Abstract
A fire and security system includes a hierarchical architecture with a central control processor monitoring each of a plurality of multi detector-occupancy-temperature-smoke (MDOTS) sensors mounted in each of the monitored spaces of the building, the MDOTS sensors connected in multi drop fashion in sensor loop networks which are connected to one of a plurality of master controls, each master control monitoring the sensor outputs from one or more sensor loops and reporting the alarm status of any one sensor to the central.
