8-1-1 Signal Input

There are two kinds of signal inputs, bit input and binary input.

The difference in a signal input is explained below.

(1) Bit Input

• Theshort-circuitingofthesignallinesCH1throughCH4tothecommonlinewillplaybackMP3

data.

SignallinesCH1toCH4correspondstomessageNumbers1to4,respectively.

• Amaximumof4messagechannelscanbeplayedback.(Whenthesoundreductionfunctionis

active, a maximum of 3 message channels can be played back)

• Whentwoormoreinputsaresimultaneouslyentered,theinputischoseninaccordanceto

priority, in which the higher number is of higher priority.

In the memory playback mode, the memory saves the input based on the priority of the higher

number.

Whenthesoundreductionfunctionisactivated,theCH4signallineturnsintothesound

reduction signal line.

Refertopg14“7-2.SoundReductionFunction”.

• Refer to the corresponding playback mode for a detailed explanation of the time chart.

(2) Binary Input

• Theshort-circuitingofthesignallinesCH1throughCH4tothe common line will playback MP3

data.

refertopg.25“10.BinaryInputTable”

• Amaximumof15messagechannelscanbeplayedback.(Whenthesoundreductionfunctionis

active, a maximum of 7 message channels can be played back)

• Whenthesoundreductionfunctionisactivated,theCH4signallineturnsintothesound

reduction signal line.

Refertopg.14“7-2.SoundReductionFunction”

• Refer to the corresponding playback mode for a detailed explanation of the time chart.

The order of input priority is from right to left:

CH4 > CH3 > CH2 > CH1

CH1

CH2

An input-off state of 100 ms or more is considered as a logic “0”.

A triggered input of 100 ms or more is considered as a logic “1”.

CH1

CH2

An input-off state of 100 ms or more is considered as a logic “0” .

A triggered input of 100 ms or more is considered as a logic “1”.

Make sure the binary input is more than 8ms.
