MULTIDROP MODE
Optical flame detectors are life safety devices
and require the 0-20 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
RS-485 Modbus communication is not
available on HART equipped models.
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 (DD)
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 DD. DD 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 X5200, ensure
that the appropriate DDs for the X5200 have been
programmed into your Communicator. To review the
DDs 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 X5200 DDs are
installed in your Communicator.
If the X5200 DDs 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
en.hartcomm.org.
DETECTOR WIRING
Refer to the X5200 instruction manual (form
number 95-8546) for complete instructions
regarding detector installation and wiring.
NOTE
X5200 detectors with HART do not support
RS-485 communication.
NOTE
Power consumption specications for the
HART model are different than the standard
model.
Power Consumption Specications of X5200
Detector with HART Communication
Without heater: 2.8 watts at 24 Vdc nominal;
4.8 watts at 24 Vdc in alarm.
3.1 watts at 30 Vdc nominal;
5.4 watts at 30 Vdc in alarm.
Heater only: 8 watts maximum.
Total power: 17.5 watts at 30 Vdc with EOL
resistor installed and heater on
maximum.
EOL resistor must be ceramic, wirewound
type, rated 5 watts minimum, with actual power
dissipation not to exceed 2.5 watts.
