2.13 Installation of Option Modules
BEFORE INSTALLING ANY MODULES OR CABLES, MAKE CERTAIN ALL POWER (AC AND DC)
HAS BEEN REMOVED AND BE SURE TO OBSERVE PROPER GROUNDING AND HANDLING
2.13.1 ECC-CE6 Circuit Expander Module
The ECC-CE6 Circuit Expander Module provides connections for up to six Style Z (Class A) or
Style Y (Class B) speaker circuits. Circuits are configured through the web-based programming
utility. Refer to Section 3.2.2 on page 61.
ELR required for Style Y -
Class B only
15K, 1 watt, P/N:ELR-15K
2.13.2 Audio Amplifier Module (ECC-50W-25/70V)
The optional audio amplifier module can be used to provide a second 50 watt speaker circuit,
increasing the total ECC-50/100 power to 100 watts, or it can be used as a backup amplifier. Refer
to Section 3.2.2 on page 61 for programming the amplifier's operation. Connectors J1 & J2 of the
audio amplifier module plug into connectors J10 & J11, respectively, located at the upper right of
the main control board.
Figure 2.33 shows the installation of a ECC-50W-25/70V onto an ECC-50/100 panel. The optional
amplifier may be programmed and wired for backup or for providing a second audio channel.
NOTE: Both the primary and secondary amplifiers must be same voltage output (25V or 70V).
Remove mounting screws shown, from the main control board, and save (refer to Figure 2.33).
Install four supplied metal standoffs in locations from which mounting screws were removed
in Step 1.
Secure the Audio Amplifier Module with the screws removed in Step 1. It is important to
secure the module with the metal screws in order to help protect against electrical transients.
