Bells make the fire alarm system. Without them to peal out the warning of danger on the horizon, there would be no point to a fire alarm system at all. A fire alarm system is designed with some kind of detector that picks up the slightest indication of smoke. It then passes this info to the control unit which will process it and activate the bells. The bells in turn notify people that there may be a fire. Other fire alarm systems do the same thing, but with horns.
That the unit has bells instead of anything else isn't really an issue in the protection the system will provide. It can work with bells, horns, sirens, or even strobe lights. It only matters that it's fully operational. Due to its importance, you need to make sure your system is always in good repair. Check it periodically with this in mind.
It is recommended that facilities which are capable of hosting 100 or more people be able to use the fire alarm bells most effectively. For larger or more complicated structures alarms with sirens and audio evacuation systems might prove more beneficial. Bells are often used for home applications, because they're loud enough to be heard all over the neighborhood.
Choices You Can Make
Companies which are world-renowned for their quality make fire beels. These companies include Wheelock Inc., Floyd Bell, Inc., Metalcraft, Euchner, and others.
You will have a few simple choices to make when buying or replacing fire alarm bells. One of these considerations is color of the bells. The general rule is to choose bells which match the cover set. However, they are also available in black, white, red, and a few other colors if you'd prefer a funkier configuration.
Size and specifications are two other things you will need to consider. Size is all about the internal size of the bell housing. Most of them are between 4" and 8" for home use and up to 12" for commercial applications. Specifications are the mounting and installation specs, the compatibility of the circuits being used, consumption, and cables for mounting.
The common range of most fire alarm bells is below 24 V. They, in turn, produce 75 dB of output sounds. When you go out to buy a set, it's a good idea to find one which is waterproof and which will withstand extremes weather conditions. By replacing your bells, you should be able to extend the use of your system for many more years.
