Optical Smoke Detecto e Addressable conventional technology e Sensitivity selectable in 3 steps e Addressing by means of address module or detector parameterisation e Remote readout of detector condition e Extremely flat design e Function testable with Remote Test Unit ECO1O0ORTU The Optical Smoke Detector 2351E uses the scattered light principle and was developed for the detection of smoke particles in a wide range of fire detection applica tions The modern design of the measurement chamber allows to reliably evaluate the characteristics of fire An internal drift compensation adjusts the alarm thres hold by continually evaluating the contamination of the detector With that the sensitivity of the detector is kept constant for a long time Addressable conventional technology is used for alarm transmission to the fire detection control panel The de tector addressing can be achieved in 2 ways e A detector with an Address Module NG58 1 can be individually identified by the suitable control panel e An address which has been stored in the detector by means of the Remote Programming and Test Unit is displayed on the Zonal Display Unit S300ZDU A test activation of the detector can be carried out using the Remote Test Unit ECO1000RTU In addition to the test activation of the detector the Remote Program ming and Test Unit SSOORPTU can also be used to set and display the following detector parameters e the
