Fire Alarm Systems | Residential | Ener-Tel ServicesDavid Herres Dec 01, Even if you're not ready to take the plunge into fire alarm system design and installation just yet, you should still know the fundamentals in order to perform emergency work. This includes knowing how to disarm the control panel of a deranged system and troubleshoot the heads, pull stations, horns, and zone wiring so that the equipment goes back online, restoring fire protection for the building. Because these ailments can be frequent with older and newly commissioned systems alike, it's important for electrical contractors to understand the basics of fire alarm systems. The modern fire alarm system is capable of detecting smoke and heat from a small flame, water flow in a sprinkler system or an activated pull station, and reporting this information to on-site personnel via dedicated phone line to any location in the world. Although a seemingly straightforward device from an installation standpoint, fire alarm work can be quite complex, especially when you consider the enormous moral and legal responsibilities involved. There have also been some recent updates to the technology over the last few years worth noting.

Before you decide to replace an antiquated fire alarm, you should know about the different types of fire alarm systems on the market. The two main types of fire alarm systems are conventional and addressable. The various components that make up these systems are either automatic or manual. Conventional fire alarm systems and its components are all wired to the same cable that connects them to a fire alarm control panel. The control panel displays a signal when these components activate. These types of systems are inexpensive and work well in small facilities. The main problem with conventional fire alarm systems is that when a fire alarm component produces a signal and it appears on the control panel there is no way to know which component it is in the building.
