3.9 Zone Installation
The HCA series panel has either 2, 4 or 8 class B (style B or C) conventional input zones depending on the
HCA model chosen. The mode programming option determines if the zone logic interprets short circuits as
an alarm (style B) or a trouble condition (style C). Wire the smoke detector positive terminals to the HCA
terminal labeled
“+” and the negative smoke detector terminals to the HCA terminal labeled “-“ as shown in
figure 3.8 which shows the HCA-8 panel. Each active zone requires a 4.7k
end of line (EOL) resistor at
the very end of the zone as shown in figure 3.8.
