Apollo Is The Royal Partner Of Choice

Apollo Fire Detectors Ltd has been granted the Royal Warrant by Her Majesty The Queen in recognition of its official supplier status to the British Royal Household.

Windsor Castle

Granted to individuals or companies who have supplied goods or services for at least five years to HM The Queen, HRH The Duke of Edinburgh or HRH The Prince of Wales, Royal Warrants are widely regarded as demonstrating excellence and quality, and are highly prized.

As a ‘Warrant Holder’, Apollo Fire Detectors may display the Royal Arms of HM The Queen and the legend ‘By Appointment’ on their products, premises, stationery and advertising.

“Royal Warrant Holders are united by their commitment to the highest standards of service and excellence,” comments Danny Burns, Managing Director of Apollo Fire Detectors. “We are very honoured to receive this prestigious accolade and will continue to uphold the exceptionally high standards the Royal Warrant represents.”

Apollo is no stranger to Royal approvals, having been the first company of its kind to hold three consecutive Queen’s Awards for Export Achievement. It now exports to more than 120 territories and its comprehensive range of products is certified to all key international standards. Apollo holds in excess of 3,000 product approvals worldwide as well as a number of internationally recognised quality and environmental awards.

Apollo’s New DIN-Rail Sounder Controller Has Increased Current Capacity

Unit can drive higher powered sounders or up to five times as many conventional sounders

Apollo Fire Detector’s new DIN-Rail Sounder Controller has an increased current capacity – from 1A to 5A – allowing it to drive more powerful sounders or up to five times as many conventional sounders or visual warning devices. This capacity is particularly useful under the Disability Discrimination Act, which requires sounders with a higher sound output. It is also ideal for use in areas with high background noise such as factories, petrochemical plants and offshore platforms. The device complies with the Construction Product Directive (CPD) (89/106/EC) and meets the EN54-18 standard.


As well as driving a zone of externally-powered sounders and/or visual warning devices, the Sounder Controller reports their status back to Apollo-compatible analogue control equipment. In normal operation it returns a pre-set analogue value of 16, but in the event of an open or short-circuit fault, or a fault in the external power supply, the unit returns a pre-set analogue value of four.

The device allows warning devices to be operated continuously or to be pulsed one second on, one second off, and can be operated individually or in groups. Whichever address mode has been applied, it can be synchronised when in pulsed operation. An opto-coupled input is also provided which monitors the state of the external power supply.

The Sounder Controller also has the facility to monitor the presence and polarity of the external power supply to the sounders. This is achieved through a circuit which includes an input to monitor a volt-free, normally-open contact. A wire link must be fitted if the fault contact is not used. The unit will only operate with control equipment using Apollo’s XP95 or Discovery protocols and its features are only available when the device is connected to a panel with the appropriate software.

The device is supplied in a housing which simply clips onto a standard 35mm DIN rail (DIN 46277). Connections are via plug-in terminal blocks which accept wires up to 2.5mm. Two LEDs (red and yellow) are visible through the top of the enclosure: the red LED pulses or is illuminated to indicate that the sounders are, respectively, pulsed or switched on continuously, while the yellow LED is illuminated when a fault condition has been detected. If the fault LED is not required or the extra loop current to illuminate it is not available, it can be disabled with the eighth segment of the DIL switch.

Loop powered and operating at 17-28V DC, the Sounder Controller requires a local power supply of 12-35V DC to power the external load, up to 5A. A polarising diode is required with each alarm device, as the sounders are operated by voltage reversal, provided by a double-pole change-over relay. The sounder circuit is protected by a quick acting miniature fuse (TR5) rated at 5A.

Apollo Specified For Arup’s £43 Million London Office Development

World class fire detection from Apollo Fire Detectors has been specified for a new £43 million commercial development in London’s West End. Once completed, 8 Fitzroy Street, W1 will become the London base of Ove Arup, the global firm of designers, engineers, planners and business consultants.

Fitzroy Street

The contract to supply the building’s fire system, which is being installed in two phases, was awarded to Titan Fire & Security. Tony Tutton, Business Development Manager, says: “Ove Arup is a very important client for us and the project had very strict requirements.  A fire system based on Apollo’s Discovery range was specified which provided a flexible and fully compatible solution.”

The Discovery range allows for the provision of different levels of sensitivity depending on the needs of the space to be protected. This is possible because Apollo Discovery fire detectors feature five panel-selectable sensitivity bands that make them particularly adaptable to a wide range of environmental conditions. To help to protect against unwanted alarms even further, devices in the Discovery range are also equipped with inbuilt drift compensation. They are LPCB approved to EN54 in every one of these modes.

Phase two is now complete and when phase three is completed in 2009, the fire system at 8 Fitzroy Street will comprise almost 600 Apollo devices, including Discovery smoke, heat and flame detectors, manual call points and interfaces. Warnings are provided using a combination of Apollo sounder bases and sounder beacon bases. The fire system is controlled using two four-loop Morley ZX5e panels.
