Fire Control Panel FS4000
- terminal “+24V” – positive lead of the stabilized direct current supplying the external devices
(light and sound signaling devices, executing devices and others);
- terminal “GND” – chassis ground (negative lead of the stabilized direct current supplying the
external devices);
- terminals “REL Fault/C”, “REL Fault/NO”
и
“REL Fault/NC” - potential free relay contacts.
Terminals “REL Fault/C” and “REL Fault/NO are connected where no fault condition is registered;
terminals “REL Fault/C” and “REL Fault/NC” where fault condition is registered.
-
terminals ''REL1/C”, “REL1/NO” and “REL1/NC ”- potential free relay contacts of REL1. In duty
mode there is a connection between terminals “REL1/C” and “REL1/N
С
, and in Fire condition
between terminals “REL1/C”
и
“REL1/N
О
”.
- terminals ''REL2/C” and “REL2/NO” - potential free relay contacts of relay REL2. In duty mode
there is no connection between terminals “REL2/C” and “REL2/N
О
”, in Fire condition there is a
connection between terminals ''REL2/C” and “REL2/N
О
”.

14.2.3.
Connection of extension module FD 4201
In Fire Alarm Control Panel FS 4000 there is a option for extension through module FD 4201.
The module FD4201:
- expand the panel’s outputs with additional 2, 4, 6 or 8 (depend from number of the lines in the
panel) relay non-potential outputs, activated trough fire;
- add interface RS485 for connection of the panel to local network. The connection between the
panel and the module is by connector on the panel.
14.3. Connecting fire detectors
Fire detectors are connected to the fire control panel by means of two-wire insulated line of total
resistance up to 100
Ω
. Recommended cross section of the wires depending on the length of the line
is:
♦
Up to 500 m
-cable 2
х
0.5 mm
2
♦
Up to 1000 m
-cable 2
х
1.0 mm
2
♦
Up to 1500 m
-cable 2
х
.1.5 mm

Before connecting a fire alarm line to the control panel, run a check with measuring equipment.
Where the installation is completed correctly (EOL module is mounted) between the + and the – of the
cable, entering the control panel, a resistance of 5.6 kOhm (+/-10%) shall be measured. Also, check
both cables to “GROUND” and the measuring equipment shall display that no leakage or connection
is registered.
