What happens to rate of rise heat detectors after they have activated the fire alarm?

Rate of rise heat detectors are designed to respond to a rapid increase in temperature, which occurs during a fire. Once a rate of rise heat detector activates the fire alarm system due to a detected temperature rise, it generally does not require replacement. These detectors are capable of returning to their normal state and can continue to function effectively after the activation. In most situations, as long as the detector is otherwise undamaged and not subject to other operational limits, it can remain in place and be reusable. The ability to not require replacement after activation highlights their durability and reliability in fire detection systems.

Options involving replacement or disabling do not reflect the functionality of these detectors accurately. Resetting might apply in some systems, but the characteristic of rate of rise detectors is that they can simply resume their function without needing a physical replacement or being rendered unusable.
