Apollo Orbis BS Heat Detector with Flashing LED ORB-HT-11016-APO

Apollo Orbis BS Heat Detector with Flashing LED ORB-HT-11016-APO OperationApollos Orbis heat detectors have an open-web casing which allows air to flow freely across a thermistor which measures the air temperature every 2 seconds. A microprocessor stores the temperatures and compares them with pre-set values to determine whether a fixed upper limitthe alarm levelhas been reached. In the case of rate-of-rise detectors the microprocessor uses algorithms to determine how fast the temperature is increasing. Static heat detectors respond only when a fixed temperature has been reached. Rate-of-rise detectors also have a fixed upper limit but they also measure the rate of increase in temperature. A fire might thus be detected at an earlier stage than with a static detector so that a rate-of-rise detector is to be preferred to a static heat detector unless sharp increases of heat are part of the normal environment in the area protected by the heat detector.Brand FeaturesTimeSaver Base designed for fast installationStartUp for fast commissioningFasTest reduces maintenance timeautomatic drift compensation with DirtAlert warning to easily identify dirty detectorsSensAlert which indicates that the detector is not operating properlywide voltage and operating temperature rangesoptical sensor designed for high reliability and reduced false alarm incidencemultisensory smoke detector for detecting fast-burning firesflashing LED option

Apollo Discovery Marine Optical Smoke Detector 58000-600MAR

Apollo Discovery Marine Optical Smoke Detector 58000-600MARThe Discovery Marine Optical Smoke Detector works using the light scatter principle and is ideal for applications where slow-burning or smouldering fires are likely.Operating PrinciplesThe Discovery Marine Optical Smoke Detector has a white moulded polycarbonate case with wind-resistant smoke inlets.The indicator LEDs are colourless when the detector is in quiescent state and red in alarm. Within the case is a printed circuit board which on one side has the light-proof chamber with integral gauze surrounding the optical measuring system and on the other the signal processing and communications electronics.An infra-red light emitting diode within its collimator is arranged at an obtuse angle to the photo-diode. The photo-diode has an integral daylight-blocking filter.The IR LED emits a burst of collimated light every second.In clear air the photo-diode receives no light directly from the IR LED because of the angular arrangement and the chamber baffles. When smoke enters the chamber it scatters light from the emitter IR LED onto the photo-diode in an amount related to the smoke characteristics and density. The photo-diode signal is processed to provide an analogue value for transmission when the detector is interrogated.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.

Apollo Discovery CO Heat Multisensor 58000-305APO

Apollo Discovery CO Heat Multisensor 58000-305APOThe Discovery COHeat Multisensor Detector is good at detecting deep-seated smouldering fires which give off a lot of CO as well as flaming fires. They are ideal for use in hotel bedrooms where steam may bepresent dusty environments or even where simulated smoke may bepresent.The Discovery COHeat Multisensor Detector contains a CO detection cell and a thermistor temperature sensor whose outputs are combined to give the final analogue value. The way in which the signals from the two sensors are combined depends on the response mode selected. The COHeat Multisensor detects the presence of carbon monoxide or heat or a combination of both. The Multisensor construction is similar to that of a CO detector but uses a different lid in order to expose the thermistor to the surrounding air. The signals from the CO sensing cell and the thermistor are independent and represent the amount of CO or the temperature present in the vicinity of the detector. When the detector is used in heat only mode Mode 5 it operates as an A1R rate-of-rise heat detector with a static threshold of 58C.Brand 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.Operating PrinciplesDiscovery detectors are designed to be operated with purpose-designed control and indicating equipment that makes full use of their features.

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
