WIRING

Lay out your system in advance. Determine the exact location of each station, and make a

sketch showing the number of wires required from each station to the other stations. Assign station numbers at this time.

Refer to the chart below and select the proper wire gauge to meet your specific distance

requirements.

Begin your installation with master station All masters included in your system should be

connected and tested before beginning substation installation. Note the position of the (C) terminal on each master station, and be sure that each station is wired correctly.

After installing your second station, we recommend the power supply be connected and a test

be made of all functions, calling and talking between each station. Unplug the power supply before making any additional connections.

WALL MOUNTING INSTALLATION

1) Attach mounting bracket to wall

or box with supplied screws.

2) Mount station on bracket.

TERMINAL BOX INSTALLATION

1) Remove screw and cover as

shown.

1) Remove the 4 mounting screws on bottom of the master as shown in Fig. 1, and lift the plastic case

from the base.

2) Using a nipper or soldering iron, remove the jumpers between A & G, I & J, and K & L on the

printed circuit board as shown in Fig. 2.

3) Make a hole in the body of the base to pass the wires thru using a soldering iron, '/4" or 8mm drill as shown in Fig. 3. If a soldering iron is used, clean away the burned plastic with a sharp knife as shown in Fig. 4.

4) Route the wires into the base and mount the handset with screws provided as shown in Fig. 5.

5) Solder the 12 wires from the handset to the printed circuit board as shown in Fig. 6. Be sure the wires are in the correct order.

6) Replace the plastic case and reinstall the mounting screws.

WIRING DIAGRAM #1

The following diagram illustrates an intermixed LAP system. All stations connected to the BG-IAC/PG-KC will receive all-call announcements and BGM. Substations must be connected to the BG-IAC/PG-KC thru a 15 mfd bipolar capacitor as shown (if BGM/all-call is desired), or the system

will not work.

NOTE: Remove the shorting link attached to the (E) and ( —)

terminals on all substations as shown if your system uses 2 or more masters. In this case, 2 common and 1 individual wire per sub are required.

WIRING DIAGRAM #2

The diagram below illustrates a typical single master system with an NP-B Call-in button, AH-

108 Horn Speaker, and an LT-1 Matching Transformer installed. In operation, the horn speaker will

function just like a standard substation.

LAF-20

NOTE: If your system consists of just I master and several

subs, only 2 wires per sub to the master are required. Leave the (E) and ( —) terminals on all subs shorted together. Also, make a jumper and short the (E) and ( —) terminals on the master station terminal box as

L+’ V + ’<'1

shown.

OPERATION

MASTER STATION

★ Illuminated Occupied light indicates another master is using the system. Make your call once the

light has gone out.

★ Placing a call;

1) Depress the selector button for the desired

station.

2) To call by tone, momentarily press both PRI

VACY and TALK buttons. To call by voice, depress the TALK button and speak.

3) Depress the TALK button to speak, release to listen. If using LAR-2 handset, use the

Call by voice j

TALK switch in the handset to control conversation.

4) Upon completing conversation, press the

OFF button and release the depressed selec tor button(s) by pressing any other selector button half way down.

-6-

NOTE: The LAF-20/20S master station must be placed on standby after each conversation by press

ing the OFF button and releasing any depressed selector switch button(s) as described, or the

system will not work.

★ Receiving a call from another master;

1) If your station is in a non-privacy mode, no action is

necessary; communication is hands-free.

2) If the PRIVACY button is depressed, release it by momentarily pressing the TALK button, then resume hands-free operation. Reply can be made privately by using the LAR-2 handset, if installed.

PRIVACY button pops up by momentarily depressing TALK button.

NOTE: There is no LED annunciation between masters except the Occupied light.

★ Receiving a call from a substation:

1) An incoming call is annunciated by both tone and light. Depress the selector button above the

lighted annunciator light.

2) Press the TALK button to speak, and release to listen.

3) Upon completing conversation, press the OFF button and release the depressed selector button(s) by pressing any other selector button halfway down.

4) If privacy is desired, depress and lock the PRIVACY button down.

NOTE: When receiving a call from a master station and substation simultaneously, reply first to the

master. Then, after the Occupied light has gone out, depress the selector button above the lighted annunciator light and communicate. DO NOT DEPRESS THE SELECTOR BUT TON WHILE THE OCCUPIED LIGHT IS ILLUMINATED.

★ Operating electric door release (LAE-20S only);

Door release mechanism is activated by pressing and holding the door release button until the door is opened by someone.

★ All-call announcement (LAF-20S only);

1) If the Occupied light is not on, depress and lock the ALL-CALL button down. A pre-tone will

sound at all stations connected to the BG-IAC/PG-KC, and BGM will he cut off automatically.

2) Make announcement while pressing and holding the TALK button.

3) After making announcement, release the ALL-CALL button by pressing it again.

NOTE 1: DO NOT MAKE ALL-CALL ANNOUNCEMENT WHILE THE OCCUPIED LIGHT

IS ON.

NOTE 2: All-call announcement cannot be made thru the LAR-2 handset.

★ Distributing Background Music (BGM);

1) Turn on the ON/OFF switch for music on the BG-IAC as well as the BGM source/amplifier. BGM

will be distributed to the selected stations until interrupted automatically during communication.

2) When BGM is not desired, turn off the ON/OFF switch on the BG-IAC.

NOTE: A low volume call tone from a substation may be announced at all masters while BGM is

being distributed. Only the annunciator light on the called master will light, and will time out normally in about 20 seconds.

SUBSTATION ★ LA-A, LA-D & LA-AN;

1) Momentarily press the call button to call the master. If a tone is heard, wait for the master to

answer. When the master replies, communication is hands-free.

2) If no call tone is heard when the call button is pressed, the system is occupied. Try again later.

★ LA-A3 & LA-AN3;

1) Momentarily press the call button for the desired master (unlock the PRIVACY button first on the

LA-AN3). When the master replies, communication is hands-free.

2) If no call tone is heard when the call button is pressed, the system is occupied. Try again later.
