Controlling Three NACs and One Door Holder With One Input
Applications
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 31.
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-24S 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.
4.
An End-of-Line Resistor must be installed between terminals 5 & 6 for control module wiring
supervision (the ELR value is dependent on the module employed).
5.
For a list of compatible devices, refer to the
Notifier Device Compatibility Document #15378
