P/N 761011-02
Congratulations on your purchase of a Velox to G-Shield Fire Upgrade kit. Gastech has
built on the foundations of the Velox system to bring you an enhanced vehicle mounted
gas detection system. The G-Shield Fire will detect carbon monoxide (CO) and hydrogen
cyanide (HCN).
1. Introduction
2. What’s in the box
The upgrade kit includes:
• One replacement Printed Circuit Board Assembly (PCBA) for the
touchscreen
• Two G-Shield Sensor Platforms fitted with dummy plugs
• One CO G-Pod
• One HCN G-Pod
• USB cable
• This instruction guide
• Software (Download directly from https://gastech.com/g-shieldfire)
• 1.3 mm hex wrench for Bushing Nut grubscrew
WARNING: The G-Shield Fire must be installed by an approved person.
Incorrect installation can cause injury or death to personnel.
3. Safety Precautions
The upgrade of the Velox system to the G-Shield Fire involves multiple steps. The
suggested workflow is shown below.
1. Removal of the Velox hardware
2. Upgrade of the touchscreen (new PCBA and software updates)
3. Installation of the G-Shield Fire hardware
4. Response test of the G-Pods
4. The Upgrade Process
The Velox used a single power connection. The G-Shield Fire requires two
power connections to be made to the G-Shield Fire PCBA plus a ground
connection. Please refer to the wiring diagram in section 14.
CAUTION:

5. Removal of the Velox system
WARNING: The Velox system must be removed by an approved person. Incorrect
removal can cause injury or death to personnel.
Please return these obsolete parts to Gastech for responsible disposal.

Figure 3. Velox Touchscreen PCBA image.
The removal of the Velox system is not covered by these instructions.Note:
You must de-energise the existing Velox gas detection system before it is
removed to avoid damage to the touchscreen.
CAUTION:
The existing Velox wiring may be retained and re-terminated if desired.Note:

6. Touchscreen display hardware upgrade procedure.
The touchscreen display must be configured to operate as a G-Shield Fire device. The
Velox PCBA must be carefully removed and the information stored in the touchscreen
display must be updated.
The touchscreen is reused for the G-Shield Fire and must be retained.
Do not lift one side more than the other. Small movements are best. The PCBA
must be removed without excessive force to avoid damage to the touchscreen
connector pins.
CAUTION:
Figure 4. G-Shield Fire Touchscreen PCBA image.
Figure 5. Spudger inserted - top view.
Lay the touchscreen display face down on a soft cloth with the Velox PCBA facing
upwards.
Step 1.
Carefully insert a suitable spudger between the touchscreen display and the PCBA.
Work the spudger around the gap and gently lever the two items apart.
Step 2.
Make sure the pins are undamaged.Step 3.

11. Sensor Platform Installation
The G-Pod sinter must face towards the ground. Sudden pressure changes can cause
a loss of accuracy.
CAUTION:
Do not exceed 20 Nm when the Mounting Nut is tightened. Damage can be caused to
the gasket.
CAUTION:
You can use Loctite® 243™ Threadlocker to make sure the nut does not loosen because of
vibration.
Note:
The Splash Guard protects the G-Pod from wind and water to the ingress protection
level IPX6 and must always be fitted.
CAUTION:
Figure 21. Sensor Platform exploded diagram.
Install the Sensor Platforms vertically at the rear of the vehicle. Make sure the
G-Pod sinter faces downwards.
Step 1.
Use the M25 x 1.5P thread to attach the Sensor Platform to the vehicle.Step 2.
Torque the Mounting Nut to between 12 Nm and 20 Nm. Gastech recommends
finger tight and 3/4 of one turn.
Step 3.
Figure 22. Typical installation to bracket
The gasket must be fitted between the mounting bracket and the communication
bushing as shown
CAUTION:

12. Sensor Platform Maintenance
You will notice some resistance as air is expelled from between the G-Pod and the Sensor
Platform. This is normal.
Note:
Do not over tighten the grubscrew. The grubscrew can damage the threads on the
Sensor Platform.
CAUTION:
Sensor Platforms are supplied without a G-Pod installed. Make sure you install a
G-Pod.
CAUTION:

Align the key on the G-Pod with the keyway on the Sensor Platform. Push the
G-Pod into the Sensor Platform.
Step 1.
Fit the bushing nut. The Bushing Nut attaches the G-Pod to the Sensor Platform.Step 2.
Step 3. Tighten the grubscrew using the 1.3mm hex wrench supplied in the upgrade kit.

13. G-Pod Installation
Do not try to attach the Splash Guard when a Dummy Plug is installed as it will not fit.CAUTION:
Make sure you replace the G-Pod with a Dummy Plug (P/N 65-2000-00) during
maintenance.
Step 1.

14. Wiring Diagram
Use stranded tinned copper conductors in a PVC jacket. Cable size of 16 AWG to 22 AWG is
suitable. The maximum allowable outside diameter (OD) is 6.5 mm. Use insulated bootlace
ferrules to avoid damage to the copper conductors.
15. Cable Information
Use four core sheathed cable between the touchscreen and the Sensor Platforms. The
maximum cable length permitted is 20 m.
You can use equivalent alternatives for this item.Note:
Figure 26. G-Shield Fire system wiring diagram.
J3 and J4 are interchangeable.Note:
Gastech recommends inline fuses for both power feeds. Refer to figure 26 for
the fuse values.

16. Touchscreen Electrical Connections
The touchscreen has 2 inputs for power. VBAT supplies constant power to the Sensor
Platforms. VBAT connects internally to VOUT+ on the sensor RS-485 connection. Constant
power is necessary for the G-Pods. ACC supplies power to the touchscreen.
Connect the vehicle accessories circuit to ACC. The touchscreen will turn on and o with
the vehicle ignition.
Connect the vehicle battery input to VBAT.
The G-Shield Fire can be installed into vehicles with a 12V DC or 24V DC electrical system.Note:
