• a plurality of handsets, and
• at least one base unit which was connected to the handsets by wireless communication,
• wherein the base unit is equipped with an emergency reporting priority table including priority information for determining a communication sequence of emergency information to the plurality of the handsets at the time of occurrence of an emergency, and
• in case that an abnormality was occurred and communication of the abnormality was carried out to a predetermined emergency center and the like, the base unit displays a message which informs the abnormality on a display part of itself, and
• in case that an alarm message, which shows a content of an alarm, is converted into a wireless signal and sent to the handsets, the base unit sends it to each handset in the order which followed the emergency reporting priority table.

A cordless phone apparatus which can be used in a security system, having

• a plurality of handsets, and
• at least one base unit which was connected to the handsets by wireless communication paths,
• wherein the base unit is equipped with an emergency reporting priority table including priority information for determining a communication sequence of emergency information to the plurality of the handsets at the time of occurrence of an emergency, and
• on the occasion of an abnormality, in case that an alarm message, which shows a content of an alarm, is converted into a wireless signal and sent to the handsets, the base unit sends it to each handset in the order which followed the emergency reporting priority table.

In a cordless phone apparatus which is equipped with a plurality of handsets, and at least one base unit which was connected to the handsets by wireless communication paths

• the handsets is equipped with
• means for obtaining, from a charging cradle which has particular charge number information, the charge number information, and
• means for transmitting the charge number information obtained, to the base unit, and
• the base unit is equipped with
• means for receiving the charge number information and storing it as position priority which shows more priority than a charging cradle position, into the emergency reporting priority table, and
• at the time of occurrence of an emergency, to the handset for which the priority information of the emergency reporting priority table is not set up, specified is such a position that the pertinent handset was placed, by time charging cradle to which charging was carried out in the last instance, and a priority sequence is determined in accordance with the position priority of the emergency reporting priority table.
