5.2 Controlling Three NACs and One Door Holder With One Input
In this application, the power supply has been set as a master with synchronized
outputs. All four FCPS-24FS output circuits, three NACs and one door holder, can be
controlled from one input such as an addressable control module as illustrated in Figure
5.2. The control module can be powered from the FCPS-24FS auxiliary 24 VDC power
output (TB4, Terminals 9 & 10).
The control module is shown to demonstrate the use of a remotely mounted device
associated with an addressable fire alarm control panel. The module could be replaced
with any circuit capable of polarity reversal, such as an FACP Notification Appliance
Circuit.
