Installation Directions
CAUTION! Before connecting any device at the installation site, verify input voltage using a multimeter. Many power
supplies and low voltage transformers operate at higher levels than listed. Any input voltage exceeding 10% of the
solenoid rating may cause severe damage to the unit and will void the warranty.

Evaluate Opening
1. Verify opening is plumb and square and evaluate latch
bolt condition. For important details, see “Troubleshooting
Tips” on page 3.
Prepare Strike
2. The electric strike ships in fail secure mode. If you need
to convert the unit to fail safe, see Diagram 2 on page 5.
Please note that operation in fail safe mode removes the
fire rating of the electric strike.
Prepare Frame
3. Remove dustbox and prepare door jamb per the
template detail on page 6. Be sure to allow enough room
behind the electric strike in the cut out to avoid pinching
the wires.
Install Deadlatch Platform
4. Select correct option. Determine platform position
appropriate for the lockset (see Diagram 4 on page 5).
5. Insert deadlatch platform into the keeper slot as shown
in Diagram 5 on page 5, ensuring that the screw holes in
the deadlatch platform foot and outer casing are aligned.
It may be necessary to slightly retract the keeper in order
to properly seat the deadlatch platform fastening foot.
6. Fasten the deadlatch platform to the electric strike using
the #4-40 screw provided.
Install Strike in Frame
7. Select and electrically connect the appropriate 12 or 24
Volt pigtail to match system power as illustrated in
Diagram 1 below. For 12V AC/DC or 16V AC, the pigtail
marked “12 VDC” should be used. For 24V AC/DC, the
pigtail marked “24 VDC” should be used. If no connector
is present, configure the wires as shown in Diagram 1.
8. If using Latchbolt Monitor (LBM) or Latchbolt Strike
Monitor (LBSM), see Diagram 3 on page 5.
9. Connect the 12 or 24 Volt pigtail to the electric strike.
10. Insert electric strike in jamb cutout and install the
appropriate faceplate using the #12-24 screws provided.
Partially tighten screws and close the door.
11. Verify lockset’s deadlatch is positioned on top of the
deadlatch platform, and does not touch the faceplate. See
troubleshooting tips for more information.
Set Horizontal Adjustment
12. Open the door and pull the electric strike flush with
the inside face of the frame (in the direction of the
opening), and tighten screws.
13. Close the door. If excessive movement (door play) or
preload exists when latched, remove strike from the jamb
cutout, and add one or two of the horizontal lockdown
shims to the front face of the electric strike (See Diagram
6 on page 6). Ensure the horizontal lockdown shim is
making contact with the inside face of the frame. Check
again and add or remove additional shims until proper
horizontal adjustment is achieved.

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

Figure 3: Door Sag Adjustment
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. To check
the condition of your latchbolt, lightly depress the tip of the
latchbolt at a 45 degree angle to the door face -- (see Figure 1).
The latchbolt should be easily pushed into the door. If
abnormal resistance is encountered, apply a lubricant to the
inside of the latchbolt opening with the latchbolt depressed.
(See Figure 2) Check manufacturer for proper maintenance
and approved lubricants. If this does not correct the friction,
additional maintenance on the latchbolt may be required.
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 fully
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.
