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.
Apparatus adapted to be disposed in a building space for measuring the environmental conditions of the space, comprising: sensor means, for sensing the actual values of one or more parameters associated with the space environment, and for providing actual value sensed signals indicative thereof; test means, disposed to provide actuation of said sensor means in response to a test command signal presented to said test means, said actuation causing said sensor means to provide test value sensed signals indicative of the operability of said sensor means; and...
