528 Series Expansion Microphone Station

The IEDA520FME-H is an expansion station that interfaces to a 528 series microphone station through an IEDA528E expansion board. Up to three (3) expansion stations can be connected to a parent station to expand paging capability of the system. Each expansion connects to its parent station using Category 5e or better cabling and utilizes the parent station’s CPU and Ethernet interface to transmit announcements through the system.

Each expansion station has a push-to-talk (PTT) switch located on the hand-held microphone. This PTT switch is directly tied to the PTT switch on the parent station so the PTT functions are identical between the parent and all slave stations. The PTT switch can be configured to initiate a live or a recorded announcement. A user can go to the parent 528 series station or any of the expansion stations and achieve the same announcement results by simply picking up and keying the microphone.

The IEDA520FME-H can be mounted in a standard 2-gang electrical box or to a 528 series backbox using the optional IEDA528SKA adapter plate. The optional IEDA528SKBB backbox can be purchased to mount the unit on a standard single-gang electrical box or on the IEDA520DTB desktop base for desktop mounting.
