FEATURES

• * BG-10C adaptor provides three functions for your LEF or LEF-C communication system.
  • 1. All-call announcement from any LEF-C Room master Station(& LEF-10S, surface-mount and LEF-1C sub master station)
• 2. Music distribution (all-call & music can be received at all masters & LEF-1C, LE-C, CN subs)
• 3. Chime distribution for door station call-in

INSTALLATION GUIDELINES

For installation of LEF-C intercom & MY video systems, refer to Instructions for LEF-C & BGR-10A. According to the system configuration, make wiring diagram between BG-10C and the first LEF-C station.

* BG-10C works with only 2-wired PanTilt MY video system.

Coax-cabled camera adaptors MFW-P1 and MFW-P3B cannot be used with BG-10C.

* Power supply;

Use one PS-12F power supply for an entire LEF-C and BG-10C adaptor.

On BG-10C, connect +,- wires from PS-12F to DCIN +,- terminals, then extend power supply wires +,- to LEF-C network.

* Selector switches;

On BG-10C unit, 11 selector switches are provided to turn on/off music & chime tone for each LEF-C Room Station. After completing all the wirings, check if all MUSIC & CHIME selector switches are set properly.

* Music input voltage to AUX;

Rated input voltage to AUX terminal should not exceed 1V. If surpassed, it could cause sound distortion, intermittent transmission or unit failure.

* Do not open the case;

Do not open the case while BG-10C is powered. Some components inside the unit are warm while operational.

* Surface temperature;

During operation, it is possible that BG-10C's housing surface temperature could be warm to the touch. This a normal occurrence.

* Incorrect wiring;

Strictly observe the wiring polarity. Never connect PS-12F +,— power supply wires to any other terminals than DCIN +,— on BG-10C. If PS-12F +,— wires are wrongly connected to 1 $\backslash sim$ 11 and E, or to P2 and P3 on BG-10C, it could cause system disorder and severe damage to BG-10C. If +,— wires on BG-10C would be connected to No.(1 $\backslash sim$ 10) terminals on LEF-C unit, it could cause damage to LEF-C unit.

* Door station calling;

If a door station calls in while a unit is in the all-call mode, the chime will be heard through all of the stations, regardless of the position of each music/chime on/off switch.

* Installation locations;

Select the installation locations that would not be exposed to temperature/humidity extremes, water, oil, dust, iron dust, inflammable and chemical products, etc.

It is suggested that BG-10C unit and wiring be kept more than 2m(7') away from a radio, etc., as it may pick up chime call tone.

MOUNTING GUIDELINES

Attach the mounting bracket with the two screws B (supplied) on back of chassis.

Fasten the two screws A(supplied) on the wall, with a space of 220 mm( 8-5/8"), protruding approximately 10 mm( 3/8") from the wall. Hook the BG-10C unit onto the screws and pull the unit downward until it locks in place. Pass wires through cable clamp. Connect wires on terminal section. Fix the mounting bracket with the wood screw C. Attach terminal cover.

NOTES;

• 1 Max. 3 door stations can be connected to BG-10C & LEF-10C network.
• 2 Use LEF-C No. terminal for each door station;

DA - 10 for door #1 DB - 9 for door #2 DC - 8 for door #3

3 Connect to as many LEF-C room master stations as required(limited only by system capacity) for door station chime call-in(Chime is heard only when BG-10C is used).

3. Music Speaker Connection

LE-C, CN sub station has C terminal, to be connected to BG-10C for music & all-call reception. If a remote speaker is installed for music reception at an LE-C/CN sub station, extend two wires from S, E terminals to remote speaker. (communication and all call are still received through LE-C/CN speaker)

BG-10C OPERATIONAL SETTINGS ;

For music distribution;

1 Put MUSIC switch to ON position. Turn on power of music source. Music is distributed through all of the connected LEF masters, LEF-1C sub master and LE-C/CN subs speakers. If music is not required at a particular station(s), set the MUSIC/CHIME selector switch to OFF or CHIME only position.

• 2) Music mutes automatically during station-to-staiton communication or All call.
• 3 Put MUSIC switch to OFF position to cut off music throughout the system.

For all call;

Initiate all call at one LEF-C master station or at LEF-1C sub master station. Depress ALL CALL switch, which produces pre-tone through all of LEF masters, LEF-1C & LE-C/CN subs. Send message while depressing and holding TALK button. Depress ALL CALL switch, and the switch is released. (on LEF-1C only, press and keep pressing ALL CALL switch to send message)

Turn control clockwise to increase each volume, treble and bass.

• * Do not initiate all call or any other operation, while Occupied LED is lit.
