The wiring between a Tracer MP581 and the FSCS is
•Tracer MP581 and FSCS must be in the same room.
•Wiring between the Tracer MP581 and FSCS must be in conduit.
•Wiring distance cannot exceed 20 ft.
•Wire must be #18 AWG.
The number of wires needed between the Tracer MP581(s) and the FSCS is determined by the total number of zones and manual override switches at the FSCS. Multiple Tracer MP581 panels may be required to monitor and control the FSCS. One Tracer MP581 controls the trouble LED and the Sonalert audible alarm of the FSCS, as well as supplying 24 Vac power to operate the lamp test relay(s).
Table 9 shows wires for a typical Tracer MP581 that controls the FSCS trouble LED and the Sonalert audible alarm.
Figure 14 on page 36 shows Tracer MP581 to FSCS wiring.
