7.1.2 Indicating Circuit Wiring
The FA-300 Series Fire Alarm supports Class B or Style Y and Class A Style Z wiring for its
indicating circuits. Each circuit is supervised by a 3.9 k
Ω end-of-line resistor. Each indicating
circuit provides up to 1.7 A, 5 A maximum total if no auxiliaries are used.

Note: An active end-of-line resistor cannot be used with any indicating circuits. Always
use 3.9 k
Ω end-of-line resistors for indicating circuits.
