The Development of Site Fire Alarms

Of all the fire safety products on the market, reliable fire alarms are the critical first step in alerting people of the danger and saving lives in the event of a fire.

The HSE states that the aim of any fire warning system is to ensure that people on site are alerted to make their escape before a fire becomes life-threatening. The essential requirements of the fire warning signal are that it is distinctive, clearly audible above any other noise, and is recognised by all the people on site.

Site fire alarms have come a long way over the years and every business should ensure they have an alarm on site to protect workers and their site during the construction phase.

The history of the fire alarm

The very first fire alarm was invented by Dr.William F. Channing (supported by Moses G. Farmer). They adapted the principle to develop the first city-wide telegraph fire alarm system in Boston, US in the 1850’s – it was the start of a series of technological developments that would help protect property and save lives.

Channing and Farmer’s revolutionary fire alarm telegraph system enabled communication between a series of telegraph alarm boxes and a central alarm station. Each box had its own signal, enabling the central office to identify the location of the incident – though as the system was not automated, it relied on an individual to trigger the alarm to summon help.

Now as technology has advanced, it has enabled fire alarm systems to work wirelessly, and use a range of communication technology to send a fire alarm signal direct to the nearest fire service to request firefighting support.

A major innovation in wireless emergency fire, first aid and intruder alarms for construction sites, our Cygnus Wireless Alarm System is designed to offer the ultimate in performance and reliability.

Site Evac Fire Alarm with Radio Link

Designed to handle even the harshest weather conditions, this site fire alarm is robust and resistant, making it the ideal alarm for construction sites.

This multi-purpose and compact alarm can be activated manually and can be used as a stand-alone product for smaller areas. Or, for complex buildings and sites, it can be connected wirelessly or by cable to a network of heat and smoke detectors, without the need for a control panel. When used in this way, the site fire alarm becomes automatic and is triggered as soon as one of the detectors senses rapidly increasing heat or smoke.

Once activated, the Site Evac Fire Alarm emits a red flashing light and a warning noise with an output of 110 decibels.

This alarm has become renowned in the construction industry due to its extremely robust casing that allows it to be used in outdoor or exposed locations.

It can be attached to a mains supply or operated via batteries. Once activated, the site fire alarm features a flashing strobe light and a sound output of 115 decibels.

The main use for this type of system is in multi-story apartments or complex buildings where multiple exit routes may be used.
