Frequently Asked Questions - 8400 Dormakaba

How do I determine the correct rod length for my door?

Measure the door height from finished floor to top of door. Refer to the table in step 1.8 of the manual: for example, a 7'0" door requires a top rod length of 36-1/4". For bottom rod, use the same table but measure from floor to bottom of door.

Can I install this exit device on a fire door?

Yes, but for less bottom rod devices on fire rated doors, an additional popper must be used. Refer to the instruction sheet packed with the popper. Also ensure the door is properly fitted and hung before installation.

How do I reverse the hand of the exit device?

Remove the actuator pin and bracket, rotate the chassis 180 degrees, reinstall actuator and pin-bracket in the top hole, rotate the cam on rear of chassis 180 degrees, move screw to lower hole, and reinstall retaining rings. Follow step 1.3 of the manual.

What is cylinder dogging and how do I use it?

Cylinder dogging allows you to retract the latches and hold them open with a key. To enable: thread a mortise cylinder into the touch bar assembly, tighten the set screw, depress the touch bar, and turn key clockwise to dog (hold) or counter-clockwise to release.

What tools and drill sizes are needed for installation?

You need a drill with bits: No. 25 drill for wood doors (1" deep), No. 14 drill for tapping metal doors (12-24 tap), 3/8" diam. drill for sex bolts through door, and No. 30 drill for rod guide screws. Also have a Phillips screwdriver and Allen wrench.

How do I adjust the latch bolts to be flush?

After installing rods, hold top rod upward and depress touch bar. Rotate the rod right (clockwise) to shorten or left to lengthen until the latch bolt aligns. For bottom rod, lift up and adjust similarly until the bottom of latch bolt is flush across the cover. Refer to steps 1.9.6-1.9.8.

Can I use an outside trim with this device?

Yes, the device supports outside trim with rim cylinder or lever trim. For rim cylinder, trim the tailpiece 1/8" to 3/16" less than inside face of door. For lever trim, see additional instructions in trim carton.

What is the recommended horizontal reference line height?

The manual recommends a horizontal reference line on the push side of the door at 40-5/16" (1024 mm) from the finished floor. This is for standard installations. Adjust if needed.

How do I install the rod guides?

After cutting rods to length (do not cut threaded end), use the drill jig provided to redrill holes. Secure rod guides over rods at equal distance between top and bottom latches and chassis. Use No. 30 drill for #8 x 2" screws.

What should I do if the touch bar does not operate smoothly?

Check that all components are aligned correctly: verify that the horizontal center line is maintained during installation, ensure rods are properly adjusted, and that the chassis is level. Lubricate moving parts with a light oil if necessary. If problems persist, consult manual or contact support.

1.1 Overall

1.2 Door preparation

NOTE: SURFACE OF DOOR WHERE EXIT DEVICE IS TO BE INSTALLED MUST BE FLAT. PROPER REINFORCEMENT OF DOOR IS ALSO REQUIRED.

NOTE: BEFORE STARTING INSTALLATION:

1. DOOR SHOULD BE FITTED AND HUNG.
2. VERIFY DOOR WIDTH WITH BOX LABEL FOR CORRECT LENGTH.

1.2.1 Measure and mark horizontal reference line on push size of door. (40-5/16" [1024] from finished floor, recommended.)

For less bottom rod devices delete bottom latch installation steps.

Less bottom ord devices should not be used where security is a primary concern.

1.2.2 Measure and mark the vertical reference line (center line of chassis) on push side of door. (See dimension below.)

1.3 Prepare strike

For exit only device with no outside trim function

1.3.1 Remove (2) phillips head screws.
1.3.2 Then remove cam bracket assembly.
1.3.3 No additional prep required except for mounting holes. (See spotting template)
1.3.4 Proceed to step 1.4.

For device using outside trim with rim cylinder

1.3.1 Tailpiece should be trimmed 1/8" [3] to 3/16" [5] less than inside face of door.

For device using outside lever trim

1.3.1 See additional instructions packaged in trim carton

For hand reversal:

1.3.1 Remove actuator pin
1.3.2 Remove pin-bracket
1.3.3 Remove actuator
1.3.4 Rotate chassis 180 degrees

1.3.5 Reinstall actuator & pin-bracket in top hole of bracket
1.3.6 Reinsert actuator pin in actuator
1.3.7 Rotate cam on rear of chassis 180 degree
1.3.8 Move screw to lower hole
1.3.9 Reinstall all retaining rings on pins

1.4 Drill door for exit device

1.4.1 Refer to carton label for model and trim numbers before drilling.
1.4.2 Prepare door by using the template enclosed (tape to door).
1.4.3 Horizontal center line and center line of chassis (vertical reference) on template MUST be on horizontal and vertical reference line on door.

CAUTION: If horizontal center line is not maintained, vertical rods will not fit.

NOTE: Vertical reference line is not centerline of cylinder

1.5.1 If no cutting is required; proceed to step 1.6.
1.5.2 If cutting is required, determine length by:
- measuring "A" (hinge side door stop to center of chassis), subtract 2" [51] to determine "B" (length of touch bar and rail dim.).

Centerline of chassis (vertical reference line)

1.5.3 Mark length on rail (cut with touch bar depressed, packing block rotated on edge), then remove packing block and any burrs.

* Depress touch bar to cut to length

1.6 Install chassis, exit device and trim

Install chassis to touch bar; install exit device and any trim using screws as noted on the spotting template.

1.6.1 Level touch bar/chassis assembly on door, hold mounting plate against touch bar, mark (2) holes and drill.
• No. 25 drill 1" [25] deep for wood doors.
• No. 14 drill 12-24 tap for metal doors.
- 3/8" [10] diam. drill through door for sex bolts
1.6.2 Fasten mounting plate (against rail) to door with (2) round head phillips screws.
