Abstract:
A modular alarm-indicating and/or condition-sensing system comprising:a plurality of covers wherein each of the covers has a front wall and a peripheral skirt adapted to be positioned adjacent to a selected surface at which the respective cover is mountable wherein the front wall of each of the covers exhibits at least one common base-defining dimensional parameter defining an indented base region, wherein each of the covers defines an alarm signal-receiving region at least partially bounded by the peripheral base region and wherein each of the covers defines an alarm signal output port from which an alarm signal in the respective receiving region exits the cover and radiates into an adjacent exterior region;a plurality of alarm signal-indicating modules wherein at least two of the modules are different members of a group which includes an audible alarm generator, a visible alarm generator and a combined audible/visible alarm generator and are combinable with respective ones of the covers, each module mounted at least partially into one said indented base region of a respective cover to thereby form a plurality of covered modules each of which exhibits the at least one common base-defining dimensional parameter and;wherein respective ones of the covered modules are removably coupled to an electrical box and wherein respective ones of the alarm signal-indicating modules extend, at least in part, into the electrical box.
