Method and apparatus for light outage detection

A system for monitoring failure of a signal having lighting configured to flash during a predetermined alarm condition, said system comprising:

• a power supply configured to power the lighting during the predetermined alarm condition and to provide a timing signal indicative of power being applied to the lighting;
• a detector/transmitter responsive to the timing signal to detect lighting parameters when the lighting is flashed on to generate a signal indicative of the lighting parameters;
• an attachment member on which said detector/transmitter is mounted, said attachment member configured to attach onto a 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.

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 screw into a lamp socket of the lighting and having an adapter socket configured to accept a lamp of the lighting, said adapter socket configured to supply power to the lamp when said lamp socket is powered and to attach said detector/transmitter to a lamp socket of the lighting 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.

A system for monitoring failure of a signal having lighting configured to indicate at least one predetermined signaling condition, said system comprising:

• a plurality of detector/transmitters responsive to lighting parameters at least during the predetermined alarm condition to generate signals indicative of the lighting parameters;
• an attachment member for each said detector/transmitter, said attachment member configured to attach said detector/transmitter to a lamp socket of the lighting, and 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;
• wherein said signal comprises a plurality of lamps and said system comprises a plurality of said detector/transmitters, and wherein each said detector/transmitter is configured to provide a unique detector identification number to the detector/transmitter and an identification of a position of each lamp monitored by said detector/transmitter.
