There are many factors to consider when installing fire alarm wire, raceways, boxes & cabinets comprising a fire alarm system. • Environments are wide-ranging and too numerous to identify. Please consult the International Building Code.Not mounting a hard wired smoke detector on a junction box would violate the NEC because you would have splices not in a box. You are being too alarmist about smoke detectors not mounting on a box. If it's hardwired, it will be compatible with standard single gang or light fixture box.BRK hardwired Smoke Alarms are designed to be mounted on any standard wiring junction box to a 4-inch (10 cm) size, on either the ceiling or wall. Read “Recommended Locations For Smoke Alarms” and “Locations to Avoid For Smoke Alarms” before you begin installation. Beginning at the first smoke detector box location, run 3-wire cable (with ground) to each subsequent smoke detector. The extra wire in these cables allows the smoke detectors to "talk" to one another, so that all detectors will sound the alarm when any of .
