Ø
EN61000-6-3 for emissions.
INTRODUCTION
The FC410LI Line Isolator Module is designed to be used on the FC addressable
controller loop circuits. It monitors the line condition and when detecting a short cir-
cuit will isolate the affected section whilst allowing the rest of the addressing circuit
to function normally. The purpose of the FC410LI Line Isolator Module is to ensure
that, on a looped addressable system, no short circuit fault can disable more de-
tection devices than would be lost on a conventional non-addressable fire circuit.
INSTALLATION TO FC470CV ANCILLARY COVER
1) Assemble the FC410LI to the FC470CV Double Gang cover, using the
four screw and washers provided.
2) Fit cover onto dual-gang backbox.
CABLING
Cables are to be selected in accordance with the system design document and
the requirements of the applicable standards. One pair of terminals is used to
provide a spur circuit (S+/S-). Two pairs of connection terminals (R+/R- and
L+/L-) are provided on the terminal block. These terminals are used for connect-
ing the module on to the addressable circuit. The maximum section of the cable
that can be connected at any one terminal is 2.5mm
based on the characteristics of the cable and the load.
WIRING NOTES
The following notes apply:
1) There are no user-required settings (such as switches or headers) on
the FC410LI.
2) All wiring must conform to the applicable standards.
3) All conductors to be free of earths.
4) Connect loop wiring. For FC410LI typical wiring configurations (see Fig. 1b).
5) Verify the correct polarity of wiring before connecting the FC410LI to the
addressable loop circuit.
6)
It is possible to connect a maximum of 32 devices between two loop iso-
lators (FC450IB o FC410LI), note that in the device counting process,
each FC410MIO or each FC410SIO adds a double value.

WARNING: DO NOT MEGGER LOOP WIRING WITH LINE
ISOLATOR MODULES CONNECTED.
The Line Isolator Module is not designed to work with line voltages above
the specified maximum 40 Vdc. This means that continuity testing of the
loop wiring with Line Isolator Bases connected must be done using a voltage
between 20-40 Vdc.
The resistance measurement range on conventional voltmeters use low
voltage only, therefore, the following method can be employed to confirm
loop integrity.
A power supply capable of providing 30-40 Vdc with a 300 to 600 mA current
limit is connected to one end of the loop (in correct polarity). A voltmeter is
connected to the other end of the loop or any base along the loop to verify
the wiring up to that point.
If there is no voltage out at any measured point, this may be due to:
1) Loop Open Circuit - wiring incomplete to part of the loop.
2) Incorrect Polarity - FC410LI Line IsolatorModules will appear as a short
circuit if they are wired with incorrect polarity.
3) Loop Short Circuit - If this occurs between two FC410LI Line Isolator
Modules, it will isolate that section of the line, which will then appear as
an open circuit.If this occurs between the supply and the first FC410LI
Line Isolator Modules, the supply output will go low due to the internal
current limit.
ASSOCIATED EQUIPMENT
The module fits onto a standard dual-gang backbox.

Switches are normally closed.
If a short circuit is detected on the spur, both
switches open.
If a short circuit is detected on the left hand side,
the left hand side switch opens.
If a short circuit is detected on the right hand side,
the right hand side switch opens.
