A fire alarm system using automatic fire detection or water flow detection devices must be equipped with_______ .

• A. At least two tamper switches
• B. An automatic test routine
• C. A building entry control device
• D. At least one pull station

Answer: (D)

When a fire alarm system relies on automatic detection or sprinkler waterflow to trigger alarms, there must still be a way for occupants to manually start the alarm. A manual initiating device, such as a pull station, provides that user-initiated input to the fire alarm control panel, ensuring the alarm can be activated even if automatic devices fail or if someone wants to alert others immediately. This redundancy helps ensure rapid notification and safety. The other options don’t fulfill this function: tamper switches monitor security but don’t initiate alarms from occupants, an automatic test routine is for maintenance rather than active activation, and a building entry control device is unrelated to initiating the fire alarm.
