ABSTRACT:
An alarm for sensing different conditions of an ambient air presents a housing for an alarm circuit, the housing having lobes for first, second and third circuit sensors surrounding a single circuit alarm. The alarm circuit delivers the current to a logic chip which produces a current for sounding the alarm in different patterns according to the sensed air condition. The configuration of the housing depends the alarm below the housing proper so as not to interfere with the alarm sound. The housing allows the installation of three air condition sensors at one selected location.
