Option Module
The Option Module provides advanced call processing features like External Call Forward,
Automatic Busy Redial, etc. (Generally, features that require enhanced call monitoring via
Tone Detectors and DTMF receivers). The Option Module is equipped with two DTMF
receivers and two Tone Detectors. In addition, the Option Module provides two music
source inputs (one that replaces the Standard MOH/BGM Module), one External Page
Zone port and one Loud Bell Control contact.
Follow these steps when installing the Option Module:
1. Be sure that KSU power is turned OFF, and cover is removed.
2. Connect grounded wrist strap to a suitable earth ground.
3. Locate the Standard MOH/BGM Module already in place. Notice that there is one
screw that secures the Standard MOH/BGM Module to the CPU Module.
4. Remove the MOH/BGM Module screw and MOH/BGM Module. Then remove the
short stand-off post used to mount the Standard MOH/BGM Module. Retain these
pieces in the event that the Option Module is to be eliminated and standard MOH/
BGM operation is again desired.
5. Install one of the stand-off posts supplied with the Option Module into the position
previously occupied by the short stand-off post. Use Step 8 as a guide for tightening
the stand-off post. Locate the remaining three screws used to secure the CPU
Module.
6. Remove one of the module securing screws at a time, so that the CPU Module stays in
place, and retain the removed screw.
7. Insert one of the Option Module stand-off posts into the screw position where the
screw from Step 6 was removed.
8. Tighten securely by hand, then snug tight using a small hand tool. It is very important
not to over-tighten any screw or stand-off post as damage to the module may occur.
9. Repeat Steps 6 through 8 until all module screws are replaced with stand-off posts.
10. Position the Option Module over the stand-off posts installed such that the ribbon
cable and connector are oriented at the top right of the module (Assuming correct
KSU installation).
11. Locate the Option Module connector located on the CPU Module labeled “JP1” and
carefully attach the Option Module ribbon cable to JP1 assuring that all connector
pins are properly aligned.
12. Use the screws retained in Step 6 to secure the Option Module to the stand-off posts
installed.
13. Replace KSU cover and secure with cover screws.
14. Restore KSU power when all wiring is complete, or continue with the
installationprocess.
It is very important that all pins make contact to the connector and that no pins become
bent in this process
