02-385 C.M.R. ch. 920, § I - Fire Detection Equipment

All manufactured homes, regardless of the date of manufacture, shall meet the following requirements. They are:

1. At least one smoke detector (which may be a single station alarm device) shall be installed in the home in the following locations:

A. A smoke detector shall be installed on any wall in the hallway or space communicating with each bedroom area between the living area and the first bedroom door unless a door separates the living area from that bedroom area, in which case the detector shall be installed on the living area side as close to the door as practical. Homes having bedroom areas separated by any one or combination of communication areas such as kitchen, dining room, living room, or family room (but not a bathroom or utility room) shall have at least one detector protecting each bedroom area.

B. When located in hallways, the detector shall be between the return air intake and the living area.

C. The smoke detector shall not be placed in a location which impairs its effectiveness.

D. Smoke detectors shall be labeled as conforming with the requirements of Underwriters Laboratory Standards No. 217, Third Edition, 1985, as amended through October 8, 1985, for single and multiple station smoke detectors.

E. Each smoke detector shall be installed in accordance with its listing on a wall or ceiling. If installed on a wall, the top of the detector shall be located 4 inches to 12 inches below the ceiling. However, when a detector is mounted on an interior wall below a sloping ceiling, it shall be located 4 inches to 12 inches below the intersection on the connecting exterior wall and the sloping ceiling (cathedral ceiling). The required detector(s) shall be attached to an electrical outlet box and the detector connected by permanent wiring method into a general electrical circuit. There shall be no switches in the circuit to the detector between the over-current protection device protecting the branch circuit and the detector. The smoke detector shall not be placed on any circuit protected by a ground fault circuit interrupter.
