Abstract: A scent alarm device which includes a housing and a spray canister of an odorant, such as butyl mercaptan, supported within the housing utilizes a mechanism for intermittently dispensing odorant from the canister upon the occurrence of a predetermined event. The spray canister has a depressible release valve for releasing canister contents upon depression of the valve, and the depressing mechanism is adapted to repeatedly depress the canister release valve in an intermittent fashion. The device may utilize a canister having a height within a range of canister heights, and if desired, the device may be interfaced with a number of other alarm systems, such as a smoke or heat detector or used to alert an individual that household electrical power has been shut off.
