LEM-1DL Supplemental Instructions
Single Master Station with Door Release
- 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 button
for door release. This supplemental instruction manual addresses many of the additional functions and
modications 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 rst 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. NOTE: Connect power leads to master BEFORE plugging in power supply
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 t 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-12S 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. Contact rating is 30V AC/DC @ 1 Amp.
PT-1210N
IMPORTANT!!!
Each master REQUIRES an individual power supply.

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 specications 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, uorescent 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 rst 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
No call tone from door to master station.
No communication from door station.
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 TALK button is pressed.
In a dual master system, call tone is heard
at the second master when pushing the talk
button on one master.
In a dual master system, feedback occurs
when pressing the talk button.
AC noise when listening to the door station
AC noise when talking to the door station
POSSIBLE CAUSE
(A) OFF button on master not pressed.
(B) E/- jumper not attached.
E/- jumper not attached
DAK-2S component module missing or
installed incorrectly.
Missing DAK-2S dual master adaptor
kit.
One power supply is used for both
masters.
Intercom wiring run close to AC wiring.
Power wires run with communication
wires.
SOLUTION
(A) Press OFF button on master. If call tone still doesn’t come
through, read solution (B).
(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 a model SKK-620, remove and
replace with model PT-1210N. Verify that voltage on +/terminals 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 the DAK-2S at each master.
See Pg. 2. If DAK-2S is not available, connect specied 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” from any AC
electircal 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 jacket cable with the communication wires run
to the door.
