The CPU 7 is provided with a two-step time period having a different time width, for example, a counting operation in which one minute is divided into 50 seconds and 10 seconds. A timer circuit 8 for outputting a signal and an alarm sound generator 9 for emitting alarms of different timbres from the alarm speaker 3 are connected.

This alarm is based on a two-step count signal from the timer circuit 8 and outputs a continuous sound with a slow tempo "ping-pong, ping-pong", followed by a continuous sound with a fast tempo such as "pip-pong". 3 and telephone 12
The sound is emitted from the doorphone slave device 13 via the.
The alarm unit 1 is connected to a voice synthesis analysis circuit, which is not shown in the figure, and is set to the alert state. When the entrance door is opened and closed, when the door opening and closing switch 11 is opened and closed, Based on the operation signal, "The security alert has been activated. Is generated, and sound is emitted from the audio speaker 4.

Thus, the security crime prevention system can be set to a security state by operating the security switch 2 when a resident goes out.
That is, when the security switch 2 of the alarm unit 1 is operated, the CPU 7 receives the warning setting signal and shifts to the warning state, and sends an ON signal to the timer circuit 8 to operate as shown in FIG. .

Then, the count output of the first stage is supplied from the timer circuit 8 to the alarm sound notice generating section 9 to be activated, whereby the alarm set notice sound signal is transmitted via the alarm speaker 3 and the telephone 12 to the door phone handset. 13 and FIG.
Sound is emitted from the time t1 to t2 shown in FIG.
Therefore, the operator can hear the alarm set notice sound P1 of “ping-pong, ping-pong” for 50 seconds set in advance, and then when the count time t2 of the second stage has been reached, the sound of the tone is different from the warning notice sound generation unit 9. An alarm set notice sound signal is output. For this reason, the operator hears the alarm set warning sound P2 of "beep" at the time t2 after 50 seconds have passed, and opens and closes the entrance door 10 while predicting that the time t3 has elapsed and the user will be alert. Then, they can go out and lock.
