4.15.2 Class A Inputs
You can connect conventional Class A switches, such as waterflow switches and pull stations, directly to the Flexput circuits of the con-
trol panel.
To install a Class A switch:
1. Wire the Class A switch as shown in Figure 4.46.
2. Configure the circuit through programming (see Section 9.5).

4.15.3 Installing 2-Wire Smoke Detectors
Any compatible UL listed two-wire smoke detector can be used with the control panel (see Appendix A for list of compatible smoke
detectors). Figure 4.47 and Figure 4.48 illustrate how to connect a UL listed 2-wire detector to the control panel.

NOTE: In programming any point that uses multiple Flexput circuits, the lowest Flexput circuit number is used to refer to the circuit pair. In this
example, Figure 4.46 uses both Flexput circuit 5 and 6, so in programming it would be referred to as point 5.
