communication. The display connects to a variety of compatible detector modules via the robust
proprietary connector. An optional Remote Cable Assembly is available for mounting compatible
modules up to 10 metres from the GG2 Display.
3.2 Key Features
Certified Intrinsically Safe –Ex ia I Ma
Rugged stainless steel construction
Failsafe architecture and digital interface
Extensive self-diagnostic routines
Economical
LCD Display
4-20mA, iMAC and RS485 communication support
Compatible with a wide range of detectors:
oElectrochemical
Carbon Monoxide (CO)

4.1 General Warnings
These instructions have been designed to assist users of the GG2 Display with installation.
Before the unit can be installed, there are a number of things that need to be considered and understood
to prevent incorrect or unsafe operation of the unit or the system into which it is installed. Along with
relevant competence, and an understanding of the target application, the following points should be
considered:
Ensure that the information provided in this user manual is fully understood.
It is extremely important that the limitations and functionality of the unit are understood to prevent
incorrect installation and use from creating a potentially dangerous risk. If in doubt as to the nature of
the limitations or their implication, consult a competent authority such as a supervisor or Ampcontrol
technical representative.
Ensure that the application into which the unit is being installed has been properly
defined, designed, and approved.
Any system intended to mitigate the risk of injury needs to be properly designed and implemented.
Such a system must be the result of structured risk analysis with the outcomes used to define the
system requirements. These requirements, in turn, will guide the choice of instrumentation, logic
solvers, and actuators needed to implement the system. Understanding the needs of the system will
ensure proper selection of equipment.
Ensure that the unit will properly perform the required functions within the system
design.
It is important to understand how the unit is intended to interact with other equipment within a system.
For safe and reliable use, it is crucial that neither the unit’s logical operation nor its signalling be
compromised by incompatibilities with connected equipment. For Group I installations, a full Intrinsic
Safety Audit will be required, along with a correctly specified Safety File. Contact Ampcontrol for
engineering services to undertake these assessments.
Modifications of any form to the unit are prohibited.
The unit as supplied has been designed and manufactured to comply with the requirements of
protection and performance standards. If modifications of any form are made to the unit, the equipment
may no longer be fit for use. If any modifications or damage to the unit is evident, do not use the
equipment and contact Ampcontrol for advice.

4.2 Mandatory Installation Practices
The following information must be adhered to when installing the GG2 Display. Failure to adhere to this
information may give rise to unsafe operation.
Using the unit in a manner that exceeds its electrical, functional or physical specifications, or in a way
that is contrary to its operating restrictions, may result in equipment malfunction or loss of performance
The unit must be powered within the specified voltage range.
The installation of the unit must be carried out by suitably trained and qualified personnel.
Identification labels fixed to the unit must not be damaged, removed or covered before, during or
after installation.
The installation is to be in accordance with the relevant installation Standards/Codes of Practice.
Modifications must not be made to any part of the unit. As supplied, the unit is built to, and
complies with the relevant standards. Modifications to its construction will render the unit non-
compliant.
Complete and accurate records of the installation must be kept as part of the site installation.

WARNING!
The connections shown above are for the certified GG2 Display Module
housed within the GG2 Display.
The external connections for the GG2 Display are detailed in Section
4.5.4
4.4 Mechanical Installation Information
To ensure continued reliable operation of the GG2 Display, the following should be considered when
mounting the unit:
Select a suitable central location for mounting with good access. The location should be as clean
and dry as practicable and at a temperature as close to 20°C as practicable.
Mount the display in a position that reduces the risk of mechanical damage.
Mounting should be to a vertical surface, allowing for easy access and subsequent servicing.
The installation requirements of any connected sensors shall be taken into account

Dimensions
While mounting points are backwards compatible with Ampcontrol’s existing Gasguard equipment, the
additional space required by the GG2 Display/Sensor assembly must be taken into account during
installation. The remote head assembly will require a bracket modification to mount the detector.

Mounting Arrangements
4.4.2.1 GG2 Display
The GG2 Display is mounted using the four screw tabs. The custom plug interface allows subsequent
mounting of compatible modules. Optionally, the compatible modules may be mounted up to 10 meters
away using the optional remote cable assembly. Refer to Figure 6 for mounting hole locations.
