Important Trouble Shooting Tips
NOTE: In order to ensure proper catch and release of the latchbolt,
the 8500 electric strike requires that the opening be plumb and square .

Door sag and latchbolt wear are two common conditions that
may prevent an electric strike from working properly. Here are
some quick tips to ensure the HES 8500 performs at its best:
Poorly constructed, worn or damaged latchbolts may not
interact properly with the ramp of an electric strike.
Check the condition of your latchbolt by lightly pressing the tip
of the latchbolt at a 45 degree angle to the door face. (See Figure 1).
The latchbolt should be pushed easily into the door.
If abnormal resistance is encountered, apply a lubricant to the
inside of the latchbolt opening while pressing the latchbolt .
(See Figure 2). If this does not correct the friction,
additional maintenance on the latchbolt may be required.
Note: Check with the latchbolt manufacturer regarding
proper latchbolt maintenance and approved lubricants.
Most doors experience some sagging over time. To check for
door sag, look at the location of the lock’s deadlatch in relation
to the 8500’s deadlatch platform. The deadlatch should rest
on the deadlatch platform. If the deadlatch contacts the faceplate
or the edge of the 8500’s body, the latchbolt may not be fully
released when the strike is activated causing the door not to be
released.
To correct this condition, remove the 8500 and cut material
from the bottom edge of the frame opening and possibly the
mounting tabs (Note: make sure to sure to retain the mounting
hole). This allows the 8500 to be shifted down slightly in the frame.
Reinstall the 8500, using the SD faceplate instead of the standard
faceplate.
If this does not correct the issue, additional maintenance on the
door may be necessary.
Lubrication of the 8500 electric strike is not necessary.
