Are all fire detection devices required to be listed or approved for their intended use?

Fire detection devices are indeed required to be listed or approved for their intended use. This requirement ensures that the devices meet specific safety standards and have been tested for performance by recognized testing laboratories. The listing signifies that the device has been evaluated for its effectiveness in detecting fire and providing reliable alerts in the event of an emergency. This is crucial for maintaining safety in buildings and ensuring that the fire alarm system functions correctly during a fire incident.

While there may be nuances based on local codes and regulations, the overarching principle is that to ensure consistency and reliability in fire safety measures, all devices should be approved for the specific environments in which they will be used. Choosing devices that are not listed or approved can lead to failures in detection and response to fire hazards, ultimately compromising safety and increasing the risk of property damage and loss of life.
