Cable Requirements

All cables should be specified and installed to meet the
requirements of local laws (see the schematic diagram
for a typical system layout).

Fire alarm cables must be separated from all other
wiring (not related to the fire alarm system).

Cable Types

For specific details on the cable types, and how they
should be run, refer to local practices and regulation.
You should refer to these for details. For the address-
able loops there is a wide range of cable types that can
be used.

Earthing

The addressable loop conductors must be isolated
from the earth. Any current leakage to the earth is
indicated as a fault.

Screening

If a cable with a conductive screen or a metal sheath
is used, this must not be connected to the addressa-
ble loop conductors. The recommendation is to join
the screens from each section of cable within each
loop de- vice to form a continuous cable screen.

Cable Routing

Ensure cables are routed to minimise coupling effects.
Try to avoid grouping power and signal cables together
in the same conduit or trunking. Feed the mains supply
into the housing through its own dedicated knockout.

RS 485 Networking

Copper cabling should always be used for the network.
In summary, the maximum distance between nodes is
1000 m using shielded twisted pair cable. Use shield-
ed cables only, with one end of the shield connect-
ed to the Control panel Negative terminal and the
other left free. The continuity between several
segments of connection must be secured

Mains Supply

The mains supply final circuit(s) to all parts of the fire
alarm system should be dedicated solely to the fire
alarm system, and should serve no other systems or
equipment. To facilitate local isolation during mainte-
nance, suitable means should be provided for double
pole isolation of the low voltage supply circuit that
serves the power supply and control equipment.
The power circuits of this Control panel comply with the
EN54-4 standard.
!
In order to comply with the Safety regulations
in force, the Mains must be equipped with a
bipolar isolating device for protection against
over voltage and short-circuit to the Earth
(e.g. an automatic isolating switch).
This Control panel is powered from the Mains:
110/230 VAC 60/50 Hz -15/+10%.
The FC501-L control panel provides housing for a

1.8 A switching power supply (BAW50T24).
 The FC501-H control panel provides housing for a
2.7 A switching power supply (BAW75T24).
 The FC501-HK control panel provides housing for
a 2.7 A switching power supply (BAW75T24).
STEP 1 – Mounting the panel

Note: The control panel is not weatherproof. Check
that the location is indoors, dry and free from ex-
cessive dust. The cover of the Fire Panel must be
able to open fully; the cover must be able to be
removed leaving the inside of the Fire Panel freely
accessible.
Work carefully through the following steps.
Remove the two screws and open the control panel

cabinet. Then lift the cover from the bottom to sepa-
rate it from the backplate.
Place the backplate on the selected wall and mark

the points for the drill holes, using the appropriate
tubular spirit level. For a more secure mounting
when particularly heavy batteries (12 Ah) are
used, utilize all the openings provided.
!
Check for water pipes and electrical wiring
before drilling.
Drill the holes and insert the plugs.
