•
Communication Network
: The detector is equipped with an
RS-485 communication link that can be used in installations
with computerized controllers.
The communications protocol is Modbus compatible.
•
This protocol is a standard and widely used.
•
It enables continuous communication between a standard
Modbus controller (Master device) and a serial Network of
up to 247 detectors.
Headed Optics
The front window can be heated to improve performance in icing,
condensation and snow conditions. The heater increases the
temperature of the optical surface by 5-8°F (3-5°C) above the
ambient temperature. The heated optics can be configured in three
ways:
•
Off
: The optics are not heated
•
On
: The optics are heated continuously
•
Auto
: Operated only when the change of temperature requires
the heating. (default)
In
Auto
mode the start heating temperature can be defined
between 32°F - 122°F (0°C - 50°C). The detector stops heating the
window when the temperature is 27°F (15°C) above the start
temperature.
