The LEKTROLOK Models 103 and 104RA Deadbolt Electric 
Locks are compact units designed to fit narrow stile doors.  Both 
models come complete with keepers (deadbolt holes) which 
make it simple to install on all types of doors or windows includ-
ing single, pairs, double acting or overhead, either in-swinging or 
out-swinging.  When the lock is aligned with the keeper, the 
deadbolt projects into the keeper thus locking the door.  The 
deadbolt is retracted (and the door unlocked) by means of a re-
mote switch, a key switch, time programmer or other electrical 
contact which interrupts the power.  Both models are ideally 
suited to programmed locking and unlocking of laundromats, 
lobby doors, or other unattended areas.  Use of a lighted push 
button switch at the door (Alarm Lock Model 191) assures that people inside the building can exit after Iock-up time; the door 
will relock automatically after exit.  May be wired with smoke 
detectors and/or fire alarm systems for automatic unlocking in a 
fire emergency. 
 
MODELS AVAILABLE 
Model 103 is a standard fail safe unit which projects the dead-
bolt only while power is on.  When the power is off, the dead-
bolt retracts.  Model 104RA (Reverse Action) unlike the stan-
dard unit is fail secure and will project the deadbolt only when 
the power is off.  When the power is on, the deadbolt re-
tracts.

Note:  
The deadbolt will not project unless the magnet is opposite the reed switch.  The template supplied 
serves the majority of installations.  If your installation is different, always maintain a 1/8” gap between the face of the 
lock and the keeper.  The lock should be mounted on the door frame (rather than the door) for ease of wiring.  If in-
stalling the lock with the plunger facing down, see special installation instructions on the next page.   
 
Before mounting the lock, provide for the electric wires to the lock.  After the lock and keeper are installed, place the 
magnet onto the keeper slot which faces the reed switch in the lock as shown in figure 1.  After the magnet is in 
place, affix the aluminum plate into the keeper recess.

WHEN INSTALLING THE LOCK WITH PLUNGER FACING DOWN 
 
When installing the lock in a vertical position with the plunger facing down, we suggest replacing the colored spring (7 
coils) with a stronger one (not colored, 5 coils) included in the box.  To replace the spring, refer to the diagram below and 
replace it as follows: 
 
1.   Remove the lock cover. 
 
2.   Remove the screws holding the solenoid to the base. 
 
3.   Slide the solenoid out of the base. 
 
4.   Remove the colored spring (7 coils) and replace it with the spring (not colored, 5 coils) included in the box. 
 
5.   Slide the solenoid back into the base. 
 
6.   Fasten and tighten the screws holding the solenoid to the base. 
 
7.   Fasten the lock cover.
