Descriptions of MCB terminals
Terminals
Description
24V, 0V, B and A
These terminals accept the connection of a repeat indicator
panel (Port 0). Also the power terminals may be used on a
Network node to supply BACnet Gateway.
NC, C and NO
These are auxiliary relay contacts. The auxiliary relay 1 is
Aux 1- 2-sets
normally de-energised and operates with any fire event. The
auxiliary relay 2 is normally energised and operates
Aux 2 - 1set
(de-energises) with any fault event.
0V, TX, A, RX
These are terminals for RS232 or RS485 (Port 1 or 2
and B
respectively).
L1, 0V, L2, 0V
These terminals accept the connection of system devices on
(Loop 1 and
a loop circuit that starts at L1 and ends at L2. Devices that
Loop 2)
are connected to the loop circuit include addressable fire
sensor/sounders, manual call points, interface units and
repeat/mimic panels.
MA1+, MA1-,
These terminals can accept two master alarm circuits that
MA2+ and MA2-
can operate 24V conventional alarm devices.
0V and MIP
These are monitored input terminals that can accept the
connection of a switch. An active input will trigger Command
build 250.
NC, C and NO
These are voltage free relay contacts (output) that operate
(clean contact)
with a fire event.
