Optical Smoke Detector

2351E

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.

• Addressable conventional technology

• Sensitivity selectable in 3 steps

• Addressing by means of address

module or detector parameterisation

• Remote readout of detector condition

• Extremely ﬂ at design

• Function testable with Remote Test

Unit ECO1000RTU
