Abstract
The security system uses two-way audible type communication signals between a detector and a control panel. Each of these devices include microphones and processing arrangements for filtering the signals to recognize and evaluate the communication signals. The microphone of the control panel can preferably be part of an alarm detection and also part of a two-way voice communication with a monitoring station. This arrangement is convenient to install, reliable and cost effective.
