legacy panels (FC510 and FC520) connected by Ethernet
through the FC500IP3 module showing the real time status
and alerting the operator once an event occurs in one of
the monitored systems.
Description
Inputs
FC503: The one main loop (three sub loops) manages up
to 250 devices.
FC506: The two main loops (six sub loops) manage up to
500 devices (250 devices per main loop).
Outputs
This section describes how the control panel outputs
operate.
Supervised outputs
With this output, the control panel can detect and
signal short circuits and power supply interruptions.
Bypassable disabled outputs
You can disable, by means of the respective key,
this type of output.
Silenceable outputs
To stop this type of output, you can use the
Silence/Resound Sounders key. You can silence the
outputs for an indefinite period during Day Mode or for the
programmed silence time during Night Mode.
Operating features
You can program the FC503 control panel to provide
WARNING or Delay to Alarm status before ALARM status.
The WARNING display signals the WARNING status. If a
detector exceeds its warning threshold, the control panel
generates a warning. The input module also generates a
warning state; a useful feature for implementing the
Systems Supervision capability.
Warning status signals:
•Control panel buzzer; 2 seconds of sound at 440 Hz and
then 2 seconds of pause.
•A WARNING message on the LCD display
•The WARNING output points if a user enables the Delay
to Alarm option.

6
Delay to Alarm
If a zone generates an alarm during Day Mode, the control
panel starts the Delay to Alarm Time. The Delay to Alarm
status signals are:
•Control panel buzzer; 0.5 seconds of sound at 880 Hz
and then pause for 0.5 seconds.
•Blinking on the Delay to Alarm LED for the first eight
zones only.
•Message ALARM+DLYTIME on the LCD display.
•Activation of respective outputs, if the user enables the
Delay to Alarm option.
Note: If the control panel detects alarm conditions during
Night Mode or from a callpoint, the control panel generates
an instant alarm.
Take the following actions during the Delay to Alarm
status; see Access to signaling and commands.
•Access Level L1: to activate an Evacuation Alarm,
press and hold the Evacuate Key.
•Access Level L2: to stop the Silence disable outputs and
interrupt the Delay to Alarm Time, press the Silence key.
When the Silence LED is on during Silence status, press
the Silence key to release the Silenceable outputs, or
press the Reset key to restore standby status.
If the control panel operates in Night Mode, the control
panel exits from Silence status automatically when the
programmed Silence time expires.
Alarm
When the Delay to Alarm time expires, the control panel
generates an alarm. The Alarm status signals are:
•Control panel buzzer; 0.2 seconds of sound at 3300 Hz
and then 0.2 seconds of pause.
•Alarm LED is on.
•An alarm message on the LCD display.
•Activation of the Fire and SC1 outputs.
•Activation of other outputs including SC2, OC1, or OC2 if
programmed.
During the Alarm status, the following can occur:
•At Access Level 2 you can stop the Silenceable outputs
by pressing the Silence key.
•At Access Level 2 you can press the Reset key and
Silence Buzzer.
Note: Refer to Access to signaling and commands for
further information.
During the Silence status when the Silence LED is on, use
the Silence key to release the Silenceable outputs. The
Reset key restores the standby status.
When the programmed Night Mode Silence time expires,
the control panels exits Silence status.
Day and night mode
The control panel can operate in Day or Night Mode. See
the relevant section in the “PC Programming” chapter.
If you silence the system in Day Mode, the Silence status
remains until you unmute the system, provided that no
other alarm incidents occur. If you silence the system
during Night Mode, the Silence status remains until the
Night Mode Silence time expires.
At default, the system is set to Day Mode. During Day
Mode, silenced alarms are not unmuted automatically.
Fault
This control panel can detect and signal the faults shown
in Table 2. Fault conditions signals are:
•Control panel buzzer; 1 second of sound at 660 Hz and
pause for 1 second.
•The Fault LED and relative Fault LED is on.
•A Fault message on the LCD display.
•Activation of the Fault output.
•Activation of other outputs including SC2, OC1 or OC2 if
programmed.
The Fault output and any additional programmed fault
outputs automatically restore to standby when fault
conditions clear.
Under certain circumstances, fault conditions may clear
spontaneously. If this occurs, the memory stores the event
until you reset the control panel. Blinking on the Fault LED
signals stored fault events.
Silence
This control panel provides a Silence key that can restore
the Silenceable outputs to Standby status.
When the Silence LED is on, this signals the Silence
status.
The Silence status remains until one of the following
occurs:
•You press the Silence key again
•The programmed Night Mode Silence time expires when
the control panel operates in Night Mode.
•A new alarm condition is detected.

Notes:
Before connecting the fire control panel to the PC
for the PC programming phase, remove the
jumper of the main board. See Figure 3, item 10.
When the programming phase finishes, replace
the jumper to ensure the Earth fault or Leakage to
Earth is detected.
To silence the buzzer permanently during
installation, engage the control panel at access
level 3 and remove the Jumper J5. See Figure 3,
item 7. A disabled buzzer causes the zonal LEDs
to flash and a “BUZZER OFF” string displays
alternately with the date and time on the panel
user interface. As a result of this procedure, the
timeout for the installer does not change. To
reactivate the buzzer, replace the Jumper J5 when
the installation process completes.

Telephone line
LE
Terminals for connecting the external telephone line.
LI
Terminals for connecting the internal telephone line.
Connect these terminals to other telephone devices that
need to share the same phone line as the fire panel.
There is also a terminal for connecting the earth wire.
Fire
[NC][NO][C]
The following features describe the [NC][NO][C] fire
output:
This is a non-supervised fire output; a dry contact relay
for non-supervised devices.
The fire output activates by default when the first fire
event occurs.
Deactivation of the fire output occurs during the panel
reset.
The fire output may be muted; see the default
programmable option=NOT silenceable.
It is not possible to disable the fire output.
The fire output may be programmed to work differently,

20
only with the FC503_FC506 software.
During standby status, terminal [C] closes to terminal
[NC].
In the event of fire, terminal [C] closes to terminal
[NO].
Note: EN54-2 certification applies only when the fire
output is not C or J or G (EN 54-1) type. Therefore, you
must not use this output to manage fire alarm devices, fire
or fault transmission devices, or an automatic fire alarm
system.
Fault
[NC][NO][C]
This is a non-supervised fault output; a dry contact relay
for non-supervised devices.
The fault output activates when:
The first fault event occurs.
In the case of logic fault.
In the case of total loss of power.
Other features of this fault output include:
Deactivation of this fault occurs during the panel reset.
It is not possible to silence the fault output.
It is not possible to disable the fault output.
The fault output may not be programmed to work
differently.
During standby status, terminal [C] closes to terminal
[NC].
In the event of fault, terminal [C] closes to terminal
[NO].
Note: EN54-2 certification applies only when the fault
output is not J (EN 54-1) type. Therefore, you must not use
this output to manage fault transmission devices.
SC1, Sounder circuit
This sounder circuit is a supervised, silenceable,
bypassable or disabled bell output for the alarm signaling
devices. Terminals for the connection of devices that are
activated with the positive 24V must be supervised.
During standby status, negative pull-down to 0 V on [+]
terminal; positive pull-up to 27.6 V on the [–] terminal.
When control panel is in alarm status, positive pull-up to
27.6 V on the [+] terminal; negative pull-down to 0 V on the
[–] terminal.
Silence the SC1 using the menu command DISABLE.
Note: You cannot program this output, it activates every
time the control panel goes into ALARM status.
SC2, Sounder circuit
This sounder circuit is a supervised, silenceable,
bypassable or disabled programmable bell output, for the
panel alarm signaling or panel delay to alarm or panel
warning or panel fault or 1,2,3 or 4 software zones(OR)
alarm, or 1,2,3 or 4 software zones(OR) warning or 1,2,3
or 4 software zones (OR) fault or 1,2 or 3 points(OR) alarm
or 1,2 or 3 points(OR) delay to alarm or 1,2 or 3
points(OR) warning or 1,2 or 3 points(OR) fault.
During standby status, negative pull-down to 0 V on[+]
terminal; positive pull-up to 27.6 V on the [–] terminal.
When a programmed event occurs, positive pull-up to
27.6 V on the [+] terminal, negative pull-down to 0 V onthe
[–] terminal.
You can force the SC1 and SC2 outputs to standby by
resetting the control panel. The SC outputs hold standby
status for the programmed silence time. If alarm conditions
are present when the programmed silence time expires for
the SC1 or another programmed event for the SC2, they
reactivate.
Notes:
SC1, SC2 accept devices that operate within
SELV limits only.
The SC2 output, if programmed as SC1, is type C.
If using a 2-wire connection loop, the EN54-2
certification only applies when the total number of
devices, including detectors and manual
callpoints, does not exceed 32.
Auxiliary outputs
OC1-OC2
These outputs are silenceable, bypassable or disabled,
unsupervised and programmable. These are open-
collector terminals for the panel alarm signaling (default) or
panel delay to alarm or panel warning or panel fault or
1,2,3 or 4 software zones(OR) alarm, or 1,2,3 or 4
software zones(OR) delay to alarm, or 1,2,3 or 4 software
zones(OR) warning or 1,2,3 or 4 software zones(OR) fault
or 1,2 or 3 points(OR) alarm or 1,2 or 3 points(OR) delay
to alarm or 1,2 or 3 points(OR) warning or 1,2 or 3
points(OR) fault, which will be close to ground, when the
connected event becomes active, and will remain in this
state until the generating event has ended (so after a
manual reset or a fault re-store).
You can program the output OC1 to signal the telephone
line failure so it can combine with a relay, for switching
from the primary phone line to the reserve line.
You can also force the OC1 and OC2 outputs to standby by
resetting the control panel.
The OC1 and OC2 outputs activate with a delay equal to
the delay to alarm time when the programmed event
occurs.
Note: EN54-2 certification applies only when OC1 and
OC2outputsare notC orJor G,EN 54-1 type. Therefore,
do not utilize this output to manage the fire alarm device or
fire or fault transmission devices or automatic fire alarm
system.
