Fire Alarm System
Overview
A fire alarm system has a number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present. These alarms may be activated automatically from smoke detectors, and heat detectors or may also be activated via manual fire alarm activation devices such as manual call points or pull stations. Alarms can be either motorized bells or wall mountable sounders or horns. They can also be speaker strobes which sound an alarm, followed by a voice evacuation message which warns people inside the building not to use the elevators. Fire alarm sounders can be set to certain frequencies and different tones including low, medium and high, depending on the country and manufacturer of the device. Most fire alarm systems in Europe sound like a siren with alternating frequencies. Fire alarm sounders in the United States and Canada can be either continuous or set to different codes such as Code 3. Fire alarm warning devices can also be set to different volume levels. Smaller buildings may have the alarm set to a lower volume and larger buildings may have alarms set to a higher level.
General Fire Fighting Equipment
Fire fighting systems and equipment vary depending on the age, size, use and type of building construction. A building may contain some or all of the following features:
- Fire extinguishers
- Fire hose reels
- Fire hydrant systems
- Automatic sprinkler systems
- CO2 system
- Fire suppression system
The principle fire extinguisher types currently available include:
| The Principle for Fire Extinguisher
Extinguishing Agent |
|
| Water | wood and paper fires – not electrical |
| Foam | flammable liquid fires – not electrical |
| Carbon dioxide | electrical fires |
| Dry Chemical | flammable liquids and electrical fires |
| Wet chemical | fat fires – not electrical |
| Special Purpose | various (eg metal fires) |
- Fire extinguisher locations must be clearly identified. Extinguishers are colour coded according to the extinguishing agent.
