Nittan EV-P Photoelectric Optical Detector

Nittan EV-P Photoelectric Optical Detector

Nittan EV-P Photoelectric Optical DetectorUsing a simple but effective technique the EV-P Optical Detector incorporates a chamber housing an Infra-Red IR LED light and a photodiode light detector set at an obtuse angle preventing it from seeing the light. When smoke enters the chamber the light bounces off the smoke particles and strikes the photodiode causing it to generate an alarm condition when a set threshold value is met. The EV-P Optical Detector is therefore more sensitive to larger smoke particles which tend to be caused by smouldering fires rather than fast flaming fires.Key FeaturesOptical DetectorEvolution FSK protocolEEPROM Addressed ProgrammerRIL and Base Control Outputs

Nittan RP-RS2-01NTN Conventional Indoor RESET Call Point IP24 cw Back Box and Wall Plate

Nittan RP-RS2-01NTN Conventional Indoor RESET Call Point IP24 cw Back Box and Wall Plate

Nittan RP-RS2-01NTN Conventional Indoor RESET Call Point IP24 cw Back Box and Wall PlateThe Reset Call Points are a unique call point that mimic the feel of breaking glass whilst offering the user the benefits and environmental advantages of a re-settable operating element.The Waterproof Reset Call Points are specially designed for use within harsh environments such as oil rigs ships factories as well as wash down areas that are sensitive to broken glass.They are compatible with most conventional fire alarm systems. They are safe to use in areas where glass cannot be used such as food processing plants and leisure centres.As the units can be simply reset they provide an ideal solution for areas that suffer from a high number of false activations such as schools shopping centres and other public places.Key FeaturesManual Call pointSTI RESET Housing-IP24Internal Alarm Current Limiting ResistorWide Operational Voltage Range 12v-28v

Nittan EVC-P Photoelectrical Optical Smoke Detector

Nittan EVC-P Photoelectrical Optical Smoke Detector

Nittan EVC-P Photoelectrical Optical Smoke Detector with 375 Ohm ResistorUsing a simple but effective technique the EVC-P Optical Detector incorporates a chamber housing an Infra-Red IR LED light and a photodiode light detector set at an obtuse angle preventing it from seeing the light. When smoke enters the chamber the light bounces off the smoke particles and strikes the photodiode causing it to generate an alarm condition when a set threshold value is met.The EVC-P Optical Detector is therefore more sensitive to larger smoke particles which tend to be caused by smouldering fires rather than fast flaming fires.OperationThe smoke chamber of the EVC-P is constructed so that light cannot enter from outside but smoke can pass through the chamber slots. The EVC-P utilises the light scatter sensing principle. The LED pulses every 8 seconds to maintain a low monitoring current. A quick charge time 20 seconds is also achieved. The detector incorporates an alarm verification function which requires two successive pulses before an alarm is given.The interval between the first and second pulse is automatically reduced to four seconds after the first alarm level is monitored. The detector design provides strong immunity to air velocities contamination and RF interference. The geometry of the smoke chamber and optics support assembly is designed to give the best possible signal to noise ratio resulting in excellent response characteristics.Key FeaturesOmniview 360 LEDInternal Alarm Current Limiting ResistorWide Operational Voltage Range 12v-32vOptical Detector

Nittan Waterproof Reset Call Point IP67 WRP2-R-01

Nittan Waterproof Reset Call Point IP67 WRP2-R-01

Nittan Waterproof Reset Call Point IP67 WRP2-R-01The ReSet Call Points are a unique call point that mimic the feel of breaking glass whilst offering the user the benefits and environmental advantages of a re-settable operating element. The Waterproof ReSet Call Points are specially designed for use within harsh environments such as oil rigs ships factories as well as wash down areas that are sensitive to broken glass.They are compatible with most conventional fire alarm systems. They are safe to use in areas where glass cannot be used such as food processing plants and leisure centres. As the units can be simply reset they provide an ideal solution for areas that suffer from a high number of false activations such as schools shopping centres and other public places.OperationThe ReSet uses a simple yet ingenious patented mechanism which consists of a rigid plastic operating element and an over centre spring mechanism. This arrangement provides real action on operation and simulates break glass activation. An activation indicator drops into view at the top of the window after the ReSet has been operated. The unit is then simply reset with a key and is ready for reuse straight away.Key FeaturesWaterproof tested to IP67Glass appearance maintains operator deterrencePositive activation that mimics the feel of breaking glassVisible warning flag confirms activation Simple key to reset operating element no broken glassNo glass elements to break lose or incorrectly fit during installationComplete functional test with every activationExtremely attractive high value look and feelLow profile heavy-duty terminations two built in resistor values
