Installation
Combination Manual Release/Abort
A combination Manual Release/Abort circuit allows an FACP to distinguish between a manual
release pull station and an abort switch installed on the same circuit. Any circuit can be pro-
grammed as a Combo Type zone. The following figure illustrates the wiring of Zone 2 as a Style B
(Class B) Manual Release/Abort circuit.

1.2 KΩ, ½ watt resistor P/N: 75579
Manual release
pullstation
Requirements for the Combination Manual Release/Abort circuit are as follows:
The manual release pull station must connect to the FACP Initiating Device Circuit before
the In-Line Resistor as shown in Figure 2.7.
The Abort Switch must connect to the FACP Initiating Device Circuit after the In-Line
Resistor as shown in Figure 2.7.
Program the FACP Initiating Device Circuit as a Manual Release/Abort combination circuit
as described in "Input Zones" on page 54.
