Fire Exit Hardware
is to be installed on
Fire Doors bearing
the marking “Fire
Door to be equipped
with Fire Exit
Hardware” Any
retrofit or other field
modification to a Fire
Rated opening can
potentially impact the
Fire Rating of the
opening.
IMPORTANT:
• Use supplied templates for field installations.
• Use door preparation documents for door/frame manufacturing.
• Door must be properly reinforced where the exit device chassis and latches
are mounted. The surface must be flush and flat within 1/16" (1.5 mm).
• Prepare the interior of the door using the exit device template or door
preparation and instructions.
• Prepare the exterior of door using the trim template or door preparation and
installation instructions.
• All threaded holes require a minimum material thickness of 0.125" (3 mm).
• We recommend samples be used to verify preparation before mass door or
frame manufacturing.
• NOT RESPONSIBLE for any physical or property damage due to incorrect /
improper preparation or installation.
FOR DOOR PREPARATION
REFERENCE ONLY.
Verify that this is the latest version of
this document. We recommend
samples be used to verify preparation
before door / frame manufacturing.

appropriate trim using instructions and hardware supplied with the
trim and the exit device.
3. If no trim is used and the exit device is surface mounted on the
door, used supplied mounting hardware as indicated on pages 2,
3, and 4.
4. Fire exit devices must be installed with through-bolts when
installed without a trim.
If a 5/8" diameter hole

1. Pushing on push bar will retract the latchbolt and
allow the door to open. Latchbolt will stay
retracted, if not adjust the screw on top of the
retractor with a screw driver.
2. Once the door is closed the strike will engage with the deadlock, which
will allow the latchbolt to engage inside the strike. The latchbolt cannot
be retracted when the door is closed. If not, adjust the strike position to
engage with the device deadlock.
