General

The FireVoice-25/50 (NFV-25/50) is a state-of-the-art, single-

or dual-circuit (25 watts each) Emergency Voice Evacuation

Control Panel (EVAC). The NFV-25/50 records five field-pro-

grammable messages (up to 60 seconds total message dura-

tion) with an integral commercial-grade emergency

communications microphone or from an external audio source.

Significant technological enhancements set the NFV-25/50

apart from other EVAC panels — these include full supervision

in both active (alarm or music) and standby conditions, super-

vision of amplifier outputs, field wiring, message generator, all

tone generators, and the microphone. The integral power sup-

ply charges up to 18 AH batteries, which can be housed in the

NFV-25/50 cabinet.

The NFV-25/50 is suitable for use as an adjunct (slave or

stand-alone) to most UL-Listed Fire Alarm Control Panels

(FACPs). An optional 25 watt, 25 VRMS audio amplifier is

available for system expansion to 50 watts (providing dual 25-

watt speaker circuits) or as a secondary amplifier in jurisdic-

tions requiring backup. A 70.7 VRMS converter is also avail-

able for independently converting amplifiers to meet retrofit

needs.

A host of field-programming options, including the capability of

five custom messages (fire, tornado, evacuation, hazmat, non-

fire, multi-language, etc.) make the NFV-25/50 the most versa-

tile voice evacuation system available.

Suitable Applications include schools, auditoriums, dormito-

ries, theatres, restaurants, places of worship, lodging, office

buildings, and factories.

Standard 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 acti-

vation by an FACP.

• Two command input circuits can be independently field-pro-

grammed 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 infi-

nite 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 indepen-

dently 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.

TWO SPEAKER CIRCUITS Dual output zone, dual input circuit — tone/voice message (SEE FIGURE 2). This application example has of one NFV25/50 with two speaker circuits and requires the installation of a second amplifier. This configuration is suitable for small facilities requiring no more than 50 watts of output power and a 60second fire evacuation message. The addressable FACP directs tone or voice messages to either of the speaker circuits via the control modules connected to the CMD1 and CMD2 inputs.
