4.12.3.2 Installing 2-Wire Class A Smoke Detectors
To install a Class A two-wire smoke detector, wire as shown in Figure 4-35.
Figure 4-35 Two-Wire Class A Smoke Detector Connections
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 4-35 uses both Flexput circuit 5 and 6, so in programming it
would be referred to as point 5.
4.12.4
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 4-34 and Figure 4-35 illustrate how to connect a UL listed four-wire
detector to the control panel.
4.12.4.1 Installing 4-Wire Class B Smoke Detectors
Figure 4-36 illustrates how to install a 4-wire Class B smoke detector.
Conventions used for wiring 4-wire Class B loops:
1.
Up to three Class B 4-wire smoke detector loops can be connected to the control panel at once.
2.
Each Class B loop input is paired with a unique power source as shown in Figure 4-36.
Note:
Flexput circuit 5 and 6
used as an example.
Any Flexput point pairing
could be used.
