PRECAUTIONS ON INSTALLATION & WIRING

A CAUTION

★ Do not connect AC wires to any terminal on any unit, as fire or unit damage may occur. Connect only the specified

power source on +, - terminals. ★ Do not install more than one power supply (PS-12C or PS-12F or PS-12A) for an entire LEF system. ★ Do not attempt to install or connect wires on LEF equipment while system’s power supply is plugged in. ★ LEF masters and related equipment, except door station, are designed for indoor use only. Do not install outdoors.

IMPORTANT

★ There is no need to disassemble the equipment for installation, other than to open the unit to connect the wires to the

back case. Do not access the PC board or components unless properly qualified. ★ Any other manufacturer’s products installed with this system (power supply, external signalling device, etc.) are not

covered under Aiphone’s warranty. ★ Do not mount LEF equipment in the following places, as it may cause the system to malfunction:

• Fligh or extreme cold temperature areas: under direct sunlight, near equipment that varies in temperature, in front of air conditioner, inside a refrigerated area, etc.

• Places subject to moisture or humidity extremes.

• Places subject to environmental conditions, such as dust, oil, chemicals, salt, etc.

★ LEF units are electronic devices, which must not be subjected to water or any other liquid.

★ Severe weather conditions, such as lightning storms, may cause damage to LEF equipment.

We recommend that power surge protection be installed as follows: (Flowever, this does not guarantee that no damage will occur).

• If the power supply has a GROUND terminal, take it to an earth ground. In this case, a separate surge arrester is not necessary.

• When using a power supply that has no GROUND terminal, install a surge arrester near the output as shown.

• Additional SA-1 surge arresters can be installed to protect communication lines. One SA-1 per 2 wires on master station.

PS-12A or PS-12C

_ Surge-

Install a surge-arrester (discharging voltage: 100-180V) at a point close to the output, taken to earth ground.

Before actually installing the LEF system, the contents on pages 4-8 must be thoroughly read and understood.

■ LEF all-master configurations

LEF all-master systems are designed to be wired in a looped fashion from the first to last master. Number of conductors for a full system (not including “K” terminals) are:

Model Cable LEF-3 9 conductors LEF-5

LEF-10

12 conductors 17 conductors #822220 in USA

LEF-10S 20 conductors

LE Subs 3 conductors

Wire number #822210 in USA #822212 in USA

#822220 in USA

#822203 or #821803 in USA

• Single-master system can be wired with 2 conductors homerun from each sub. (Wire #822202 or #821802 in USA)

■ Cable requirements

Use multi-conductor cable with an overall shield, non-twisted, 22AWG to 18AWG (0.65mm to 1.0mm), to accommodate the maximum number of LEF master stations, LE subs, audio or PanTilt door(s), or 8i2 paging zones, each of which requires one designated wire.

■ Power supply

Entire LEF system can be powered by one PS-12C (or PS-12A) power supply, located near the center of the truckage cable. For a system including All-Call, Chime, & Music with the BG-10C, use a PS-12F power supply (12V DC, 2.5A) to power the entire system.

master (2-wire connection).

2. Call tone works, but no communication, or communication works, but no call tone.

3. Master stations cannot call each other.

4. Cali tone is too loud or too soft.

Make sure jumper is installed between E and - at the subs and the master station.

Same as #1, E & - jumper must be in place. If 3 wires are used, 1 & - are for call-in, and 1 & E are for communication. Check continuity and connection of wires.

The “C” terminal of the master means “CALL”, and allows master-to-master communication. Make sure the “C” terminal of each master is connected to a designated # terminal on all other masters, (example: C at ma.ster 1 connects to the “1” teminal of all other masters.)

Adjust call tone volume with slide switch located under faceplate. (Use small screwdriver.)

Solution

5. LED lights don’t light up when calling master-to-master.

Problem Solution

Station LEDs only light when a sub station calls. A responding master answers handsfree, therefore not having to select a station number.

6. Occupied light is always on.

7. Call tone and LED from subs work fine, but no communication, or vice versa.

8. When sub calls in, multiple LED lights come on.

9. Door release doesn’t work.

10. All Cali from LEF-1 OS doesn’t work.

11. Chime from door station doesn’t

work.

12. Chime from door works, but electronic call tone in LEE masters also is heard.

Make sure all masters are in the OFF (standby) position. The station whose LED above the OFF button is lit is the one that’s on. Check “R” wire for a short to ground. Take R wire off of unit. If Occupied light remains lit, the unit is damaged and needs repair.

Check E and - wires from sub for proper connection to master. See # 2 solution above.

Make sure station number wires are not shorted together. F^emove all jumpers between E & -, Test master station by taking wires off of affected station #’s, then touch a jumper wire between a station number and negative. If multiple LEDs light up, the unit has sustained power surge damage and must be sent in for repair.

RY-PA relay is required for each door to be released. Connect black wires to L & -. For selective door release, connect RY-PA between K#(matching station # that door is on) and L, L which provides 12V DC when “key” button is pressed.

All Call requires the BG-10C Adaptor with PS-12F power supply.

BG-10C must be installed. Wire from door station must connect to BG-10C, “1” of door to DA/DB/DC of BG-10C. Neg. (-) must be connected from LEF to BG-10C.

Door station should be wired directly to BG-10C or first master. Make sure the A/B switch on the back of the LEF master is in the “A” position. Make sure “R” line is connected between LEF master and BG-10C.

13. All Call doesn’t work, but BG-10C is included In system.

14. All Call pretone and voice volume are too loud or too soft.

15. When an All Cali is initiated, all of the LEDs corresponding to sub station channels light up.

16. Feedback is heard between

intercom stations in adjacent rooms.

17. Communication to another station is very weak.

18. LEF system has AC hum when

listening to another station trom a master station.

Check connection from PI, P2, P3 terminals from LEF-1 OS to BG-10C. PI should be 10V DC or higher when All Call button is engaged. P2 and P3 carry the voice signal from the initiating master to the BG-10C. Be sure to press TALK while making an All Cali announcement, and press All Call button when finished.

Adjust volume levels on front panel of BG-10C.

Make sure jumpers between E & - are removed. When using the BG-10C for All Call in a system with sub stations, a non polarized capacitor (NP-25V) must be installed in series on each station # line that a sub staiton is on between the BG-10C and LEF-1 OS.

Intercom stations should not be mounted back to back on the same wall. If they are, they must be installed at least two feet, 60cm apart with insulation

isolating them. Adjust voice volume control downward to eliminate feedback.

Adjust “Voice Vol.” upward. Make sure the “1 and terminals from sub to master are not reversed.

System wiring must be run at least 20”, 50cm away from AC wiring, fluorescent lights, or dimmer switches. Wires can cross AC at 90 degrees. If shielded wire was used, tie all of the shields together and ground one end to an earth ground. If noise persists, isolate source of the noise and separate the intercom from the source.

TECHNICAL PRECAUTIONS----------------------------------------------------------------------

IMPORTANT:

• Aiphone Corporation is not responsible for improper installations of ifs producf which result in interference generated by dimmer switches, fluorescent lighting fixtures or other similar electrical devices. Any such installation must be corrected at the source by the installing party. Aiphone also recommends that when installing any of its communication products that the intercom wiring be run at least 20 inches (50 cm) away from any AC wiring.

• In LEF/MY video system, run a separate LEF audio cable and MY video cable. Using the same cable for both audio and video systems will cause severe interference with the LEF audio communications.

• Clean your LEF equipment with a soft cloth dampened with neutral household cleanser. Never use any abrasive cleaner or cloth.
