Introduction - Notifier AVL-1 Operation And Installation Manual

Introduction

Notifier's VoiceLink products provide unique digital recording, programming, storage, and playback capabilities to create versatile
and automated announcement systems. Figure 1 illustrates the basic capabilities of the AVL-1.
The AVL-1 can record voice, tones, and other sounds. The AVL-1 can then playback the recorded voice, tones, and other sounds
through amplification equipment (not supplied with the AVL-1) when instructed to do so by a contact closure or an instruction over a
serial link from other equipment. The AVL-1 may also be used for programming message files into a Series AVL-EM.
This manual describes the AVL-1 which features:
•
Up to 16 minutes of audio storage in volatile PSRAM (see "PSRAM" definition in glossary) memory integrated circuits
("IC's") and a memory retention battery to power the memory IC's during power failure conditions.
•
Selective activation of up to 8 message files using contact closures or open collector transistor switching (expandable
to 256 message files using optional AVL-EM's).
•
Selective activation of up to 999 message files through the serial port.
•
Keypad and menu driven LCD display with password protection.
•
Field upgradable.
•
Record using microphone or high impedance input.
•
Up to 5 levels of message file priority assignments with the two least significant priority levels being acknowledgeable.
•
Up to 4 audio output channels.
•
Supervision of input lines and many internal operations with trouble diagnosis and notification.
•
Serial communication supervision and optional verification of serial commands with a trouble indication if an error is
detected.
•
An optional telephone interface.
•
An RS-232 interface and an optional RS-485.
A AVL-1 MUST BE PROPERLY INSTALLED, PROGRAMMED AND CONNECTED TO A COMPATIBLE CONTROL PANEL AND
AUDIO SYSTEM, AND A POWER SUPPLY, TO FUNCTION IN A VOICE ANNOUNCEMENT SYSTEM. THE AVL-1 OPERATES
ONLY WITH REGULATED AND FILTERED DC VOLTAGE, NOT FULL-WAVE-RECTIFIED VOLTAGE.
The control panel can range from simple push-buttons or detectors that provide contact closures to activate AVL-1 files to
sophisticated, computer-based control panels that address AVL-1 files through a serial port. Similarly, the audio system can range
from a simple amplified speaker to a large, multi-channel audio distribution system that may also be integrated with a zoned
telephone paging system. Notifier offers a wide line of audio equipment to configure such systems.
Wheelock models; DV-100, DV-200, MDV-2, DX-100, DX-200, MDX-2 and DV-EM are UL 864 approved for use with Fire Alarm
Control Panels (FACP). The above models are used as accessory control units in UL 864 listed protective signaling systems. All
models have an operating voltage range of 11.0-29.0VDC. All are operated by a serial port or contact closure with an adjustable
output from 0.5-2.0VRMS.
WARNING: THE AVL-1 IS NOT A LISTED UL 864 PROTECTIVE SIGNALING SYSTEM. THE AVL-1 DOES NOT PROVIDE
SUPERVISION OF ITS OUTPUT CIRCUITS.
PROTECTIVE SIGNALING SYSTEM.
