One of the large EC's I've worked for in the area did a fire alarm job as a sub to another EC. This is somewhat unusual and the reason given for this is that the job specifications called for electricians (wiremen) to do the FA work.
Most of the time, at least around here, the EC has responsibility for the fire alarm, but will sub out the work to a FA specialist contractor who also just happens to work cheaper.
