One embodiment of the present invention is a system for monitoring failure of a signal having lighting configured to indicate a predetermined alarm condition. The system includes 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 the detector/transmitter to a lamp socket of the lighting in an orientation in which the 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 the signal indicative of the lighting parameters to generate a signal indicative of predetermined fault conditions of the lighting.
