Connecting Repeater and Slave Control panel
An example of how to connect two FC500REP repea
-
ters and two FC500 SLAVEs is shown in Figure 10.
The RS485 port of the FC500 (terminals [ M], [+], [-]
and [24V]) accepts up to 8 FC500REP repeaters and
up to 7 FC500 SLAVEs, so a panel will be configured as
a "Master" control panel while the others seven will be
configured as "Slave" control panel; the eight Repea
-
ters will be the Repeaters of the "Master" control panel.
+
Assign an address to FC500REP repeaters ( see
the procedure "Programming from the Panel"
page 51).
Terminals [+] and [-] supply the power (27.6 V) to the re-
peater panels (see figure 10,11).
When a mains fault occurs, the Repeaters considerably
decreases the absorbed power, switching off the LCD
display backlighting (the LCD display backlighting
switches on again, for 20 sec. when a key will be pres
-
sed). But the absorption of the Repeaters connected to
the control panel, will contribute to run down the backup
batteries, and so the decrease of the Stand-by supply
time of the system.
When one control panel only is in the system all the Re
-
peaters must be supplied by the control panel itself, un
-
less a Power supply Station is in the system.
When several Control panels are in the system, the Re
-
peaters supply Load can be shared between these
Control panels (see Figure 11).
+
The control panel [24V] terminals must not be con
-
nected between them, because the switching Po
-
wer supply cannot work in parallel and the entry in
protection status (OFF) can be produced with the
effect of overloading the switching Power supply
still working.
Use shielded cable only, with one end of the shield
connected to the "Master" Control panel Negative
terminal and the other left free; the continuity, bet-
ween several segments of connection must be se-
cured (see Figure 11).
n Connecting Output Devices
The control panel has 8 supervised outputs, 8 NON su-
pervised outputs and 4 Bell outputs (supervised and
silenceable) .
+
NOTE: Output devices can be connected to the loops
by means of Output modules.
n
Bell Outputs
The Bell outputs are indicated by the letter NAC and
their address number.
