4.15.2.2 Class A Inputs
You can connect conventional Class A switches, such as waterflow switches and pull stations, directly to the
Flexput circuits of the control panel.
To install a Class A switch:
1. Wire the Class A switch as shown in Figure 4-50.
2. Configure the circuit through programming (see Section 9.5).

Note: In programming any point that uses multiple Flexput circuits, the lowest Flexput circuit number is used to
refer to the circuit pair. For example, Figure 4-50 uses both Flexput circuit 1 and 2, so in programming it
would be referred to as point 1.
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 4-51 and Figure 4-52 illustrate how to connect a UL listed 2-wire
detector to the control panel.
