Apollo Orbis A2S Heat Detector with Flashing LED ORB-HT-11014-APO

Apollo Orbis A2S Heat Detector with Flashing LED ORB-HT-11014-APOThe Orbis Heat Detector monitors temperature by using a single thermistor which provides a voltage output proportional to the external air temperature.OperationOrbis 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.

The XP95 range features two heat detectors standard and high temperature. The standard heat detector is classified as an A2S device and will report an alarm at 55C. The high temperature detector classified as a CS device will report an alarm at 90C.Brand InformationThe XP95 range of analogue addressable fire detectors uses tried and trusted technology to give the best performance and has unique features that benefit the installer and the end user. It is suitable for medium-to-large applications with simple installation requirements. As it operates using digital communication XP95 has a high immunity from corruption and is therefore often preferred in a large system where life safety is critical. XP95 products are frequently used in commercial industrial financial government ITtelecoms and healthcare applications.OperationThe XP95 heat detectors have a low air flow resistance case made of self-extinguishing white polycarbonate.

That is the optimum detector type will depend on the type of fire risk and fire load and the type of environment in which the detector is sited. For general use smoke detectors are recommended since these give the highest level of protection. Smoke detectors from the XP95 range may be optical or multisensor types. It is generally accepted that ionisation types have a high sensitivity to flaming fires whereas optical detectors have high sensitivity to smouldering fires.Key FeaturesIdeal in environments that are dirty or smoky under natural conditionsWell suited for warehouses loading bays and car-parksUnaffected by wind or atmospheric pressure

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
