3.8.5 Installing 4-Wire Smoke Detectors
Any compatible UL listed two-wire smoke detector can be used with the RPS-1000 panel. Refer to the Device Compatibility Document for a
list of compatible devices. Figure 3.16 and Figure 3.17 illustrate how to connect a UL listed four-wire detector to the RPS-1000 panel.
Installing Class B 4-Wire Smoke Detectors
Figure 3.16 illustrates how to install Class B 4-wire smoke detectors.
1.
Up to three Class B 4-wire smoke detector loops can be connected at once to the RPS-1000 panel.
2.
Each Class B loop input is paired with a unique power source as shown in Figure 3.16.
3.
Each loop gets smoke power from the even numbered I/O circuit and the contact input is connected to the odd numbered I/O circuit.

Note: I/O circuit 5 and 6 are
used as an example. Any I/O
point pairing can be used.
NOTE: In programming, any point that uses multiple I/O circuits are always referred to as the lowest I/O circuit number used. For example,
Figure 3.16 uses both I/O circuit 5 and 6, so in programming it would be referred to as point 5.
Installing Class A 4-Wire Smoke Detectors
Figure 3.17 illustrates how to install Class A 4-wire detectors.
1.
Up to two Class A 4-wire loops can be connected to the control panel at once.
2.
Smoke power is supplied to each Class A loop as shown in Figure 3.17.

NOTE: In programming, any point that uses multiple I/O circuits are always referred to as the lowest I/O circuit number used. For example,
since Figure 3.17 uses I/O circuits 1, 2, 3 together and 4, 5, 6 together they would be referred to as point 1 and point 4.

Note: The wiring class of the external power
source must match the wiring class of the
device being powered. Because the RPS-
1000 only has six Flexput circuits, a UL 864-
Listed Regulated Power Limited Power
supply must be used with Class A Aux Power
outputs to power the 4-wire detectors.
