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 4-48 uses both Flexput circuit 5 and 6, so in programming
it would be referred to as point 5.

Installing 4-Wire Smoke Detectors

Any compatible UL listed four-wire smoke detector can be used with the control panel (see Appendix A for list
of compatible smoke detectors). Figure 4-49 and Figure 4-50 illustrate how to connect a UL listed four-wire
detector to the control panel.

4.15.4.1 Installing 4-Wire Class B Smoke Detectors

Figure 4-49 illustrates how to install a 4-wire Class B smoke detector.
Conventions used for wiring 4-wire Class B loops:
1. One Class B 4-wire smoke detector loops can be connected to the control panel.
2. The Class B loop input is paired with a unique power source as shown in Figure 4-49.
3. The detector gets smoke power from Flexput 6 circuit and the contact input is connected to Flexput 5 circuit.

Conventions used for wiring 4-wire Class A loop:
1. One Class A 4-wire loop can be connected to the control panel.
