Case study

Royal Brompton Hospital

The Trust is the largest cardiothoracic centre in the UK and consists of two hospitals: Royal Brompton Hospital, London and Harefield Hospital, Middlesex.

The Challenge

The Trust adopted P4 as their supplier for emergency lighting in 2008. John Calvert, the Trust’s in house Fire Officer recognised the importance of guaranteed testing of all the emergency lighting throughout the Trust’s buildings for compliance with BS5266 and the Regulatory Reform Order. The chosen system would need to be modular, so that it could be gradually added to, in phases, to suit budget constraints and risk assessments. Upgrading the emergency lighting in their hospitals would be a long term project, and the Trust wanted to reap the cost saving benefit of self-test, in each phase.

What we did

  • Commissioned a remotely monitored P4 Fastel Link M-web+ system, monitoring over 600 emergency lights, across the Harefield Hospital estate.
  • Worked with the Trust to implement a P4 wireless system, operating 160 self-testing luminaires, consisting of P4’s own LED Quatrum range, together with some converted other manufacturer’s mains luminaires, in the Chelsea Wing, Royal Brompton Hospital.
  • Support for the Trust’s pre and post solution implementation need to continue to provide a safe and disruption free environment for all of their staff and patients.


  • Remote monitoring of both Trust hospital locations’ emergency lighting installations, from either site.
  • The modular nature of P4’s systems, enabling a single M- web+ ‘head end’, with associated Collector Boxes sited in each building, mean Harefield are able to phase the roll out of the system, taking best advantage of their buildings’ underground service duct network.
  • The Trust calculated that implementing a P4 wireless system solution for the Chelsea Wing, would reduce testing and on-going maintenance costs such that it would pay for itself within 3 years.
  • Minimal patient disruption – the addressable Fastel solutions allow the Trust to set times when it is convenient to automatically and individually test the emergency lights connected to the system, thereby minimising disturbance during times when patients are sleeping or receiving treatment.
