Apollo specified to protect Boots the Chemist
An Apollo-based intelligent fire detection system has been specified to protect the Boots the Chemists premier flagship store in Oxford Street, London.
The property is managed by The Mainstay Group.
The specification stipulated an open protocol system for which replacement products would be readily available.
Leader Systems recommended Apollo technology, as Systems Manager Tony Weaver explained: "Apollo's open, digital protocol was an ideal solution to the requirements of this site".

Apollo Discovery multisensors lie at the heart of an intelligent fire detection system installed to protect Belfasts Ulster Hall.
"The technology is well-proven and products based on it are forwards and backwards compatible".
"This simplifies extension of systems or replacement of detectors to accommodate changes of use".
"It also makes future upgrades logistically easier because work can be carried out in phases over time." The Junxion is a nine storey building designed around a central courtyard.
The first seven floors are continuous, with the eighth and ninth occurring only at the corners of the building, creating four "turrets".
There are 99 apartments in all arranged into six core areas, each with its own stairwell and lift access.
The development also includes four retail units on the ground floor.
Due to its town centre location, the developers were aware that the site would prove popular as self-catering accommodation for students from the local University.
The site therefore includes communal facilities such as a laundry and a common room.
Leader Systems provided a tailored solution incorporating detection and software technology that would minimise the number of unwanted alarms".
""The technology in Apollo's Discovery range of intelligent fire detectors is particularly good for reducing unwanted alarms," Tony Weaver says".
""It enables the selection of various sensitivity modes, so the device characteristics - including the appropriate response - can be set according to risk and environment whilst still remaining compliant with standards." Leader supplied an intelligent fire detection system based around a ten-loop Multi Alarm IFAX control panel.
The panel was specially built to meet the required capacity for each fire zone, with 144 zones being displayed on a special repeater panel.
The system incorporates 950 Apollo Discovery smoke and temperature detectors, almost 800 XP95 loop-powered sounders and in excess of 250 interfaces.
Four Apollo Input/Output Units are provided so that separate fire systems in the retail units can be linked in.
There are 569 bedrooms throughout the building, each with its own smoke detector and sounder.
Smoke detectors are also installed in the communal stairways and corridors, with temperature detectors fitted in the open plan kitchen/living areas.
The fire detection system is designed to provide phased evacuation in the event of an alarm.
An alert is raised immediately within the apartment where an incident is detected.
After a period of three minutes, if the alert has not been cancelled, the alarm is raised within that core.
Sounders in adjacent cores are then triggered at further two minute intervals in a 'mushroom' effect until the whole building has been evacuated, or the management team identify the cause of activation and take manual control of the system.
Paul Whittingham of managing agents The Mainstay Group has been responsible for operational matters at The Junxion since it was first occupied".
"With a fire detection system of this size and complexity, combined with the demands of student occupants, we expected some faults to arise".
"However, the incident rate in the first year has been insignificant - well under one per cent".
"The technology is proving extremely reliable.".
