An Garda Siochana require Text Alert groups to complete a one-page TA1 form, which basically lets your district station know who they should contact when they are sending out alerts. We tell you exactly what to include on the TA1 and we provide a print-friendly version on our website. We make this task as simple as possible. All you will need to do is print the document, sign it, and return it to your district Garda Station.
