Adjust Cable Length - Kaba Mas High Security Pedestrian Exit Device with Electric Locking Trim Installation Manual

Adjust Cable Length

The effective cable length may be changed by turning the brass threaded plug into and out of the turnbuckle.
The cable length must be adjusted so that as the push bar of the Rim Exit Device is depressed, the CDX-09
bolt is fully retracted and latched back just before the Rim Exit Device latchbolt clears its strike. Refer to
Figure 24 and Figure 25 in preparation for adjusting the cable length. The proper sequence of adjustment is:
1. With the door open, slowly depress the push bar and determine if the CDX-09 bolt retracts and latches back
prior to maximum depression of the push bar. If the CDX-09 bolt does not retract and latch back, slightly
shorten cable and recheck.
2. Close the door and slowly depress the push bar until the Rim Exit Device latchbolt just clears its strike.
Check to see if the CDX-09 bolt is fully retracted and latched back at this point.
If not fully retracted and latched back: Shorten the cable length until the CDX-09 bolt retracts and latches
back just before the Rim Exit Device latchbolt clears its strike.
If fully retracted and latched back: With the door open, depress the push bar until the CDX-09 bolt retracts
and latches back. Depress the CDX-09 bolt reset latch to allow the CDX-09 bolt to extend. Check to see if the
pulley restores clockwise sufficiently to prevent the CDX-09 bolt from being pushed back. (A thin-blade
screwdriver may be inserted between the end of the bolt and the bolt guard for the purpose of pushing back
on the bolt.) If the CDX-09 bolt can be pushed back, slightly increase the cable length and recheck the CDX-
09 bolt latching status by following the directions in Step 2 above. If necessary, needle nose pliers may be
used to preset the "curl" to the pulley end of the cable.
3. Tighten the brass nut on the threaded plug against the turnbuckle.

4. Adjust the CDX-09 strike such that the throat of the strike has minimum clearance of the bolt guard when
the door is contacting the jamb.
5. Mark or transfer punch the locations of the remaining three (3) flat head screw locations for the CDX-09 strike.
