Control Panel Installation

4.13.4 Installing 4-Wire Smoke Detectors

Any compatible U.L. listed four-wire smoke detector can be used with the control panel (see Appendix A for list of compatible smoke detectors). Figure 4-34and Figure 4-35illustrate how to connect a UL listed four-wire detector to the control panel.

4.13.4.1 Installing a Class B 4-Wire Smoke Detector

Figure 4-36illustrates 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.

3.Each loop gets smoke power from the even numbered Flexput circuit and the contact input is connected to the odd numbered Flexput circuit.

Note:

Flexput circuit 5 and 6 used as an example. Any Flexput point pairing could be used.

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 4-36uses both Flexput circuit 5 and 6, so in programming it would be referred to as point 5.
