Different Types of Fire Alarms
If you're shopping for a suitable fire alarm, there are many things to be considered. However, the first step would be to identify the particular type of alarm you need. As you know, there are many out there, but they are not all created equal.
To know which fire alarm is best for you, know the different types available. You can visit the link for details about this. Note that fire alarms are mainly differentiated by the smoke sensors they use.
For example, for a business setting like warehouses or laboratories, air sampling smoke detectors are recommended because they are more sensitive to smoke. They have a sensor within a group of pipes that have air running through them. The sensor works by determining whether or not there is smoke.
Photoelectric smoke detectors from fire alarm companies in toronto have photoelectric alarms, where a small strobe of light stays lit until there are smoke particles detected. If the alarm senses a smoke particle, light is diffracted and the alarm is set off. Photoelectric smoke detectors are very expensive, but they are less prone to accidental tripping. These alarms also work best in detecting bigger smoke particles coming from electricity or fabric-sourced fires.
A smoke detector that comes with an ionization alarm makes use of very small amounts of the radioactive element, americium 241. This is what ionizes the air inside the alarm. The process of ionization creates an electric current inside the detector. As soon as smoke particles make it to the ionization chamber, the current is disturbed and the alarm sounds off. Sometimes, ionization smoke alarms are used in combination with carbon monoxide detectors. They're also perfect for detecting practically invisible smoke particles from fires that begin abruptly, such as those created by grease or paper.
Finally, a dual sensor alarm combines the best of photoelectric and ionization processes to provide the most reliable smoke detection system. More about this are explained at http://www.ehow.com/list_6692257_types-fire-alarm-systems.html. Alarms using these two systems are usually more expensive than those that only use a single smoke alert type, but they can detect all smoke particles, big or small. One may also purchase photoelectric alarms and ionization alarms separately and enjoy the same benefit.
Whatever type of alarm you choose, what's important is that you've done your research. And of course, you have to make sure that you're buying a system that is known for reliability. The Internet is a great place to find information about certain available systems in the market. By reading the testimonials posted by past customers, you can have an easier time which option is best for you.
