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).
(B) Make sure jumper is attached to E/- terminals on door
(A) OFF button on master not pressed. station (or proper wires jumpered on LS-NVP, LE-SS subs).
No call tone from door to master station.
No communication from door station.
(B) E/- jumper not attached.
Wire from E/- should be connected to E of master.
Ensure that the jumper at the door station is attached between
E and - terminals
E/- jumper not attached
No call tone, no communication. Chirping
sound when volume control is turned all the
way up.
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.
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.
Make sure the component module is installed with the bare
DAK-2S component module missing or wire under the 1 terminal and the white wire of the RY-AC
installed incorrectly.
spliced to the colored wire.
In a dual master system, call tone is heard
at the second master when pushing the talk
button on one master.
Install 1 component module from the DAK-2S at each master.
See Pg. 2. If DAK-2S is not available, connect specified diode
and capacitor in parallel and install as shown on PG. 3.
Missing DAK-2S dual master adaptor
kit.
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.
In a dual master system, feedback occurs
when pressing the talk button.
One power supply is used for both
masters.
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
