The LEM-1DL master station provides communication to and from a door station, and h\
as a separate button 
for door release. This supplemental instruction manual addresses many of the additional fu\
nctions and 
modifications for the LEM-1DL system, including installation and troubleshooting information.

Pg. 2 WIRING DIAGRAM: Dual Master LEM-1DL System with DAK-2S Dual Master Adaptor
OPERATION NOTES:
1.  Only one master can be used at a time.
2.  If both masters are activated, a feedback (squeal) will be heard t\
hrough 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. 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 co\
lored wire end of the component modules at both masters. (The component          
     modules will easily fit within the space available.)
6.  Connect the “E” terminal between the door station and master s\
tations.
7.  If door release is included, use a separate 2-conductor wire from th\
e “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 to \
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.
IMPORTANT!!!
Each master  REQUIRES an individual power supply.

SYSTEM CONFIGURATION: 
LEM-1DL with Door Release contact activating a Normally Closed relay for a Mage\
ntic Lock
Note:  For applications requiring a Normally Closed (N/C) contact (Ma\
gnetic 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 i\
ntercom 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.

PROBLEM POSSIBLE CAUSESOLUTION
No call tone from door to master station. (A) OFF button on master not pressed.
(B) E/- jumper not attached.(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/C, LE-SS/A 
subs).  Wire from E/- should be connected to E of master.
No communication from door station. E/- jumper not attachedEnsure that the jumper at the door station is attached between 
E and - terminals
No call tone, no communication.  Chirping 
sound when volume control is turned all the 
way up. Wrong voltage on LEM-1DLCheck power supply.  If it’s a model SKK-620B, remove and 
replace with model PT-1210N.  Verify that voltage on +/- 
terminals is between 12-16V AC or 12-24V DC.
In system with RY-AC/A and external signaling 
device connected, the external device is 
activated every time TALK button is pressed. DAK-2S component module missing or 
installed incorrectly.Make sure the component module is installed with the bare 
wire under the 1 terminal and the white wire of the RY-AC/A 
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. Missing DAK-2S dual master adaptor 
kit.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.
In a dual master system, feedback occurs 
when pressing the talk button. One power supply is used for both 
masters.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.
AC noise when listening to the door station Intercom wiring run close to AC wiring.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.
AC noise when talking to the door station Power wires run with communication 
wires.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.
