Testing and Adjusting Exit Device Operation
1. PERFORM a visual inspection to make certain exit device will be level and secure.
2. TEST the operation of the Active Push Bar and the top and bottom bolts and ADJUST as necessary.
3. VERIFY that the top bolt retracts and latches, as appropriate.
4. VERIFY that the top and bottom bolts are flush with the door edges when retracted.
5. PUSH top jam sensor and VERIFY the top and bottom bolts project to 5/8” from the door edge.
6. IF bolts do not move,
THEN CHECK rods for binding.
NOTE: The following is not applicable to fire-rated exit devices. Dogging the Active Push Bar disables
the latching function, making the door a simple push/pull operation.
7. DEPRESS and HOLD active push bar in unlocked position.
8. INSERT and ROTATE hex key one-quarter turn clockwise to lock device (dog) into position.
9. ROTATE hex key one-quarter turn counterclockwise to unlock device and release device into
motion.
10. ENSURE exit device is operational and ADJUST as required.
NOTE: Over-rotation of the key past the prescribed one-quarter turn may cause damage to the exit
device.

Preparing the Header and Threshold
NOTE: Misalignment of mounting holes will prevent bolts from traveling into the deadlocked position.
1. POSITION door inside opening such that it is plumb and square, and door freely swings open.
INSTALL door according to manufacturer’s instructions.
2. MARK locations for bolt holes very carefully, allowing for weather stripping, if applicable.
3. MARK and DRILL 9/16” diameter center hole in threshold to receive bottom bolt.
To accommodate maximum bolt engagement, depth of hole in must be 3/4” deep, measured from top of threshold and header.
4. MARK, CENTER PUNCH, DRILL 1” dia center hole in header to receive top bolt.
5. MARK, CENTER PUNCH, DRILL two (2) 1/8” dia holes in header to attach header strike.
6. The center point of the two (2) 1/8” dia holes must be symmetrical with the 1” dia hole centerline.
7. INSTALL header strike plate using included #6 x 1/2” self-tapping Phillips flat head screws and shim
plates, as required.
Two (2) 1/32” and two (2) 1/16” shim plates are included to mount between header strike plate and frame, as required, in order to maintain no more than 1/8” gap between top of door and header strike plate.
ENSURE gap between top of door and header strike plate is no more than 1/8”.
8. INSTALL header strike plate using included #6 x 1/2” self-tapping Phillips flat head screws and shim
plates, as required.
9. CLOSE door. VERIFY proper operation of door and exit device. ADJUST as required.

Adjusting the Bolts
The following steps address how to adjust bolts for proper engagement with the header and threshold for varying installed door gaps.
Top Bolt
1. MEASURE the door gap at the header. ADD 1/2” to this measurement to a maximum allowable
adjustment of 5/8”.
2. PUSH in active push bar to retract top bolt. OPEN door.
3. ADJUST top bolt by pushing it inwards and rotating clockwise or counterclockwise until the released
projection equals the measurement calculated in Step 1. The bolt projection will change 1/8” for every 3 full rotations of the bolt.
4. ALIGN hex shape of top bolt with hex shape of bolt guide.
CLOSE door. VERIFY proper operation of door and exit device. ADJUST as required.
Page | 12 P 800.872.3267 F 800.232.7329 E techsupport.adamsrite@assaabloy.com www.adamsrite.com
Bottom Bolt
1. MEASURE the door gap at the threshold. ADD 1/2” to this measurement to a maximum allowable
adjustment of 3/4”.
2. PUSH in active push bar to retract bottom bolt.
3. LOOSEN top mounting screw of bottom bolt guide. OPEN door.
4. ADJUST bottom bolt by rotating it clockwise or counterclockwise until the released projection equals
the measurement calculated in Step 1.
The bolt projection will change 1/8” for every 3 full rotations of the bolt.
5. ENSURE the flat side of hex bolt and bolt guide are parallel to the inner stile face.
6. TIGHTEN top mounting screw of bottom bolt guide.
7. CLOSE door. VERIFY proper operation of door and exit device. ADJUST as required.

Installing the Mounting End Caps
1. INSTALL hinge side mounting End Cap on hinge
side of door using two (2) #8-32 x 3/8” tri lobe pan head screws.
2. INSTALL latch side mounting End Cap on
latch side of door using two (2) #8-32 x 3/8” tri lobe pan head screws.
Maintenance
1. CHECK mounting fasteners periodically and TIGHTEN if loose.
2. APPLY screw locking compound or CHANGE part fasteners if screws continue to back out.
3. PERFORM periodic and required checks and adjustments of strikes to compensate for wear and tear
such as door sagging.
