15: External Audio Input Operation - Honeywell NOTIFIER NFC-50/100 Instruction Manual

Operating Instructions
• For the data bus to peripheral consoles, the data bus fault LED turns off
• For the onboard NAC, the NAC fault LED turns off
• For the audio riser, the audio riser fault LED turns off
• For a peripheral console, the associated peripheral console fault LED turns off
• For a distributed amplifier, the associated distributed fault LED turns off
For distributed amplifier restorals, the following will occur on the display when the operator uses the DIAGNOSTIC button to select a
distributed amplifier for more specific indication.
• For power present, the AC power LED turns on
• For earth ground, the ground fault LED turns off
• For the battery charger, the battery charger fault LED turns off
• For battery voltage, the battery fault LED turns off
• For the data bus to peripheral consoles, the data bus fault LED turns off
The following will occur on the main control board for more specific indication when the specific fault restores.
• For the speaker volume control, the speaker volume control fault LED(s) turns off
• For the amplifier over current, the amplifier over current fault LED turns off and all associated speaker circuit fault LEDs turn
off
• For the option cards (NFC-XRM-70V, NFC-BDA-25/70V, NFC-CE6) the option card missing LED turns off
The following actions will occur on the NFC-BDA-25/70V optional amplifier for more specific indication when the condition restores.
• For over current, the over current LED turns off
4.4.15 External Audio Input Operation
The external audio input (aux. audio) located on the display board terminal TB5 can serve as any one of the following:
• A background music input
• A message recording input from an audio source
• A general paging input from a paging microphone or telephone system
• A night ring input from a telephone system
The function of the external audio input must be selected in programming. Refer to "External Audio Input" on page 61. For external
audio input electrical requirements, "Input/Output Circuit Specifications" on page 13.
When programmed, background music will play on all NFC-50/100 speaker circuits only when the audio system is in a normal, standby
condition. During alarm or alert operation of the audio system, background music is suspended. Background music is also suspended
during an AC power loss condition to preserve the batteries. Speaker circuits on the main NFC-50/100 panel are fully supervised while
background music is playing. Speaker circuits on the NFC-50DA or NFC-125DA distributed amplifiers are not supervised while playing
background music.
For programming messages using the external audio input, refer to "Recording Custom Messages" on page 61.
When programmed, the external audio input may be used for general paging or night ring operation. The building's "Private Branch
Exchange (PBX)" telephone system or a third party microphone system must provide the audio signal along with a contact closure to
trigger the paging or night ring. Paging or night ring will occur only when the audio system is in a normal, standby condition. During
alarm or alert operation of the audio system, paging or night ring is suspended. All speaker circuits are fully supervised during paging or
night ring operation. Refer to "Input/Output Circuit Specifications" on page 13 for night ring electrical requirements. Refer to "Night
Ring" on page 30 for wiring requirements.
