In order to provide a basic level of safety, every level of a home should be outfitted with a wireless fire alarm. Wireless fire alarms are either self-contained devices, part of a series of interconnected units or one component of a larger fire/home security system. Whatever is the case, there are 2 basic types of wireless fire alarm: photoelectric and ionization. Photoelectric units detect visible particles, while ionization fire alarms detect invisible heat particles. Used together, the outbreak of fire will be quickly detected.
Benefits of Wireless
Hardwired fire alarms can involve a lengthy installation process. Hardwiring each component to a circuit is time consuming and may require extensive retrofitting. Not only that, but should the power fail, a wired fire alarm must then rely on its backup battery for operation. Wireless fire alarms, by contrast, are battery powered and emit a continual chirp when the battery needs replacing. Long-term, 10-year batteries are also useful for wireless fire alarms.
Independent wireless fire alarms are fairly common. If fire is detected, the single device sounds the alarm. An interconnected system of wireless fire alarms are linked by radio signals. If one goes off, they all do. Lastly, a wireless fire alarm may be a part of a more complex security system. If it detects fire, a signal is sent to the control panel which directs the automatic voice dialer to notify the authorities.
