3.8.5 Local Playback Speaker Module (FC-LPS)
The Local Playback Speaker Module can be used to monitor the recorded digital message without transmitting the
message over the system speakers. The speaker module plugs into P2 of the main circuit board. This optional mod-
ule is necessary to take advantage of the Playback feature.
The Speaker Module is connected by simply plugging the module connector into P2 of the main circuit board. The
Speaker Module may be installed during the test period by using the supplied mounting hardware.
1.
Remove the main circuit board mounting screw located to the right of power terminal block TB3.
2.
Install the supplied metal standoff in the mounting hole just vacated in Step 1 and screw standoff into place.
3.
Position the FC-LPS mounting bracket hole over the standoff and secure with screw removed in Step 1.
4.
Plug the FC-LPS Local Playback Speaker Module's polarized connector into connector P2 on the main circuit
board. P2 is located on the bottom right of the main circuit board near the Control/Indicator panel.
5.
When testing is completed, remove the FC-LPS and standoff and reinstall the screw. The FC-LPS is not
approved for permanent connection.
