reliability and reduce false alarms within the marine environment. These include drift compensation and DirtAlert®, a feature that warns Service Engineers via a flashing yellow LED that detectors need maintenance; and patented FasTest®, a procedure that takes just four seconds to test smoke detectors and confirm that they are functioning correctly.Brand FeaturesApproved for use in marine environmentsModern, low-profile designTimeSaver® Base for fast installationTransient rejection for false alarm reductionHigh humidity tolerance at up to 98% RHWide operating temperature -40°C to +70°C\u003c\/p\u003e\n\u003cp\u003eOperation\u003c\/p\u003e\n\u003cp\u003eOrbis 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 limit - the alarm level - has been reached. In the case of rate-of-rise detectors the microprocessor uses algorithms to determine how fast the temperature is increasing.\u003c\/p\u003e\n\u003cp\u003eStatic 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.ApplicationHeat detectors have a wide range of response characteristics and the choice of the right type for a particular application may not always seem straightforward.\u003c\/p\u003e\n\u003cp\u003eIt is helpful to understand the way that heat detectors are classified as explained earlier and to memorize a simple rule: use the most sensitive heat detector available consistent with avoiding false alarms.In the case of heat detectors it may be necessary to take an heuristic approach, ie, trial and error, until the best solution for a particular site has been found. The flowchart (refer to datasheet PP2479) will assist in choosing the right class of heat detector.If the fire detection system is being designed to comply with BS 5839-1: 2002 heat detectors should be installed at heights of less than 12 meters with the exception of class A1 detectors, which can be installed at heights up to 13.5 meters. OptionsThe Orbis range incorporates seven heat detector classes to suit a wide variety of operating conditions in which smoke detectors are unsuitable.The European standard EN54-5:2001 classifies heat detectors according to the highest ambient temperature in which they can safely be used without risk of false alarm.\u003c\/p\u003e\n\u003cp\u003eThe classes are identified by the letters A to G. (Class A is subdivided into A1 and A2.) In addition to the basic classification, detectors may be identified by a suffix to show that they are rate-of-rise (suffix R) or fixed temperature (suffix S) types.All heat detectors in the Orbis range are tested as static or rate-of-rise detectors and are classified as A1R, A1S, A2S, BR, BS, CR and CS.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCan be used for applications where smoke detectors are unsuitable\u003c\/li\u003e\n\u003cli\u003eIdeal in environments that are dirty or smoky under normal conditions\u003c\/li\u003e\n\u003cli\u003eRed flashing LED at StartUp confirms the device is operating\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Apollo Fire","offers":[{"title":"Default Title","offer_id":57543097024885,"sku":"ORB-HT-41004-MAR","price":24.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0050\/1216\/0612\/files\/ORB-HT-41004-MAR.jpg?v=1788386836"},{"product_id":"apollo-fire-safe-heat-detector-orb-ht-51149-apo","title":"Apollo Fire ORB-HT-51149-APO safe heat detector, White","description":"\u003cp\u003e\u003cstrong\u003ePlease note: this is a non-returnable item (excluding faulty goods)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApollo Fire ORB-HT-51149-APO is a safe heat detector from the Orbis range.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Orbis IS Heat Detector monitors temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature.
