672 Series TouchBar
INSTALLATION AND WIRING MANUAL
GENERAL DESCRIPTION: The 672 Series Request to Exit TouchBar is a non-latching releasing device. It is most
often used as a switch to release a magnetic lock. A double pole output is standard, and allows for use when
integrating with a monitoring system which requires a signal for legal egress. The device can be ordered to fit 3
standard door openings or can be cut to size in the field. A 24-inch (minimum) pre-connected cable comes standard
to make installation easier.
These devices are to be installed in accordance with the applicable codes and the local authorities having jurisdiction.
It is up to local authority having jurisdiction whether this is to be installed in lieu of panic hardware.

STEP 1
Place the TouchBar on the door and measure the distance
between each end and the stop (or frame on a blade stop
door). It should be at least 3/8” of an inch. If so, proceed
to step 2. If not, the TouchBar will need to be cut to size.
1. REMOVE END CAPS AND BRACKETS.
2. REMOVE PIVOT HINGE COMPONENTS AND
SWITCH COMPONENTS. KEEP THE PIVOT
HINGE AND SWITCH ASSEMBLIES TOGETHER
WHEN DISASSEMBLING DEVICE.
3. SLIDE OUT PUSH PAD AND EXIT SIGN
(IF FURNISHED) AS SHOWN. SLIDE OUT
COVER PLATE.

CUTTING TOUCHBAR TO SIZE:
A. Measure the DOOR WIDTH, hereafter referred
to as dimension “X”
HOLLOW METAL OR WOOD DOOR:
DIMENSION “X”
B. Disassemble the TouchBar as shown below: CHANGING HAND:
1. REMOVE SWITCH SIDE

C. Calculate the correct length to cut the housing extrusion and pushbar extrusion using the door
width as determined in step 1 (dimension “X”).
D. Calculate the correct length to cut the cover plate extrusion using the door width determined in
step 1.
E. Cut metal parts to length determined above (using a metal miter saw is recommended to
ensure a good clean cut and a right angle). Do not cut the plastic push pad.
F. Reassemble the TouchBar (without installing the end caps). Note that the screws which connect
parts to the aluminum extrusions are self tapping (thread forming) screws. It is recommended that
a power tool be used to drive them in. This will make assembly easier.
NOTE: AT THIS TIME THE TOUCHBAR CAN BE HANDED BY ASSEMBLING THE
“PUSH TO EXIT” SIGN (IF FURNISHED) IN THE CORRECT ORIENTATION.
EXTRUSION LENGTH = “X” - 4 13/16”
COVER PLATE LENGTH = “X” - 20 7/8”

b. Place a channel end cap bracket over the centerline.
c. Center wire hole in the adaper plate with the centerline that was marked on door. (See below)
d. Mark center of wire hole and center of one mounting hole.
d. Drill a 5/8” wire access hole at wire hole mark. DO NOT DRILL WIRE HOLE THRU DOOR.

STEP 3: WIRING
Provision must be made for conductors to get to the
device on the door. Common methods are an electric
hinge, door cord, or power transfer device. Purchase
with AR option to receive a model 798-18 armored
door cord to facilitate power transfer. Make wiring
connections as required by the system wiring dia-
gram. Contact colors are shown below:
DPDT(STANDARD)
4 AMPS @30VDC
SWITCH ADJUSTMENT:
The switch sensitivity is set at the factory. If the switch is
determined to be too sensitive or not sensitive enough it
can be adjusted by loosening the screw which secures
the switch assembly and sliding the switch to the left or
right. BE SURE TO TIGHTEN THE SCREW AFTER
ADJUSTMENT.

BLIND NUT INSTALLATION:
a. Drill four 9/32” holes on device side only of door in positions marked in step 3.
b. Install blind nuts as shown to right.
c. Secure device using # socket cap screws.
I. Assemble tool to install blind
nut as shown using the parts
supplied.
II. Install blind nut assembly
