Happy to assist!
If the system is not disarmed quickly enough, central station operators will respond based on how the account is setup. As this was a burglary alarm event a Chat notification was sent first, followed by a 2-Way call request shortly after.
When both the ARM Chat feature and 2-Way Voice are enabled , they will both be used but there will be a delay on the 2-Way call to allow time for the Chat session to be accessed.
The disarm command and code were given via text chat. However, the central station still contacted us via two way voice
To clarify, the ARM Chat feature through central station does not disarm the system. It does allow you to cancel/verify an alarm event in progress.
Based on history, the Chat session was accessed before the 2-Way call, but the alarm event was not disregarded via Chat until the 2-Way call was underway.
More information on the ARM Chat feature can be found here.
why didn’t they request the password if their protocol is to call despite the chat response?
They typically should require a password when verifying/cancelling an alarm event through 2-Way voice or via call to a listed Premise number outside of the ARM Chat. I have reached out to the monitoring station to figure out what happened here and I will follow up with more information.
About 1 second after disconnecting with the central station, the system alarmed again. We disarmed via the panel, with no further calls…Why wasn’t there another call from the central station after the second alarm event?
The system was not disarmed initially, as the Chat feature does not disarm the panel. After the 2-Way call ended, the panel siren resumed (the siren turns off for the duration of the 2-way call). As this is one alarm event, a new 2-way call or chat session would not have been generated.
