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.
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.
Preferably in an area of low fire risk and on the ground floor by the entrance used by the Fire Brigade and preferably viewable from outside of the building. It should be located in an area common to all building users and where automatic detection is in use, the Control Panel should be in a protected area.
NFPA 72 sets standards for the minimum and maximum mounting heights for fire alarm control units.
