A door locking popper is required when a fire door utilizes a top latching mechanism only (TRO). The popper is designed to
project a spring loaded bolt into the adjacent frame or door in the event of fire. Detex recommends
installing the popper in the edge of the door 12" above the threshold or finished floor. Holes for the popper
and plug must be aligned with each other.
NOTE: Door/Frame reinforcement is required where popper and cap plug are to be installed.
BOTTOM LATCH Testing and Adjustment
Testing
1. Close the door; bolt should drop into the strike as the door moves into the fully closed position.
2. Press the pushpad and open the door. The bottom latch bolt should retract out of the strike
and clear the strike by 1/16" to 1/8". Vertical travel of the bolt should be 3/4".
3. Release the pushpad; bolt should remain retracted until the door is closed.
Adjustment
1. If bottom bolt drags the floor or hits edge of strike:
Loosen bolt retainer in the carriage assembly and pull bolt from carriage. Screw bolt onto bottom rod one or
two turns and return it to the carriage. Test door to assure clearance and secure bolt in carriage by tightening bolt
retaining plate.
Adjust Bolt for approximately 1/16"
clearance between end of bolt and
surface of strike when retracted.
Open and close door to be sure bolt
does not hit high areas of floor.
Re-adjust if necessary. Confirm that
the bolt drops freely and does not
bind when latch is released
If additional length is required,
remove clip and link pin, move bolt
down and reinsert pin in
next lower hole. Insert clip on pin.
