A.3.2.3

HART Protocol

The HART protocol is a digital communication signal at a low level on top of the
0

–

20mA. This bi-directional field communication protocol is used to communicate

between intelligent field instruments and the host system. HART is available in
wiring options 2 and 3.

Through the HART protocol the detector can:

•

Display setup

•

Reconfigure setup

•

Display detector status and definition

•

Perform detector diagnostics

•

Troubleshoot

For more details refer to

HART Manual TM777030

A.3.2.4

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.

A.3.3

Heated Optics

The front window can be heated to improve performance in ice, 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 3 ways:

•

Off

: The optics are not heated

•

: 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

–

86°F /

–

30°C. The detector stops heating the window when the temperature is

27°F/15°C above the start temperature.
