What type of fire alarm system is activated by a tamper proof switch?

A Class B fire alarm system is designed to provide protection over a specific area while allowing for the integration of tamper-proof switches. These switches are used to prevent unauthorized manipulation of the fire alarm system components, ensuring that the system remains functional and effective in the event of a fire. Class B systems typically utilize a two-wire configuration that supports the connection of multiple devices, including smoke detectors, manual pull stations, and other alarm signaling devices.

The use of a tamper-proof switch adds an additional layer of security by ensuring that anyone attempting to disable or interfere with the system will be met with an alarm or notification. This design is particularly beneficial in environments where unauthorized access may be a concern, enhancing the overall reliability and performance of the fire safety measures in place.

Other system classes, such as Class A, C, and D, do not typically emphasize the tamper-proof feature to the same extent as Class B, focusing instead on different aspects of fire safety and system configuration.
