NOTE: If you are designing a new system, talk to your dealer or contact your Area Systems Engineer to learn about the advantages of using our 2-wire, 3-wire, and all-IP systems.
If you have an existing 4-wire system and need to replace a component, please contact your manufacturer’s representative or TOA Customer Service for availability.
