I need help with a shunt type masterbox. I want to wire an initiating device (pulls and/or heats) directly to the shunt loop. The problem is that many of the devices are NO and close on alarm, the shunt loop for the gamewell box is Normally closed and opening the loop causes the box to trip. Are there any normally closed FA devices? Or could I use a relay? Anybody have experience doing this?
Can anybody supply part numbers or recommend products do do this?
This is for a display, it is not a life safety system.
I do run a LARGE 100 mil system on my property with 3 circuits covering my one acre of land with 8 fire alarm systems, each with its own gamewell masterbox. The systems are spread between my house and two sheds. Image
