Description

Speciﬁ cations

• Combination of optical and thermal

characteristics of ﬁ re

• Alarm temperature 58°C
• High range of radio transmission
• 2 frequency bands with

24 bidirectional data channels

• Communication with RF Interfaces

M500RFE-AS and M400RFE-AS

• Base included

The Optical-Thermal Radio Detector 2100RFT-AS uses

both an optical sensing chamber based on the scattered

light principle as well as a separate thermal max detec-

tion unit with an alarm temperature of 58°C. The detec-

tor communicates with the RF Interfaces M500RFE-AS

or M400RFE-AS via a secured radio protocol. The ac-

tivated condition of the detector is optically indicated

by an LED. The radio detector is especially suitable for

areas, where cabling is impossible or uneconomical.

4 data channels in the frequency band 868MHz as well

as 20 channels in the frequency band 434MHz are avai-

lable for the bidirectional data transmission. The avai-

lability of the channel is checked regularly. During the

learning phase of the detector, i.e., when the detector

is registered at the radio interface, a unique key, based

on a choice of several million codes, is created, which

allows the unambiguous identiﬁ cation of the detector.

Regular status messages, monitoring of the battery vol-

tage and the long life of the batteries ensure the high

reliability of the system.

The detector is designed for indoor mounting and is

delivered with a mounting base, however, batteries are

not included.
