Patol FBS 25 Small Filter Box 25mm PC 50-0500143-01-02P

Patol FBS 25 Small Filter Box 25mm PC 50-0500143-01-02PThe filter box small is used as an accessory part for aspirating smoke detectors in areas with low temperature conditions below 0C and high dust levels to prevent false alarms and to increase the lifespan of the smoke sensors substantially.The filter insert is designed for the separation of particles and impurities. Due their particle size smoke particles can pass through this filter unhindered. Reliable and fast fire detection is thus ensured.The air polluted with dust particles is also aspirated by the aspirating smoke detector. To prevent false alarms the aspirated air must be purified of these particles. The filter box small can be used for this purpose as an additional accessory component.Key FeaturesPrevention or substantial reduction of false alarmsLengthening of lifespan of smoke sensorsVery low installation costsSubsequent installation possible at any timeLow operating costsApplicable for all aspirating smoke detectorsQuick clean and inexpensive solutionField of application deep freeze areaPipe Connection Diameter 25mmMaterial PC

Patol 5012 Stainless Steel Infrared Heat Sensor without Controller

Patol 5012 Stainless Steel Infrared Heat Sensor without ControllerThe 5000 Series is an early warning infra-red transit heat sensor which can trigger at temperatures as low as 100C when monitoring materials being transported on conveyor systems before they have reached the ember or flame condition.Its unique eight detector enhanced Infra-red monitoring has been created to detect black heat. Black body emissions occur for all material the sensor is designed to detect a change in these emissions even at relatively low temperatures when the material moves through its field of view.Air purging from a compressed air feed is used to maintain a positive air pressure in the sensor enclosure an air knife ensures the prevention of dust settling on the sensor window. The air supply is monitored by a pressure switch which on air failure is signalled as a fault status.The 5020 controller is directly connected to the sensor. A series of user programmable DIL switches allows option selection including detector sensitivity settings automanual reset sequence selection and single coincidence voting from the four individual internal detection channels for the alarm trip and shutdown outputs.The sensor air pressure and signal cable connections are fault monitored and fail safe. The controller incorporates an aux. fault input common fault output contact.

Patol Digital LDM-519-DDLX LHDC Monitor and Distance Locator 10km

Patol Digital LDM-519-DDLX LHDC Monitor and Distance Locator 10kmThe module is designed to monitor a length of Digital Linear Heat Detection Cable LHDC for both fire condition and fault status open circuit.The unit is designed such that it may be configured to operate in a two-wire mode that emulates the operation of conventional heat detectors. The unit may therefore be directly interfaced with fire control panels by connection to fire zone trigger circuits or addressable interfaces.The DDL has a 3 digit LCD which activates on fire condition and displays the distance into the zone the alarm has occurred. Digital LHDC may be employed in lengths up to 10km. The unit has an adjustment to accommodate interposing cables.Signalling of fire and fault status by means of VFC may be realised when a separate supply is employed. A 4mA to 20mA instrumentation current loop output is provided for connection to PLCs etc.Key FeaturesDisplay of Alarm Location Distance in metresFault monitoring of LHDC for open circuit conditionsLED indication of Fire Fault and Supply statusTest Reset functionsOperable for two wire fire panel conventional circuits line low powerAnalogue address loop interfaceable loop powered configurable4 to 20 mA instrumentation current lop outputLHDC hazardous area use by means of intrinsically safe Zener barriersVFC outputs for fire fault conditions selectableDin Rail mounting

Patol DTB25 PVC Dirt Trap Box 6900285P

Patol DTB25 PVC Dirt Trap Box 6900285PThe PVC Dirt Trap Box is used as an accessory part for an Aspirating Smoke Detector in areas with high dust content to prevent false alarms and to increase the lifespan of the smoke sensors substantially.When using the dust trap we generally recommend the combination with the large or extra-large filter-box.Due to the Dirt Trap Box design dust particles are deposited on the bottom due to gravity. Smoke particles pass through the Dirt Trap Box unhindered to the small size of the particles. Reliable and fast fire detection is thus ensured.The air polluted with dust particles is also aspirated by the aspirating smoke detector. So that these particles do not cause any false alarms the aspirated air must be purified of these particles.The Dirt Trap Box can be used for this purpose as an additional accessory component. This is then to be arranged in front of the filter-box in the suction pipe see project planning notice.The aspirated air reaches the Dirt Trap Box via the entry opening underneath. En-route to the exit opening above the air is separated from most of the dust particles which are deposited on the bottom of the chamber due to gravity. The gathered dust can be removed during maintenance work simply by opening the lid.Key FeaturesPrevention or substantial reduction of false alarmsLengthening of lifespan of smoke sensorsVery low installation costsSubsequent installation possible at any timeLow operating costsApplicable for all aspirating smoke detectorsQuick clean and inexpensive solution
