FIELD: signaling devices.
SUBSTANCE: invention relates to the field of burglar alarms and can be used in burglar alarm systems used on civil and navy vessels. Ship security alarm system includes a monitoring and control unit (MCU), containing a microcontroller, a keypad with buttons and a light indicator of the condition of the protected room, connected to the microcontroller, installed in the protected premises N expansion units (EU) and n security sensors, each of which is connected to the input of the corresponding N expansion unit (EU), the output of which is connected with the ability to transfer data to the input of the monitoring and control unit (MCU), sound and/or light emitters connected to the monitoring and control unit (MCU).
EFFECT: technical result – improving the accuracy of determining the place and time of unauthorized access and reducing the time of the alarm signal.
