Sector: Building Materials Manufacturing

Sites: 1 Site, Shefford

System: Fire and Access Control


An international building materials manufacturer in Shefford called for the installation of a comprehensive fire alarm system within their office and newly constructed warehouse. They also required a user-friendly entry system at the pedestrian gate, with provisions for future expansion to include vehicle barriers.

Our mission at A-Plus Security was to provide a resilient system that required minimal maintenance and could reliably operate within a mixed-use commercial environment.


The first challenge we faced was that the beam detectors within the warehouse space might clash with the high-level storage racking. Due to the size of the premises and the height of the ceilings, smoke detectors were also not a valid option. Moreover, given the complex building environment with live industrial premises adjacent to and surrounding marshlands, it was important for us to adhere to stringent health and safety policies.

Despite the presented challenges, we remained committed to meeting project timelines and ensuring the client's satisfaction with the completed work.


A-Plus Security installed a comprehensive fire alarm system, which included CAST devices within the office and low-level warehouse areas. For the high-level warehouse spaces, a new FASST ASD system was implemented to cover the extensive 200m x 80m area. This system comprised four FASST 2 pipe ASD panels equipped with bypass and blow valves to facilitate dust clearance by the maintenance contractor.

To ensure the system's efficiency, low-level testing points were strategically placed at the end of each pipe, enabling annual testing and transit time measurements. We also installed a BPT audio intercom system with a keypad function at the pedestrian gate to allow for easy and efficient entry. This system has the flexibility to accommodate future expansion, including the integration of vehicle barriers.

Advantages of This Approach

  • This approach not only provided our client with a reliable system but also offered seamless integration with their site-wide system through interfaces.
  • One of the most significant advantages for our client is the simplified maintenance process. Eliminating the need to access high ceilings for smoke detection system checks has made their maintenance tasks far more manageable.
  • Additionally, this approach plays a crucial role in reducing the occurrence of false alarms, a common issue in environments with dust and continuous forklift activity.

Installed systems

  • Installation of a new CTEC XFP fire panel with CAST devices.
  • 4 x Xtrallis FASST ASD panels with 500+ meters of pipe.
  • · Installation of BPT audio intercom system with keypad to pedestrian gate.

What our
clients have to
say about us

A Plus provides an excellent return on investment, not just through the solution installed, but the general experience they offer from pre-install to post-install and right through to the maintenance of the system. We knew we had made the right decision with A Plus as they offered a comprehensive and detailed proposal and project plan. The skill level of their engineers was a pleasant surprise with their knowledge of IT and networks, as well as electronic security, which made dealing with our internal IT team very smooth. Apart from that, the fact we never had to chase them for anything was a very nice surprise!

International Group of Schools

We chose A-Plus Security to carry out the upgrade of our electronic security systems for our 9 colleges and they have far exceeded our expectations in their approach to the projects. We are a UK wide organisation where the planning and mobilising of these major project around term times is time critical and A Plus Security have been nothing short of fantastic in the communication, there design proposals, openness to last minute changes, pre and post-sales support and their management of 3rd party companies and IT services. We would highly recommend A Plus Security to any organisation who are looking to install or upgrade their systems.

Nationwide Groups of Colleges

A Plus Security exceeded all expectations, following a late award of the contract due to a different contractor pulling out. All fire and security works were completed when requested and signed off on finish, with no issues noted. We have continued working with A Plus on following projects and would fully recommend them.
