Apollo specified to protect Boots the Chemist premier Oxford Street Store
An Apollo-based intelligent fire detection system has
been specified to protect the new Boots the Chemist premier store
in Oxford Street, London, UK. The system was designed by
Charterhouse Building Services and is being installed by Erif (UK)
Limited. Erif already has an ongoing maintenance agreement with the
client, but won the contract to install the Oxford Street fire
detection system under competitive tender.
The fire system specification for all Boots the Chemist premises
stipulates an open protocol - a requirement that has been fulfilled
by using Apollo fire detection products. The protocol that Apollo
detectors use has been available since 1986, when the company
introduced its first range of intelligent fire detectors. Since
then it has been extended - once for the XP95 range and once for
the Discovery range -
but never modified. This ensures forwards and backwards
compatibility between products, simplifying the extension of
systems and making replacement of component products during changes
of use or upgrades easier.
The fire detection system at Boots the Chemists, Oxford Street,
is designed to L1 requirements. It comprises two Kentec Syncro
four-loop control panels and over 500 Apollo Discovery intelligent
fire detectors and devices.
Discovery Range
The Discovery range has been specifically developed to meet two
key market demands: adaptability to changing conditions and
protection against unwanted alarms. Evolved from the proven
technology behind Apollo's acclaimed XP95 range, Discovery gives
specifiers and users five panel-selectable bands, inbuilt drift
compensation, a non-volatile memory and fail-safe operation.
The range comprises ionisation and optical smoke detectors, a
temperature detector, a multisensor (combined smoke and
temperature) detector and a manual call-point. There is also the
Discovery Carbon Monoxide (CO) fire detector, which offers fast and
accurate sensing technology and requires only very low power.
Each detector in the Discovery range can operate in one of five
response modes, any of which can be selected from the control
panel. Each mode corresponds to a unique response behaviour, which
can be broadly related to sensitivity to fire. Whatever the type of
detector, mode 1 will give higher sensitivity to fire than mode 5.
Therefore, Discovery detectors set to mode 1 will be most suitable
for environments in which sources of unwanted alarms are rare, for
example cleanrooms and computer suites. At the other extreme,
response mode 5 will be suited to more dusty or smoky environments
such as loading areas where diesel forklift trucks are operating.
Response mode 3 is a general-purpose setting.
