A smoke detector is a device that senses smoke. It is an indication of fire. These small security devices rings a signal that goes to a fire alarm control panel that is attached to a fire alarm system. These are small household smoke detectors that are also known as smoke alarms. If they detect a signal, they generally alert by ringing a local audible or visual alarm that is connected to the detector. Electrician Adelaide are generally quite skilled at installing these detectors on. Here are step by step instructions on how it can done on your own.
Smoke detectors are mostly put in plastic enclosures that are typically shaped like a disk which is about 150 millimetres in diameter and 25 millimetres in thickness. It’s shape and size does vary depending on various factors like where it needs to be installed and how audible it needs to be. Smoke can be easily detected by two ways:
- Optically or Photoelectrically
- Or by Physical Process also known as ionization.
Some detectors also use both the methods to detect the smoke. Sensitive alarms are also used to detect the smoke and they can easily inspect even the tiniest smoke and are therefore, used to detect and hence deter smoking in some areas where it needs to be banned. Smoke detectors in large commercial, industrial, and residential buildings are usually powered by a central fire alarm system, which is powered by the building power with a battery backup.
