2.8.5 CAC-5F Class A Converter Module
The CAC-5F module converts the Style B (Class B) Initiating Device Circuits to Style D (Class A). The CAC-5F
mounts to terminal block TB2 located in the upper center of the main circuit board. Refer to Figure 2-17, “CAC-5F
Style D Converter,” on page 32. The removable terminal block on the CAC-5F module provides for ease of wiring.
Notes:
1.
Circuits 1 through 5 can accommodate 2-wire smoke detectors, plus any normally open contact device such as
heat detectors or manual pull stations.
2.
Only circuit 3 accommodates the nonsilenceable waterflow function.
