Det-Tronics X2200 UV Flame Detector with HART - Manual (Page 5)

multidrop mode
Optical flame detectors are life safety devices and
require the 4-20 mA loop for transmitting important
detector status data. They should not be used in
conjunction with multidrop mode. If multidrop mode is a
requirement, the alarm and fault relay contacts must be
connected directly to the safety system or fire panel for
signalling purposes.
NOTE
This addendum covers HART wiring only. Refer
to the device instruction manual for NFPA-72
compliant releasing wiring diagrams.
hArt device descriPtion LAnguAge
The HART protocol incorporates a concept called the
Device Description Language (DDL) that enables all
suppliers of HART instruments to define and document
their products in a single consistent format. This format is
readable by handheld communicators, PCs and other
process interface devices that support DDL. DDL enables
full interoperability of devices, regardless of manufacturer,
allowing full functionality from any HART device.
In the event that your Communicator does not establish
communications with the X2200, ensure that the
appropriate DDLs for the X2200 have been programmed
into your Communicator. To review the DDLs programmed
into your HART Communicator:
1. From the Main menu, access the Offline menu.
2. From the Offline menu, select New Configuration to
access the list of device descriptions programmed
into the HART Communicator.
3. Select Det-Tronics and review the list of models to
determine if the X2200 DDLs are installed in your
Communicator.
If the X2200 DDLs have not been programmed into the
Memory Module, you must use the generic interface built
into your HART Communicator.
The HART Communication Foundation manages a
library of Manufacturer Device Descriptions, which are
distributed to programming sites for inclusion in master
devices. A complete listing of the HCF DD Library is
available for download in manufacturer and device type
sequence at www.hartcomm.org.
detector wiring
Refer to the X2200 instruction manual (form number
95-8549) for complete instructions regarding detector
installation and wiring.
NOTE
X2200 detectors with HART do not support
RS485 communication.
NOTE
Power consumption specifications for the HART
model are different than the standard model.
Power consumption specifications of X2200
detector with hArt communication
Without heater: 2.5 watts at 24 Vdc nominal;
4.5 watts at 24 Vdc in alarm.
2.8 watts at 30 Vdc nominal;
5.1 watts at 30 Vdc in alarm.
Total power: 7.6 watts at 30 Vdc with EOL resistor
installed.
EOL resistor must be ceramic, wirewound type, rated 5
watts minimum, with actual power dissipation not to
exceed 2.5 watts.
