The alarm is divided into unnecessary alarms, and switching between the alarm transmitting device and the telephone is performed as described below depending on the case where each alarm is involved.

When the telephone is used when the alarm is not transmitted, the telephone can be used.

When a telephone is used when an alarm transmission that needs to be prioritized is performed, a telephone cannot be used.

When the telephone is used when an alarm transmission that does not need to be prioritized is performed, the alarm transmission is stopped, and the telephone can be used.

[0007] In the case of transmitting an alarm which needs to be prioritized when the telephone is not used, the alarm can be transmitted.

[0008] When an alarm is not transmitted when the telephone is not in use, an alarm can be transmitted.

[0009] In the case of transmitting an alarm which needs to be prioritized when the telephone is being used, the telephone call is forcibly disconnected, and the alarm can be transmitted.

[0010] In the case where an alarm transmission that does not need to be prioritized is performed when the telephone is in use, the alarm transmission is not possible, and the telephone stands by until the telephone conversation ends.

When a telephone is not used, but an alarm is transmitted when there is an incoming call, an alarm cannot be transmitted and the apparatus stands by.

(2) Alarm transmission device described in Japanese Patent Application Laid-Open No. 64-13847 In this device, when an alarm is transmitted in a state where a telephone line to be used is used by a telephone call operation, There is provided a transmission priority circuit which forcibly disconnects a telephone line in which a call operation is being performed, draws the telephone line to the alarm transmission device side, and enables transmission of an alarm.
