Apollo Discovery Optical Smoke Detector 58000-600APO

Apollo Discovery Optical Smoke Detector 58000-600APO

Apollo Discovery Optical Smoke Detector 58000-600APOThe Discovery Optical Smoke Detector operates using the light scatter principle and is ideal for applications where slow-burning or smouldering fires pose a potential risk. Discovery 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.OperationThe Discovery Optical Detector has a white moulded polycarbonate case with wind-resistant smoke inlets. The two indicator LEDs are red in alarm. Within the case is a printed circuit board which on one side has the light-proof chamber with integral gauze surrounding the optical measuring system and on the other the signal processing and communications electronics. An infra-red light emitting diode within its collimator is arranged at an obtuse angle to the photo-diode. The photo-diode has an integral daylight-blocking filter.The IR LED emits a burst of collimated light every second. In clear air the photo-diode receives no light directly from the IR LED because of the angular arrangement and the chamber baffles. When smoke enters the chamber it scatters light from the emitter IR LED onto the photo-diode in an amount related to the smoke characteristics and density. The photo-diode signal is processed to provide an analogue value for transmission when the detector is interrogated.Key FeaturesResponds well to slowburning smouldering firesWell-suited to bedrooms and escape routesUnaffected by wind or atmospheric pressureFive response modesRemote test feature

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

Apollo Intelligent Auto-Aligning Beam Detector SA7100-100APO

Apollo Intelligent Auto-Aligning Beam Detector SA7100-100APO

Apollo Intelligent Auto-Aligning Beam Detector SA7100-100APOThe Intelligent Auto-Aligning Beam Detector combines a transmitterreceiver in the same detector head with an automatic alignment motor. This combination with integrated addressability allows for quick and simple installation. The Intelligent Auto-Aligning Beam Detector automatically compensates for environmental effects on the beam signal keeping the unit in the best possible working order. This is achieved through the combination of software automatic gain control and motorised realignment of the beam.OperationThe Intelligent Auto-Aligning Beam Detector is a compact detector for detecting smoke in large open areas such as warehouses theatres churches and sports centres. It comprises a ground level loop-powered controller a detector head with an operating range of 8m-50m and a single prism. The operating range of each detector head can be increased up to 100m by using the Extension Kit which comprises of three additional prisms.An additional detector head can be connected to the controller. Each head has a loop address. It also has a built in 20T negative bi-directional short circuit isolator and it is compatible with control panels using CoreProtocol Discovery and XP95 protocol. A built-in laser provides rapid initial alignment and thereafter the detector head will continuously automatically align and compensate for any building movement.The status of each detector can be monitored through the controller which is sited at ground level. The detector head operates both as a transmitter and a receiver. A well-defined IR beam is projected to a prism mounted on the opposite wall which is reflected back to the receiver. In the event of smoke partially obscuring the light an imbalance between the transmitted and received light will occur. The detector will then transmit an alarm value to the control panel.The detector is factory set to a beam obscuration of 35 which is the best setting for most factories and warehouses. The setting can be changed to 25 for offices and clean areas such as theatres or to 50 for hostile areas such as mills or foundries. The detector reports a pre-alarm analogue value 48 at approximately 75 of the alarm threshold. The detector compensates automatically for gradual contamination of the lenses in order to avoid false alarms. The detector is non-latching and resets 30 seconds after an alarm event ceases and in 3 seconds after the removal of a fault.Key FeaturesLoop Powered and compatible with XP95 Discovery and CoreProtocolIncorporates a bi directional short-circuit isolatorAutomatic drift compensationAutomatic resetGround level ControllerAutomatic alignment compensation for building movementLaser assisted alignment for quick installationAllows for 2 detector heads per controllerUp to 100m rangePre-alarm thresholdEN 54-12 and EN 54-17 certified

Apollo Marine Intelligent Base Mounted UV Flame Detector 55000-027MAR

Apollo Marine Intelligent Base Mounted UV Flame Detector 55000-027MAR

Apollo Marine Intelligent Base Mounted UV Flame Detector 55000-027MARThe Marine Intelligent Base Mounted UV Flame Detector is designed to protect enclosed indoor areas where open fires may be expected. The detector has a fast-acting response to flames up to 25m away and is equipped with a single UV sensor with a narrow spectral response in order to discriminate between flames and most spurious sources of radiation.ApplicationUV flame detectors are used when detection is required to be unaffected by convection currents draughts or wind. These include engine rooms in ships factories affected by draughts or wind and warehouses. They are fast reacting and respond to a flame more than 25m away. The UV flame detector is affected by arc welding electrical sparks lightning nuclear radiation and UV light sources. For applications where these phenomena are present a UV flame detector should not be used.OperationThe detector is sensitive to ultraviolet radiation emitted by flames during combustion. Since it requires only UV radiation the detector responds even to stationary flames with no flicker like cigarette lighters and blue gas flames.The detector is set to respond to ultraviolet radiation 185260nm emitted by almost all flames including those invisible to the naked eye e.g. hydrogen fires. The detector has a single UV sensor with a narrow spectral response in order to discriminate between flames and most spurious sources of radiation and is designed for internal fully enclosed areas. Caution The detector will also detect electrical discharges from lightning or arc welding.Key FeaturesResponds to stationary flames with no flickerSensitive to UV radiation emitted by flames during combustionCompact flame detector which fits into Discovery Marine baseLoop-powered
