.1    This Clause contains a comprehensive range of field devices listed alphabetically by ``Point type'' code,
       not all of which will necessarily be applicable to this project. Refer to the ``Point Type'' column on the
       points lists in Section 15930 to identify the devices relevant to this project

.2    Some point types have a number as the last character in order to identify variations in a group of similar
       field devices. For each separate point type or group of similar devices (common point type except for
       number) all items provided shall be the product of one manufacturer.

.3    All field devices shall be selected to have full compatibility with the SAPs, TUCs or other controls
       components being proposed.

.4    Any field device proposed for use which is not one of the products listed under ``Standard of Acceptance'
       will be evaluated by the Owner's representative against the specified technical performance and the quality
       and characteristics of the products which are listed. If any proposed field device is deemed not equivalent
       to the specification, then the contractor will be given one opportunity to propose another device which does
       meet specification at no cost.

.5    The proposal must include technical data for all field devices listed in the points lists, specifically
       cross-referenced to the particular point type to facilitate an unambiguous proposal evaluation.

.6    Some devices may require different ranges, capacities, etc. in particular applications, even though the device
       or component is otherwise the same. Where definition of such variations is required in the specifications or
       points lists, the point type will use suffixes, for example ``DPS/x'' or ``DA1/x''. The suffixes are explained in
       the ``Technical Performance'' portion of each point type specification.

.7    The end-to-end accuracy required for analogue devices shall include the combined effect of sensitivity,
       hysteresis, linearity and repeatability between the measured variable and the output at the operator interface
       device, or between the panel signal to the digital-to-analogue converter and the controlled variable.

.8    Devices shall meet the specific requirements listed, and shall be compatible with respect to power supply,
       signal characteristics, or other factors with the CCS being proposed. Power supplies shall be provided as
       required for any and all devices.
