Abstract
A device to be connected to any standard alarm control panel for the verification of the actuated alarm includes one or two printed circuit board(s), preferably one, which is located within a house or integrated within the alarm control panel. On this board, which is referred to as an "Interface Module", are located an alarm panel interface for receiving the alarm signal from the alarm control panel, a specially programmed microcontroller, a non-volatile memory, an audio selecting matrix connected to at least one remote microphone unit, and a public switch telephone network (PSTN) interface, which is connected to a telephone line, through which the Interface Module communicates with the control station. The device may comprise many additional pieces of equipment, such as an audio storage unit; an integrated plug-in picture transmitter; a modem; a voltage free tamper output; an auxiliary voltage free nc/no relay(s) output; "power-on", "on-line", "failure" and "alarm" indicators; and an external unit enabling the testing and setting of the audio level of the inputs of the audio channel(s) and of any other parameters.
