A fire alarm system is an important component of fire protection and life safety equipment for all buildings. The system comprising both manually operated devices and automatic fire detectors contains alarm-signaling devices and a control unit. Some fire alarm systems are connected with automatic fire suppression systems. The fire detection and alarm systems are electrically interconnected in order to detect fire conditions and warn the occupants of the building and notify the fire department. A correctly designed, installed, and maintained fire alarm system is a main element in the protection of life safety. Automatic fire detection and alarm systems protect both life and property, as well as provide a warning of fire danger so that occupant evacuation and fire suppression activities can quickly start. Fire alarm systems vary from small to large and from basic systems that only sound audible fire alarm signals, to sophisticated that can easily expand including a variety of different building functions such as elevator recall, smoke control, electromagnetic locks release, etc. The building and fire codes state what type of building requires a fire alarm system to be monitored by transmitting alarm signals to a monitoring station or local Fire Department from protected premises. This provides an opportunity for the fire department personnel to respond to an emergency in a timely manner. Fire alarm system technologies constantly develop; therefore, it is crucial to stay up to date to ensure your fire protection and life safety systems are current and support all required functions of the building, herewith complying with all applicable codes and standards.
