isolation Mode
The FMS-1655L can be set for positive,
negative, or neutral modes of isolation. To
change the isolation mode, select the Unit
Setup option from the Main Setup Menu , and
then select the Room Setup option.
At the Isolation Room Setup menu, select the
Isolation Mode option which allows the user
to select one of three isolation modes, unless
the available modes has been restricted
to either positive or negative plus neutral.
Changing the mode of isolation automatically
selects the pre-programmed setpoint and
analog output action mode associated with
each mode.
Adding Password Security
The FMS-1655L menu system can be
protected by adding up to 10 multi-level
passwords to the system. The Password
Setup option on the System Setup menu
allows the user to manage the security
passwords. Options on the Password Setup
menu include those for adding, editing, and
deleting entries from the system as shown in
Figure 7 .
To add a new password entry, select the Add
Password option from the Password Setup
menu, which prompts the user to enter a
minimum of four and up to eight digits. There
is also an option that allows all of the system
password entries to be purged.
Once a valid password has been specified,
the user is prompted to specify one of four
access levels: unrestricted, standard, basic,
and restricted. The first password entry is
automatically saved as unrestricted.
All password entries are saved to non-volatile
memory. In the event that a password has
been forgotten, there is a factory-default
password that will provide unrestricted access
to the user menu system. Please consult the
factory for more information regarding this
password.

Changing Display Settings
The Safety Halo™ feature significantly
enhances the status visibility of individual
units installed along a long corridor or
hallway, and allows an unsafe condition to be
immediately recognized. The Safety Halo™
display settings may be configured using the
Safety Halo™ option on the Display Setup
menu.
This option may be disabled if not required
by the installation, which simply turns off the
Safety Halo™ edge lighting. If enabled, the
brightness may be adjusted from full intensity
down to barely visible in daylight conditions.
