Apollo Orbis Intrinsically Safe Optical Smoke Detector with Flashing LED ORB-OP-52028-APO

Apollo Orbis Intrinsically Safe Optical Smoke Detector with Flashing LED ORB-OP-52028-APOThe Orbis IS Optical Smoke Detector works using the light scatter principle and is ideal for applications where slow-burning or smouldering fires are likely.OperationThe Orbis I.S Optical Smoke Detector operates on the well-established light scatter principle. The remarkable optical design of the Orbis I.S. optical smoke detector allows it to respond to a wide spectrum of fires. The sensing chamber of the Orbis I.S. Optical Smoke Detector contains an optical sensor which measures back-scattered light. Sensitivity to black smoke is greatly improved.The detector is calibrated so that it is highly reliable in detecting fires but is much less likely to generate false alarms than ionisation smoke detectors. The stability of the detector - high reliability low false alarm rate - is further increased by the use of algorithms to decide when the detector should change to the alarm state.This removes likelihood of a detector producing an alarm as a result of smoke from smoking materials or from another non-fire source. The sensing chamber has been designed to keep out dust and other airborne contaminants.Key FeaturesReduces false alarmsRecommended for early warning of fire in most areasImproved sensitivity to black smokeCompensation for slow changes in sensitivityAlgorithms for reliability of alarm

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. Detectors should not be cleaned in the field except for careful removal of exterior dirt with a damp cloth.Key FeaturesResponds well to slow-burning smouldering firesSuitable for bedrooms and escape routesUnaffected by wind or atmospheric pressureRemote test featureRejection of transient signals

Apollo White Multi-Tone Open-Area Sounder - 55000-279APO

Apollo White Multi-Tone Open-Area Sounder - 55000-279APOThe Multi-Tone Open-Area Sounder is designed for use in open areas and can be connected to any Discovery or XP95 system. The Multi-tone Open-Area Alarm Devices are powered directly from the loop and need no external power supply. They operate at 18 28V DC and are polarity sensitive.Synchronisation of the tones ensures the integrity of the signal tones from different sounders do not merge into one signal that could be mistaken for a different tone. A nominal sound output of 100dBA is achieved at a current consumption of 5mA in the case of the sounder and 9mA for the sounder beacon.Many control panels will be able to drive up to 20 sounders per loop on average. The maximum number of sounders that may be connected to a particular loop should however be determined by a loop loading calculation using the Apollo Loop Calculator.Key FeaturesUpdated to include choice of tones Apollo slow whoop and DINTwo volume settings 92dBA and 100dBASynchronisation of tonesIndividual and group addressingLoop PoweredRed or White optionsIP21C rated

Apollo Discovery Marine Multisensor Detector 58000-700MAR

Apollo Discovery Marine Multisensor Detector 58000-700MARThe Discovery Multisensor Detector construction is similar to that of the optical detector but uses a different lid and optical mouldings to accommodate the thermistor heat sensor. The sectional view shows the arrangement of the optical chamber and the thermistor. The Discovery opticalheat multisensor detector contains an optical smoke sensor 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 five modes provide response behaviour which incorporates pure heat detection pure smoke detection and a combination of both. The multisensor is therefore useful over the widest range of applications. 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 micro-controller processes the two signals according to the mode selected.When the detector is operating as a multisensor the temperature signal processing extracts only rate-of-rise information for combination with the optical signal. In these modes 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.Key FeaturesIdeal for a wide range of applicationsHigh immunity to false alarmsUnaffected by wind or atmospheric pressureRemote test featureRejection of transient signals

Apollo Discovery Cat O. Discovery Sounder VAD Base with Isolator 45681-700APO

Apollo Discovery Cat O. Discovery Sounder VAD Base with Isolator 45681-700APOThe Discovery Sounder VAD Base makes full use of the Discovery protocol. For ease of commissioning a Magnetic Wand can be used to test and adjust each sounder VAD locally.Key FeaturesEN54-23 certifiedFlash rate of 0.5HzIt is possible to set individual volume of the sounder from the panel15 pairs of tones including IMO code 1A General Emergency Alarm and IMO Code 2 All ClearBuilt in isolatorBrand 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.OperationThe Discovery Multisensor construction is similar to that of the optical detector but uses a different lid and optical mouldings to accommodate the thermistor heat sensor.

Apollo Discovery Multisensor Detector 58000-700APO

Apollo Discovery Multisensor Detector 58000-700APOThe Discovery Multisensor Detector consists of optical smoke and thermistor temperature sensors which give both a combined signal as well as a separate heat signal for improved false alarm management. The Discovery Multisensor construction is similar to that of the optical detector but uses a different lid and optical mouldings to accommodate the thermistor heat sensor.The Discovery OpticalHeat Multisensor Detector contains an optical smoke sensor and a thermistor temperature sensor whose outputs are combined to give the final analogue value.

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 micro-controller processes the two signals according to the mode selected.When the detector is operating as a multisensor i.e. modes 1 3 and 4 the temperature signal processing extracts only rate-of-rise information for combination with the optical signal. In these modes 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.Response ModesMode 1 has very high smoke sensitivity combined with high heat sensitivity. This gives a high overall sensitivity to both smouldering and flaming fires.Mode 2 has a smoke sensitivity similar to that of a normal optical smoke detector. This mode is therefore equivalent to a standard optical detector. It is suitable for applications in which wide temperature changes occur under normal conditions.Mode 3 has moderate smoke sensitivity combined with a moderate sensitivity to heat. This combination is considered the optimum for most general applications since it offers good response to both flaming and smouldering fires.Mode 4 has lower than normal smoke sensitivity combined with high heat sensitivity. This makes it suitable for applications in which a certain amount of fumes or smoke is considered normal.Mode 5 has no smoke sensitivity at all but gives a pure heat detector response meeting the response time requirements for a Class A1R detector in the European Standard EN 54- 5. In this mode the detector will respond to slowly changing temperatures and has a fixed temperature alarm threshold at 58OC. The analogue value in this mode will give the approximate air temperature over the range 15OC to 55C. In Mode 5 the smoke sensor is still active though it does not contribute to the analogue signal. As a consequence if the detector is used in a dirty or smoky environment the optical sensor drift flag may be activated in the heat only mode.Key FeaturesIdeal for a wide range of applicationsEnhanced false alarm managementRecommended in specific modes for hotel bedrooms and hospital wardsUnaffected by wind or atmospheric pressureWell-suited to sensitive environmentsFive EN 54 approved response modesHeat only and optical only optionsRemote test feature
