- Page 2 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...
- Page 3 Doc Ref: SL-068 v1.35 pg 3 Typical Models Covered By This Manual TOC-750 Series Hazardous Gas detectors can be supplied in a number of formats. Some typical models are indicated in the diagram below. All 750 Series detectors and annunciators use a common ‘module’...
- Page 4 MKIII FLAMMABLE GAS DETECTOR SHOWN The ATEX version uses IGD’s JB3 series ATEX EXD terminal enclosure. Please note that cable glanding and sealing must conform to ATEX requirements which is more fully described in the ATEX JB3 manual. Mounting Details and Dimensions Safe Area Versions 20mm Entries Top, Bottom &...

- Page 6 Note that one 2-Wire addressable highway running Sentinel+ protocol can support up to 32 modules. Each module can have up to 8 connected devices. IGD Configuration software is used to configure the module PCB to switch devices on and off and set addresses (see Tocsin 650/750 Manual). If the connected devices have already been configured then the base address can be set from which all other...
- Page 7 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. Failure to follow correct installation may result in poor performance and/or damage to system components.
- Page 8 170mA 2.5V Note: The Pellistor ‘Type’ is selected using IGD service tool app or by using the setup routine in the TOC-750 Software. Once selected this automatically sets the head supply voltage. In operation and with zero air applied correctly to the detector the ‘balance’ between the two detector ‘beads’...

- Page 10 Doc Ref: SL-068 v1.35 pg 10 Addressing the Assembly The TOC-750 Module PCB is an Addressable Device and Comes Equipped With a Simple Interface to Allow the Base Address to be Set. To Set The Set Address, 1 2 3 4 5 DOWN Press and hold the Down button for >2s Release Button the Light Pattern Will Now Indicate the set Address as Shown in the Table Below.

- Page 12 Doc Ref: SL-068 v1.35 pg 12 Service Using IGD Android Apps IGD provide a range of Android based Apps for use with suitable tablets and mobile phones. For control panels these connect directly using bluetooth. For addressable devices it is necessary to make a direct USB cable connection using IGD’s interface cable as indicated below.
- Page 13 Doc Ref: SL-068 v1.35 pg 13 Zero and Calibration Flow a suitable zero gas (usually Nitrogen) allow the graph/reading to settle (usually 60-90 seconds) and select ZERO to zero the detector Now apply calibration gas as indicated. The graph should show the signal rise as the detector responds to gas and gives a visual indication to show when the reading has stabilised.
- Page 14 Doc Ref: SL-068 v1.35 pg 14 Detector Zero Sequence The module PCB has four inputs which can be enabled and calibrated locally using the equipment set previously described. When the module PCB is powered and as described in the indications section, the LED’s will indicate which options are enabled .
- Page 15 Doc Ref: SL-068 v1.35 pg 15 Detector Cal Sequence The module PCB has four inputs which can be enabled and calibrated locally using the equipment set previously described. When the module PCB is powered and as described in the indications section, the LED’s will indicate which options are enabled .
- Page 16 Doc Ref: SL-068 v1.35 pg 16 Reset to Defaults If required the module can be reset back to a default state. The diagram below indicates the sequence to do this. With the module powered the LED pattern indicates that the PEllistor, I/O Port 1 and the Relay are DOWN 1 2 3 4 5...
