how to hook options.php

Hi!
I set up multi-site and added custom menu page into admin side, and I want to edit options.
Users of new sites must have an Editor role. So they can’t to edit my options, because them can edit only super admin

$capability = 'manage_options';
if ( is_multisite() && !is_super_admin() && 'update' != $action )
	wp_die(__('Cheatin’ uh?'));

Do anybody know any way to hook the capability of options.php to be able to edit this options.
Here is the full code.

add_action('admin_menu', 'mp_change_defaults');
function mp_change_defaults() {

    //create new top-level menu
    add_menu_page('Xxxxx Partners Page Settings', 'Xxxxx', 'edit_pages', __FILE__, 'mp_settings_page', plugins_url('/images/xxxx.png', __FILE__));

    //add_submenu_page( __FILE__, 'Xxxxxx Partners Settings', 'Settings', 'administrator', 'mp_settings', 'table');

    add_action( 'admin_init', 'register_mp_settings' );
}

function register_mp_settings() {
    register_setting( 'mp-settings-group', 'partners_twitter' );
    register_setting( 'mp-settings-group', 'partners_linkedin' );
    register_setting( 'mp-settings-group', 'partners_facebook' );
    register_setting( 'mp-settings-group', 'partners_rss' );
    register_setting( 'mp-settings-group', 'partners_website' );
    register_setting( 'mp-settings-group', 'partners_blog' );
}

function mp_settings_page() {
    ?>
    <div class="wrap">
    <h2><?php _e('Partner Social Links'); ?></h2>
    <form method="post" action="options.php">
    <?php settings_fields( 'mp-settings-group' ); ?>
