IEDA524-H / IEDA520DTB DIGITAL MICROPHONE STATION
Features
The 524 digital microphone station provides immediate digitization of full bandwidth audio and transmission over a
standard Ethernet connection. It utilizes the IED 501HH teardrop handheld microphone that includes a programmable
push-to-talk button. The station uses a metal magnet landing area for the 501HH to provide a storage position for the
microphone.
In the standard configuration, it can be mounted using a standard 2-gang electrical box or a 1-gang electrical box using
the included plastic backbox. An optional weighted base (IEDA520DTB) is available for desktop mounting configurations.
Buttons
The 524 series digital microphone station features four selection buttons. These buttons are configured using the an-
nouncement controller configuration software to function as one-touch action buttons to trigger any of the following types
of announcements or messages:
•
A live page to a designated zone group
•
A recorded page to a designated zone group
•
A permanent message playback to a designated zone group (e.g., customer reminder or emergency message)
•
Any action type available in the GLOBALCOM configuration software
Network Requirements
The 524 digital microphone station utilizes CobraNet® technology licensed from Cirrus Logic®.
Live audio on the data network is time sensitive and requires minimal latency through the network to ensure uninter-
rupted audio. The 524 digital microphone station and CobraNet operate on Layer 2 (MAC Layer) of the OSI Model. This
traffic will not operate on a Layer 3 Router or above. VLAN’s (Virtual Local Area Networks) may be required for managing
traffic as well as Quality of Service (QoS) and Prioritization configuration of network switches. All connections to the 524
digital microphone station must be full duplex 100 Mbps Ethernet auto-negotiation.
