FIRE & ELECTRICAL SAFETY
ALARMINGLY GOOD SAFETY AT LORD’S
When a spectator stand at Lord’s Cricket Ground needed to be refurbished, the Cygnus fire alarm system from Bull Products was chosen to ensure the visitors’ safety.
One of the key spectator stands at Lord’s Cricket Ground is currently under a two-stage development programme and, during construction works, Bull Products is providing its Cygnus wireless fire alarm systems.
The Warner Stand, which was built in 1958, is being replaced with a new stand with seating for 2,656 spectators with improved sight lines to the pitch, and at the same time incorporating a new restaurant, three bars and catering facilities. The sustainable design features ground source heat pumps, photovoltaic roof panels, rainwater harvesting and a semi-translucent fabric roof.
Phase one of the Warner Stand project focused on the structure and seating of the stand before handing over in July 2016 ready for the second England v Pakistan Investec Test match. With the cricket season now over, the phase two work of creating bars, restaurant and other amenities has now started and is due for completion in April 2017.
Although designed as a temporary alarm system for construction sites, the Cygnus wireless system can be used on other construction sites after use. On the Warner Stand project, the flexibility of the system was underlined when it was able to be modified to link with alarms in the construction site offices. It was also modified to interface with the general alarm system at Lord’s.
The Cygnus wireless fire alarm system is a major innovation for construction sites and has been designed and developed in conjunction with major construction companies to incorporate all the features required for larger construction projects. The Cygnus system is able to link no less than 480 units in 15 different zones. Individual units may be a fire alarm call point, first aid alert point, smoke detector, heat detector or a combined call point and first aid alert alarm.
Where there are multiple sites within range of each other, the CE marked 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.
For both phases of this work, BAM Construction specified Bull Products to supply and install five Cygnus wireless fire and first aid alarm call points and 31 smoke detectors. Fire point stations are positioned throughout the site with alarms that are linked to a main control panel. This control panel is also linked to an additional sounder system which can be switched off on match days.
Kevin Stoney, Project Manager for BAM London, said: “The Cygnus system performs really well and is very reliable. Bull Products respond well to any requests, and all regulations were successfully signed off to allow a smooth hand-over.”

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. 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.
A PIR option is now available on any of the modules which can detect an intruder and alert off-site personnel for added safety protection.
