I spoke to a representative on the phone who indicated that the alarm.com system has the capability to set a schedule as to when the system will self-arm and self-disarm. However, I have been unable to find any documentation online that indicates how this can be done.
I have had a Lowes Iris home security system which has the capability to do this. Simply, every night at 11pm my system auto-armed. Every morning my system auto-disarmed at 6am.
Can this be done with the Brinks system?
