As defined by the NFPA, the location of a wall-mounted audible appliance shall have their tops not less than 90 in. above the floor and not less than 6 in. below the ceiling. This requirement is superseded by strobe loca- tion requirements when an audible appliance is installed in combination with a strobe.
The minimum mounting height of a visual notification appliance listed for ceiling mounting shall be 80 in. (2.03 m) above the finished floor or the actual ceiling height, whichever is less.
The height of the visual alarms shall be between 2m to 3m above finished floor level. (3) Visual alarms shall comply with all the following requirements: (a) They shall take the form of a flashing beacon or strobe light for use in conjunction with the conventional fire alarm system.
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.
What is the required height for a fire alarm pull station? 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.
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.
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.
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.
Where should a fire alarm panel be located? Indicating equipment, in conjunction with suitable manual control facilities, should be sited at an appropriate location for both staff and firefighters responding to a fire signal, such that controls can be readily operated and indications are readily visible.
The height of the manual fire alarm boxes shall be not less than 42 inches (1067 mm) and not more than 48 inches (1372 mm) measured vertically, from the floor level to the activating handle or lever of the box.
A correctly orientated plan of the building must be displayed close to the control panel showing entrances, escape routes and zones. Fire alarm panels (standard Kentec) with LCD display should be mounted such that the top of the panel is at 1.65 metres +/- 0.1 metres above floor level.
Wall-mounted alarms should be installed not more than 12 inches away from the ceiling (to the top of the alarm).
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.
Carbon monoxide is lighter than air. It also rises with warm air, so the United States Environmental Protection Agency (EPA) recommends placing a carbon monoxide detector on a wall about five feet above the floor or about eye level. You can put them on the ceiling, too.
Please note that the minimum mounting height for a wall category device is 2.4m.
What height should a fire alarm pull station be installed? All fire alarm pull stations need to be installed anywhere from 42 to 48 inches from the floor.
Installation of fire alarm panel shall be not exceed six feet in height measured from the floor to the top of the unit. Exception: Suppression system releasing panels are not required to meet the height requirement or the limitation in the number of panels.
Alarm systems required to be accessible by 4.1 shall comply with 4.28. At a minimum, visual signal appliances shall be provided in buildings and facilities in each of the following areas: restrooms and any other general usage areas (e.g., meeting rooms), hallways, lobbies, and any other area for common use.
Not less than 150 mm from the ceiling measured from the top of the assembled device (top edge of gong if the device is a bell). Not less than 2300 mm above the floor (where ceiling heights allow) measured to the centre of the device.
A Break Glass Call Point is a device which enables personnel to raise the alarm by breaking the frangible element on the facia. They should be mounted 1.4m from the floor and sited where they can be easily seen. Manual Call Points should be sited on the floor landings of stairways and at exits to open air.
A minimum of 36-inches clearance in front of the panel must be maintained from the floor to 6-feet, 6-inches above the panel, or to the top of the panel whichever is highest. A minimum of 30-inches clearance from side to side must be maintained in front of the panel.
The standard height for an alarm system keypad is probably around 4.5 feet high. However, anywhere from 4 to 5 feet up is usually okay. It really comes down to the height of the end user and what they feel most comfortable with. Some users will mount it higher, and some will mount it lower.
9.1 If ceiling heights allow, and unless otherwise permitted by 18.4. 9.2 through 18.4. 9.5, wall-mounted appliances shall have their tops above the finished floors at heights of not less than 90 in. (2.29 m) and below the finished ceilings at distances of not less than 6 in.
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.
The control panel should be mounted on a dry, flat surface, at eye height to the display and in a level position such that the enclosure is not distorted.
