FireClass 500 - Description of Control Panel Terminals

Description of the Terminals
This section describes the Control panel terminals.
n
Main Board terminals
+L1-/LEFT (+)Loop 1-Positive signal, left side.
(-)Loop 1-Negative signal (return), left side.
+L1-/RIGHT (+)Loop 1-Positive signal, right side.
(-)Loop 1-Negative signal (return), right side.
+L2-/LEFT (+)Loop 2-Positive signal, left side.
(-)Loop 2-Negative signal (return), left side.
+L2-/RIGHT (+)Loop 2-Positive signal, right side.
(-)Loop 2-Negative signal (return), right side.

Each Loop supports 250 (Analogue detectors, Input
modules, Conventional Zone modules, Manual callpo
-
ints, Output modules and Sounders). In all the control
panel supports up to 500 devices with 2 Loop.
LC
Conventional Input Line - Supervised and
Bypassable (Disabled) — This line supports 30 con
-
ventional fire devices (Optic Smoke detectors, Heat de
-
tectors, Manual callpoints).
Connect terminal [LC] to ground terminal [ M]) using a
3900 ohm resistor (orange-white-red). A 680 ohm resi-
stance (normal value for Fire detectors) parallel to the
3,900 ohm resistor will activate the programmed actions
and preset times of the Conventional Line outputs and the
Non-supervised output (terminals NC, NO and C).
+
The Conventional Line supports 30 Conventional
detectors. ATTENTION: DO NOT connect more
than 500 detectors and/or manual call points to
each main PCB.
[M]
Negative.
485
Serial Bus Terminals for FC500REP repeater pa
-
nels (maximum 8) and FC500 as Slave panels (maxi
-
mum 7). Serial bus terminals [+] and [-]; 27.6 V power
voltage terminals [M] and [24V].
AUX
Auxiliary power 24 V (0.5A max) Power supply to
devices that operate at 24 V (powered by the standby
batteries):
Ø Positive (27.6 V) on terminal [24A];
Ø Negative on terminal [M].
AUX-RES
Auxiliary power 24 V (0.5A max). The
system will interrupt power from terminal [24R] during
Reset. Power supply to devices that operate at 24 V
(powered by the standby batteries):
Ø Positive (27.6 V) on terminal [24R];
Ø Negative on terminal [M].
[NC][NO][C] FIRE
Non-supervised fire output. Dry
contact relay for non-supervised devices:
Ø
During standby status —— terminal [C] closes to ter
-
minal [NC];
Ø
In the event of fire —— terminal [C] closes to terminal
[NO].
[NC][NO][C] FAULT
Non-supervised fault output. Dry
contact relay for non-supervised devices:
Ø
During standby status —— terminal [C] closes to ter
-
minal [NC];
Ø
In the event of fault —— terminal [C] closes to termi
-
nal [NO].
+
EN54-2 cerification applies ONLY when, FAULT
output is not J (EN 54-1) type, therefore this output
MUST NOT UTILIZED to manage Fault transmis

sion devices.
+BAT2- Terminals to connect the batteries inside the
FC500 control panel (see Figure2).
+BAT1- Terminal to connect remote batteries or Po

wer supply.
PS1 BAQ140T24 power supply first connector.
PS2 BAQ140T24 power supply second connector.
OS1...OS8
Programmable, Silenceable, Bypassa-
ble (Disabled), Supervised Outputs
.
These are normally-open terminals (open-collector)
which will close to ground, when the connected event
becomes activ, and will remain in this state until the ge-
nerating event has ended (so after a manual reset or a
fault restore.
Ø
These outputs can be bypassed via the DISABLE
menu.
Connect an EOL 27.000 ohm resistor between termi
-
nals [OS] and [ M] of these outputs. This will allow the
control panel to detect and signal when the outputs are
shorted and/or open.
+
NOTE: The EOL resistor must be connected to
the last device on the Supervised output. Connect
a diode (1N4002 or 1N4007) in series to the devi
-
ces connected to these outputs.
O9...O16
Programmable, Silenceable, Bypassable
(Disabled) NOT Supervised outputs —— These are
normally-open terminals (open-collector) which close to
ground when the connected event will active. These ter
-
minals will remain closed to ground even after the gene
-
rating event has ended. These outputs can be forced to
standby (Not programmable polarity) by resetting the
control panel.
