Measuring panel voltage is a common troubleshooting step when experiencing odd behavior on a panel. Most often, this step is required when there is a Modem-Panel Comm message, or the panel is not communicating properly with Alarm.com. For more information about measuring the voltage, see Measure panel and module voltage.

Power requirements

The Neo panel has a 16.5V power supply. Voltage outside of 16-18V range could cause modem-panel communication trouble.

The following table displays where to test voltage and what the recommended voltage is for the DSC PowerSeries Neo:

Panel power requirements	16-18 VAC
Battery power requirements	11.5-12.5 VDC
Where to measure panel voltage	The two AC terminals on the main panel board.
Alarm.com module power requirements	11.3-13.5 VDC
Where to measure module voltage	The 12V and Ground (GND) terminals on the module gateway board.

For more information about power budget for specific devices, see DSC PowerSeries Neo - Power Budget Calculator.

Wire size and maximum length

The following table displays the typical maximum wire length by gauge size that can be used to connect Alarm.com cellular modules to modular panels (i.e., DSC PowerSeries Neo/Pro, Interlogix Concord, NX, System Enhancement Modules, etc.).

Gauge	Length
22 gauge	40 feet (12.2 meters)
18 gauge	90 feet (27.4 meters)

Note: Doubling wires and Cat5e cables (and its variants) are not supported. For more information about using Cat5e cables, see Can Cat5e cables be used to connect Alarm.com cellular modules to panels?.
