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.
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 This requirement is superseded by strobe loca- tion requirements when an audible appliance is installed in combination with a strobe.
Fire alarm bells installed as part of an NFPA 72 fire alarm system should be mounted well above the head of an average person while leaving clearance between the bell and the ceiling. 18.4 Audible Characteristics. 18.4. 9 Location of Audible Notification Appliances for Building or Structure.
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.

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.
When a firefighter died in the line of duty, the fire alarm office would tap out a special signal. That signal was five measured dashes, then a pause, then five measured dashes, another pause…then five more dashes.
Eaton's motorised fire alarm bell for conventional fire alarm systems is available in two variants: indoor six-inch bell and weatherproof eight-inch bell. Bells remain popular choices for many non-fire applications including schools where it's used to signal class change and in factories to indicate a shift changeover.
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.
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.
It states that if the visual alarm is positioned too low it may not be seen, and recommends 2.1m as the minimum mounting height, but most applications would be higher than this. The British Standard also recommends that Fire Alarm Beacons aren't positioned any closer than 150mm from the ceiling.
Wall-mounted alarms should be installed not more than 12 inches away from the ceiling (to the top of the alarm).
Non-Sleeping Area Requirements
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.
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.
The centre of the element of the manual call point should be positioned 1.4m (+/-300mm) from floor level. Unless a wheelchair user is likely to be the first person to raise the alarm.

Fire alarm horns and bells serve to alert people during emergencies, each with unique features: bells emit loud, high-pitched sounds, while horns often include visual strobe lights for effectiveness in noisy settings. Understanding these differences is crucial for fire safety compliance.
If your smoke alarm is chirping or beeping regularly and you have verified that the battery is good, the fire alarm may be faulty, or it may be time to replace it. Many smoke alarms have a set life span of seven to 10 years due to the type of material used for the ionization process.

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.
Interconnected units must meet ALL of the following requirements: A maximum of 18 compatible units may be interconnected (Maximum of 12 Smoke Alarms). The same fuse or circuit breaker must power all interconnected units. The total length of wire interconnecting the units should be less than 1000 feet (300 meters).
The categories for life safety are LD1, LD2 and LD3.
LD3 requires detection on escape routes (usually stairs and lobbies), LD2 also requires detection in areas of high fire risk (usually kitchens and lounges) and LD1 requires detection in all parts of the building.
