P&ID Balloon for AutoDialer

We often use an Autodialer to dial an operator phone in the event of a Level High High condition. In the past we've never made reference to the AutoDialer on our P&IDs except to mention it in our Interlock Schedule. What ISA letters would be the most correct to use in an instrument bubble to represent the AutoDialer?

Thanks
