- REFER TO INSTALLATION MANUAL INSIDE LEM-1DL BOX FOR STANDARD
INSTALLATION INFORMATION -
The LEM-1DL master station provides communication to and from a door station, and has a separate
ton for door release. This supplemental instruction manual addresses many of the additional functions
but
and
modifications for the LEM-1DL system, including installation and troubleshooting information.

OPERATION NOTES:
1. Only one master can be used at a time.
2. If both masters are activated, a feedback (squeal) will be heard through the system when either TALK button is pressed.
3. If feedback occurs, press the OFF button on one of the LEM-1DL masters.
INSTALLATION GUIDELINES:
1. Use 2 conductor shielded wire from the door station to the first master, then to the second master.
2. Install the units at the desired locations.
3. Separate PT-1210N power supplies are required for each master station.
4. Install the bare wire leg of the component module directly onto the "1" terminal of the LEM-1DL's.
5. Attach the wire coming form the "1" terminal of the LE-D to the colored wire end of the component modules at both masters. (The component modules
will easily fit within the space available.)
6. Connect the "E" terminals between the door station and master stations.
7. If door release is included, use a separate 2-conductor wire from the "EL" terminals of the masters through an AC transformer and to the door strike.
8. The EL-9S is designed for a standard wood framed door, and for light and medium usage. If a different type of door is used, install a strike appropriate
for the door.
9. The door release button on the master station is a "Normally Open" contact closure.

Diode: 1N 4148

SYSTEM CONFIGURATION:
LEM-1DL with Door Release contact activating a Normally Closed relay for a Magentic Lock
Note: For applications requiring a Normally Closed (N/C) contact (Magnetic locks, etc.), an external
relay should be chosen based on the lock’s power source.
When using a 12-18V DC magnetic lock, Aiphone’s RY-18L relay may be used.
For 24V DC magnetic locks, Aiphone’s RY-24L relay may be used.
A 3rd party relay of similar specifications may also be used. Refer to manufacturer’s
documentation for connection details.

INSTALLATION TIPS:
1. Use shielded wire for the communication path, and ground one end of the shield to an earth ground.
2. Run intercom wire at least 20" away from AC wiring, fluorescent lights or dimmer switches.
3. Keep intercom cable away from alarm, data, phone, and video cables.
4. Door release wires must be in a separately jacketed cable from the intercom wires. Use two separate
cables; one for audio and one for door release.
5. When installing a second master station, wire must be run from the first master station, not from the
door station. See diagram on page 2.
6. Do not install master station near light switches, dimmer switches, or other devices that may cause
interference with the intercom system.
7. Do not install the master station on the opposite wall from the door station. If the units are too close,
acoustical feedback may result.
TROUBLESHOOTING GUIDE:
PROBLEM POSSIBLE CAUSE SOLUTION
(A) Press OFF button on master. If call tone still doesn't come through,
read solution (B).
No call tone from door to master station.
No communication from door station. E/- jumper not attached
No call tone, no communication. Chirping sound
when volume control is turned all the way up. Wrong voltage on LEM-1DL.
In a system with RY-AC and external signaling
device connected, the external device is activated
every time the TALK button is pressed.
In a dual master system, call tone is heard at the
second master when pushing the talk switch on one
master. Missing DAK-2S dual master adaptor kit
In a dual master system, feedback occurs when
pressing the talk button. One power supply is used for both masters.
AC noise when listening to the door station. Intercom wiring run close to AC wiring.
AC noise when talking to the door station. Power wires run with communication wires
(A) OFF button on master not pressed.
(B) E/- jumper not attached
DAK-2S component module missing or
installed incorrectly.
(B) Make sure jumper is attached to E/- terminals on door station (or
proper wires jumpered on LS-NVP, LE-SS subs). Wire from E/- should be
connected to E of master.
Ensure that the jumper at the door station is attached between E and terminals.
Check power supply. If it's model SKK-620, remove and replace with
model PT-1210N. Verify that voltage on +/- terminals of LEM-1DL is
between 12-16V AC or 12-24V DC.
Make sure the component module is installed with the bare wire under
the 1 terminal, and the WHITE wire of the RY-AC spliced to the colored
wire.
Install 1 component module from DAK-2S at each master. See
instructions on Pg. 3. If DAK-2S is not available, connect specified diode
and capacitor in parallel and install as shown on Pg. 3.
Ensure that each master has its own power supply. Use any power
supply with output between 12-16V AC or 12-24V DC. Aiphone
recommends the PT-1210N.
Ensure that the intercom wire is run at least 20" away from any AC
electrical wire, or crossed at 90 degrees. Intercom wire should be
shielded, with the drain wire connected to an earth ground at the master
end.
Ensure that power wires coming from the PT-1210N are not run in the
same jacketed cable with the communication wires run to the door.
