Method and apparatus for light outage detection
First Claim
1. A system for monitoring failure of a signal having lighting configured to indicate a predetermined alarm condition, said system comprising:
- a detector/transmitter responsive to lighting parameters at least during the predetermined alarm condition to generate a signal indicative of the lighting parameters;
an attachment member configured to attach said detector/transmitter to a lamp socket of the lighting, said attachment member configured to attach to the lamp socket in an orientation in which said detector/transmitter assembly is responsive to light rays from a lamp mounted in the lamp socket when the lamp is on; and
a receiver/concentrator responsive to said signal indicative of the lighting parameters to generate a signal indicative of predetermined fault conditions of the lighting.
