Hochiki Europe has installed its fire detection products, including its Enhanced Systems Protocol (ESP), in London’s Savoy Theatre
he Savoy Theatre is an iconic venue in London’s West End which first opened its doors to the public in 1881 and has been host-
ing a variety of performances from operas to pop concerts ever since. It also holds the accolade of being the

first public building in the world to be lit entirely by electricity. Sir Joseph Swan, inventor of the incandescent light bulb, supplied around 1,200 of his Swan lamps to the theatre, which were powered by a generator. The theatre is also no stranger to the
dangers of fire having been severely damaged in 1990 when a blaze gutted most of the building. Since then, the prevention of fire within the Savoy Theatre has been a top priority.
director, explained, “In 2002, following the introduction of the Fire Precautions (Workplace) Regulations, we were invited to sit down with theatre owners, the London Fire Brigade and representa- tives from Westminster Council. The purpose of which was to develop a generic strategy to clarify the relation- ship between the operation of the fire detection and alarm system and the evacuation policy to be employed by theatre management and staff. Our spec- ification was accepted and is still worked to today in many of London’s West End Theatres.” Following the guidelines, CTA Fire
recommended the installation of a BS5839 part 1:2002 compliant Category L2/P2 addressable fire detection system in the Savoy. An L2 system is designed

Wireless fire detection
A
pollo has updated and extended its XPander range of wireless fire detectors. Designed for use
in areas where hard-wired fire detection is impossible or impractical, XPander devices are ideal for use in historic buildings, remote annexes and temporary structures. Large amounts of cabling for hard-wired fire
detection can be impractical where there is a need to protect a building’s interior or where there are many buildings spread across a site. Temporary structures also require adequate fire protection, yet installing hard-wired technology
in these
circumstances can be expensive or impractical. The extended XPander range includes two new
products and now consists of an optical smoke detector, a multisensor smoke detector, heat detector types A1R and CS, a wireless base, a manual call point, a sounder and a sounder beacon, and Single and Dual Input/Output Units. The complete range has been granted the new wireless link fire standard EN54 Part 25, which is the standard for European-compliant radio products.

directional quad element PIR and K-band microwave sensing. This gives the detector maximum catch performance and false alarm immunity, even in challenging environments such as partitioned areas, commercial premises and residential housing. The Prestige 360 DT has a maximum 9.3m diameter
Ceiling Mount Intruder Detector T
he new Prestige 360 DT from Texecom is a ceiling mount intruder detector that features both omni-
detection pattern, which results in over 65m2 of omni- directional coverage under each detector. The product is suitable for mounting up to 3.6m above the ground, and complies with EN50131-2-4 Grade 2 requirements. Ceiling mount detectors are of particular benefit when
protecting areas with ground-based obstructions such as cubicle partitions, shopping aisles and large furniture.

also had to be P2 property protection compliant to provide detection in parts of the Savoy where the risk of ignition is high and/or the contents are particularly valuable. P2 systems state that there must be fire detection in specified parts of the building to pro- vide early warning of fire in areas of high fire hazard level, or areas in

he Didcot Railway Centre, a unique collection of Great Western Railway steam engines, coaches, wagons, engine sheds and memorabilia; and a
recreation of Brunel’s famous broad gauge railway, has installed Kentec fire control panels at the heart of a new fire safety system, designed and installed by Kingwood Safety Systems. As well as its Science, Learning & Railways training areas housed in two railway coaches, the centre has five carriages specifically for accommodating centre workers, each requiring round-the-clock automatic fire detection as a distinctly independent zone. To allow for any of the carriages to be safely decoupled and relocated, a linked conventional twin wire fire alarm system has been installed with a Kentec 4 zone twin wire Sigma CP conventional fire alarm control panel in the 10 berth main carriage that connects to the other four carriages via separate zone connections. The system includes conventional smoke and heat detectors from the Hochiki CDX range as well as a series of specialist IP68 weatherproof connectors positioned on the outside of the carriages.
