ABSTRACT:
A smoke detector which includes a cover that is attached to a housing base by a mechanical latch. The housing contains a fan that induces an airflow through the housing, a smoke detector that can detect smoke in the airstream, and a flow sensor that can measure the flowrate created by the fan. The flow sensor and fan can be captured by plates that slide into inner walls of the housing and are secured by the cover. The cover also has a latch for securing a grill to the smoke detector housing.
