The primary power input to the Control Panels is 120 VAC obtained from the
input side of the building main supply through an independent fused discon-
nect switch. The primary voltage is reduced and rectified to the proper
operating voltage. Terminals are also provided for connection of an emer-
gency battery supply which is automatically connected to operate the system
in the event of a failure of the primary power.
These Control Panels are either stand-alone units or custom configured to
meet a specific application.
This manual describes the Installation, Operation, and Maintenance of the
C-99A-12, C-99A-24, and C-100A-24 low voltage automatic fire alarm Control
Panels.
1.2 FUNCTIONAL DESCRIPTION
I
All the Control Panels operate identically except for the voltage and
I
current outputs. Figure 1-2 is a simplified version of the Control Panel
models.
1.2.1 Operating Principle
Three relays operate the Control Panel circuitry. The AC monitor relay and
the Alarm relay are voltage sensitive. This means they require the full DC
voltage applied across the coil before changing their state. The Trouble
relay is current sensitive. This relay is normally energized and is
de-energized whenever supervisory current is interrupted.
