LC-S SYSTEM WITH TALKBACK PAGING HORN
Your LC-S system can not be connected to a standard paging system. In adition your LC-S system was not
designed to incorporate talkback paging horn substations. However, a talkback paging horn may be added to your system
as shown below. You must keep in mind that the LC—3S has an output of 220 mw, and the LC—5S and LC—lOS has an
output of 400 mw.
LT-1 matching transformer is designed for using a standard 8 ohm horn in place of a substation.
15 MFD non-polarized capacitor must be installed between number terminal on master and a red lead of LT-1.
