FIRE ALARM SYSTEMS
- Control panel – monitors input and system integrity and controls output and sends information.
- Power supplies – both primary and secondary (back up) are needed.
- Initiating devices – these are the components that indicate there’s a fire. There are two types:
• Automatic: These are detectors that can measure smoke, heat, CO2 and flame.
• Manual: These require a person to initiate them. Examples include pulling stations and alarm buttons.
- Notification appliances – these alert building occupants to fire. For example, sirens, speakers, and flashing lights.
- Building safety interfaces – these are things that help people exit the building safely, such as exit lighting and ventilation systems that redirect toxic smoke.
