FC506 is an analogue addressable fire control panel with two
main loops (six sub-loops). The panel can support up to 500
addressable devices and a maximum of 250 devices in a
single main loop, and 256 zones. BAQ140T24 switching
power supply powers FC506 at 5.5A @ 27.6 ±1 %V. Suitable
batteries include 2 * 12 V/ 17Ah or 2 * 12 V/ 38Ah. The user
interface has LEDs and icons.
The FC506 fire control panel is a modular system. The
configuration of the FC506 system depends on the size
and requirements of the application; therefore, some of the
described devices and functions may not be present on
your system.
The FC506 system consists of the following components:
• One FC506 control panel
• Max. 8 FC500 repeaters
• Max. 4 FC500MFI multifunction modules
• Max. 7 client panels
• Max. 500 devices in six different sub-loops or two main
loops (250 devices max per main loop)
The FC503 and FC506 fire control panels allow you to
manage the functions of the fire control system up to
2000m (loop) with shielded 2 core cable 2x2.5mm².
Accessory items
FC500 repeater
Repeaters are peripherals that provide system status
information, emit audible signals, and allow users to
control the functions of the FC503 and FC506 system (up
to 1000m, with twisted pair shielded cable).
FC500MFI
The FC500MFI is a programmable multifunctional module
for connection to a real time event printer. The terminal
blocks also make it possible to connect a standard
interface to remotely control and manage a set of inputs
and outputs to control the panel.
FC500IP
This module connects the control panel to a Local Area
Network (LAN).
FC503 and FC506 client
The FC503/FC506 master control panel can support up to
seven FC503 or FC506 client control panels. These
control panels can be used to expand the FC503/FC506
system in modular way.
FireClass FC500 (FC501_FC503_FC506) Console
This is a software application operating on Microsoft
Windows 7 and higher. The console offers a quick and
easy way to program the control panel and also provides
event log and printout functions.
FireClass console multi account engine (FCMAE)
The FCMAE allows you to monitor multiple FireClass
systems across the world from a single workstation. It
manages up to 32 FC500 series panels (FC501, FC503,
FC506, FC510, and FC520) connected to Ethernet
through the FC500IP3 module. It shows the real time
status and alerts the operator when an event occurs in one
of the monitored systems.

Description of keys
To manage the panel from the User Interface (UI), use the
following controls:
• Alphanumeric keypad. Numbers 0 – 9 and letters A-Z.
• Cursors keys: Up, Down, Right, and Left
• ESC key
• ENTER key
• HELP button to open the Help screens on the Display.
See Figure 2.
• Command keys
Note: Use the cursors keys Up, Down, Right, and Left,
and the command keys LAMP TEST and SILENCE
BUZZER, and the alphanumeric keypad to enter the
characters A,B,C,D,E, and F. Use these characters to
enter hexadecimal numbers for planned future use.
The function of the cursors keys, the ESC key, the ENTER
key, and the command keys, is different in every LCD
display and is fully described in this manual. Also, the
amount of time spent pressing the keys has a different
function in the different LCD displays. In future, it will be
possible to use the HELP key to access more information.
SILENCE / RESOUND / SOUNDERS
The control panel can operate in day mode or night mode.
If the system is silenced during day mode, the silence
status remains until the system is unsilenced (unless new
alarms or faults occur). If the system is silenced during
night mode, the silence status remains until the night mode
silence time expires. On power up, the system starts in
day mode by default. During this operating mode, silenced
alarms/faults will not be unsilenced automatically.
RESET
Reset will stop alarm, delay to alarm, warning, and fault
conditions. Access to this command is limited to
authorized personnel using an installer or user access
code. The system reprocesses any alarm, delay to alarm,
warning or fault signal that is not cleared by a reset.
Command keys cannot be used when a reset is running.
The repeaters can be reset by using the user access code.

Delay to alarm status
The Delay to Alarm status indicates that an input
point (detector) has exceeded its alarm threshold.
The fire control panel will not generate an alarm until
the preset delay to alarm time ends. However, if a
second input point such as a detector in the same
SW zone, detects alarm conditions during the delay
to alarm state (and the double knock (DK) option has
been programmed for that zone), the fire control
panel generates an instant alarm.
If the fire control panel is operating in night mode, it
generates instant alarms only and Delay to Alarm
status is bypassed automatically. If an alarm
procedure is already running, the fire control panel
ignores delay to alarm conditions.

Locate loop break screens
These screens are used to manage the Locate loop
break procedure that helps to understand where the
loop is broken. The results of this procedure provide
the number of sensed detector on the left and on the
right side of the analyzed loop.
The screen's sequence is depicted in Figure 15.
Figure 14: Locate loop break screen

Page 18 of 38
Note: During the locate loop break procedure all the
detectors power down. At the end of the procedure, a
full loop initialization is executed. The devices not in
the configuration are not found.
Locate the not addressed devices
In the case of a NOT POGRAMMED DEV. fault, it is
possible to locate all the unaddressed devices. For
visibility, all the unaddressed devices that have an
LED will be activated (constant on). The sounders
start to sound, while the beacons start to flash.
Ifthere are toomanyunaddressed devices,the
overall current required to keep all the LEDs,
sounders, and beacons active at the same time may
be so high that the loop overcurrent protection
circuit is triggered.
