3 PRECAUTIONS ON INSTALLATION & WIRING

• ★ Do not attempt to install or connect wires on MC-60/4 equipment while system's power supply is turned on.
• ★ MC-60/4 masters and related equipment are designed for indoor use only. Do not install outdoors.
• ★ Do not connect any other power source than specified on terminals 1/+ and 5/-. Doing so can damage the MC-60/4 equipment.
• ★ Do not open any MC-60/4 system components. Ask qualified personnel.
• ★ All the products of other manufacturers, power supply, buzzer, etc. used for MC-60/4 are not within our warranty, and must be used under manufacturer or distributor's specifications and warranty.
• ★ Do not mount MC-60/4 equipment in the following places, as it may cause the system to malfunction:
  • High or extreme cold temperature areas: under direct sunlight, near equipment that varies in temperature, near an air-conditioner, inside refrigerating warehouse, etc.
  • Places subject to moisture or humidity extremes.
  • Places subject to environmental conditions, such as dust, oil and chemicals, etc.
• ★ MC-60/4 is an electrical appliance, which must not be subjected to water and or any other liquid.
• ★ Weather conditions, such as lightning storms, may cause damage to MC-60/4 equipment. It is suggested to take protective measures as follows;
  • When a DC power supply is used: On the power supply with grounding terminal, be sure to take the terminal to earth ground. In this case, it is not necessary to connect a surge-arrester.
  • If no grounding terminal is available, install the SA-1 surge arrester on the power supply line.
• Before MC-60/4 is actually installed, the contents of this Manual must be thoroughly read and understood.

MOUNTING

Mounting guidelines

The MC-60/4A is designed for wall or pedestal mounting only.

• 1. Loosen screw on the bottom of the front case, and remove the unit by sliding the front case upward from the back chassis, then pull away. Disconnect the intercom from the back chassis by unplugging the multi-pin connector. Do not force the unit open. (Set the intercom unit aside while making wire terminations so as not to mar or scratch the unit.)
• 2. Install the back chassis to a single gang box or mounting ring, or directly to the wall.
• 3. All wiring terminations are done on the back chassis directly onto the screw terminal section. Designate a color code for wire numbers 1-7, and connect wires accordingly. Connect all like terminals together with matching wires.
• 4. Wiring is done in a daisy-chained method with up to 10 stations on a run.
• 5. When wiring is completed, reattach the intercom to the back chassis by plugging in the multi-pin connector. Align from the top and slide downward into position. Tighten screw at the bottom of the front case.

MC-60/4B

★ Install terminal box and cable in non-trapping manner.

6 OPERATIONS

When an LED at the top of the station is lit, that channel is in use. Select another channel that is not in use. When any one station has a channel selected, the corresponding LED will be lit on all other stations. If responding to a call, select the station number that was requested by the person paging.

Calling

Select the channel number (1-4). Page & request a person to join in on a selected channel. Release

PAGE button and wait for reply.

When being paged

Go to the nearest MC-60/4 station, and select the channel you were requested on.

Conference calling

Call for up to 2 persons to a conference call on your selected channel. If more than 3 people join in,

communication volume may be affected.

• Music muting

When a station starts paging, pretone will sound and the music will be muted. When the page is completed.

the music will return.

★ Firmly depress channel number button in every operation.

7 TECHNICAL PRECAUTIONS

★ Make wiring blocks in a manner that wiring length of any two blocks added together does not exceed 1,700' w/ 22AWG either.

Fig.1 System w/ single block

• ★ The MC-60/4 is rated to operate at temperatures between 0°C ~ +40°C (32°F ~ 104°F).
• ★ Clean the MC-60/4 equipment with a soft cloth dampened with neutral household cleanser. Never use any abrasive cleaner or cloth.
