25. AC Fuse – T8A L250
26. Main Power Switch – Turns AC power to the C-6 Controller ON/OFF.
27. Zone Keypad/Speaker Terminal – Six plug-in four terminal screw connector terminals for
connecting K-8, K-22 Keypads and speakers in remote zones.
WARNING: THESE ARE NOT TYPICAL SPEAKER TERMINALS. IMPROPER
CONNECTION OF SPEAKERS OR KEYPADS CAN CAUSE DAMAGE TO THE
CONTROLLER, THE KEYPADS AND SPEAKERS. SEE SECTIONS: ‘CONNECTING THE
CONTROLLER - ZONE CONNECTIONS’ AND ‘ZONE CONNECTIONS AND SETUP -
KEYPADS/SPEAKERS’ BEFORE MAKING ANY CONNECTIONS OR TURNING ON THE
MAIN POWER. NEXUS WARRANTY DOES NOT COVER DAMAGE CAUSED BY
IMPROPER CONNECTIONS.
