Section 4: Operating Instructions

4.1 Main Control Panel Keypad Labels

The NFC-50/100 is shipped with slide-in labels installed in the keypad as illustrated in the following figure. Blank labels are provided to
allow the user to customize the zone and message description. Remove the center piece to access the label slots. Using a small, flat
screwdriver, press and release the small plastic latch located on the left side of the center piece. The top row of labels can be easily
removed by sliding them down through the slots in the middle of the keypad and installed by sliding them up. The bottom row of labels
can be removed by sliding them up through the slots in the middle of they keypad and installed by sliding them down into position.

4.2 NFC-50/100 Switch Functions

The NFC-50/100 display consists of 38 tactile push-button keys. Pressing one or more of the keys while the panel is not in alarm will
select the corresponding circuit for paging or to generate a manually activated evacuation or drill signal. If the panel is in alarm, pressing
a key corresponding to an activated speaker circuit will turn off the circuit and turn on the Trouble LED.

All Call

Pressing this button activates all speaker circuits (that were not manually deactivated) for broadcast. ALL CALL paging from the main
console's microphone will override paging/manual activation operations initiated from the other consoles (NFC-LOC, NFC-RPU, NFC-
RM) or from a FACP (if programmed for priority to do so). If all consoles in the system are programmed for equal priority then the ALL
CALL will only occur when the system is not already in use (“System in Use” LED is not on, remote console active LED is not on).
Refer to the SYSTEM CONTROL button description. When the operator completes the page, any previously interrupted emergency
broadcast will resume. Previously initiated emergency broadcast will also resume after the push-to-talk (PTT) switch is held for more
than 3 minutes (timer is programmable).

MNS Control

This button is only used when the system is configured for combination fire/mass notification operation or mass notification only opera-
tion.

For mass notification only operation, pressing this button will activate the “MNS active” relay and the onboard NAC. A second press
will de-activate the “MNS active” relay, turn main control board NAC off, and cancel all broadcasting.

For combination systems (fire and mass notification) where mass notification has a higher priority through user programming, pressing
this button will result in the shutdown of audible FACP NACs and audio system speakers if they were active for fire. Pressing the button
again causes the FACP to re-activate audible FACP NACs and audio system speakers if they were previously active for fire.
