Wireless technology is now an everyday part of our lives, both at home and in the workplace - having radically changed the way we work and communicate. Parallel advances in battery technology and electronic components that operate at much lower voltages and power levels have helped to make this possible.
Safety critical installations such as fire detection and alarm systems often require large numbers of field devices to be fitted which, for reasons of integrity and lifetime cost of ownership, are still preferred, specified and will remain as hardwired types for the foreseeable future. It is therefore clear that there is a place for both types of technology 'wired' and 'wireless' when designing and specifying a fire detection system. Wired devices should be used where cables are easy and cost effective to install, and wireless devices should be used where the installation of cables would be expensive, time consuming, impractical or just impossible.
