Abstract
A current detection circuit is connected in series with the TIP2 and RING2 lines of the alarm panel to detect when consumer provided equipment (CPE) is off-hook. When the alarm system goes off-hook, no current draw will be detected. The apparatus can thus distinguish the difference when a consumer device (phone, fax, modem) goes off-hook and when the alarm panel goes off-hook, and thus determine when the alarm panel is trying to dial out.
