I am looking for some help with wiring fire alarm systems. I am currently working on a 25 storey concrete high rise as a 3rd year apprentice and our fire alarm person has just left the company. For the present time I have been left to figure out how to continue the fire alarm sytem. Does anyone have any knowledge on Edwards Sytems and with their IDM, Siga MCC1, Siga MCC2 modules and their tone and page functions. I am currently pulling in my risers to each floor(to the idms) and want to confirm my sets of wires.
