Applications

Controlling Three NACs and One Door Holder With One Input

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.

The following notes apply to Figure 5.2 on page 30.

1. The Output 4 door holder circuit will deactivate 10 seconds after Control Input #1 is activated

or AC power is lost.

2. When the FCPS-24FS power supply is in an inactive state (control module not active), a

trouble on the power supply will result in an open circuit condition on the control module
output circuit (monitored by an End-of-Line Resistor across Terminals 5 & 6). As an
alternative, the trouble contacts at TB5 of the power supply can also be used for independent
trouble monitoring.

3. Do not loop wires under screw terminals. Break wires to maintain proper supervision.
