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).
