INTRODUCTION
Description
The IED 524 digital microphone station is a 4-button device for initiating audio/visual announcements, messages, and
pages with the GLOBALCOM and vACS Series Announcement Control Systems. It is a network appliance with a unique
IP address that simplifies installation and configuration. The 524 features four zone group selection buttons plus a push-
to-talk button located on the hand-held microphone.
Just like IED’s other digital microphone stations, the 524 uses a single Ethernet interface for audio and control data. The
524 station is fully compatible with IEEE 802.3af standard for Power over Ethernet (PoE), allowing the 524 to be powered
directly from any standard off-the-shelf PoE switch. The processing power for the 524 comes from the onboard 32-bit
processor. This powerful processor manages the input buttons, Ethernet interface, audio signal processing, and self-test
diagnostics.
This, and all IED LAN-based GLOBALCOM components, are designed to maximize the benefits of a standard 100 Mbps
Ethernet LAN based network, using off-the-shelf switches and structured CAT5e or better cabling. The 524 Digital Micro-
phone Station utilizes CobraNet® technology.

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.

INSTALLATION
IEDA524-H Attached to Standard 2-Gang Electrical Box
The IEDA524-H is designed to fit in a standard 2-gang electrical box. Install the unit into a box as shown in Figure 3. This
is the preferred installation method for wall mounting or any other flush-mount applications. When this mounting method
is used, you should remove the included plastic back box and store it for any future needs and use the included screws
for mounting the device in the 2-gang electrical box.
Figure 3 - 2-Gang Electrical Box Installation
IEDA520DTB Desktop Base
The IEDA520DTB is available as an option when a desktop mounting solution is preferred. The IEDA524-H ships with the
plastic back box that you can then use to attach the unit to the base as shown in Figure 4. The unit is then secured to the
base by tightening the retaining screws using the nuts located on the back of the base mounting plate. The microphone
station can be removed from the base by loosening the retaining screws using the nuts located on the back of the base
mounting plate. The plastic box contains keyhole slots, so you simply loosen the screws and slide the unit up to remove
it from the base. You can then access the DIP switches, connect the cable(s) and re-attach it to the base. Simply tighten
the retainer screws with the nuts to secure the unit to the base.

Alternative Single-Gang Electrical Box Installation
The IEDA524-H is shipped with a plastic back box that can be used if the installation does not allow for the recom-
mended 2-gang electrical box installation. This box can also be used if you later decide to mount the unit to a desktop
base. The box has two keyholes that fit a standard single-gang electrical box hole pattern. This allows you to install the
unit in an installation where you may already have single-gang boxes installed. The box provides a slight forward slant
which is excellent for surface mounting the unit in a console. Figure 5 illustrates the process for mounting the unit in such
an application. The washers shown are optional and can be used to prevent the unit from being forced off of the box due
to the keyhole mounting points.

Figure6illustratesanalternativemountingoptionwheretheboxhasbeenrotated180˚toprovideaslightbackward
slant to the microphone station. In this case, you must use appropriately sized washers when attaching the box to the
electrical box to prevent it from sliding off due to the keyhole mounting points. When the plastic box is attached in this
orientation, you will no longer have direct access to the DIP switches or connectors. You will need to set the DIP switches
and make any connections prior to placing the unit in the box. Use care when routing the cables as the clearance
between the connector and the box is minimal.
