Aritech EV1116 16m PIR Volumetric Detector With 11 Curtains Grade 2

Aritech EV1116 16m PIR Volumetric Detector With 11 Curtains Grade 2

Aritech EV1116 16m PIR Volumetric Detector With 11 Curtains Grade 2Aritech motion sensors have the most advanced and sophisticated optics in the security industry. This unique optical mirror technology is a step and gliding focus which creates a continuous curtain resulting in a sensor that never loses track of the object.To increase detection coverage the EV1100 series sensors incorporate a 3-step gliding focus which produces 11 continuous curtains to detect infrared signals up to a 16 m distance.5D signal processing5D is the next generation of Aritech signal processing. It builds on the current strengths of 4D but adds an intelligent differentiation between fast and slow moving signals.When a slow thermal source is detected the signal processing switches automatically to the 5D mode and executes additional pattern recognition to distinct this signal from a slow walking person. If the signal fits it must be an intruder and an alarm is generated. If there is no fit the signal is ignored which ensures signals such as moving reflection of sunlight are filtered out.The result is a unique combination of high sensitivity detection with high false alarm immunity without the need for manual sensitivity adjustment.Key FeaturesPassive Infra Red motion sensor3Brid Step Gliding Focus Curtain mirrorPlug-in electronicsSealed optics5D signal processing for false alarm immunityCloak and umbrella immunityFull under crawl detectionSelectable coverage pattern using mirror masksAuto focus with constant range sensitivityNo adjustment required for different mounting heightsTolerates wall angle deviationCertified EN50131-2-2 Grade 2Several European approvals

Aritech EV1012PI 12m PIR Volumetric Detector With 9 Curtains Pet Immune Grade 2

Aritech EV1012PI 12m PIR Volumetric Detector With 9 Curtains Pet Immune Grade 2Aritech motion sensors have the most advanced and sophisticated optics in the security industry. This unique optical mirror technology is a step and gliding focus which creates a continuous curtain resulting in a sensor that never loses track of the object.To increase detection coverage the 1000 series sensors use the 3Brid orthogonal curtain design. This is a horizontal mirror structure that produces curtains with vertical orientation to detect infrared. This orthogonal invention is the key in adding curtains to the mirror without sacrificing signal strength nor increasing the size of the sensor.5D signal processing5D is the next generation of Aritech signal processing.

Apollo Series 65 Optical Smoke Detector with Flashing LED and Magnetic Test Switch 55000-315APO

Apollo Series 65 Optical Smoke Detector with Flashing LED and Magnetic Test Switch 55000-315APO

Apollo Series 65 Optical Smoke Detector with Flashing LED and Magnetic Test Switch 55000-315APOThe 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
