CHAPTER 1 Introduction Description The MS-4002 is a complete 4-channel master station and system power supply (24 VDC, up to 3.5Amps total power) in a single unit. Simply plug it into any AC power outlet from 100 to 240 volts, add a microphone or headset, connect intercom stations to the backpanel, and it’s ready to communicate. It has 1-, 2-, 3- and 4-channel connectors, so a separate breakout panel is not needed to mix multiple intercom stations.

CHAPTER 2 Installation Direct Program Listen Enable/Disable By default, each MS-4002 program input can be heard locally by all intercom stations. Program input routing to the intercom channels can be turned on or off via the MS-4002 front panel programming. For more information on programming, see “Standard Programming” on page 21 and “Advanced Programming Using the MS-4002” on page 22. Mounting The MS-4002 mounts in a standard 19-inch equipment rack and is 1 RU (Rack Unit) high.
External Program Input and PA Output Connections for external program input and PA output are shown in Figure 1, EMS-4001 Expansion Station Connection (optional component). REFERENCE:Refer to the EMS-4001 User Instruction Manual (p/n 93507713000) for detailed connection information.

Sidetone Adjustment The MS-4002 uses full-duplex audio (the same as a conventional telephone line) in which the talk and listen audio are sent and received on the same line. When you talk on a channel, you hear your own voice in the speaker or headphones. This is called sidetone. If you are using the MS-4002 with a microphone and speaker, sidetone could cause unwanted feedback, since the microphone may pick up your returned voice audio and re-amplify it.
If you are using headphones that completely enclose the ears, adjust sidetones as follows: 1. Tap the Headset key to turn the headset microphone on. 2. Tap the channel 1 Talk key to turn it on. 3. While speaking into the microphone, use a small flat-bladed screwdriver to adjust the channel 1 Talk key to turn it so you hear your voice at an acceptable level in the headphones. 4. Tap the channel 1 Talk key to turn it off when finished. 5.
CHAPTER 3 Operation Operation NOTE: A quick-reference to the following operating features are shown in Table 5. Normal vs. Programming vs. Advanced Programming Mode The MS-4002 has three operating modes: normal operating mode, standard programming mode (see page 21), and advance programming mode (see page 22). In normal operating mode, the Mic Kill key will be unlit, and in programming mode it is lit continuously.
Volume Adjustment If you are using a headset, adjust the intercom listen level with the left volume control on the front panel of the MS-4002. If you are using a speaker, adjust the intercom listen level with the right volume control next to the speaker. External speakers requires their own volume controls. Receiving Calls 1. When there is an incoming call signal on a channel, the Call key for that channel flashes red.
All Talk You can talk to all intercom stations that currently have their listen keys activated. This applies to all channels of the MS-4002, as well as all the talk channels of any EMS-4001 Expansion Stations. To use the all talk function, do the following: NOTE: If you are using manual microphone activation instead of Vox, make sure the proper microphone switch is turned on (either Headset or Panel Mic). 1. Press and hold the All Talk key while talking. 2. Release the All Talk key when finished.
Using Mic Kill If the Mic Kill feature has been enabled, you can use it to deactivate all talk keys on a single channel or on all channels. This feature is useful when a remote talk key has been left ON and is causing unwanted noise on a channel. To use Mic Kill, do the following: 1. Tap the Mic Kill key. It blinks green. 2. Tap the Talk or Listen key for a channel to turn off all talk keys on that channel. Or, tap the All Talk key to turn off all talk keys.
