Optical Filtrex Detector
FTX-P1
Description
The addressable Optical Filtrex Smoke Detector FTX-P1
uses the scattered light principle and was developed
for the detection of smoke particles in heavily conta-
minated areas. The detector is used, for example, in
industrial plants where dust is released by production
or cleaning.
By means of an integrated fan, air samples are drawn
into the sensing chamber through two separate fi lters.
The fan is powered by a separate 24VDC supply and
operates in a 15% duty cycle (5 seconds on, 30 se-
conds off), thus allowing low power consumption as
well as precise evaluation of the air samples.
The fi lters are monitored for contamination. They are
designed to let smoke reach the sensing chamber,
whereas causes of deceptive alarms (dust particles
and tiny drops of water) are kept away from it. The ou-
ter fi lter is removeable and can be cleaned or replaced
by the operator. The modern design of the sensing
chamber allows to reliably evaluate the characteristics
of fi re.
The proven ADM loop technology with System Sen-
sor/200 protocol establishes a permanent communi-
cation between the fi re detection control panel and the
detector. That ensures a periodical function testing of
the detector. In the control panel all types of fi res are
detected by continuously comparing fi re patterns.
Intelligent evaluation algorithms use the current condi-
tion of the sensing chamber to predict the likely time
of the next maintenance. Thus the alarm threshold is
automatically adjusted within the permissible range,
depending on the contamination. With that, the con-
stant response sensitivity of the detector is ensured
for the duration of its usage.
The two LEDs with 360° visibility indicate the activated
condition of the detector. The detector address is se-
lected with two decadic rotary switches, thus allowing
to change the detector without additional tools.
A detector function test can be conveniently conducted
using a magnet or test gas. The detector is attached to
the base B524FTXE.
