Apollo Series 65 Optical Smoke Detector with Flashing LED 55000-316APO

Apollo Series 65 Optical Smoke Detector with Flashing LED 55000-316APO

Apollo Series 65 Optical Smoke Detector with Flashing LED 55000-316APOThe Series 65 Optical Smoke Detector incorporates a pulsing LED located within the housing of the detector. The external detector moulding is identical to that of the ionisation detector and has an indicator LED which is clear in quiescent state but produces a red light in alarm.OperationThe Series 65 Optical Smoke Detector has a moulded self-extinguishing white polycarbonate case with wind resistant smoke inlets. Nickel-plated stainless-steel wiper contacts connect the detector to the base. Inside the case a printed circuit board has the optical system mounted on one side and the signal processing electronics on the other. The sensing chamber is a black moulding configured as a labyrinth which prevents penetration of ambient light.The labyrinth has a fine gauze insect-resistant cover. The chamber houses an infrared light emitting diode LED and a photo-diode which has an integral visible-light filter as extra protection against ambient light. Every three seconds the LED emits a burst of collimated light modulated at 4kHz. In clear air light from the LED does not fall directly on the diode because the LED is positioned at an obtuse angle to the diode. When smoke enters the chamber a fraction of the collimated light is scattered onto the photo-diode.If the resulting signal from the photo-diode is above a pre-set threshold the LED emits two more bursts of light this time at two-second intervals. If light is scattered onto the photo-diode by both these pulses due to the presence of smoke the detector signals an alarm state by switching the alarm latch on increasing the current drawn from the supply from about 40A to a maximum of 75mA. This fall in the impedance of the detector is recognised by the control panel as an alarm signal. The alarm current also illuminates the detector integral LED. A remote indicator connected between the L1 IN terminal and the R terminal will have a voltage equal to the supply voltage less 1 volt across it and so will illuminate.To ensure correct operation of the detector the control panel must be arranged to supply a maximum of 33 Volts dc and a minimum of 9 Volts dc in normal operation.The supply may fall to 6 Volts dc in alarm conditions if a supply current of at least 10mA is available at this voltage. To ensure effective illumination of the integral LED and any remote indicator the supply to the detector should exceed 12 Volts. To restore the detector to quiescent condition it is necessary to expel any smoke and interrupt the electrical supply to the detector for a minimum of one second.Key FeaturesResponds well to slow-burning smouldering firesWell-suited to bedrooms and escape routesUnaffected by wind or atmospheric pressureFlashing LED and magnet operated test switch option

Apollo Orbis Optical Smoke Detector with Flashing LED ORB-OP-12003-APO

Apollo Orbis Optical Smoke Detector with Flashing LED ORB-OP-12003-APO

Apollo Orbis Optical Smoke Detector with Flashing LED ORB-OP-12003-APO OperationApollos Orbis operates on the well-established light scatter principle. The remarkable optical design of the Orbis optical smoke detector allows it to respond to a wide spectrum of fires. The sensing chamber of the Orbis optical smoke detector contains an optical sensor which measures back-scattered light as well as the more usual forward-scattered light. Sensitivity to black smoke is greatly improved.The detector is calibrated so that Orbis is highly reliable in detecting fires but is much less likely to generate false alarms than earlier smoke detectors. The stability of the detectorhigh reliability low false alarm rateis further increased by the use of algorithms to decide when the detector should change to the alarm state. This removes the likelihood of a detector producing an alarm as a result of smoke from smoking materials or from another non-fire source.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 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
