With Surety’s default procedures, only 2 way voice and the premises number are called prior to dispatch on fire alarms. If there is no premises phone or 2 way voice enabled, then they will dispatch immediately. AvantGuard did follow the normal protocol.
If you do not have a location phone, I’d recommend sending a private message to Surety support to have special instructions placed on the account for fire alarms. Doing so will allow you to just have the cell contacts, but still have them call to verify for fire alarms.
I also recommend checking out Surety’s default procedures for more information on how alarm signals are handled.
Sometimes the fire department will cancel their response if requested, but most of the ones I’ve heard of will not.
