2. FEATURE DESCRIPTIONS

2.1. START COMMANDS

There is a total of 6 START inputs available. Each START

COMMAND requires a momentary (250 ms minimum)

contact closure for the program to recognize the

command. The commands will be stored in a first-in, first-

out(FIFO) manner. Multiple closures, after the first

recognition of the command, will be executed in order as

they were recognized by FIFO after the completion of the

first command. If the command is "latched" ON the

message will repeat until the contact closure is removed.

2.2. STOP/RESET COMMAND

A momentary (250 ms minimum) contact stops

(terminates) the message that is playing. All messages in

FIFO will be aborted. All active inputs have to be

reactivated for normal operation. (See SUPERVISION for

additional use.)

2.3. TEST COMMAND

When TEST COMMAND is maintained for at least 250 ms

before the START #1 COMMAND is provided, the built-in

test message is played. The TEST COMMAND must be

maintained until the playing cycle is complete or the

ERROR/FAIL relay will indicate a malfunction. Thus, the

TEST feature may be used to play the built-in test

message for a check of the entire public address system

or to TEST the unit's ERROR/FAIL function.

2.4. BUILT-IN TEST MESSAGE

The TEST MESSAGE is stored within the program

EPROM which is a basic part of the PD-006 board

circuitry.

The test message says, "This is an audio system test".
