Combination airborne substance detector
DCFirst Claim
1. A combination airborne substance detection apparatus comprising:
- (a) an enclosure;
(b) a first module disposed within said enclosure for detecting the presence of a quantity of a primary airborne substance;
(c) a second module disposed within said enclosure for detecting the presence of a quantity of a secondary airborne substance; and
(d) an alarm module capable of producing a first perceivable emission when said primary substance is detected and for producing a second perceivable emission when said secondary substance is detected, wherein when said primary and secondary substances are at least one of simultaneously or near simultaneously detected said first perceivable emission is implemented first and includes continuous audio and visual emissions followed by implementation of a non-audio second perceivable emission;
wherein said first and second detector modules are each capable of independently and continuously detecting said primary and secondary substances, respectively.

Abstract
A combination airborne substance detection apparatus includes an enclosure, a first module disposed within the enclosure for detecting the presence of a quantity of a first airborne substance, a second module disposed within the enclosure for detecting the presence of a quantity of a second airborne substance, and an alarm module for producing a first perceivable emission when the first substance is detected and for producing a second perceivable emission when the second substance is detected. The first perceivable emission includes at least one of an audible and a visible emission that is distinguishable from the second perceivable emission. The first and second detector modules are each capable of independently and continuously detecting the first and second substances, respectively.
