Combined Sounder, Beacon And Isolator In One Unit

Apollo’s new Sounder Beacon Base combines an integrated base sounder, loop-powered beacon and isolator in one unit. A smoke or heat detector would normally be fitted to the base, but red and white caps can be used instead to enable operation as a stand-alone sounder/beacon. A version of the base without an isolator is also available.

The device enables building owners to meet the requirements of the Disabilities Discrimination Act (DDA,) which requires visual alarms for the hard of hearing, and also the revised Approved Document M of the Building Regulations for England & Wales, which stipulates provision of visual, audible and detection devices in every bedroom and visual and audible devices in every bathroom. Major applications include hotels, accommodation blocks and leisure facilities.

The Sounder Beacon Base has two volume ranges: 55-75dB and 75-91dB, which can be synchronised when multiple devices are used. It also has a unique acoustic self-test facility that can be used during installation, commissioning or maintenance procedures. It tests itself by checking its own sound output; if no sound is detected within five seconds of switching on, it transmits a sounder fault signal when next polled.

The device is compatible with Apollo’s XP95 and Discovery ranges of intelligent fire detectors, as well as other Apollo alarm devices and interfaces.

Apollo Fire Detectors Protect Styal Mill

Apollo Discovery and XP95 fire detectors have been installed to protect Styal Mill, a working museum and industrial heritage site near Wilmslow, Cheshire, which is owned by the National Trust. The intelligent fire detection system incorporates over 700 Apollo devices and forms part of an upgrade of the whole property. The fire detection system was supplied by First City Fire & Security and installed by G R Bayley Electrical to meet the client’s specification.

Styal Mill, which is also known as Quarry Bank Mill, is a museum which charts the history of silk and cotton making. Set in the beautiful Styal Country Estate, the Georgian building dates from 1784 and now serves as a resource for learning about the industrial and social heritage of textiles manufacturing. Among other attractions, visitors to the site can see working demonstrations of textile production, the most powerful working waterwheel in Europe, and one of the earliest steam-powered beam engines to be built in the world. The museum also houses a restaurant and café and is hired out as a conference centre and wedding venue.

The design of the fire detection system had to take into account the diverse activities that take place in the museum. Barry Cook, Manager at Styal Mill and a chief engineer for The National Trust, explains: “We had to ensure that the fire detection system protected out visitors as well as the mill equipment, which is irreplaceable. We also wanted the best specification possible at the best price.”

Having examined the client’s requirements, First City Fire & Security and G R Bayley recommended a fire detection system based on Apollo technology. Managing Director of First City Fire & Security, Darren Morrell, comments: “We know Apollo well and consider them an excellent company with which to work. As well as offering a wide range of options and add-ons, they are very competitive on price. We try to give our installers a good deal and this was definitely the best option for them, too.”

Jason Dunn, contracts manager of G R Bayley adds: “The open digital protocol shared by all Apollo intelligent fire detection products enables forwards and backwards compatibility, so we have confidence that future maintenance and system upgrades will be easily achievable.”

The new fire detection system at Styal Mill is based around two Morley networked analogue addressable control panels. The working demonstration areas, where activities such as spinning can create a lot of dust that could lead to unacceptably high incidences of nuisance alarms, are protected with approximately 300 Apollo Discovery multisensor fire detectors. .

The Discovery multisensor uses an optical smoke and a thermistor temperature sensor in combination, which means it responds well to a range of fires. The outputs from both sensors are analysed to produce the final analogue value, which makes the multisensor particularly reliable and virtually eliminates causes of false alarms such as steam, exhaust fumes and transient high dust levels, like those encountered at Styal Mill.
In addition to the Discovery multisensors, the Styal Mill fire detection system includes some 400 other devices from the compatible XP95 analogue addressable range including optical smoke and heat detectors, manual callpoints, loop-powered sounders and loop-powered sounder beacons. It also interfaces with other pieces of plant such as boilers, gas valves and lifts. The fire detection system uses a ‘one out, all out’ evacuation principle in the event of an emergency.

Commenting on the new fire detection system, Styal Mill Manager Barry Cook says: “The Apollo system is highly efficient, the panels are user-friendly and the installers provided exactly what we wanted. We suffered a number of false alarms with the old system, which proved very costly. Since the Apollo fire detection system was installed, these have been completely eradicated.”

Apollo Intelligent Fire Detection System Protects Robin House Children’s Hospice In Scotland

An intelligent fire detection system incorporating over 400 Apollo devices has been installed to protect a children’s hospice near Loch Lomond. Robin House is one of only two children’s hospices set up by the Children’s Hospice Association, Scotland (CHAS). The fire detection system was supplied and commissioned by Glasgow-based Advanced Fire & Security, which will also maintain the system.

Robin House is a modern, architecturally innovative building set in the heart of the National Park. The hospice offers specialist palliative support through respite care and emergency care for children with life limiting, life threatening and terminal conditions, and provides regular short term breaks for up to eight children and their families at a time.
The eight family bedrooms plus the eight children’s bedrooms can cater for up to thirty-five people and are located on the lower floor and ground floor, where each has its own exit. Straightforward evacuation procedures were key to the building design in order to accommodate the varying degrees of mobility of the children staying at the hospice. In addition, there is lift access to the first floor, a hydro-therapy pool and several communal areas featuring walls and ceilings made entirely of glass so that the beautiful surroundings can be enjoyed to best advantage.

The fire system specification stipulated an open protocol system for which replacement products would be readily available. Advanced Fire & Security recommended Apollo technology. Peter Keenan, Director of the company, explained: “Apollo was the perfect choice for this system because the technology is well proven and it is also backwards and forwards compatible. The system can accommodate changes of use so that if an extension of the system or replacement detectors were ever required, this would be a simple procedure.”

Advanced Fire & Security supplied an intelligent fire detection system based around a four-loop control panel. The system incorporates 100 smoke detectors and 42 multi-sensor detectors from Apollo’s XP95 range, plus eight sets of beam detectors for some of the larger, communal areas.

The fire detection system is designed to provide ‘one out, all out’ evacuation in the event of an alarm, but there is provision for an abnormal reading to be investigated to avoid unnecessary disruption to the children and their families. Staff are alerted to an incident first and can cancel the alarm within two minutes if no action is required.  If the alarm is not cancelled within two minutes, sounder beacon units are triggered to signify full evacuation. One member of staff is allocated to each family to ensure that all parties exit safely.

The fire detection system also interfaces with other equipment, including a VESDA aspirating smoke detection system, all internal corridor doors and the lifts in the building, which will return to the ground floor in the event of a fire.
