Figure 8: Main Power Supply Connections
The annunciator can be powered by an MPS-24AF or an MPS-24BF. The power run to
the annunciator need not contain a Power Supervision Relay since loss of power is
inherently supervised through communication loss.
MPS-24AF Main Power Supply
Connect the power run for the AFM to MPS-24AF TB3 Terminals 1 (+) and 2 (-) (1 amp
max). The total amount of current drawn from these terminals cannot exceed that rating
in standby or in alarm.
MPS-24AF
MPS-24BF Main Power Supply
Connect the power run to MPS-24BF TB2 Terminals 1 (+) and 2 (-). No more than 200
mA current can be drawn from these terminals in standby or alarm.
