Notifier SD-851TE Conventional Multi Detector

Notifier SD-851TE Conventional Multi Detector

Notifier SD-851TE Conventional Multi DetectorThe SD-851TE photoelectric smoke thermal detector incorporates an optical chamber and a thermal element which in turn are continually monitored by an on board processor by using algorithms developed specifically for the unit. An alarm signal is only enabled in the detector once the processor is satisfied that an actual fire has been detected. By using a combination of inputs the incidence of nuisance alarms is reduced while at the same time the response time to an actual fire is also improved.A variety of detector bases are available providing compatibility with a wide range of Fire Alarm Control Panels making it ideal for expansions and retrofit applications. The remote hand-held programming tool can also be used in conjunction with the PhD series of detectors to gain access to other enhanced features. The features available include readwrite last maintenance date read chamber contamination level read value of thermal element and perform an alarm test.Key FeaturesAutomatic drift compenstationProgrammable SensitivityAdvanced maintenance features via remote hand-held test unitLow profile designLow current drawWide operating voltage 8 to 30VDCBi-colour LED detector status indicatorAddressable alarm location featureApproved to EN54 part 7 20003 Year warranty

Apollo Discovery Marine Multisensor Detector 58000-700MAR

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

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 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 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
