Battery Supply Off Command

When the battery voltage decreases to less than “Vmin Batt” (Figure 1) the

battery supply to the M-7679 R-PAC will be turned off to protect the battery.

The M-2035 remains connected to the battery. Discharging batteries below

certain levels will shorten the life of or damage the battery.

Threshold voltages can be edited in IPScom/Common Setpoints/IED Power

Supply/Battery Charger Monitor screen.

Wakeup System Command

The Wakeup system command is initiated with local panel pushbutton, allowing

the user to wake module from the Sleep Mode that was initiated by the Battery

Supply Off command. The wakeup system command restores power to the unit

for a user defined time period. If the main source power has not been restored,

the Battery Supply Off command will be repeated. The loss of main power is

determined by monitoring the battery current throughput polarity.
