PROBLEM TO BE SOLVED: To perform a normal notification when security abnormality is detected in sensors of a plurality of slave unit terminals, while a master unit terminal is provided with a program rewrite function compatible with a communication protocol of at least one slave unit terminal. SOLUTION: In a wireless security notification apparatus, a CPU 204 of a master unit terminal 2 for performing radio communication with at least one slave unit terminal 1a, 1b rewrites a program for controlling a digital-controlled radio transmission/reception circuit 200 receiving radio data with information on security abnormality detected by a sensor 100 of a slave unit terminal, based on a program read from a memory card 3 detachably connected to a card slot 202 or a program transmitted from an external network 4 via a LAN connection control circuit 203 into a program compatible with a communication protocol for each slave unit terminal. The CPU sets a reception time for receiving radio data transmitted from the plurality of slave unit terminals shorter in comparison with a transmission time of radio data that can be transmitted from the plurality of slave unit terminals to the master unit terminal.
