How do Fire Alarms Work?

Until now, most installations during the phase of construction be it for the purpose of industrial, commercial or residential, have all used wired fire detection systems. These systems are usually installed at the time of construction which makes cable laying an easy proposition. However, today we are seeing a paradigm shift in all applications and wireless technology has become an essential part of our lives.

When wireless technology is added to existing products, the result is usually a quantum leap ahead in functionality. Many critical installations such as fire detection and alarm systems are slowly turning wireless. Wireless or radio fire alarm systems came into existence in the 80s. Today these systems are light years ahead of their ancestors in terms of features, performance, reliability and cost.

Wireless fire alarm systems utilize secure, radio frequencies to connect the sensors and the various devices such as call points, smoke detectors, sounders, etc. with the controllers, without the use of cables or expensive installation costs. The wireless fire alarm systems are connected to each other wirelessly and when one smoke alarm goes off then all of them do.

Gradually the trend is turning towards installing wireless systems where laying cables is expensive, time consuming or impractical. Wireless fire alarm systems are especially great for temporary installations. Wireless systems are the perfect solution that is cost effective and offers a high level of flexibility.

Pros of Choosing Wireless Fire Alarm Systems

  • Wireless fire alarms are easy to install anywhere and the main advantage is the portability of the system. These systems can be installed anywhere and moved whenever or wherever required. These wireless devices can be positioned and reused whenever required and this can be done very quickly too.
  • There is no need to run cables to connect every device to the fire alarm system.
  • The installation times are vastly reduced as there is not much cabling to be done. A single device can be installed in just under 30 minutes while the hard wired system could take weeks or months to install. This also helps to minimize the impact on your business caused due to delays in installation.
  • If you are changing the layout of your site project, you can change the position of your wireless fire alarms very easily.
  • As the wireless systems run on batteries, there is no need to connect the system to a power grid. Also, in case the power goes off, your fire alarm system will continue to run without any interruptions.
  • Wireless fire alarm systems can also be used as temporary installations, for example at construction sites where fire alarms are required when the work is going on and can be dismantled once the work on the site is completed.

Worth Considering:

  • Since the wireless fire alarm systems run on batteries, they will need to be checked and replaced at regular intervals.
  • These wireless systems have range restrictions and in case of large areas, the wireless system may have issues when transmitting to the main control panel. Therefore, you would need to install multiple wireless fire alarms in order to cover the entire premises, as well as to comply with legislation.

Wireless technology is slowly but surely becoming a way of life and a part of modern businesses as well as homes. There are many advantages of choosing wireless fire alarm systems over a traditional wired ones and the progress in technology has made them as reliable and dependable as wired fire alarms, if not more.
