1. 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
signal processing means, responsive to said sensor means, said test means, and to control signals presented thereto, for presenting said actual value sensed signals at an output thereof in response to a first control signal presented thereto, and for presenting said test command signal to said test means and for presenting said test value sensed signals from said sensor means to said output in response to a second control signal presented thereto.

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.

8. A system for monitoring fire and security conditions in one or more spaces of a building, comprising:
-
sensor means, arranged in one or more groups, each group including one or more networks having one or more sensor means connected to a common sensor bus, each sensor means providing sensed signals indicative of the state of fire and security conditions in a space, and each sensor means presenting an alarm signal in the presence of sensed fire and security alarm condition in the space; master control means, responsive to said sensed signals from a group of said sensor means, and including a master control signal processor having master control memory means for storing signals, said master signal processor periodically sampling said sensed signals from each sensor means in each network of said group at a first frequency and sampling at a sensed frequency said sensed signals from each said sensor means providing an alarm signal, said master signal processor storing said sampled signals in said master control memory means, said master control providing, at reporting intervals, alarm report signals identifying each sensor means presenting an alarm signal and the sensed signals received therefrom, and normal report signals identifying sensed signals received from sensor means without an alarm signal; and central control means, including a central signal processor having central control memory means for storing signals, and including keyboard means responsive to operator control, said central control means being responsive to said alarm report signals and said normal report signals from said master control means, said central control means further including central display means for displaying each said alarm report signals to an operator. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
