Providing Power to Annunciators
Sensiscan 2000 panels use the MPS-24AF or the MPS-24BF Main Power
Supply. This 24 VDC output is filtered, regulated, power-limited, and non-
resettable.
MPS-24AF - 3 A maximum current draw
MPS-24BF - 200 mA maximum current draw
The power run to the annunciator does not require a Power Supervision Relay
because loss of power is inherently supervised through a communications
loss.
Note: When not using the trouble input on annunciator or expander, jumper Trouble
Input terminals of TB1 on annunciator together.
MPS-24AF Main Power Supply - Connect the power run for the
annunciator module to the MPS-24AF TB3 Terminals 3(+) & 4(–), as shown
below.

MPS-24BF Main Power Supply - Connect the power run for the
annunciator module to the MPS-24BF TB2 Terminals 3(+) & 4(–)as shown
below.
