Abstract
In a polling type surveillance control apparatus for a security system, inherent addresses are assigned to respective terminal devices such as smoke detectors, temperature sensors, gas leakage detectors, fire partitions and smoke dampers. When a self address detector in the terminal device detects a coincidence between the address signal from a central station and a preset self address, the terminal device indicates it has been accessed or energized and power control thereof may also be performed.
