It is recommended that control panels and all connected detectors are commissioned upon
installation and serviced every 6 months by an IGD trained technician. IGD can offer full training to
enable your staff to do the servicing or offer a competitive service from our fleet of service
engineers.
This product must be earthed in accordance with local safety regulations.
Standard options are indicated in the basic specifications on page 4

The control panel may be stored at temperatures between 0 C and 55 C. If stored at low temperatures
and then brought into a warmer environment, condensation may form on some components. In such a
situation , this condensation should be allowed to evaporate prior to use of the equipment. If stored at
high temperature, care should be taken to ensure that humidity condensation does not enter critical
electrical components, for example the power supply.

Warnings and Performance Statements
The Tocsin 750 and 650 series control panels use the latest technology 2-wire addressable
highways to control gas detectors and associated accessories. Providing an extremely flexible and
low cost solution.

Brief Introduction
Jog Wheel Interface
Service & Maintenance
The Control Panel leaves the factory configured for the supply voltage stated on the customers order.
Should the control panel be used in conjunction with portable generating equipment, care should be
taken to ensure that the electrical supply is within the tolerance band described above.
o
The Control Panel is designed to operate within specification for ambient temperature between 0 C
o
and 55 C, relative humidity up to 95% ( non-condensing ). Sensor specifications may differ.
Do not use a Control Panel for protection applications that has not been calibrated. If calibration seals
are missing from the control panel or have been tampered with or broken, then the control panel must
be re-calibrated and sealed by a trained engineer.
Substances and interfering gases can cause adverse effects on the performance or electrical safety of
the gas detection systems. Care should be taken to limit exposure to these poisoning substances, for
further advice and information contact head office
The response time of the entire system is determined by the time of response of all the parts of the
equipment within the gas detection system.
The relationship between the output signal and the gas concentration is linear, the control panel
interprets the signal and the gas level is displayed on the HMI or RGB backlit display. IGD hold
evidence of this linear performance which is available upon request.
We recommend users read the procedures described in BS EN 60079-29-2 for reference.

Gas detection systems must be correctly specified, installed and maintained in order to be effective.
Anyone undertaking elements of this work should have access to the necessary equipment and be able
to demonstrate competence. This will usually mean having passed a training competency course.
International Gas Detectors run training courses for safety survey, specification , installation and
service aspects of hazardous gas detection systems. In addition IGD can supply test equipment and
calibration gases necessary to undertake this work.
1. A zero grade gas usually instrument air or Nitrogen and a suitable calibration gas mixture is required.
Please the following points
2. The correct gas adaptors must be used to apply gases to detectors when zeroing and calibrating.
Incorrect application of gases can affect calibration results
3. Use equipment and gases traceable to a national standard. Any calibration will only be as good as
the equipment and materials used.
4. IGD supply fixed flow regulators for use with IGD calibration gas bottles which supplies gas at
0.5L/Min

Installation Guide
Failure to follow correct installation may result in poor performance and/or damage to system
components.
Copies of the installation guide are available in the downloads section of our website. Always check
you are using the latest versions of the supplied manuals by checking on the IGD website.
Your 750 Series control panel has been supplied with a separate installation guide. Please read this
before installing your system. The Installation guide provides information for correct cable selection,
how to correctly install cables and devices and ensure correct cable segregation. It is important to
read and understand this document prior to installation.

It is recommended to follow the set up sequence below when configuring and installing a control
panel from new.
Perform a sensor FIND and automatically install detector data. Engineers Menu .... Find Option
With Sensors and Relays Installed download the panel setup to IGD’s Panel Seup App to configure
the system. It will be necessary to upload this once completed and re-start the controller for it to take
effect.
Perform a Relay FIND
Allow the system to run for at least an hour to allow detectors to fully stabilise to the site conditions.
Should any detectors require re-calibration
Detectors are supplied pre-calibrated. Follow the Bump Text video on the IGD online Academy to
check both detector calibration and to prove the system programmed cause and effect. Ensure all
interfaces to third party devices and systems function as required. Note that individual relays can be
directly energised and de-energised to aid checking
Ensure there are no indicated system errors in normal operation.
Zero each connected detector. User Menu ZERO
Calibrate each detector. User Menu CALibrate
Note IGD calibration and gas adaptor kits are available and necessary to perform calibration and
bump testing. Record all results for traceability.

Putting Into Service
Note that this product should be supplied via a fused spur. Ensure cables used are suitable for both
their intended area of operation and load capability. This product should only be installed by a
competent person.
If you are uncertain how to zero/calibrate or locate your gas detectors and system components then
use IGD’s online training academy.
If your application is safety related you must ensure you are a competent person with demonstrable
training. If in doubt check with IGD for help and support.
Follow the 2-Wire Installation guide
if you don't have a copy of this download it from www.internationalgasdetectors.com
This provides location as well as cabling/installation guidance.
Failure to observe correct installation can have an adverse affect on system operation
and performance
To set alarm levels and programme the required cause and effect you will need to
access the controller using IGD’s Panel Setup App for Android. Download the Panel
Setup App from the Google Play Store to a suitable blue tooth enabled tablet or
Phone. Android 4.1.1 or later operating system and min 7” display recommended.

WARMUP
600s
With power applied the system should undertake its power up sequence and
then commence a warm up period. The warm up period is there to allow
connected detectors to stabilise before operation. Note that certain detector
types, Oxygen sensors in particular may take up to 2 hours to fully stabilise.
During the warm up period check that each connected detector or device has power and
communication. The following diagram shows the three main terminal PCB types for detectors and I/O
interface nodes and the relevant check points.
Warm Up Period
In normal operation mode the TOC-650 communicates to each detector or node in turn and displays the
data on screen. Pressing the button once will activate the back light, each button press then cycles the
display through each channel.
For example a three channel system with a Flammable gas detector, a Carbon Monoxide Detector and
an Oxygen detector would read as:
With sensors connected and after the TOC-650 controller has completed its warm up the operating
system will go to normal operation mode.
