Det-Tronics X3301 Multispectrum IR Flame Detector with Pulse Output - Manual (Page 5)

3 95-8528 11.1
During the entire test, the detector gives no indication
of alarm.
To reset the controller status and alarms, place the
keylock switch in RESET. Return the keylock switch to
NORMAL when testing is complete.
The Man oi test is nearly identical to the Mag oi test,
except for the manner in which the test is initiated:
• Place the keylock switch on the controller (R7404/
R7494) in the TEST position.
• Press the SELECT button to select the appropriate
detector for test.
• Press the TEST/ACCEPT button to initiate the test.
Controller and detector responses are identical to the
Mag oi test described above.
To reset the controller status and alarms, place the
keylock switch in RESET. Return the keylock switch to
NORMAL when testing is complete.
NOTE
Refer to Appendix A for FM verification of the
oi function.
COMMUNICaTION
The X3301 is furnished with an RS-485 interface for
communicating status and other information with external
devices. The RS-485 supports MODBUS protocol, with
the detector configured as a slave device.
DaTa LOggINg
Data logging capability is also provided. Status
conditions such as normal, power down, general and
oi faults, fire alarm, time and temperature are recorded.
Each event is time and date stamped, along with the
temperature and input voltage. Event data is stored in
non-volatile memory when the event becomes active,
and again when the status changes. Data is accessible
using the Inspector Connector accessory or RS-485.
INTEgRaL WIRINg COMpaRTMENT
All external wiring to the device is connected within the
integral junction box. The detector is furnished with four
conduit entries, with either 3/4 inch NPT or M25 threads.
DETECTOR SENSITIvITy LEvELS
There are four factory configured sensitivity levels
available for the X3301 Flame Detector:
Very High, Medium, Low and T-Low.
The following criteria should be considered when
choosing a sensitivity level for the intended application:
• Detector placement
• Speed of response based on fuel type and fire size
(see Appendix A for response times)
• Distance between the hazard and the flame
detector
Recommended sensitivity guidelines are as follows:
Very High:
Offshore, Warehousing
Medium: General Duty, Compressors
Low: Offshore, close proximity/high IR
backgrounds
T-Low:
Turbine Enclosures
Additional information on X3301 Flame Detector
performance results and sensitivities can be found in
Appendix A, the FM Approval and Performance Report.
Consult the factory with any questions on how to choose
the optimum sensitivity level for the intended application.
