Notifier

The Notifier First Command (NFC) is a single channel, emergency voice evacuation panel that may be used for fire applications, mass notification applications, or both.

Overview

The Notifier First Command (NFC) is a single channel, emergency voice evacuation panel that may be used for fire applications, mass notification applications, or both. The NFC-50/100 comes standard with one speaker circuit. The panel provides the ability to record fourteen field programmable messages (up to 60 seconds each) with an integral microphone or from an external audio source. An integral power supply with battery charger supplies operational power. A 50 watt audio amplifier is built into each panel. An optional second 50 watt amplifier is also available for backup purposes or to provide an additional 50 watts. The backup amplifier is available in either 25 volts or 70 volts depending on which application is necessary. Two Command Input Circuits can be independently field programmed for activation by an FACP Notification Appliance Circuit reverse polarity or by closure of a supervised normally open contact and six Command Input Circuits activate on contact closure. CMD 1 and CMD 2 provide terminals for NAC input and output to allow installation of the audio panel anywhere along the NAC circuit being used to activate it. If the message generator fails, the system automatically reverts to a backup tone generator. Power is fed independently to each amplifier so that a short circuit in one amplifier will not shut down the other. Full output power of 50 watts per amplifier is generated while in a low battery condition. Power is not diminished when the optional 70 VRMS transformer module is installed. Audio is amplified utilizing modern integrated circuits as opposed to transformer technology. This provides for very low signal distortion for crystal clear audio. Primary applications for the audio panels include protecting structures such as military facilities, restaurants, schools, auditoriums, places of worship, building with occupancies over 50, etc. The NFC-50/100 is designed to interface directly to addressable or conventional (CMD inputs 1-8) fire alarm control panels or can be used with the NFC-50/125DA panel to distribute audio in systems that require more than 100 watts.
