Notifier NFV-25/50

Features

• Listed to UL Standard 864, 9th edition.
• Integral 25 watt, 25 VRMS audio amplifier with single Style Z (Class A) or Style Y (Class B) speaker circuit (expandable to 50 watts using the ACC-AAM25).
• Modular design for maximum system flexibility and ease of service.
• Five Command Input Circuits (CMD) are available for activation by an FACP.
• Two command input circuits can be independently field-programmed for activation by a Notification Appliance Circuit (NAC) or contact closure.
• Three command input circuits activate on contact closure.
• Manual deactivation of speaker zones.
• Command inputs allow: – One 60-second message. – Two 30-second messages. – Three 20-second messages. – Four 15-second messages. – Five 12-second messages.
• Microphone time-out feature.
• Nineteen different system and diagnostic LEDs.
• Two Form-C trouble relays (System & AC Power Loss).
• Optional equipment: second amplifier; local playback speaker; and remote microphone.
• Integral digital message generator with standard, factory prerecorded emergency evacuation message.
• Custom messages are field recordable, using the integral microphone or the audio input jack.
• Digital message may be field-selected for 3, 4, 6, 8, or infinite repeat.
• Built-in alert tone generators with steady, slow whoop, high/ low, or chime tone capability.
• Field-selectable lead-in/trailing tone selection.
• Alert tone selection may be field-programmed to conform with ANSI S3.41 Audible Emergency Evacuation Signal (Temporal Pattern), per NFPA.
• Speaker zone control via CMD inputs or keypad.
• Dual-optically-isolated, trigger input circuits are independently field-programmable for activation by polarity reversal (host FACP NAC) or dry-contact closure.
• Zone 1 switch-programmable for All-Call operation.
• Integral diagnostic LEDs include: Power, System Trouble, Microphone Trouble, Message Generator Trouble, Tone Generator Trouble, Amplifier Fault, and others.
• Independent Form-C trouble relay allows FACP to monitor voice system while in active (alarm) state.
• Integral piezo provides local audible indication for troubles.
• Fully supervised in Standby and Active states, including integral microphone, amplifier output, message generator, speaker wiring, and tone generators.
• Independent amplifier supervision: current limit, audio level, short circuit protection.
• All outputs are power-limited.
• Auxiliary power output provides local power for addressable control modules when used to activate the NFV-25/50.
• Compatible with all NOTIFIER FACPs, as well as other manufacturers’ panels.
• Background music capability (requires AHJ approval).
• When using the background music option, total output power per amplifier is reduced to 20 watts.
