The MPS-24A/MPS-24AE automatically employs Ground Fault Detection (required in
Canada) unless resistor R27 is removed. The detector circuit does not make a distinction
between positive and negative faults. It is normal for the MPS-24A/MPS-24AE to
indicate Ground Fault Trouble during power-up. This feature must be disabled on all but
one power supply if multiple power supplies are present and share a common signal
reference.

Up to one amp of current for four-wire smoke detectors can be drawn from TB3
terminals 1 (+) and 2(-) on the MPS-24A/MPS-24AE. Power is removed from these
terminals during system reset. This 24 VDC filtered four-wire smoke detector source is
power limited, but must be supervised via an end-of-line power supervision relay. This
power supervision relay is energized by the four-wire power circuit and its contact must
be connected in series with an XPM-8 or XPM-8L Initiating Device Circuit (IDC).

Up to 3 amps of filtered current for powering notification appliances can be drawn from
TB3 terminals 3 (+) and 4(-) on the MPS-24A/MPS-24AE. The actual amount of
power that may be drawn is determined by the calculations in Appendix B. If the MPS-
24A/MPS-24AE power supply is powering more than one XPP-1, all these current
draws must be added together. Power is not removed from these terminals during a
system reset. If a resettable power circuit is desired (2 amps maximum), cut JP5 on the
MPS-24A/MPS-24AE.

Internal power for the XP Transponder is provided via the Power Harness, 75100 (42
inches, or 1.067 meters) or 75099 (16 inches, or 406.4 millimeters). Connect this
harness from P2 or P4 on the MPS-24A/MPS-24AE to plug P9 on the XP Transponder.
Connect the supervisory cable (71031) from MPS-24A/MPS-24AE plug P3 to XPP-1
plug P7. Refer to Figure 10 for MPS-24A/MPS-24AE connections.
