Instructions for Installing AD-8400, MD-8400 & 12-MD-8400
Series Concealed Vertical Rod Exit Device
Verify that the correct exit device is being installed on the correct door. Function, finish and
size should all be verified. Note: Before removing door from hinges, determine the gap
between top of door and frame. Determine smallest gap between bottom of door and
high point of floor or threshold as door swings. This information is needed for step #7.
Remove door from the frame.
1) Drill, tap & c’sink the door per template, except
for the (2) #10-24 (4A) on the hinge side.
2) Screw top bolt & rod assembly (A) and bottom bolt & rod
assembly (D) into inner chassis (B).
3) Slide complete assembly into top of door.
4) Attach inner chassis (B) to door with screw (EE) using
hole (3A).
Note: If 700 Series ET Control is being used, it must be
installed at this point, prior to step 5. See appropriate
instructions.
5) Position chassis (C) over fillister head screw (EE) and attach
to inner chassis (B) using hole (5A) with washer (JJ) &
screw (HH). Do not tighten yet.
6) Secure top of chassis (C) to door with screw (FF) using
tapped hole (2A). Do not tighten yet. Use chassis (C) to
retract top bolt & rod assy (A) & bottom bolt & rod assy (D)
to adjust bolt projection.
Note: Rods must be retracted while adjusting bolt
projection. Use chassis (C) to retract top bolt & rod assy (A)
& bottom bolt & rod assy (D)
8) Slide rod silencer (G) over top bolt (F) onto rod, followed by top
chassis (E). Secure top chassis (E) to door with (2) screws (DD)
using holes (1A).
9A) For AD-8400 bottom bolt: Install bottom plate (N) over bottom bolt (M)
and secure with (2) screws (DD) using holes (6A).
9B) For MD-8400 & 12-MD-8400: Install bottom plate (O) over bottom bolt
(M) and secure with (2) screws (GG) using tapped holes (7A).
10) Install door into the frame using hinges
11) Slide rail assembly (H) onto chassis (C)
12) Align holes for screws (AA)
13) Level rail
14) Locate & mark holes for mounting plate (J) on hinge side.
Drill & tap (2) holes (4A).
15) Attach mounting plate (J) and secure rail assembly (H) to door
with (2) screws (CC).
16) Tighten screws (HH) & (FF) to secure chassis (C) to door
