AMTEL DIRECT-LINE SYSTEM
GROUP POWER SUPPLY / DEDICATED CABLE

INSTALLATION INSTRUCTIONS
For assistance, please call Amtel Technical Support at (800) 999-8903
8:30 AM - 5:30 PM Eastern Time

Use these instructions to install an Amtel Direct-Line system using one or more central group power supplies and a dedicated cable.

BEFORE BEGINNING INSTALLATION:
Discuss the placement of each unit with the system administrator. Carefully plan the location of each group power supply, keyboard, panel, and wallmount unit to be installed. A power plug from the group supply controls the power to the system; therefore the group supply must be located within five feet of the electrical outlet to be used. The outlet must be kept clear for easy access.

Check with local building codes for compliance.

*Amtel requires that each unit be wired in a "HOME-RUN" configuration; each unit to have a dedicated cable coming from the Group Power Supply

Check with the appropriate person as to which configuration to use.

Units are shipped non-programmed or programmed:

NON-PROGRAMMED - if the units are shipped without programming, when power is applied to the system, the units boot up with factory default settings and displays: "SET ADDRESS ? ?".
PROGRAMMED - if the units are shipped programmed, there will be a label on the front of the
the unit(s) indicating the address of the unit. When power is applied to the system, the units boot up and display the "date and time". Be sure to install the units in the respective locations indicated by the address label. *Save the address labels for future reference.

COMPONENTS:
The Amtel Direct-Line system consists of the following components:

GROUP POWER SUPPLY
One group power supply for every 10 units utilizing group power after 2017. For existing units, if the Power Supply Unit within the GPS requires replacement, an additional GPS or Keyboard Power/Data adapters (PT# 930-0130) may be required.

A wiring schematic is located on the inside front cover of the power supply.

INSTALLATION INSTRUCTIONS:

Group Power Supply

1. Locate the power supply within 5 feet of an 110VAC outlet.
2. Remove the front cover from the group power supply.
3. Mount the power supply securely to the wall. Location temperature should not exceed 90 degrees Fahrenheit.
4. Pull wire to each unit location.
5. Connect the colored wires to like-colored terminals inside the group power supply.
6. When connecting 2 or more power supplies
inter-connect only the green and white terminals (green to green / white to white)

DO NOT INTER-CONNECT THE RED-BLACK TERMINALS.

7. Connect the units (instructions below). If the units are pre-programmed there will be a label indicating the address and location of each unit. Carefully ensure that each unit is installed in its proper location.

Important: Keep the labels attached to the units after installation. They will be used later when the system is tested for proper installation.

Keyboard and/or Panel Units
1. Wire the wall plates to the cable, matching color-to-color.
2. Install the wall plates.
3. Connect cable from wall plate to back of keyboard/panel.

Wall mounted Units - surface mounted
1. Remove the 4 screws from sides of wallmount unit.
2. Remove back cover.
3. Using wall anchors and screws as needed, install the back plate.
4. Connect the pigtail to the cable, matching color-to-color.
5. Connect pigtail to the four pin male connector located at bottom left of wallmount.
6. Secure wallmount to back plate.

Wall mounted Units - flush mounted

Note: The wall must be cut out to allow a wallmount to be recessed. Flush mounted units have a pre-installed bezel.

1. Connect the pigtail to the cable, matching color-to-color.
2. Remove the 4 screws from sides of wallmount unit.
3. Remove back cover.
4. Connect pigtail to the four pin male connector located at bottom left of wall mount.
5. Secure back plate to wall mounted panel.
6. Secure bezel to wall using 4 screws.
7. Connect group power supply to 110V outlet.

CHECKING THE SYSTEM:
The following steps outline a simple test to check the wiring and to ensure proper installation of the Amtel Direct-Line System. Physically check that each unit is powered up (display screens are on). If the displays are blank see the power supply section of "Problem solving".

Determining programming status:

Programmed units display the date and time.
Non-programmed units display the message "SET ADDRESS ??".

If the units are programmed:

1. A unit's screen displays the date and time.
2. Record the addresses that are indicated on the labels that you previously saved.
3. Go to section "Checking the system from a keyboard unit.

If the units are not programmed:

1. A unit's screen displays "SET ADDRESS ??".
2. An address must be entered. An address consists of two characters, alpha, numeric, or a combination. For example, Room 2 would have the address R2, the Front Desk would be FD, and so on. Check with the appropriate person for assistance in assigning addresses.

Assigning an address for a Keyboard unit.

1. Type the address then press SEND.

Assigning an address for a Wallmount or Panel unit.

1. Press CHOICE 1 or to assign the 1st character.
2. Press CHOICE 2 to move to the next space.
3. CHOICE 1 or to assign the 2nd character.
4. Press SEND AS ALERT to save the address.

Record the addresses that are indicated on the labels that you previously saved.
Once the units are programmed, and the list of addresses are recorded, you are ready to perform the system check.

Checking the system from a keyboard unit:

1. Press the ALERT ENTER key, (the "N" key).
2. Type the first address on the address list. (Be careful if using the letter "O", and not confusing it with the numeral 0).
3. Press the SEND key.
4. Type the word "TEST".
5. Press the SEND key. Note the keyboard's screen. If the screen returns the date and time, the alert was successfully sent.
6. Repeat steps 1 through 6 to test the remaining units.

If the error message COMM ERROR (SEE USER GUIDE) is flashing, a unit is not programmed correctly, or the wiring is incorrect. If an address was entered incorrectly the error message COMM ERROR (SEE USER GUIDE) will flash momentarily and then display the address of the faulty unit with the text "TEST". Press the spacebar to get the cursor and re-enter the correct address.

If the display still flashes check the wiring.

Go to problem solving section of this guide.

Problem solving:

This section will assist you in solving a communication problem if the system test fails.

Go to the unit whose address is displayed after the COMM ERROR (SEE USER GUIDE) error message.

CHECK THE ADDRESS FOR ACCURACY.

At a keyboard unit
1. Press the SET UP key, (the period (.) key) then press the 6 key. The programmed address is displayed.
2. If the address is correct, press CLEAR.
3. If the address needs to be changed, type the correct two character address.
4. Press SEND.
At a panel or wallmount Unit
1. Press and hold CLEAR and CHOICE 1 . The programmed address is displayed.
2. If the address is correct, press CLEAR.
3. If the address needs to be changed, Press CHOICE 1 or to assign the 1st character. Then press CHOICE 2 to move to the next space. Again press CHOICE 1 or to assign the 2nd character. Press SEND to save the address.

CHECKING THE GROUP POWER SUPPLY
The group power supply can only be checked with a digital voltmeter. Other meters may load the data lines providing erroneous readings.

1. The power for the individual units is supplied via the group power supply on the RED and BLACK terminals. The voltage should be 24 volts DC with red being positive and black being negative. If the voltage is low or non-existent, remove the power cord from the wall and disconnect the red wire that runs between the Power One module and the terminal block. Plug the AC power cord into the wall outlet and measure the voltage between the removed red wire and the black terminal strip. If the voltage is 24 volts DC, go to step 2 otherwise we need to check the wall outlet for power. There are two ways to quickly check a wall plug for power:

a. Place the meter in the volts AC position and measure the outlet for approximately 115 volts AC.
b. Take a known 115-volt device (ie: a fan or drill motor that is working elsewhere) and plug it into the outlet and test for performance. If this doesn't work, the outlet is defective.

2. Place an OHM Meter across the RED and BLACK terminals, the RED and WHITE terminals, RED and GREEN terminals, BLACK and WHITE terminals, BLACK and GREEN terminals, and the WHITE and GREEN terminals while looking for a low reading (under 1 meg ohm). To determine which cable is defective, remove wires, one at a time, from one of the pair of terminals identified with the low reading previously. As soon as the reading goes high, the last wire removed will indicate the bad cable. Repair or replace the cable and restore all disconnected wires.
