Abstract
A smoke detector operational integrity verification system includes a plurality of electronic components. Also included is a controller in operative communication with the plurality of electronic components. Further included is an evaluation module of the controller receiving an output signal of the plurality of electronic components as an output voltage over a period of time, the output voltage measured at a plurality of times compared to predefined acceptable ranges.

A detector operational integrity verification system comprising:
- a plurality of electronic components;
- a controller in operative communication with the plurality of electronic components;
- and
- an evaluation module of the controller receiving an output signal of the plurality of electronic components as an output voltage over a period of time, the output voltage measured at a plurality of times compared to predefined acceptable ranges.
A method of verifying smoke detector operational integrity comprising:
- measuring a nominal output signal as a nominal voltage (VA), the nominal output signal generated by a plurality of optical and electronic components when a light emitting element is in an inactive condition;
- switching the light emitting element to an active condition;
- measuring a maximum output signal as a maximum voltage (VB);
- switching the light emitting element to the inactive condition;
- measuring a minimum output signal as a minimum voltage (VC);
- inputting at least one of the measured voltages into an algorithm stored on a controller;
- and
- comparing an algorithm output with a range of predetermined acceptable values to verify operational integrity of the smoke detector, the comparison done by an evaluation module of a smoke detector controller.
