In my area, sprinkler system tamper switches are always nippled to a standard 4-square box that simply dangles unsupported. This provides a junction point for the short lengths of wire leaving the tamper switches before being flexed to a nearby point in the fire alarm system. No AHJ has ever had a problem with this installation. I'm curious as to how this situation is handled elsewhere. Are hubbed boxes used as a better means of support by its connection via the nipple to the switch?
