Arm registration

Now that you’re monitoring my alarms I have to update the alarm system registration with the Montgomery County MD police Dept. The information they’re requesting is:

  1. The name of the monitoring company (SuretyDIY?)
  2. The monitoring company Montgomery County Alarm Business Lic number
  3. Contact phone number.

Where can I get this info.


For most business licensing information, to best assist, please submit a secure message to our customer service team.

However I have reached out to customer service and they have provided the following information:

The monitoring company would be AvantGuard Monitoring. If there is a Installed/Serviced by field, “Self” would be utilized.

AvantGuard Monitoring
P.O. Box 150224
Ogden, UT 84415

The requested Business License number would be 1278

Once you have received your local alarm permit number, please submit that number to us via the Secure Message tool so our team can associate that number with your account.

Again… many thanks! Great customer support
