inactive current load. A finite amount of additional current must be provided by the
power supply during an activated condition. Use Table 6 to determine the activated
load. The requirements for inactive and active current loads cannot exceed the
capabilities of the power supply in either case.
A total of 3.0 amps (internal) @ 24 VDC is available from the MPS-24A/MPS-24AE
Main Power Supply during inactive conditions. No more than 6 amps @ 24 VDC can
be drawn from the MPS-24A/MPS-24AE during active conditions (only if the XP
Transponder is in local mode). If the XP Transponder is not in local mode only, 3.0
amps may be drawn in an activated state. The MPS-24B/MPS-24BE provides 750 mA
of filtered power for system modules and 2.0 amps for notification appliances.

Table 5 Filtered Power Requirements (Not Activated) @ 24 VDC
Table 6 allows the system designer to determine the percentage of the system that
should be supported by the Main Power Supply during an activated condition. Enter the
number of circuits, by device type, that the Main Power Supply should power
simultaneously in an activated state.
