Fire Alarm System

 A fire alarm is a unit made of several devices, which uses visual and audio signaling to warn people about a possible fire, smoke, or carbon monoxide occurrence in the area of coverage. Fire alarms are usually set in fire alarm systems to provide zonal coverage for residences and commercial buildings. The warning signal is either a loud siren/bell, a flashing light, or it can include both. Some fire alarm systems use additional warnings, such as sending a voice message or making a phone call.

Depending on the functionality and the integrated components, there are several classifications of fire alarm systems.

  • Automatic fire alarm systems are activated through fire detectors, such as smoke or heat sensors. Manual fire alarms are activated with manual call points or pull stations. There is no reason for a fire alarm system to exclude one or the other. You can include both in the same system.
  • Conventional fire alarms work as one unit, and are unable to pinpoint the exact area of activation unless inspected. 
  • Addressable fire alarms have a specially dedicated address for each fire alarm detector connected to the control panel for easier identification of the danger source.

SOLAR ENERGY

How Does Solar Work..... The amount of sunlight that strikes the earth's surface in an hour and a half is enough to handle the entire world's energy consumption for a year. Solar technologies convert sunlight into electrical energy through photovoltaic (PV) panels or mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage. Below, you can find resources and information on the basics of solar radiation, photovoltaic and concentrating solar-thermal power technologies, electrical grid systems integration, and the non-hardware aspects (soft costs) of solar energy. You can also learn more about how to go solar and the solar energy industry. In addition, you can dive deeper into solar energy and learn how the research department of  Solar Energy is driving innovative research and development in these areas.
