functionality of the kit. The loss of transmission in the loop causes an emergency operation in line
mode and a failure is reported (registered alarm). Communication with all equipment in the kit is
maintained. After the damage has been repaired, the transmission is automatically resumed in
standard mode and the damage signal is switched off. A failure of the COM line does not affect the
operation of the loop, but it can make it less resistant to interference.
- A double interruption/short circuit causes the transmission to cease only with devices in a loop
between interruptions/short circuit.

line. These devices need
not be of the same type. Both P-MACF, MAC-D-Min, MAC-Link etc. can be connected on
one line.

Note:
1.
The bus cables must be routed at a distance of at least 0.4m from power cables (230VAC,
400VAC)
2.
When connecting, remember that there must be one pair of wires connected to terminals
D+ and D-. This includes Global FireBUS
®
and Local FireBUS
®
loops.

Electrical connections and parameters.
13.1.
Power connection, SzA-FCK, SAP
Electrical connections should be made by persons with appropriate qualifications and
authorizations, in accordance with the standards and regulations in force in the country where the
device is installed. Connection methods are shown in the attached diagrams. The guidelines from
tables 13.2 - 13.6 show the electrical data of the equipment and the recommended cable cross
sections to be supplied from the electrical switchboard. The applied assumptions:
•
For 3x400VAC cables it has been assumed that the maximum share of hot zone does
not exceed 20% for 50m length, while the voltage drop is 3%.
•
For 1x230VAC cables it has been assumed that the maximum share of hot zone does
not exceed 20% for 60m length, while the voltage drop is 5%. In case of other
parameters, it is necessary to contact the manufacturer (reselection of cables).
•
For 1x24VDC power wires MAC-D MIN(2;4) regulators and PZ box it has been
assumed that the maximum share of hot zone does not exceed 20% for 40m length,
while the permissible voltage drop does not exceed 10%.
•
For 1x24VDC supply cables of P-MACF sensors it has been assumed that the
maximum share of hot zone does not exceed 20% for 100m length, while the allowed
voltage drop does not exceed 10%.
•
For 1x24VDC supply cables of TSS-X-24V it has been assumed that the maximum
share of hot zone does not exceed 20% for 135m length, while the allowed voltage
drop does not exceed 5%.
•
For bus cables, it is assumed that the cable length between the individual devices
must not exceed 250m.
