Abstract
An alarm system at a premises reduces the overall delay in signalling an alarm condition in the presence of an entry delay timer. The alarm system establishes, or commences the establishment of, a network connection prior to the expiry of the entry delay. This allows an alarm message to be quickly dispatched upon expiry of the entry delay timer, or if a tamper condition is sensed.
