Where must at least one telephone or jack be installed when into a telephone communication system is required?

When a telephone communication system is required within a building, it is essential for safety and effective emergency communication that at least one telephone or jack be installed in the fire pump room. This is particularly important because the fire pump room houses vital equipment necessary for fire suppression systems. Having communication equipment readily available in this area ensures that personnel can quickly relay information or call for assistance in the event of an emergency, such as a fire.

The fire pump room is usually a critical location where key decisions and actions regarding fire safety are made, and reliable communication is crucial to coordinating emergency responses. While it may be beneficial to have telephones in other locations, such as the main office or hallways, the fire pump room takes precedence to ensure immediate access to communication where it is most needed in emergencies related to the fire alarm and suppression systems.
