Optical-Thermal Detector

2351TEM

Description

The Optical-Thermal Detector 2351TEM uses both the

scattered light principle as well as a separate thermal

detection unit. It was developed to detect the charac-

teristics of ﬁ re in a wide range of applications, and to

avoid deceptive alarms. The modern design of both

measurement systems and the analysis of the parame-

ters by means of a special algorithm allow to reliably

evaluate the characteristics of ﬁ re. This makes it an

all-rounder that is used in virtually all ﬁ elds of ﬁ re de-

tection.

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.

The thermal sensor complies with Class A1R accor-

ding 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 ﬁ re detection control panel. The

detector 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 Pro-

gramming 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 (de-

tector contamination) and the current condition of the

detector can be read out.

The detector can be attached to various detector ba-

ses and it can be protected against theft.

• Addressable conventional technology

• Combination of optical and thermal

characteristics of ﬁ re

• Drift compensation

• Sensitivity selectable in 3 steps

• Addressing by means of address

module or detector parameterisation

• Function testable with Remote Test

Unit ECO1000RTU
