You could use a RowTemplate, and in that RowTemplate evaluate a css class for the given row based on whatever condition you provide. The css class could then have the stylings appropriate for that row. For example, "no-alarm", or "with-alarm" could be placed on 'td' and set a background color.

Example
You can evaluate your data item in the row template and cleanly output the given class. In this example (available in the jsfiddle link below) a user has a name and age...if the age is <= 30, they get the 'underthirty' class (really it should be thirtyorunder class).
<script id="rowTemplate" type="text/x-kendo-tmpl">
<tr>
<td class='#= age <= 30 ? "underthirty" : "overthirty"#'>
<strong>#= name #</strong>
</td>
<td>
#= age #
</td>
</tr>
</script>
