In addition, the pull lever should be within reach range or between 48 inches and 15 inches above the finish floor or ground.
If the path to the ADA-compliant fire extinguisher or pull station is unobstructed, the operable part must be placed from 15 inches to 48 inches off of the finished floor or ground. But when the wheelchair user must reach over an obstruction, these heights may change.
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. Additionally, one pull station needs to be within 5 ft (1.5 m) of each exit doorway on each floor where required to be installed in a building.
NFPA 72 requires a pull station within 60 inches of every individual exit, and for groups of doors that are more than 40 feet wide away from each other, there must be a pull station on both sides of the grouping. The placement of fire alarm pull stations is critical to ensuring they provide the protection intended.
Under the ADA, accessible fire alarms are required in public and common use areas, transient lodging, and residential facilities; visible fire alarms must be installed in employee work areas. Any area open to the public must comply with the ADA standards for accessible fire alarm systems.

National Fire Alarm and Signaling Code®
NFPA 72 provides the latest safety provisions to meet society's changing fire detection, signaling, and emergency communications demands.
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 ...
In an emergency, anyone can pull the station's handle or lever to trigger the fire alarm system, which activates audible and visual alarms throughout the facility. This immediate alert system helps ensure a rapid evacuation and alerts emergency responders to the location of the emergency.
NFPA 13 covers the installation of fire sprinkler systems; NFPA 72 covers equipment related to fire alarm systems.
NFPA 1500 specifies the minimum requirements for an occupational safety and health program for fire departments or organizations that provide rescue, fire suppression, emergency medical services, hazardous materials mitigation, special operations, and other emergency services.
Pull stations are typically located near exits or in easily accessible areas. In emergencies, time is of the essence, so accessible, visible fire alarm pull stations facilitate a rapid response from building occupants and emergency services.
If you want your pull station to be pulled only in case of emergency, you need powerful manual pull station cover protection. Just like Sigcom manual pull stations, SENTRY™ Pull Station Covers are the industry standard for keeping manual pull stations safe from weather, vandalism and environmental damage.
When installing a pull station, it is always best to install the electrical box at 48 inches to the top of the box, so regardless of the type of pull station, you will always be within mounting limits. Pull stations must be installed so the operable part is between 42 inches and 48 inches above the finished floor.
Handles, Pulls, Panic Bars
Door Hardware – ADA compliant locks, exit devices, handles, pulls, latches, and other operable parts on doors shall comply – Operable parts of such hardware shall be 34 inches minimum and 48 inches maximum above the finish floor or ground.
Do not obstruct access to and visual contact with the fire alarm pull station. There must be a minimum of 36 inches of clearance, in a semi circle shape, from the pull station.
The pull station height should not be more than 48 inches (1.22 m) from the finished floor. Apart from this, one fire alarm pull station should be installed within 5 ft (1.5 m) of the exit doorway of the building. With buildings with multiple floors, this applies to each floor of the building or facility.
Both MCP and MPS have Emergency Release and Abort Release but MPSs have Lift and Pull added feature and MCP has light indication feature. These devices are corrosive-free pre-painted plates inherited on the surface that keeps away from corrosion.
Although there are no legal installation requirements for fire suppression systems, property owners, be they commercial or residential, are responsible for arranging experts to conduct fire risk assessments. This assessment, whether conducted internally or externally, may reveal the need for a fire suppression system.
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.
Section 4-4.4. 3.2 of NFPA 72 requires a minimum 110-candela appliance to be mounted on a wall not less than 24 inches from the ceiling, or a 177 cd appliance if mounted less than 24 inches from the ceiling. The higher intensity is required in case there is a smoke layer, which could attenuate the signal.
Two key National Fire Protection Association (NFPA) standards for the ITM of fire safety systems are NFPA 25, which is the standard for Water-Based Fire Protection Systems, and NFPA 72, which is the standard for National Fire Alarm and Signaling Code.
Additionally, pull stations are required to be located within 5 feet (1.5 meters) of each exit doorway on every floor, ensuring they are easily reachable during emergencies. Some commercial buildings may have additional requirements to ensure compliance with building codes and fire protection standards.
For many years NFPA 72, National Fire Alarm and Signaling Code, has required as a minimum that smoke alarms be installed inside every sleep room (even for existing homes) in addition to requiring them outside each sleeping area and on every level of the home.
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.
