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.
