Tracer MP581 to FACP wiring
The wiring between the Tracer MP581 and the FACP is non-supervised
and power limited. In addition:
• Tracer MP581 and FACP must be in the same room.
• Wiring between the Tracer MP581 and FACP 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 FACP
is determined by the total number of zones in the fire alarm system.
Multiple Tracer MP581 panels may be required to monitor and control
the FACP.
Table 10 gives wiring information for a typical Tracer MP581 that
communicates to an FACP.
Figure 15 on page 38 shows the details for wiring a Tracer MP581 to an
FACP.
