INSTALLATIoN
NOTE
For complete information regarding performance,
installation, operation, maintenance and
specifications of the FlexSonic Acoustic Detector,
refer to instruction manual 95-8657.
No special or additional detector installation
requirements exist above and beyond the standard
installation practices documented in the FlexSonic
Acoustic Detector instruction manual.
Environmental operating specifications for the FlexSonic
Acoustic Detector are applicable as published in the
general specifications section in the instruction manual.
The device shall not be exposed to environments that
exceed its specified environmental limits.
The FlexSonic Acoustic Detector operating power
distribution system should be designed and installed so
the terminal voltage does not drop below 9 Vdc when
measured at any specific location. The external system
providing power to the FlexSonic Acoustic Detector
must have over-voltage protection that ensures supply
voltage does not exceed 30 Vdc.
The user shall correctly install all shielding and
grounding for device and ensure that maximum cable
lengths are not exceeded.
NOTE
All safety functions of the FlexSonic Acoustic
Detector are active within 30 seconds of power-
up without any user action required.
CoMMoN MISUSE SCENARIoS
Refer to the Installation, General Application Information,
and Maintenance sections of the instruction manual for
information on avoidance and resolution of common
misuse scenarios. No special application restrictions
are necessary to meet the safety certification
requirements.
NOTE
If the user suspects that damage or misuse has
occurred to the FlexSonic Acoustic Detector, a
full proof test shall be performed.
GENERAL APPLICATIoN CoNSIDERATIoNS
– The user shall understand the effects of and limit the
number of devices that are voted to declare alarm.
– The user shall understand the effects of the time
delay parameter and limit the length so that desired
SIF hazard detection is achieved. Alarm time delay
should be sufficient to prevent false alarms from
friendly or known gas releases (e.g. intermediate
process venting normal to SIS operation).
START-UP AND CoMMISSIoNING
Commissioning Personnel
The Safety Certified FlexSonic Acoustic Detector
can be commissioned by any qualified person with
knowledge of acoustic detection instruments and the
configuration device being used.
Refer to the Installation section provided in the FlexSonic
Acoustic Detector instruction manual for details.
Configuration
A HART handheld or RS485 communication device
can be used to monitor internal status or to modify the
factory settings of the FlexSonic Acoustic Detector.
Refer to the FlexSonic Acoustic Detector HART
Addendum (number 95-8698) for guidance on using
HART communication.
Alternate protection measures must be used as needed
while modifications to safety related parameters are
being made, including while the device is in learn mode.
Cloned configuration data as well as learn data should
only be used at the exact physical location that it was
developed.
The device must be powered down during SD card
removal and installation.
While in the process of calibrating the 4-20 mA output,
the detector is not able to signal an alarm. During this
time, the device is not performing its safety function.
The periodic AIC frequency / fail count combination
must allow for fault indication within 1 hour or less (e.g.
a configuration of 10 minute intervals and consecutive
fail count of 3 will cause a fault in 30 minutes).
