Form 39990 Rev. E
09/23/2005
TROUBLE SHOOTING:
Some common problems associated with the installation of the 390 series can be easily recognized and corrected:
Problem:
Possible Solution:
Lock has power but won’t lock.
Fire alarm not connected or open connection. SW4-7 not ON (set switch,
LED (on lock) is Green.
remove and re-apply power).
Won’t go into delayed egress.
Check dipswitch settings (p.9). Armature washers not installed properly (p.5)
Magnet not properly aligned with armature. (p.6)
Goes into delayed egress upon powerup.
Armature washers not installed properly (p.5)
Improper gap between magnet and armature (p.6)
Lock can be pushed open with minimal resistance.
Magnet/Armature/washers not installed properly (p.5-6).
Lock “hums” or vibrates noisily when energized.
Magnet/Armature/washers not installed properly (p.5-6).
Lock “beeps” every several seconds.
Low voltage alert. Check voltage at terminals 1&2. It must be 12.00 volts or
24.00 volts or slightly higher.
Won’t accept iButtons.
iButton reader on cover not plugged in to board. (p.15)
LED(s) flash once quickly.
Relock delay set to 0 sec.(p.14)
Lock won’t accept programmed codes/iButtons.
Relock time delay set to 0 sec. (p.14)
LED(s) flash once quickly.
Keypad not initialized (p.12).
MBS doesn’t change state when locked.
Low voltage. Mechanical misalignment. Debris between lock and armature.
Armature/magnet not installed properly (p.5-6).
DSM/SEC option not working properly.
Armature holder not aligned with DSM/SEC switch(s). Switch not
plugged into correct jack (p.8)
MAINTENANCE
It is not recommended that the magnet be painted (unless ordered with in iridite primer). If the unit must be painted, it
is important that the mating surfaces of the magnet and armature not be painted. The iButton reader and LED must
not be painted either. The electromagnet and armature are plated for corrosion resistance and require little mainte-
nance. For maximum performance the following service should be done to both the armature and electromagnet as
required: Clean the mating surfaces of the electromagnet and armature with a non-abrasive cleaning pad, apply a light
coating of silicon lubricant and wipe with a clean dry cloth.

ERROR CODES:
If an error is made while manually programming a lock, an error code indication will be indicated at the iButton reader
or keypad. The LED(s) will flash several times. Count the number of flashes and refer to the chart below for diagnosis.
