Protec was set with the task to design-develop a full BS5839 and HTM05-03 compliant fire alarm system which would also work alongside a fire damper system which prevents the spread of fire. The system would need to offer a full graphical representation of the building for control/ integration of the fire alarm system an have a voice evacuation capability to reduce the risk of alarm and distress in a fire scenario.
A Protec Algo-Tec™ fire detection system was installed protecting the staff, patients, visitors and buildings from fire.
The fire alarm system is monitored by several main fire alarm control panels, with a further 142 Protec Algo-Tec™ 6000 LCD loop driven panels located out in the field at specific nurse base stations throughout both the entire Acute and MHU buildings. The full network supports, the two main graphic stations which control the whole project with the remaining positions filtered for the MHU Building. There is a further stand-alone MHU Building located off-site about six miles down the road, completed as part of the overall project.
In all, 237 kilometres of cable were used across the site, connecting over 25 thousand individual components such as manual control points, sounders, bases, panels, interfaces, beacons, etc. – all Protec 6000 series equipment.
By utilising specially designed and patented interface units, the system controls the hospital’s smoke damper systems. By doing this, it means that via the graphics on the PC, operators can see all areas and the dampers and can control them to prevent any smoke and toxic fumes from spreading, enabling any people in other areas to leave safely. The fire detection and alarm systems offer state-of-the-art intelligent networks that pave the way for the next generation of designs, introducing technology that reduces cost by removing the need for duplication of wiring and power supplies.
The total number of smoke dampers used for the project was 1500 in the acute wing, with a further 135 in the Mental Health Unit (MHU). The associated Protec smoke damper interfaces allow the control of these devices to utilise the fire detection and alarm loop and avoid the need for separate power supplies, distribution boards, and additional circuit protection.
A voice evacuation public address system has also been linked to the fire detection system to make this a truly integrated network and further improve cost-saving efficiency.
Robert Cash, Protec Fire Detection plc Project Manager, said: “As a new build, we have been able to design and install the ideal network systems to make this a future-proof landmark development. Additionally, with the integration of smoke damper control, we have probably shaved around £100K from the overall project cost.”
Since the completion of the project, Protec has continued to supply the hospital with fully comprehensive maintenance and service contract. Due to the size of the project, the hospital benefits from a site-based engineer to service and maintain the system and holds meetings with the FM Provider regularly. Also, Protec has secured multiple other buildings on-site which all integrate to the existing fire alarm network.
