Figure G-2. Stand-Alone Control Box Front Panel
G-2.1 Fire Alarm Trouble
The ARIES NETLink supports an external FIRE ALARM TROUBLE indicator and controller for City
of Chicago applications. The external indicator is a 24 Vdc bell. When the ARIES NETLink panel
enters a Trouble state, the System Trouble LED on the ARIES NETLink front display begins to flash.
Immediately, the Stand-Alone Control Box activates the separately-installed bell, annunciating a
Trouble State. The bell may be silenced by moving the box’s toggle switch to “Bell Silence”. When
the switch is in the “Bell Silence” position, the Bell Silenced indicator will light. When the System
Trouble clears, if silenced, the bell will resound to warn the operator that the toggle switch is in the
“Bell Silence” position. To return the Stand-Alone Control Box to its normal mode, move the toggle
switch to “Bell Normal”. A pushbutton switch is also located on the front of the box (labeled “Bell
Test”) to permit testing of the bell as desired.
G-2.2 City Tie Trouble
The ARIES NETLink supports an external CITY TIE TROUBLE indicator and controller for City of
Chicago applications. The external indicator is a 24 Vdc bell. If the wire connection to the Master Box
becomes disconnected (either by turning the City Disconnect Key Switch or by some other means),
the Stand-Alone Control Box activates the separately-installed bell, annunciating a Trouble State.
The bell may be silenced by moving the box’s toggle switch to “Bell Silence”. When the switch is in
the “Bell Silence” position, the Bell Silenced indicator will light. When the City Tie Trouble clears, if
silenced, the bell will resound to warn the operator that the toggle switch is in the “Bell Silence”
position. To return the Stand-Alone Control Box to its normal mode, move the toggle switch to “Bell
Normal”. A pushbutton switch is also located on the front of the box (labeled “Bell Test”) to permit
testing of the bell as desired.
Note: If a hardware problem occurs with the City Tie Expansion Card, the ARIES NETLink panel
will go into a Trouble state and the FIRE ALARM TROUBLE indicator will activate.
