It was developed to detect the characteristics of fire in a wide range of applications, and to avoid deceptive alarms. The modern design of both measurement systems and the analysis of the parameters by means of a special algorithm allow to reliably evaluate the characteristics of fire. This makes it an all-rounder that is used in virtually all fields of fire detection. An internal drift compensation adjusts the alarm threshold by continually evaluating the contamination of the detector. With that, the sensitivity of the detector is kept constant for a long time. The thermal sensor complies with Class A1R according to EN 54-5. The detector can therefore be used in rooms with a maximum height of 7.5m. Addressable conventional technology is used for alarm transmission to the fire detection control panel. The detector addressing can be achieved in 2 ways: • A detector with an Address Module NG58-1 can be individually identified by the suitable control panel. • 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 Programming and Test Unit S300RPTU can also be used to set and display the following detector parameters: • the sensitivity in 3 levels, • the detector address, and • the date of the previous maintenance. Furthermore, the degree of drift compensation (detector contamination) and the current condition of the detector can be read out. The detector can be attached to various detector bases and it can be protected against theft. Building Safety.
