WES+ temporary alarm system is protecting the original Scotland Yard police station in London whilst it is turned into a five-star luxury hotel by Galliard Homes.

Client: Gaillard Homes | Project Value: £110 million | Project Type: Redevelopment | Location: London

The historic building served as the headquarters for the Metropolitan police from 1829 to 1890 and the
development involves retaining the original Edwardian façade.

Galliard Homes makes fire safety a priority on all its developments, which is why the project team at Great Scotland Yard set about identifying what they considered to be the ‘most effective fire alarm system’ currently available.

The company had used a hard-wired fire alarm system on other construction sites but found it to be
cumbersome. The trailing wires created a trip hazard and the process of repositioning the call points as work progressed was both time consuming and required a qualified electrician.

David Ridge, Sites Services Manager at Galliard Homes, said: “We felt that there must be a better way of protecting the Great Scotland Yard development from the dangers of fire. Following extensive research, we identified WES+ as a system that would provide us with a step-change in usability by the fact it is wireless.”

He added: “That overcame the challenges we had with hard-wired systems and being compliant with the relevant sections of EN 54 meant that we were also confident that it gave us the best fire protection. When we complete Great Scotland Yard later this year, we will be able to transfer the WES+ system to our next project, making it is the best and most cost-effective system on the market today without a doubt.”

The WES+ system installed at Great Scotland Yard will trigger a site-wide alarm even if just one of the manual call points or automatic heat/smoke detectors are activated. This will allow all personnel to evacuate the site and rescue services to be alerted at the earliest opportunity.

Incorporating heat/smoke detectors into the WES+ fire alarm system means that the iconic Great Scotland Yard is protected 24/7, even when personnel are not present on site. Nominated personnel at Galliard Homes will instantly receive a text alert if any call point is activated.

The WES+ fire alarm system, which can be installed with a few simple button-presses to pair the interconnecting call points, creates a completely secure mesh network. The scalable nature of the system means that up to several thousand units can be paired, making it suitable for large and small construction sites. A silent test facility eliminates downtime on site.

Additional complexity was added to this project because it is in the heart of one of London’s most popular tourist areas and surrounded by other significant buildings that house large numbers of people. A fire during construction could soon spread to adjoining buildings. As the dangers of fires on construction sites become better understood an increasing number of developers are specifying a WES+ fire alarm system.

Insurance companies and clients are also encouraging developers to use an EN 54 compliant fire alarm system that incorporates automatic heat/smoke detectors. Zurich Insurance has stated that there is an ‘expectation that customers comply with the Joint Code of Practice Fire Code guidelines as far as is practicable and reasonable’.

The Joint Code of Practice on the Protection from Fire of Construction Sites and Buildings Undergoing Renovation (JCOP) now contains the advice; Components of automatic fire detection and alarm systems should be marked as complying with EN 54 (paragraph 13.8).

Along with Galliard Homes, WES+ is currently used by over 75 percent of the top 100 UK constructions companies to protect personnel and assets from fire on site. It is designed specifically for construction sites and has a three-year battery life.

  • Heat, smoke and dust resistant detector heads available
All units both send and receive radio signals, for maximum robustness of network coverage. Since detection units are incorporated into your WES network, they will they act as an early warning of fire risk to all site staff during the working day and they’ll also make sure that the site remains protected out of hours.
If you add a GSM base station, you can even make sure that security and monitoring personnel receive a text alert if the fire alarm is automatically triggered.
WES3 Interface
The WES fire alarm Interface lets you connect your WES temporary fire alarm to other systems, such as turnstiles, so that you can ensure your emergency systems are working together as efficiently as possible to protect your site.
  • Input: Connect so that the WES fire alarm system can be triggered to sound the alarm by an external system
  • Output: Connect so that the WES system going into alarm triggers an action on the part of an external system, eg auto dialler or access control
Note that the Interface cannot be connected directly to the mains current, and you will need a suitably qualified person to wire together the units.
WES3 Link Unit
The Radio Repeater Link unit is the simple, cost-effective way to extend the range of your WES temporary fire alarm system on very large-scale sites.
Simply connect to your existing WES units, set up on site and the unit will act as a relay to link geographically separated sections of the site together.
