When installing pull boxes in a wall or ceiling, what is required for them?

When installing pull boxes in a wall or ceiling, they must be accessible. This requirement ensures that individuals can easily reach and operate the pull boxes during an emergency situation or in case of a fire alarm activation. Accessibility facilitates a rapid response to activate fire alarm systems, which is crucial for ensuring safety.

The term 'accessible' can typically refer to the requirement that the installation allows for unobstructed access to the pull box. This means that it should not be boxed in or hidden behind obstacles that could impede someone's ability to use it in an urgent scenario. The accessibility also considers the installation height and location, ensuring that it is within reach without special tools or aids.

Proper placement of pull boxes is vital to comply with codes and regulations, providing confidence that emergency personnel and building occupants can operate the fire alarm system effectively as needed.
