Det-Tronics ATX10 Transmitter SAFETY MANUAL - Manual (Page 5)

1.2 95-8658 5
WARNING
Any external alarm equipment, systems or
signaling devices that could be automatically
initiated by performing this test must be disabled
or bypassed before performing this test!
Response Proof Test Sequence
NOTE
Verification of the LED function is optional as the
LEDs are not part of the safety function.
1. Inhibit alarm and fault response at the control
device.
2. Place the magnet at the ‘TEST’ icon on the ATX10
faceplate for at least 3 seconds or issue an Active
Manual AIC test command via digital communication
(HART or RS485).
3. Activation of the Manual AIC test results in a flashing
green LED and an audible tone.
4. Verify correct change of state at the control device:
a successful alarm proof test results in a latched
20 mA output and red alarm LED; an unsuccessful
proof test results in a latched 2 mA output and a
flashing yellow fault LED.
5. Following a Manual AIC test, reset the detector
by placing the magnet at the ‘RESET’ icon on the
ATX10 faceplate for at least 3 seconds, or by issuing
a reset command via digital communication (HART
or RS485). Actuating the Reset command resets
any alarms or faults and places the detector back in
the normal operating mode.
6. Verify that the device returns to a 4 mA output.
7. Re-activate alarm and fault response at the control
device.
Completion of the Response Proof Test must be
recorded and documented in the SIS logbook.
WARNING
Any external alarm equipment, systems or
signaling devices that were disabled must be
re-activated at the conclusion of proof testing
activities.
NOTE
The use of the Manual AIC test shall be limited to
maintenance and proof test activities.
CALIbRATIoN
Field calibration of the acoustic detector is not
necessary or available.
FAULT/FAILURE ACTIoN PLAN
In the event that an AIC test does not result in an
acceptable Response Proof Test, then the standard
Maintenance and Device Repair and Return procedures
as listed in the FlexSonic Acoustic Detector instruction
manual must be followed. Any failure to successfully
complete the Response Proof Test must be recorded
and documented in the SIS logbook.
PRoDUCT REPAIR
Field repair of the FlexSonic Acoustic Detector is
limited to replacement of the sensor cover and/or
foam particulate filter. All other device repairs must be
conducted at the factory. No firmware changes are
permitted or authorized. All failures detected by the
device diagnostics or by the proof tests that cannot
be resolved through the procedures described in
the FAULT/FAILURE ACTION PLAN section must be
reported to the manufacturer.
oPERATING, ENVIRoNMENTAL, AND
PERFoRMANCE SPECIFICATIoNS
The Safety-Certified FlexSonic Acoustic Detector
product versions fully comply with, and must be operated
in accordance with the functional, environmental, and
performance specifications provided in the FlexSonic
Acoustic Detector instruction manual. A 24 hour mean
time to repair should be assumed for safety availability
calculations.
SPARE PARTS
Refer to “Ordering Information” in the FlexSonic Acoustic
Detector instruction manual. Safety Certification is
based on a sufficient number of spares to achieve a 24
hour mean time to repair.
