Abstract
Alarm devices are provided with circuit means for permitting interconnection of the alarm devices into an alarm system in which each of the alarm devices continually senses for an adverse condition, such as smoke in a smoke detection alarm system, and in which all of the alarm devices signal an alarm in response to the sensing of an adverse condition. The interconnections for the alarm devices are such that the alarm devices not directly coupled to operative sources of electric power will, nevertheless, sense adverse conditions and signal alarms when any one of the alarm devices senses an adverse condition.
