Field Wiring
N OTE : Use conductors with a temperature rating of a minimum of 10k above the ambient temperature.
The Zone 2/22 ICS Page/Party
®
station provides terminal blocks for field wiring. Each connection for the
system cable has two terminals for daisy-chain wiring. Attach #6 spade lugs to the wires before
attachment to the terminal blocks for the most secure connection.
The terminal blocks on the Termination PCBA are labeled to coincide with the color code used on GAI-
Tronics 60029 Series multi-party cable or 60038 Series single party cable. Refer to Figure 4 for a sample
wiring diagram.

In certain circumstances where paging audio induces feedback, muting the speakers of two or more
stations during a page, referred to as mutual muting, can eliminate such feedback problems. This function
is enabled by connecting the spare orange wire between stations to terminal block TB4-2 or TB5-2.
