ABSTRACT:
An air cleaner with a smoke alarm unit for a forced air recirculating system is disclosed. The smoke alarm unit is housed within a module that fits within the frame of the air cleaner with minimal impact on the cleaning ability of the cleaner. In a preferred embodiment of the invention, a battery capacity tester and air cleaner functionality detector are included in the module. Signals from the battery tester and functionality detector are used by the smoke alarm unit to drive an alarm generator with different signals to produce distinguishable alarms for a smoke condition, low battery condition, and an air cleaner failure. A control unit may receive any of the alarm conditions to execute different control actions in the forced air system.
