Description

The Optical Smoke Detector 2351E uses the scattered light principle, and was developed for the detection of smoke particles in a wide range of fi re detection applica- tions. The modern design of the measurement chamber allows to reliably evaluate the characteristics of fi re.

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 fi re detection control panel. The de- tector addressing can be achieved in 2 ways:

•A detector with an Address Module NG58-1 can be individually identifi ed 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 Program- ming 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 (detec- tor contamination) and the current condition of the de- tector can be read out.

The detector can be attached to various detector bases and it can be protected against theft.
