Abstract

A security system adapted for monitoring fire, intrusion, and other alarm conditions employs solid state technology to appropriately identify the monitored alarm conditions and initiate appropriate responses. A 'one chip' integrated semiconductor circuit functions as the primary electronics of a master control console to accept both remotely initiated as well as locally initiated input signals and to process the signals and initiate appropriate control and alarm signals. Included on the integrated semiconductor circuit are a digital noise generator circuit, input comparator and latch circuits, system test and reset circuits, and logic circuits for developing digital output signals to both activate monitoring channels and identify the type of alarm condition present.
