Brand Information

XP95 Intrinsically Safe (IS) detectors are a development of the well established analogue addressable XP95 range from Apollo. XP95 IS detectors feature all the benefits of the standard range, but are developed specifically for use in hazardous areas. The addresses of XP95 IS detectors are set by means of the patented XPERT card.

Operation

The sensing part of the detector consists of two chambers – an open, outer chamber and a reference chamber within. Mounted in the reference chamber is a low-activity radioactive foil of Americium 241 which enables current to flow across the inner and outer chambers when the detector is powered up. As smoke enters the detector, it causes a reduction of the current flow in the outer chamber and hence an increase in the voltage measured at the junction between the two chambers. This analogue voltage signal is converted to a digital signal by the electronic circuitry and transmitted to the control panel on interrogation. The micro-processor in the control equipment then compares the signal with stored data and initiates a pre-alarm or fire alarm as smoke density increases. When a fire condition exists, the panel instructs the detector to switch on its indicator LED.

Safety Note

Safety note In the United Kingdom, ionisation smoke detectors are subject to the requirements of the Radioactive Substances Act 1993 and to the Ionising Radiations Regulations 1999 made under the provisions of the Health and Safety at Work Act 1974. The detectors, independently tested by the National Radiological Protection Board (NRPB), conform to all the requirements specified in the ‘Recommendations for ionisation smoke detectors in implementation of radiation standards’ published by the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD) 1977. There is no limit to the number of ionisation smoke detectors which may be installed in any fire protection system. Storage regulations depend on local standards and legislation, but, in the UK, up to 500 detectors may be stored in any premises, although there are stipulations on storage facilities if more than 100 ionisation detectors are stored in one building. At the end of their recommended working life of ten years, ionisation smoke detectors should be returned to Apollo for safe disposal or disposed of in an otherwise locally approved and environmentally safe manner. Please see “A guide to the care, maintenance and servicing of Apollo products”, PP2055. Guidance on storage and handling can be given by Apollo Fire Detectors and full details can be requested from: Environmental Agency Swift House Frimley Business Park Frimley GU16 7SQ Outside the UK, please contact the relevant national agency.
