L909X-Series Electrified Mortise Lock,
LM929X-Series Electrified Two-Point Lock
Wiring Instructions and Specifications
L-Series Electrified Lock
All installations should be in accordance with local electrical codes and national electrical code, NFPA 70.
L909X-Series and LM929X-
Series electrified locks offer
selection between one of
two modes, EL or EU.
Select the appropriate mode
for the installation using the
mode select switch located
on the mortise chassis.
EL, electrically locked
(fail safe):
Outside knob/lever or both
outside and inside knobs/
levers (depending on
function) will lock when
power is applied. In the
event of power failure, the
opening will be unlocked.
EU, electrically unlocked
(fail secure):
Outside knob/lever or both
outside and inside knobs/
levers (depending on
function) will unlock when
power is applied. In the
event of power failure, the
opening will be locked.
Note: When mode is switched (from EL to EU or EU to EL) the lock requires a complete lock/unlock power cycle to synchronize to
the proper mode.
IMPORTANT! Connection of L-Series electrified mortise locks to a supply circuit containing electromagnetic devices (i.e., solenoid based) is not
recommended. If used, the resulting transient voltages could damage the lock. The transient voltage must be carefully suppressed at the equipment
producing it before connecting the lock to the same circuit. A varistor rated at 35 V (peak recurrent) may be used for transient voltage protection.
Troubleshooting
If lock does not operate.
• Ensure the lock is powered with DC power. Do not use AC power.
• Ensure the input voltage is between 10.8 and 26.4 volts DC.
L-Series Request-to-Exit (RX) Lock
RX utilizes a microswitch inside the lock case to detect rotation of the inside knob/lever. The switch then signals the use of the opening to the security system.
The RX is a removable module located on the bottom edge of the lock chassis. The module must be properly positioned to detect inside knob/lever
rotation. If not properly positioned, the lock and/or microswitch may be damaged.
Note: RX is not applicable with LM929X-Series locks.
RX module installation
1. The microswitch must be on the same side of the door as the
handing screw (facing the inside of the door).
2. Install the RX switch module as shown.
Change lock handing with RX
1. If the RX module is installed, remove the RX module.
2. Remove the handing screw.
3. Rotate the latch 180° (if necessary).
4. Reinstall the handing screw on the appropriate side.
5. Reinstall the RX module with the microswitch on the same side as
the handing screw.

Switch
L9091/93/95, L9493/95 and LM9291/93/95 functions lock both inside and
outside levers. Locking both levers will prevent normal egress from the
inside and will prevent the intended operation of an emergency exit.
