103 Overview and Introduction
3 Overview and Introduction
3.1Description of Product
The Searchzone Sonik is an advanced ultrasonic gas leak detector for use in hazardous areas. It detects high pressure gas leaks within
the protection area, in order to provide an early alert to a hazard. While the Searchzone Sonik does not indicate the type of gas, it will
respond to any high pressure gas leak within the coverage area and so will protect against the release of dangerous gases, whether they
be toxic or flammable.
With conventional gas detectors, the escaping gas has to reach the detection point or line between a transmitter/receiver pair. The
Searchzone Sonik ultrasonic gas leak detector recognizes sound emitted by the leak from a distance, without the released gas having to
reach the detector.
3.2Description of Function
The Searchzone Sonik detects pressurised gas leaks by sensing the airborne acoustic ultrasonic sound pressure wave and signature
produced by the escaping gas. The detection method uses a robust patented piezo-based sensor which will function in extreme weather
conditions, on and offshore. With no moving parts and no sensor cover required, the Searchzone Sonik can withstand adverse conditions
including pressure wash-down. The detector does not require field calibration, only periodic bump testing, which can be accomplished
from ground level. Interfacing for set-up, commissioning and maintenance can be achieved wirelessly using the Searchzone Sonik App,
running on a suitable Bluetooth-enabled mobile device.
3.3Applications
The Searchzone Sonik detector is ideal for detecting gas leaks from units such as metering skids, compressors, pumps, valves and
pipework flanges in complex and congested distribution, process and transmission systems.
3.4Sensor Technology Description
The Searchzone Sonik detector employs an advanced ultrasonic sensor module that is robust and reliable even in harsh environmental
and operational conditions. The sensor module has a very long life in these adverse conditions and does not require field calibration.
The sensor detects the ultrasonic sound pressure waves, which are longitudinal vibrations that propagate through the air. Upon entering
the sensor structure, the sound pressure waves create a voltage across the transducer, which is then amplified and processed using
advanced detection algorithms. The patented piezo-based ultrasonic sensor module is robust with minimal failure modes.
3.5Environmental Factors
The leak detection range is limited by the atmospheric absorption of the ultrasound. This absorption increases with frequency. The
Searchzone Sonik will detect specified gas leaks typically up to 20m in all conditions. Background noise levels also have an effect
on the detection range. Process equipment which generates ultrasonic noise will need to be considered when setting the detection
thresholds of the detector, which can cater for high, medium and low levels of background noise. The detection range of the detector will
be maximal at lower levels of background ultrasonic noise. Typical sources of background noise include rotating machinery, clanking
chains, steam whistles and other steam release mechanisms, air horns as well as intentional gas releases.
Note
Ice build-up on the face of the sensor will cause an increase in sensitivity, which may lead to an increase in nuisance alarms. When
mounting in locations where ice build-up is likely, take necessary precautions in protecting the unit against such build-up and/or setting
of alarm levels.
3.5.1Introduction to Background Noise and Interference
The frequency of the noise being produced by the source will also have a bearing on the measurement range since the attenuation
co-efficient of sound in air increases with frequency. This not only affects the sound pattern generated by a gas leak but also that
generated by other sources of ultrasonic noise and they differ. The Searchzone Sonik detection is optimized to detect gas leaks in real
Searchzone Sonik − Technical ManualPN 2331M1220 Issue 1 11/2018
Page 11
113 Overview and Introduction
world conditions. The sound pressure level generated by a high pressure gas leak is dependent upon the pressure, the leak diameter, and
upon the gas density. The Searchzone Sonik detector is designed to detect hazardous high pressure leaks.
As a guide, the following table indicates typical maximum detection ranges that can be achieved for various levels of background
ultrasonic noise.
Detection Threshold Level 64 dB (Low) 74 dB (Mid) 84 dB (High)
Standard Detection Mode 24 m 12 m 7 m
Focus Detection Mode 7 m 5 m 3 m
Note
Due to variances sound level intensity generated across the measured frequency range and angular positioning of the detector.
The above values may vary up to 50%.
The values in the table above were achieved with a methane leak, mass flow rate of 0.1 kg/s at an environment of 20°C, 50 %RH and a
standard atmospheric pressure of 1013 hPA.
Note
The Background Levels feature, available in the Searchzone Sonik mobile App, can be used to validate and check that the current
detector settings are appropriate. Refer to section 9.9 Detector Settings for more information.
3.6Range and Field of Coverage
The Searchzone Sonik detector has a dynamic range of 40dB to 140 dB giving a detection range of typically 20m on-axis radius
(background noise dependant). The field of detection coverage (FoC) is +/90 degrees in both horizontal and vertical planes measured
on-axis to the face of the detector’s sensor.
The detection algorithms (Standard or Focus) differentiate between leak signatures and typical noise source signatures in both time and
frequency domains. The polar plots in the Figures 3 and 4 below show the typical detection areas for both Standard and Focus modes.
Refer to the table in section 3.5.1 for typical ranges that can be achieved for both Standard Mode and Focus Mode.
3.6.1Standard Mode
Use Standard Mode for larger areas which are subject to lower levels of background noise and where nuisance alarms sources are not
expected.

3.7Description of Gas Leak Detection Using Ultrasound
A high pressure gas leak is a broadband continuous phenomenon. This gas leak ultrasound signature is detected in the presence of
other ultrasound noise sources using advanced detection algorithms. The detection algorithms differentiate between leak signatures
and typical noise source signatures in both time and frequency domains.

154 Siting considerations
4 Siting Considerations
When designing an installation for a Searchzone Sonik detector it is important to give due consideration as to where it is to be located,
what potential sources of problems that may be encountered in the intended location and how the detector is to be mounted.
Users are strongly recommended to consult with experts who are experienced in site mapping and siting of ultrasonic gas leak detectors
when determining final positioning.
4.1Safety Case Framework
In compliance with IEC 61508, IEC 61511 and EEMUA recommendations, the Safety Case Framework is used as a method of
reducing risks at hazardous installations to acceptable levels. The framework is based on the concept of Layers of Protection which is
widely recognized by the process industry and clearly defined in industry safety standards.
Considering the application of all types of the protection layers − some layers are preventative (e.g., emergency shut down), while
some are there to mitigate the impact of an incident should it occur (e.g., fire and gas protective systems or plant emergency response
systems). Other layers of protection can counter occurrence of incidents in the first place (e.g., plant and physical asset protection,
constraint and boundary management, operator training, and asset management); while others can provide detection and alerting, and
associated guidance (e.g., operator alarms, early event detection, and integrated operator procedures). Layers can either be automated,
such as emergency shut down (ESD) equipment, or require human interaction such as operator responses to process alarms. Some
layers offer easily quantifiable risk-reduction benefits but require that the risks all be identified before. And still others are less tangible
and offer subtler benefits.
An Advanced Ultrasonic Gas Leak Detector will generally be used as part of a Gas Detection and Mitigation layer. Ultrasonic gas leak
detectors complement point and open path gas detectors as they detect the gas leak by sensing the sound pressure level created by a
high pressure gas leak. Ultrasonic gas leak detectors are affected by environmental conditions but not significantly by wind.
4.2Siting the Detector
CAUTION
1. Do NOT install in areas where detector can be struck by falling objects.
2. Do NOT site the detector where maintenance may impact, misalign or damage the detector.
3. Avoid installing on a vibrating infrastructure.
4. Install the detector a minimum of 1 m away from potential source of gas leak. Point the detector
30 degrees away from the potential source of gas leak.
5. A detector installed a minimum of 3 m away from a potential source of gas leak may be aimed directly
at it.
6. Do NOT operate the detector outside of the allowed temperature range. Refer to the Specification
section of this manual for more information.
Searchzone Sonik − Technical ManualPN 2331M1220 Issue 1 11/2018
Page 16
4.2.1 Mounting Position
It is recommended that Searchzone Sonik is placed close to the area to be protected to maximise the detection performance. For best
performance, use the following location principles when determining final positioning of the detector:
• Avoid situations were a leak plume is presented directly to the face of the detector. For best results, aim the detector at the potential
leak but at an angle of approximately 30 degrees off axis of the resultant plume.
• When monitoring a pipe containing the pressurized gas, mount the detector so that it ‘looks’ along the pipe.
• Avoid mounting the detector directly next to or over sources of ultrasonic noise e.g. compressor, gearbox, turbine, generator, etc.
• Do not install the detector next to pressurized air lines and fittings.
• Positioning the detector away from sources of unwanted ultrasonic noise will significantly reduce the risk of nuisance alarms.
4.2.2Mounting Angle
It is recommended that Searchzone Sonik is mounted pointing downwards by at least 30 degrees when used outdoors to allow the
sunshade to protect the sensor from the adverse environmental conditions.
4.3Accidental Impact
Situations where there is a significant probability of equipment, personnel or moving objects accidentally impacting Searchzone Sonik
detector should be avoided. If such locations cannot be avoided, measures including increase mechanical protection and warning
notices should be considered.
164 Siting considerations
4.4Change in Site Infrastructure
When there are changes in site infrastructure or configuration, which may introduce new sources of ultrasound, the customer should
review the existing configuration of Searchzone Sonik detectors and decide if it needs to be adapted to suit those changes.
4.5Transient Background Noise
Transient background noise from processes that release gas or steam under pressure (e.g., planned release of gas intended by the
operator) can cause unwanted triggering of an ultrasonic gas leak detector. These can be avoided by setting an alarm delay which is
longer than duration of that process operation.
4.6Location Survey
Points of consideration:
1) Assess the Risk Case
a. What is the risk?
b. What is the anticipated gas leak sound pressure level ?
c. What is the protection method?
d. What is the detection method in case of a leak?
e. How best to mitigate the risk?
2) Assess the environmental conditions before installation
3) Assess the potential sources of background noise in the area
If necessary measure these at the proposed ultrasonic gas leak detector install position
4) Assess the area to be covered by an ultrasonic gas leak detector with respect to:
a. Type of working environment
b. Local sources of ultrasounds
5) Choose an appropriate distance of the detector from the monitored area. Avoid installing the detector at or close to maximum range
to allow higher detection thresholds to be set, reducing the risk of false false alarms. See coverage diagrams specified in Overview
and Introduction section of this manual.
Searchzone Sonik − Technical ManualPN 2331M1220 Issue 1 11/2018
Page 17
174 Siting considerations
6) Choose Standard or Focus Mode with respect to the expected background noise levels and the nature of the risk to be covered.
Refer to the Overview and Introduction section of this manual for more information.
7) Choose the detector’s mounting position and angle, considering
a. Coverage
b. Ease of access
c. The direction of any potential leak. Refer to section 4.2.1 Mounting Position.
8) Ensure that the risk of physical impact, misalignment, or damage of the detector by human factor or uncontrollable events is avoided
4.7Bluetooth Considerations
1. Is use of Bluetooth permitted on the site?
2. Is the mobile device rated for operation in hazardous locations?
3. Is the Searchzone Sonik installed within 20 m from the place where operator will stand?
4. Is there direct visibility ensured between the Searchzone Sonik and the mobile device?

6.1Power Supply Requirements
The Searchzone Sonik detector requires a voltage supply of 18 - 32 Vdc (nominal 24 Vdc). Power consumption is 4 W maximum when
the internal heater is not active, i.e. for ambient temperatures above 30°C. At lower ambient temperature the internal heater is active
and power consumption may reach up to 15 W.
Ensure that the minimum required supply voltage 18 VDC is present at the detector, taking into account the voltage drop due to cable
resistance.
Note
Make allowance for the insertion loss resistance.
316 Electrical Installation
The maximum loop resistance in the field cable is calculated as follows:
As an example, V
the connected power supply or control system. Consult the manual of that equipment for this information.
CAUTION
The detector 24 V power supply and 420 mA current loop power supply must be of an isolating type
(galvanic isolation from mains, providing basic insulation) but does not need to be a Class II (SELV)
power supply.
CAUTION
If mains voltage is connected to more than one relay, all relays must be connected to the same phase
of the mains network. Using different phases is not allowed.

THIS DOCUMENT HAS BEEN GENERATED USING ADOBE
INDESIGN AND MUST ONLY BE UPDATED BY INDESIGN
The Searchzone Sonik features HART communications to provide access to the detector from a control system or hand-held device for
the purpose of configuration and to provide status and diagnostic information.
The total load resistance for the 420 mA current loop shall be less than 600 Ω, including the resistance of the 420 mA cable and
input impedance of the equipment to be connected. To ensure reliable HART communications, the minimum loop resistance is 250 Ω.
If HART communications is not required, the minimum loop resistance is 100 Ω.
If the 420 mA current loop is not used, a jumper must be connected between 420 mA+ (terminal 5) and 24V DC+ (terminal 8) and a
load resistor must be connected between 420 mA (terminal 6) and 0V DC (terminal 9). It is recommended to use a 470 Ohm, 1/4 W
resistor (250 to 400 Ω if HART is required). With the 420mA current loop configured this way the HART facility can still be used with a
HART hand held unit using terminals 20 and 21 inside the wiring compartment.
CAUTION
The maximum permissible mA loop voltage is 32 VDC and the maximum current is 22 mA.
6.3Relays
The Searchzone Sonik detector features 3 SPDT relay outputs for alarm and fault indication. Relay 1 is for alarm level 1, relay 2 is for
alarm level 2, and relay 3 indicates faults. The fault relay is normally energized and when energized indicates proper operation (no faults
present).
In the event of power failure or fault, the COMNO connection will open (the fault relay may be user configured as normally deenergized.)

6.5Cabling Recommendations
The cable used must be appropriate for the hazardous area classification and must meet local, national and company regulations. The
use of industrial grade, screened field cable is recommended.
An example may be a 3-core copper cable with screen (minimum 90% coverage) and suitable mechanical protection (e.g. steel wire
armour) to suit an M25 or 3/4” NPT gland entry or conduit, suitable when mA loop and Modbus are used while relay outputs are not
utilized.
The allowable conductor size for the terminals is 0.25 – 2.5 mm² (24 - 12 AWG). The Searchzone Sonik terminals will accept only wire
sizes (solid-core or stranded) in this range. The temperature rating of the conductors and cable glands should be greater than 80°C. The
terminals should be torqued between 0.5 Nm to 0.6 Nm (0.3680.442 lb.ft).
Ensure that the cable gland is installed correctly and fully tightened. All unused cable/conduit entries must be sealed with a suitable
certified blanking plug. Use appropriate and certified cable glands, adapters and/or cable fittings to meet local standards.

Page 38
7.5Delay Time
A delay time is used to minimize the possibility nuisance alarms and/or when immediate response is not required.
The delay time setting should be assessed with regards to the following:
• Searchzone Sonik proximity to monitored object/area or to the source of ultrasonic noise
• The gas type being monitored and the potential severity of a resultant leak
• Existing site protocols and local regulations
The Searchzone Sonik raises two types of alarm:
1) Alarm 1 − suspected alarm activated instantaneously after the measured sound pressure level exceeds the alarm threshold, and
is maintained above the Alarm 1 level. At this point, the delay time is applied. If Alarm 1 is still active after the delay time has passed,
Alarm 2 is activated.
2) Alarm 2 − confirms Alarm 1. Following activation of Alarm 1, the delay timer starts. If an alarm signal is still present after this time
then Alarm 2 is activated.
The delay time is set by user within range from 1 to 600 seconds. Refer to the Mobile App section of this manual for more instructions.

8.2.2mA Loop Status
The Searchzone Sonik is equipped with a 420 mA loop output which can operate in source or sink mode. Source and sink modes are
configured by wiring. For more information see the wiring diagram in Electrical Installation section. This output is a safety-related output
and is compatible for use in SIL 2 applications. Normal operation and alarm conditions are indicated between 4 to 20 mA, depending
on configuration.
The mA Loop offers two modes of operations:
1) Proportional to the detected sound pressure level.
2) Discrete, where the output will switch between distinct levels, based on detector status.
Fault and Inhibit indications are signalled with values lower than 4 mA, Over-range indications are signalled with value higher than
20 mA. Output levels of the 420 mA loop are configurable,
See the following table for output levels:
Mode Default Value (mA) Min Value (mA) Max Value (mA)

8.2.3Relay Signalling
The Searchzone Sonik is equipped with three independent relays, designated for Fault, Alarm1 and Alarm2. These relays are safetyrelated outputs and are compatible for use in SIL1 applications. The Fault relay is used for indication of various fault conditions; the
Alarm1 and Alarm2 relays are used to indicate alarm conditions. All the relays are configurable, giving an option of Normally Energised
/ De-energised and latching / non-latching of events.
CAUTION
Fault relay will be triggered when user performs Inhibit operation.
8.3Normal Operation
During normal operation, the 420 mA output represents 0 100% sound pressure level range, depending on the selected mode and
the SPL level.
The output is:
1) Linear within the range of SPL in Proportional mode
2) 4 mA in Discrete mode
Analog outputs lower than 4 and higher than 20 mA represent diagnostic information. The fault relay in this mode is normally energized
and the visual indicator is lit steady green.
8.4Operation During Fault
If Fault is indicated the visual indicator starts to flash in yellow, the fault relay is de-energized and 420 mA loop is set to 1 mA.
NOTE:
HART communication requires >1 mA current output to support transmission. If the fault level is configured to be below 1 mA, HART
communications will cease.

The Searchzone Sonik App is an Android-based mobile application that is used to configure and commission
Searchzone Sonik detectors.
CAUTION
The Searchzone Sonik App has been designed and tested to run on the Ecom SmartEX 01
mobile phone. Operation on other mobile devices is possible.
9.1General User Access
There are three methods of accessing detector from the mobile device:
1) Normal access. The user is registered and associated with the company account to which the detector is registered,
and has Internet access.
2) Off-line access. The user is registered and associated with the company account to which the detector is registered,
but has no Internet access at the time of connection. The user must periodically log in to the App when Internet
access is available, to maintain the security certificate.
3) Ad-hoc access. The user is registered, but not with the company account associated with the detector. The user
must have access to the detector Serial Number and Activation Key in order to access the detector. This access is
only available when no Internet connection is available, or the device’s Internet access has been disabled. This type
of access is not intended for normal day-to-day use.
42
Access should be granted only to suitably trained and accredited engineers.
A user of the system is able to:
1) Commission (set-up) the Searchzone Sonik – the App connects to the detector using Bluetooth and takes the user
to the commissioning work flow.
2) Create and manage other users. The App allows user to access the user management features after successful
authentication and login.
9.2Terminology
Admin User The user who initially creates a Company account and registers
a detector to that account is created as an Admin user for the
company.
An Admin user can invite further individuals as users, using the
App. The new users will become Admin users once they have
been validated.
Visitor A user who creates an account but does not register a detector
remains a Visitor.
Searchzone Sonik − Technical ManualPN 2331M1220 Issue 1 11/2018

9 Mobile App
9.3Communications
User creation requires the Sonik Searchzone App to be installed on a suitable Android device featuring Bluetooth and
an Internet connection.
9.3.1Company Account Management
The Initial Admin User is considered the first user who is registered that will go on to create a Company group. Once
done, they will then be able to create and invite subsequent users to that Company group.
In order to create this initial Admin user, they will need to register at least one Searchzone Sonik detector with their
account. The account creation will not be completed until this is done.
Note
It is not possible for an existing user to be added to a new Company Group. Please use the Add User function in the
User Management section of the App to add additional users to the Company group, using a new email address.

10 Communications
10.1HART®
CAUTION
Read the section below if HART communications are being used to communicate with Searchzone Sonik.
General
Searchzone Sonik can communicate using the HART protocol, which provides digital communications superimposed on the standard
analogue output. More information about the HART protocol can be found at the HART Communication Foundation’s website
www.fieldcommgroup.org.
HART is a master-slave protocol, i.e. Searchzone Sonik does not continually transmit data but will respond on request.
Searchzone Sonik has a HART Device Description (DD) file, which is available to download from Honeywell Analytics website
www.honeywellanalytics.com or the HART Communication Foundation website www.fieldcommgroup.org.
The DD file is written using HART version 7, and is compatible with HART DD Tokenizer versions 6 and 8.
The DD file is supplied in .fm6, .fm8, .hhd and .hdd versions. It is compatible with a wide range of industry standard products.
6710 Communications
To use the HART communications, load Searchzone Sonik DD file into a suitable HART host (see manufacturer’s instructions).
The secondary master can be a handheld terminal. The detector has been tested with the handheld Emerson field communicator.
Connection
It is best to use a dedicated HART interface point to connect a HART master (primary or secondary).
If such an interface is not available, it is possible to connect to HART signal across a load resistor in the current loop, point-to-point
mode. For example, provided there is the minimum resistance of 250 Ω in the 420 mA loop, the HART handheld device can be
connected across the terminals in the junction box.
CAUTION
If using multi-drop mode, the mA output cannot be used to provide a functional safety rated output

10.1.1 Searchzone Sonik HART Interface
Access Levels and Password Protection
The Searchzone Sonik user interface recognizes three login profiles. Default profile ‘Guest’ offers limited access rights. The second
profile ‘Engineer’ is available to wider engineering personnel. The third profile ‘Honeywell Engineer’ is restricted to Honeywell Field
Service personnel.
The default ‘Guest’ profile is read-only and displays information about the current gas leak reading and detector status, including active
warnings and faults.
The ‘Engineer’ profile access is required to test the detector, and to make changes to the default configuration.
The ‘Engineer’ profile access is password protected (8 digit alphanumeric, case sensitive). To avoid potential compatibility issues
between different HART host devices, ensure that a full 8 digit password is used.
The password is factory set to 00000000 (eight zeroes). Instructions to change the password are given below.
NOTE
Some HART handheld devices will retain the previous login until switched off, even if Searchzone Sonik is disconnected. Ensure that
‘Engineer’ profile access is protected from unauthorized use by logging off when appropriate.

10.5Modbus
The Searchzone Sonik detector provides a facility for Modbus digital communication between Searchzone Sonik and an external
controller. Modbus is a widely-supported digital data communication protocol that provides a standardised set of data communication
protocols. The principal features of the Modbus Interface are:
• Operates as a Modbus Remote Terminal Unit (RTU) slave device node.
• Supports functions 03 and 06 of the Modbus protocol.
• Provides gas leak sound pressure dB reading and alarm status for Inhibit, Fault, Alarm and Warning.
• RS485 half-duplex communication with multi-drop capability.
• Asynchronous serial link configurable for baud rate and parity.
NOTE
The Modbus broadcast commands are not supported and will be ignored.
10.5.1Programming the Host
The host computer system must be programmed to interpret the signal and status data received from Searchzone Sonik as there is no
standard Modbus format for the communication of data from gas leak detection systems.
7810 Communications
It is recommended that the host computer system should, as a minimum, be programmed to use Function 03 to collect alarm and
status data from Searchzone Sonik.
Full details of the Modbus protocol can be found in the Modicon Modbus Protocol Reference Guide PIMBUS300 available at
www.modbus.org.
CAUTION
Some transceiver manufacturers assign RS485 pin A as data positive and pin B as data negative. You
may have to transpose TDA and TDB (A in and B in) if your Modbus does not work as expected.
10.5.2Addressing Conventions and Register Values
The addressing conventions and register values used follow those set by Modicon.
4xxxx – The Holding registers are used to read Searchzone Sonik alarm status and few configuration parameters. An address range is
used to query the event record and store the result.
The write-only registers can be written singly using Function code 06.
Modbus communication settings can be updated using the write registers.
10.5.3Modbus Cables
The cable should be an RS485 shielded data communication cable suited to the installation distance, ambient and environmental
factors.
Note:
• Spurs shall not be longer than 1m (39 in.) each, and shall not exceed 10m (33 ft.) combined total.
• The maximum cable length without line repeaters is 1.2km (3900ft).
• The minimum wire size is 1.5 mm2 (15 AWG), maximum is 2.5 mm2 (13 AWG).
Searchzone Sonik − Technical ManualPN 2331M1220 Issue 1 11/2018
Page 79
10.5.4Modbus Electrical Connections
Modbus connections are provided through the terminals in the wiring compartment of the Searchzone Sonik detector. Details of the
wiring connections can be found in section 6.4.1 of this manual.
10.5.5Modbus Termination Resistor
If Searchzone Sonik is the last node in a Modbus system highway a 120 Ω termination resistor between A and B must be fitted to avoid
reflections on the RS485 circuit.
Note
The 120 Ω termination resistor is NOT supplied.
10.5.6Modbus MultiDrop Mode
A maximum of 32 nodes (31 slave nodes plus one master node) are supported in a multi-drop installation.
10.5.7Modbus Protocol
Authoritative information on the Modbus protocol can be found at www.modbus.org.
Supported baud rates are 9600 and 19200 with 9600 as the default (none parity, 1 stop bit) and slave addressis set as 1 by default.
Status reading and configuration of important parameters (adjustable with the Searchzone Sonik Mobile App and HART) can also be
performed using the Modbus interface. This appendix describes only how to monitor Searchzone Sonik status using Modbus.

11 Maintenance
The Searchzone Sonik detector should periodically be inspected, cleaned and tested. The required frequency of inspection will depend
on the hazardous area risk and maintenance plan. Please refer to IEC/EN 60079292 or other local or national regulations for
guidance on establishing an appropriate maintenance routine.
The detector requires little maintenance other than occasional cleaning. Depending on the local regulations and site conditions,
cleaning and functional testing of the detector can be carried as described in the following sub-sections. The detector should remain
powered during these procedures.
CAUTION
The Searchzone Sonik does not contain any user serviceable parts. Do not open the main enclosure.
Doing so will invalidate the warranty.
CAUTION
Seek authorized service in case of detector failure or malfunction.
8411 Maintenance
Note
The Searchzone Sonik detector requires no calibration. Periodically perform a proof test on the detector.
11.1Inspection and Cleaning
CAUTION
Do not use solvents or abrasives on the Searchzone Sonik unit.
1) Inspect the Searchzone Sonik unit and cabling for signs of physical damage.
2) Clean any dust or dirt from the Searchzone Sonik unit using soapy water and a soft cloth.
11.2Periodic Proof Test using a Canister of Compressed Air
Using a mobile device running the Searchzone Sonik App, connect to the Searchzone Sonik detector. If required, place the detector into
an inhibit state.
Obtain a full canister of compressed air.
Stand directly in front of the Searchzone Sonik detector at a distance of no greater than 5 m (16.4 ft).
Depress the nozzle of the compressed air canister to open the valve. Check that the Searchzone Sonik detector responds accordingly.
Note that as the nozzle cools due to the release of compressed air, the characteristics of the ultrasonic noise produced will change
significantly. Always allow sufficient time for the nozzle to return to normal temperature before repeating any tests.
If the Searchzone Sonik detector was placed in an inhibit condition for the test, use the Searchzone Sonik App to return the detector to
normal operation.
11.3Suggested Maintenance Schedule
The maintenance schedule will reflect local working environment and should be agreed with Honeywell representatives prior to
commissioning the Searchzone Sonik.

12 Problem Solving
12.1Introduction
It is recommended to use the Searchzone Sonik mobile App as the primary troubleshooting tool. Optionally, a HART hand held unit
can be used to carry out diagnostics.
Refer to the troubleshooting table below for a list of problems, possible causes and remedy actions.
Note
The Searchzone Sonik detector continues to function as a gas leak detector while indicating Warning, although aspects of its
performance may be reduced. A Warning is an indication of a potential future problem.
CAUTION
1. Searchzone Sonik does not contain any user serviceable parts. Do not open the main enclosure. Doing so will invalidate
the warranty.
2. If a problem persists please contact Honeywell Analytics for advice, using the contact details given on the back page.
Have the following information to hand:
- A description of the application and the problem, including the steps taken in attempt to resolve it
- The serial number of the Searchzone Sonik unit (see the label on the end cap)
- The service log downloaded from the mobile App (refer to the Mobile App section of this manual)
8612 Problem Solving
If connected to Searchzone Sonik using HART, search for the following information by selecting Device Info from the
Device Setup menu:
- Dev id (unique Searchzone Sonik identification number)
- Fld dev rev (revision number of the HART DD file)
- Software rev (Searchzone Sonik software revision number)
- Hardware rev (Searchzone Sonik hardware revision number)
3. Flamepaths are not to be repaired.
4. The equipment shall be connected to circuits providing Overvoltage Category II or better according to IEC/EN 606641.
5. To minimize the risk of electrostatic charge, provisions shall be made for an adequate grounding of the equipment,
including accessories (e.g. sunshade). Equipment shall be installed in a manner so that accidental discharge shall not
occur.
CAUTION
Some types of faults and warnings will latch the 420 mA output and need to be cleared by a Reset, which will clear
latched events. Faults and warnings will fail to clear if they are still active.

External ambient temperature is below
55°C or above +75°C
Check the ambient operating temperature. When Ex
certified equipment is operated outside its certified
range, its type approval certification is invalidated along
with its warranty. Such equipment should be removed
from service in potentially explosive atmospheres
External ambient temperature is below
30°C but above 55°C
When external temperature is below 30°C the detector
appears as not being powered during its warm-up
phase. LED status indicator is powered off, relays
de-energized and mA output is 0 mA. Internal heaters
are active and after a heat-up period the detector
initiates standard start-up cycle. Warm-up period
duration depends on external ambient temperature, to a
maximum of 30 minutes at 55°C. A good indication of
the heaters being active is the detector increased power
consumption of approximately 15 W

Fault / Problem Description Remedial Action
420 mA output is in fault 420mA loop wiring has been disturbed Check 420mA loop is correctly connected and
terminated
Reset the fault using the App or HART
If the fault persists, power cycle the detector
If the fault still persists, contact Authorized Service
Detector indicates Fault
following an over-range
condition
After over-range cleared, detector
indicates Fault for another 30 seconds
The over-range condition indicates that the detector
was exposed to an extremely high sound pressure level,
normally indicating a large gas leak. This should be
immediately investigated. The fault indication is an
intended result of the detector reporting over-range
and will clear automatically 30 seconds after the alarm
condition is cleared
Modbus communication error Incorrect communication connection Check that detector RS485 A and B wires have been
connected to the correct terminals of the controller
Check if baud rate is set up correctly
Check if data format is set up correctly
Check if address is set up correctly
Detector is not powered up Check that power is available and to specification
No termination of long cable run For cable runs longer than 100 m use termination
resistors 120 Ohm connected between RS485 A and B
wires at each end of the communication bus
Incorrect wiring topology Check that any spurs are less than 1 m in length and do
not exceed the total length limit of 10 m.
Detector gives nuisance
alarms
Alarm threshold set too low Use the background noise feature on the mobile App to
determine peak background noise. Adjust threshold to
be at least 3 dB above the current peak level
Delay parameter set too short Determine any intermittent noise sources. Set detector’s
delay parameter longer than duration of the nuisance
noise sources
Operating Mode set incorrectly Select appropriate Operating Mode as per product
siting considerations
Detector fails to raise alarm Alarm threshold set too high or Delay
parameter set too long
Review product settings and its position against the leak
source
Operating Mode set incorrectly Select appropriate Operating Mode as per product
siting considerations
The Searchzone Sonik Mobile
App reports do not show time
