ambient temperature and the settled sensitivity threshold. A self-adjustment program is switched on after
entering these data into the detector memory. The self-adjustment process terminates after achieving a
reference value with
5 % tolerance. Afterwards, the decision criteria are drawn up for various fire
phenomena runs, for instance for fast or slow fire development. The data are kept in the detector non-
volatile memory and periodically checked. Any measured value change (against the assumed decision
thresholds) caused by a smoke, after triple verification, is treated by the microprocessor as a fire.
4 DESIGN
The DOP-6001 detector design is shown on Fig. 1 and Fig. 3. The detector casing, made of plastic, embraces
electronic circuits and optical elements of a transmitter and a receiver as well as a laser diode that
facilitates the detector easy optical alignment. The lenses for infrared beam focusing are covered with a
detachable filter. On the detector back side a connecting block is mounted, to connect power supply wires.
The detector is fastened to the wall with a metal adjustment basis. On the detector front part, illuminating
diodes are placed as well as the START push button that initiates the detector adjustment process.
The illuminating diode colour signals accordingly:
-
green one
–
a state of the detector self-adjustment to the detector-reflector/reflector panel
distance, when the signal level is too high;
-
yellow one
–
a state of the detector self-adjustment to the detector-reflector/reflector panel
distance, when signal level is too low;
-
red one
–
an alarm mode;
-
no light
–
a supervision mode after proper adjustment of the detector with the reflector/reflector
panel.
The START push button enables initiation of the detector adjustment process (self-adjustment) and the
detector parameters renewed set-up after optical parts cleaning works.
5 INSTALLATION
The DOP-6001 detector interoperates with a reflector panel and then its operating distance ranges from 50
m to 100 m, or with an E39-R8 prism reflector at the operating distance between 5 m and 50 m. It is
possible to install up to 64 DOP-6001 detectors in one POLON 4000 system addressable line.
The reflector or the reflector panel as well as the M42-00 00 00 service kit, containing test foils and an
adjustment mirror, are not included in the detector standard pack and should be ordered separately.
Up to 64 DOP-6001 detectors can be installed in one addressable detection line of the POLON 4000 system.
Only one DOP-6001 detector without end-of-line resistors can be installed in one conventional line.
In case the detector is seen with difficulty or is installed in a hardly accessible place, it is possible to connect
the WZ-31 additional operation indicator to be placed in a convenient and visible place.
Before installation, it is necessary to declare an alarm mode and a sensitivity threshold. The operations are
executed using appropriate jumpers placed on the back side of the detector casing, pursuant to Fig. 6. One
of the criteria taken into consideration when choosing sensitivity may be the distance between the
detector and the reflector/reflector panel, and so:
-
for a distance from 5 m to 20 m
–
18 % sensitivity is recommended;
-
for a distance from 20 m to 50 m
–
30 % sensitivity is recommended;
-
for a distance from 50 m to 100 m
–
50 % sensitivity is recommended.
It is possible to set sensitivity level experimentally: adopting it to a certain environment in the case of the
detector difficult operating conditions. The DOP-6001 detector and the reflector/reflector panel are
