BAM becomes early adopter of Bull Products’ Cygnus fire alarm system

A division of BAM, one of the UK’s foremost construction groups, has installed the Cygnus wireless fire alarm system from Bull Products at over 10 construction sites since the solution was launched in May 2014.

One of these projects is a new development for Hayes Retail which incorporates an Asda supermarket boasting 8,000 square metres of floor space and including car park and petrol filling station.

Due to the large site footprint and separate office and welfare complex, the project management team at BAM Fire Protection Services opted to install the Cygnus system as the temporary fire alarm system.

Mike Whitfield, the contracts manager at BAM Fire Protection Services, was so impressed with the development of the new Cygnus system that he, along with the Health and Safety Department, has put the system forward under Safety Best Practice to the entire BAM London region as a recommendation for all BAM site managers, project managers and Health and Safety officers.

Whitfield explained: “We were looking to adopt a wireless fire alarm system within the group. We particularly like the Cygnus system’s addressability, and Bull Products also integrated a First Aid alert within the Call Point which satisfied our needs.” Bull Products is now working on a future option for controlling panels on a remote basis.

Linking 480 units in 15 zones

Launched only two months ago, the Cygnus wireless fire alarm system can linkno less than 480 units in 15 different zones around a construction site, with each zone having the capacity to accommodate 32 units. The individual units can be fire alarm Call Points, First Aid alert points, smoke detectors, heat detectors and a combined Call Point-First Aid alarm. The alarms – which can be used “time and again” – are addressable to the panel and may be re-addressed very simply after being relocated.

Intended purely for use on construction sites, the Cygnus system has been specifically designed for deployment in dense concrete and steel-structured buildings and areas where there are many other radio frequencies in operation. On that basis, particular attention has been given to achieving an impressive connection range. Where there are multiple sites within range of each other, the Cygnus system has been designed to operate on different site addresses in order to keep each system separate and free from interference.

A major feature of the Cygnus system is the optional control panel which provides a very sophisticated capability with an event log function which records any events such as an alarm activation, low battery warning and signal faults, all of which can be viewed if necessary in the history folder held on the panel.

The system also has the ability to test all units and has an evacuate function which will act as a Call Point to the rest of the alarm units.

Each unit in the system can provide the panel with information at regular intervals. This explicit information confirms the unit is still present and what the battery status of each device is at the time. Known as the ‘heart beat’ this message is monitored by the control panel where fitted and, if the ‘heart beat’ is not heard for several intervals, the control panel logs a full status for that unit.
