1. A detector for a fire related conditions including a component having a surface;
- wherein the surface includes, or is at least partially coated with a material having contaminant-resistant properties; and
wherein the material comprises a low energy material having a contact angle to water of greater than about 65 degrees in air;
the detector further including a contamination monitor disposed adjacent the surface, the contamination monitor configured to monitor an amount of contamination on the surface and to generate an output signal representing the amount of contamination; and
a removal enhancement device disposed adjacent the surface for aiding in the removal of contaminants from the surface, the removal enhancement device being operated in response to the output signal from the contamination monitor.

Abstract
A detector includes a component having a surface. The surface includes, or is at least partially coated with, a contaminant-resistant or self-cleaning material. This allows the detector to remain clean without manual cleaning.
