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
for list of compatible smoke detectors). Figure 4-38 and Figure 4-39 illustrate 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 4-38 illustrates how to install a 4-wire Class B smoke detector.
Conventions used for wiring 4-wire Class B loops:
1. Up to four 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 4-38.
3. Each loop gets smoke power from the even numbered Flexput circuit and the contact input
is connected to the odd numbered Flexput circuit.
Maximum
Impedance per
Circuit is 50Ω
Note:
Flexput circuit 5 and 6
used as an example.
Any Flexput point pairing
could be used.
Figure 4-38 Class B 4-Wire 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 4-38 uses both Flexput circuit 5 and 6, so in programming it
would be referred to as point 5.
