NFPA 72 sets standards for the minimum and maximum mounting heights for fire alarm control units. The devices must be located between 1.5 and 5.5 feet above the finished floor to provide maximum accessibility.
The simple answer that the operable part of the pull station needs to be at least 42 in. (1.07 m), and not more than 48 in. (1.22 m), above the finished floor.

The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC powered and interconnected. See “Agency Placement Recommendations” for details.
NFPA 72 tells us how to properly install required strobe lights. It allows strobes to be installed on either the ceiling up to a height of 30 feet, or the wall between 80 and 96 inches. Personally, I prefer strobes on the ceiling because they are harder to obstruct.
NFPA 72 sets standards for the minimum and maximum mounting heights for fire alarm control units. The devices must be located between 1.5 and 5.5 feet above the finished floor to provide maximum accessibility. The recently revised standards make elevator recall and evacuation operations more specific.
Wall-mounted alarms should be installed not more than 12 inches away from the ceiling (to the top of the alarm).
A: Some of the key requirements of NFPA 72, National Fire Alarm and Signaling Code include: providing fire alarm systems that are designed, installed, inspected, tested, and maintained to meet the code's standards, providing fire alarm control units that are designed and installed to detect fires and initiate an alarm ...
According to NFPA 72, each pull station must be installed between 42 and 48 inches from the floor to ensure easy accessibility for people in wheelchairs. In addition, it needs to be placed in a location that's from free obstacles. This way any individual may access the pull station in the event of an emergency.
Installation of fire alarm panel shall be not exceed six feet in height measured from the floor to the top of the unit.
NFPA 72 requires that all points on the ceiling have a detector within a distance of 0.7 times the listed spacing of the detector.
In non-sleeping areas NFPA requires that wall mount visible notifica- tion appliances be installed such that the entire lens is not less than 80 inches and not greater than 90 inches above the finished floor.
NFPA 72 requires all fire alarm systems, including equipment used for monitoring, to have 24 hours of backup power. If an IP communicator is used for monitoring, the internet equipment must be connected to a backup power supply capable of providing power for a minimum of 24 hours.
The centre of the element of the manual callpoint should be positioned 1.4m (+/-200mm) from floor level (unless a wheelchair user is likely to be the first person to raise the alarm, when this is applicable it should be noted on any certification).
The bell should be mounted a minimum of 8 ft. from the floor or as close to the ceiling as possible.
How high should I mount a sounder/beacon? A standard sounder/strobe or individual strobe should be mounted 2.1m above the floor and not closer than 150mm from the finished ceiling.
The NFPA 72 or the National Fire Alarm and Signaling Code requires the manually operable part of the fire alarm system to be installed at a minimum height of 42 inches (1.07 m). The pull station height should not be more than 48 inches (1.22 m) from the finished floor.
Here, NFPA 72 height requirements are strobes must be installed 80 to 96 inches above the finished floor and 6 inches from the ceiling. Ceiling-mounted strobes are permitted on ceilings that are no higher than 30 feet.
Requirements for Fire Alarm Systems
The pull lever cannot require tight grasping, pinching, or twisting of the wrist. In addition, the pull lever should be within reach range or between 48 inches and 15 inches above the finish floor or ground.
Most fire alarm bells should be mounted at heights that place their tops above the floor at a height of at least 90 inches, or 7 1/2 feet, leaving at least 6 inches between the ceiling and the bell.
CO alarms should be installed in a central location outside each sleeping area and on every level of the home and in other locations where required by applicable laws, codes or standards. For the best protection, interconnect all CO alarms throughout the home. When one sounds, they all sound.
Placement. The code specifies that smoke detectors should be placed in every room, hallway, and storage area, with particular attention to sleeping areas in buildings with overnight accommodations.
Ceiling mounted: At least 4 inches from any adjoining wall surface. Wall mounted: Between 4 inches and 12 inches from the ceiling. Peaked or sloped ceilings: Within 36 inches of the peak or the high side of the slope, but no closer than 4 inches vertically or from an adjoining wall surface.
Among other things, the Foundation study recommends that NFPA 72 adopt the two equations as guidance for detector spacing for flat, smooth ceiling heights between 10 and 40 feet. Above 40 feet, the study recommends that the code require a performance-based analysis for detector spacing.
Have smoke alarms on every level of your home and in each bedroom and hallway. If you mount alarms on the ceiling, place them 4 inches from the wall. If your alarms are on the wall, they should be 4 to 12 inches from the ceiling. Don't install alarms near windows, vents, or drafty areas.
