SigNET’s powerful Integrity voice alarm/public address system has been installed at a prestigious Crown Court building in the Borough of Hounslow in London as part of a multi-million pound expansion project.

The existing Court building in Isleworth has been extended to accommodate six new Crown Courts, a development which will increase custodial capacity and the infrastructure necessary for the courts to function. The ambitious project called for a complete overhaul of the life-safety equipment and SigNET’s Integrity was approved for the site.

Integrity combines a voice alarm system with a high specification public address system and is incredibly flexible. Consisting of two networked 42U racks, supporting a combination of 331 BS 5839-compliant vandal resistant ceiling speakers across 18 separate PA zones, the system also includes a custom-paging panel in the main reception and a firefighter’s microphone in the main security control room for the day-to-day management of the site.

Fully compliant with BS5839 Part 8, BS7827 and BS-EN60849, Integrity’s unique PC software enables a VA/PA system to be designed and demonstrated prior to purchase. Its capacity for all cause and effect scenarios to be tested and auditioned gives site management unrivalled confidence and control over site evacuation strategies.

Says Philip Ridealgh of Caldera Fire & Security, the BAFE SP203 accredited company that installed the system: “The project involved the installation of a brand new fire alarm system and a combined Integrity voice alarm/public address system, within the existing Isleworth Crown Courts and a newly constructed ground to second floor extension. The installation took place over a 13-month period, leaving the existing manual conventional fire alarm system with bells and separate public address system functional throughout. We chose Integrity due the fact that it is a flexible yet very powerful voice alarm”.

A rotation of courts and facilities allowed the site to function continuously throughout the “new build” and refurbishment programme. Comments Philip: “Two thirds of the installation was carried out in a fully functioning Crown Court and our engineers maintained an excellent working relationship with our client, the builder and Her Majesty’s Court Services, to bring the project to a highly successful conclusion for all parties”.
