2.2.1 Power
If the D8125INV is powered down and then back up, it may take up to a maximum of 5 minutes (up to 15
minutes for 5 minute Transmitter Check-In Time) for all the transmitters to report back to the D8125INV
with their current status. On systems employing fewer transmitters, this time is reduced proportionately.
In addition, when the D8125INV is powered up, all programmed RF points will report Normal until their
state is updated.
The D8125INV power should be connected to the control panel using the Aux Power terminals. If the D8125INV were to
lose power, the following conditions may result:
• All RF points will report to the control panel as missing (trouble/alarm)
