Rauchmeldevorrichtung

摘要

A smoke alarm modular base (10) contains an interconnect interface (30) for wireless communication with other devices in a group. An alarm device (1-7) is completed by push-fitting an alarm unit to the base (10). An antenna (15) is curved within a housing, or may be extended out through an aperture (16). The interconnect interface is activated when the alarm unit is pushed into place, by a protruding switch (25). Pressing of a house coding switch (28) of a number of devices in quick succession causes them to communicate a unique device identifier to each other so that a network group is automatically learned.
