INTRUDER ALARM DEVICE FOR ELECTRIC COMMUNICATION OBJECTS Russian patent published in 2008 - IPC G08B25/08 G08B26/00 

FIELD: engineering of devices for controlling schedule of operation of objects, including electric communication objects, and which also realize protective functions in emergency situations, which happen in case of breaking and entering, fire, flooding, etc on these objects.

SUBSTANCE: intruder alarm device for electric communication objects contains a microprocessor block with power supply, which is made in form of microprocessor controller, to inputs of which voltage control blocks are connected, made in form of blocks for controlling power supplying input, which ensure single-period rectification, moisture control sensitive elements, semiconductor temperature sensors, block for reading condition of a group of discrete sensors and block for reading from individual chip-keys, and outputs of microprocessor controller are connected to issued siren and the block for engagement with sound annunciator, where the power supply unit is connected to electric supply net of electric communication object.

EFFECT: expanded functional capabilities, ensured adaptation to objects of electric communication independently on their position due to realization of device according to modular principle.
