MS-704/RM-704 FOUR-CHANNEL MAIN/REMOTE

2-12

INTERNAL OPTION JUMPERS

There are several jumper options inside the chassis of the MS-704 and

RM-704.

CAUTION:Remove AC power from the unit before removing the top cover.

The following options are available:

• IFB operation mode select

• Run/test mode jumper

• Program audio feed to announce output

IFB Mode

The MS-704 and RM-704 support two different modes of operation for the

internally generated IFB function. J10 on the main PC board (in the lower left

hand corner of the board just behind the DIP switches) selects this mode. If an

interrupt enable DIP switch is enabled for a channel, the operation will be as

follows:

• LOCAL (Talk Function Activated): Jumper between Pins #1 and #2,

factory default. When a talk is active on the channel on which the

interrupt has been enabled, the program will be interrupted for the

duration of the talk.

• REMOTE (Call Signal Activated): Jumper between pins #2 and #3.

When a call is received on the channel on which the interrupt has been

enabled, the program will be interrupted for the duration of the call signal

on that channel. To cause an interrupt of the program from this station a

call signal must be sent by pressing the call button or enabling the

auto-call DIP switch option for that channel and activating a talk on that

channel.

Run/Test Mode Jumper

The J2, J12, P3, and P4 jumpers on the main printed circuit board allow a

factory test mode to be invoked and should never be used for normal intercom

operation.

CAUTION:Do not move these jumpers. Moving these test jumpers may

cause the MS-704 and RM-704 not to operate. Possible damage

to the product may result.

Program Audio Feed to Announce Output Jumper

J11 on the main board allows program audio to be fed to the announce output.

This is selected by setting jumper J11 to the on position. In this mode,

pressing the announce pushbutton turns off the program audio feed to the

announce output and replaces it with audio from the selected panel or headset

microphone.

The factory default position for J11 is in the off position, blocking program

audio feed from the announce output.
