What are Fire Alarm Devices?
Fire alarm devices (also known as fire safety devices) detect signs of fire or alert building occupants so they can respond and evacuate safely.
Definition
Purpose
Fire alarm devices are the core components of a building's fire alarm system. Based on their type, fire alarm devices behave differently. Some devices detect conditions such as smoke, heat, or water flow, while others allow people to activate an alarm manually. Notification devices then provide audible or visual warnings to occupants.
These devices communicate with the fire alarm control panel to help the system detect an emergency and initiate the appropriate response.
Examples of Use
- Smoke detection: Smoke detectors can sense smoke and send a signal to the fire alarm control panel to initiate an alarm sequence.
- Manual activation: Manual pull stations are typically installed near exits so occupants can activate the fire alarm while exiting the building for their safety.
- Occupant notification: Strobes and other notification appliances provide visual warnings, particularly where audible alarms alone may not reach or adequately alert occupants.
Notes
- Common fire alarm devices include: Smoke detectors, heat detectors, manual pull stations, water-flow switches, duct detectors, strobes, and audible notification appliances.
- Fire alarm devices are initiating devices that provide system inputs, and notification appliances alert occupants.
- Device placement and coverage depend on the building's design, applicable codes, and the type of fire alarm system.
