Apollo Discovery Marine Heat Detector 58000-400MAR

Apollo Discovery Marine Heat Detector 58000-400MAR

Apollo Discovery Marine Heat Detector 58000-400MARDiscovery Marine analogue addressable fire detectors are suitable for larger vessels. The high specification range has been developed to meet the requirements of sophisticated systems. Discovery gives you total reassurance in installations where it is necessary to adapt detection to different operating environments and where protection against unwanted alarms is paramount.The Discovery Marine Heat Detector uses a single thermistor to sense the air temperature at the detector position. The thermistor is connected in a resistor network which produces a voltage output dependent on temperature. The design of the resistor network together with the processing algorithm in the microcontroller gives an approximately linear characteristic from 10C to 80C. This lineariser signal is further processed depending on the response mode selected and converted to an analogue output.Key FeaturesApproved for use in the marine environmentFive response modes for environmental adaptationDaynight switching for increased flexibilityDrift compensation for false alarm reductionUser programmability for dataXPERT card addressing for increased securityIdeal in environments that are dirty or smokyUnaffected by wind or atmospheric pressureRemote test feature

Apollo XP95 Multisensor Detector 55000-885APO

Apollo XP95 Multisensor Detector 55000-885APO

Apollo XP95 Multisensor Detector 55000-885APOThe XP95 multisensor Detector contains an optical smoke sensor and a thermistor temperature sensor whose outputs are combined to give the final analogue value.The multisensor construction is similar to that of the optical detector but uses a different lid and optical mouldings to accommodate the thermistor temperature sensor. The sectional view shows the arrangement of the optical chamber and thermistor.The signals from the optical smoke sensing element and the temperature sensor are independent and represent the smoke level and the air temperature respectively in the vicinity of the detector.The detectors microcontroller processes the two signals.The temperature signal processing extracts only rate of rise information for combination with the optical signal. The detector will not respond to a slow temperature increase - even if the temperature reaches a high level. A large sudden change in temperature can however cause an alarm without the presence of smoke if sustained for 20 seconds.The processing algorithms in the multisensor incorporate drift compensation. The control panel must not have a drift compensation algorithm enabled. The sensitivity of the detector is considered the optimum for most general applications since it offers good response to both smouldering and flaming fires.Key FeaturesSensitive to a wide range of firesWell suited for environments such as hotel bedroomsUnaffected by wind or atmospheric pressureOther part codes include AD-2004

Apollo Discovery Heat Detector 58000-400APO

Apollo Discovery Heat Detector 58000-400APO

Apollo Discovery Heat Detector 58000-400APOThe Discovery Heat Detector uses a single thermistor to sense the air temperature around the detector.Discovery heat detectors have a common profile with ionisation and optical smoke detectors but have a low air flow resistance case made of self-extinguishing white polycarbonate. For the European standard version of the detector the five modes correspond to five classes as defined in EN 54-5. The classes in this standard correspond with different response behaviour each of which is designed to be suitable for a range of application temperatures. All modes incorporate fixed temperature response which is defined in the standard by the static response temperature.Application EnvironmentsCarpark Loading BaysDusty EnvironmentsHospitalsHotelsMedium to Large BuildingsOfficesUniversity CampusesWarehousesBrand InformationDiscovery is a range of high-specification analogue addressable fire detectors and alarm devices. Discovery detectors offer effective false alarm management by a combination of EN 54 approved operating modes and sophisticated algorithms.Drift compensation further reduces the likelihood of false alarms caused by a build-up of dust in the sensing chamber.In addition to the familiar smoke and heat detectors the Discovery range features two multisensor detectors. One is an opticalheat multisensor which can be used to protect against many types of fire risk. The other is a carbon monoxideheat multisensor which protects against both smouldering fires and those generating heat.Electrical ConsiderationsThe Discovery Heat Detector uses a single thermistor to sense the air temperature at the detector position. The thermistor is connected in a resistor network which produces a voltage output dependent on temperature. The design of the resistor network together with the processing algorithm in the microcontroller gives an approximately linear characteristic from 10C to 80C. This linearised signal is further processed depending on the response mode selected and converted to an analogue output.Operating PrinciplesDiscovery detectors are designed to be operated with purpose-designed control and indicating equipment that makes full use of their features. Discovery can however be connected to any fire control panel which can operate existing ranges of Apollo analogue addressable detectors with the previously noted rule that the control and indicating equipment must not have a drift algorithm operating on Discovery devices. Contact the fire control panel manufacturer for guidance.CommunicationDiscovery uses a digital communications protocol which has been developed from the XP95 protocol but differs in that it allows communication in three different modes Normal Read and Write to allow a more extensive exchange of information and commands than previous analogue addressable ranges. In addition discovery can store data in non-volatile memory.- The Normal mode is identical to the XP95 protocol with the exception that the five additional analogue value bits in the XP95 protocol extension have been re-defined so that the fire control panel is able to distinguish between Discovery and XP95 devices.- The Read mode is used to check information stored in the non-volatile memory of each detector. It is accessed by using a simple extension to the Normal mode communication method from the fire control panel to the detector.- In Write mode the fire control panel is able to write information to the detector by extending the communication method in the same way as in Read mode. During Read or Write modes a detector can signal an alarm by means of the alarm flag and alarm address bits.Discovery detectors are compatible with XP95 and Soteria. It should be noted however that Discovery features will not be available when Discovery is used with XP95 fire control panels. Fire control panels with drift compensation algorithms should disable the algorithms when communicating with Discovery.For fire control panels running CoreProtocol please refer to the fire control panel manufacturers operating instructions.Maintenance ServiceDetectors should be maintained according to BS 5839-1 or other locally applicable code. Test Equipment can be ordered from us which can test smoke and heat detectors.Detectors should not be cleaned in the field except for careful removal of exterior dirt with a damp cloth.EMC Directive 2004108ECThe Discovery Heat Detector complies with the essential requirements of the EMC Directive 201430EU provided that it is used as described in this datasheet.A copy of the Declaration of Conformity is available upon request.Key Features Ideal in environments that are dirty or smoky under normal conditionsWell suited for warehouses loading bays and car parksUnaffected by wind or atmospheric pressureFive response modesRemote test feature
