Abstract
A dialer intercept module is provided in an event detection system for automatically selecting between alternative communication channels and formats based on detected characteristics of control panel signals. More specific features detect predetermined signals, such as the telephone number dialed by the panel, or the type of alarm, and determine from the predetermined signals whether to: a) send the signal as is, over a publicly switched telephone network (PSTN); or, b) translate the signal into a different format suitable for an alternative channel, such as a wide area computer network.
