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 oniy the specified
power source onterminals.
★ 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:
• High 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: (However, 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 LEF model
Install a surge-arrester
(discharging voltage: 100-180V)
at a point close to the output,
taken to earth ground.

■ 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
Wire number
LEF-3
9 conductors
#822210 in USA
LEF-5
12 conductors
#822212 in USA
LEF-10
17 conductors
#822220 in USA
LEF-10S
20 conductors
#822220 in USA
LE Subs
3 conductors
#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 8d paging zones, each of which requires one
designated wire.
■ Power suppiy
Entire LEF system can be powered by one PS-12C (or PS-12A) power supply, located near the center of the trunkage 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.

i LEF system Troubleshooting Guide
\
Problem
Solution
Single-master
system
1. No call tone or LED when sub calls
master (2-wire connection).
Make sure jumper is installed between E and - at the subs and the master
station.
2. Call tone works, but no
communication, or communication
works, but no call tone.
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.
Mulit-master
system
3. Master stations cannot call each
other.
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 master 1
connects to the “1” teminal of all other masters.)
4. Cali tone is too loud or too soft.
Adjust call tone volume with slide switch located under faceplate. (Use small
screwdriver.)
