The return wire from the field contact is wired to the FC terminal on each
respective alarm module. Since the alarm system provides the power to the
field contacts, it is important to verify that no other voltage source is present
on either the H or FC terminals.
NOTE:
Please refer to the transmitter drawing on the enclosed CD.
In general, the solid-state alarm system is a floating system. The V+ and V-
should be verified as ungrounded
Power Supply
Verify the polarity of connection to the alarm systems.
In large systems, verify that the wire sizes are efficient for high current use
of the power leading to the alarm cabinets. To protect the larger alarm
chassis, it is common to provide more than one input to the cabinet in
which each section is provided with a separate filter, fuse and supply input
terminals.
