If you want fixed location based on address:

Admin->Settings->Company contact->Check “Use as map center”->Save

If you want fixed location with additional configuration, you can do following:

If you want lock map to specify location, in ‘application/config/cms_config.php’ add line

$config['custom_map_center'] = '27.175015, 78.042155';

Where numbers represents GPS coordinates.
