1. An alarm for sensing a plurality of conditions of an ambient air comprising:
- a housing, said housing having a generally triangular configuration and including;
first, second and third lobes at corners of said housing;
perforations in a lower surface of said housing and at said lobes for passage of the ambient air therethrough;
a perforated central portion in said lower surface of said housing for passage of sound therethrough;
an alarm circuit in said housing comprising;
a power source for said circuit;
an alarm adjacent said central portion of said housing;
an air sensor in each respective lobe, each sensor causing a particular current flow to sound said alarm upon sensing a predetermined condition of the ambient air, the alarm sound passing through said central portion.

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.
