Wireless Fire Alarm Reduces Installation Time
By Arthur Sneddon

In many older buildings as well as those in which wiring presents some real challenges, companies are turning to a wireless fire alarm to provide protection. Building construction may not lend itself to be friendly towards the installation of wires that a typical installation would require, and a wireless fire alarm can help speed up installation.

For example, in some older commercial structures running wires through walls to connect fare sensors may require going through wall that are up to two or three feet thick. They may also be made of steel or heavy concrete requiring drilling and inserts being placed in the wall to prevent a breakdown of firewalls. A wireless fire alarm can place the sensors in a matter of minutes instead of possibly hours, or even days.

Another advantage of the wireless fire alarm is that sensors can operate on slightly different frequencies to still provide notification as to which sensor has been activated. Several may still be on the same frequency to reduce the number of receivers needed for the installation, but the size of the receivers has been reduced to the point where several can be used in one location.

Environment May Cause Need For Mixed System

There may be some environments that prevent the use of a wireless fire alarm such as buildings with walls too thick or made of materials that prevent the wireless transmission from reliably getting through. Distance is also a factor, although inline amplifiers and repeaters can help solve distance problems. There may be a need to install a system that utilizes both wired and wireless fire alarm components to provide reliable notification in case of a fire.

A system can be wired through normal installations and wireless fire alarm parts installed where wired installations presents too much of an issue to be installed in a timely manner. Even in some residential installations, wireless components may be a better option, for instance on the top of a high wall made of stone or brick. Drilling through the medium for a wire run may damage the surface or substrate and take considerable time to accomplish.

A typical wireless fire alarm can easily be connected through one panel, and without the need for cutting or drilling to place heat sensors, an average one-story home can most likely be completed in less than one day. A commercial installation about the same, depending on the number of sensors being installed.
