General Information
The Model 013-02-0095-002 Elemec3 System Controller is the central component of an Elemec3 central
amplifier system, processing all operations through its highly configurable system software. It is
designed to be installed in a standard (19-inch) Elemec3 system control cabinet.
The Elemec3 System Controller provides continuous monitoring functions for up to 16 Microphone
Access Panels and sends/receives data from the Elemecplus Power Amplifiers, to provide complete high
integrity system monitoring, from microphone panel to loudspeaker. The integral software audio players
and the Elemec3 System Controller to amplifier audio paths are also monitored.

The system provides two internal audio paths to enable simultaneous broadcast of audio to distinct output
zones. For ease of installation and maintenance all cabinet internal connections are on a plug/socket
basis.
The software control is designed to be as flexible as possible, and can easily be configured via the TCP/IP
network connection on the rear of the Elemec3 System Controller using the Elemec3 Console software
application. Hot standby amplifier control is provided so that a powered spare amplifier(s) is
automatically connected to the loudspeaker network of the failed amplifier(s).
PABX access and Page/Party®access are configured so that telephone/intercom inputs can be digitally
stored and replayed to completely eliminate the possibility of acoustic feedback between telephone/
intercom and local loudspeaker.
Up to 256 individually programmed relay outputs and 256 input contact points are available through the
LAN interface on the rear of the Elemec3 System Controller. Duplicate Elemec3 System Controller can
be used for additional redundancy. System status, including current audio activity, faults, input, output
and amplifier states, are monitored via the TCP/IP network connection using the Elemec3 Portal software
application.
The Elemec3 System Controller is exclusively designed for use in an Elemec3 system and is not intended
for use with other types of equipment.
Important Safety Instructions
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding type plug has two blades and a third grounding
prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit
into your outlet, consult an electrician for replacement of the obsolete outlet.

9. Only use attachments/accessories specified by the manufacturer.
10. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid
injury from tip-over.
11. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or
objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.
Front Panel Indicators & Control
The Elemec3 System Controller front panel is equipped with an alarm switch, three LED indicators and a
USB port (reserved for future use). The switch allows the operator to switch off and on specific inputs.
The LEDs indicate whether the page system is in use, the power is applied to the unit, and whether the
system is operating normally or has a fault condition.

Component Description
Digital PCBA Central processing unit and digital communications
Analog PCBA Provides speech recording and play-back to eliminate feedback.
Telephone Interface PCBA Interface from Elecmec3 System Controller to telephone system
Elemec3 Fuse PCBA See “Specification” section for description
The Elemec3 System Controller contains an internal clock that continually runs in the background. It is
has a battery back-up and the time is used as a time stamp on event logs when the status of the system
changes, such as an alarm event.

Installation
Mount the Elemec3 System Controller in the 19-inch rack using the supplied hardware.
The following is a discussion of the types of Elemec3 systems that can be configured. Refer to your
system manual for complete information.
Single System
In a single type system, the Elemec3 System Controller is typically installed in the top position of a
standard EIA 19-inch Elemec3 system equipment rack. It requires 1U (1.75 inches) of height.
Duplicate System
In a “duplicated” or redundant system, two Elemec3 System Controllers, designated as A and B, are
located in system racks at different location. In this type of system there are two sets of amplifiers (also
designated as A and B) with the two speaker loops run in different routes. If one Elemec3 System
Controller should fail, there would be a 50% loss of audible coverage.
Hot Standby (N+1) System
In a different type of redundant system, referred to as a Hot Standby (N+1), two Controllers, designated
as A and B, are located in the same cabinet and control a single set of amplifiers. The advantage to this
type of system is that there is no loss of coverage if one Elemec3 System Controller should fail.

Operation
NOTE:Each Elemec3 System Controller is custom-configured for a specific application via the Elemec3
software application. Please refer to your system manual for more information.
The Elemec3 System Controller front panel contains a rotary key switch, three LEDs and a USB port
(reserved for future use).
The key switch provides the capability to turn on or off previously configured inputs.
The LEDs operate in accordance with the following table:
Table 2. Front Panel LED Indications
LED Indication
PA IN USE Green – Indicates the PA system is in use.
Off – Not in use
SYSTEM STATUS
Green – Normal operation
Red – Fault condition – Refer to the display for additional information.
Blinking Red – Fault acknowledged
Amber – Non-critical fault
PWR Blue – Power is on.
Off – No power
The E3 Controller has been designed so that it can be monitored over an IP based data network either
locally or remotely. The loss of connection to the data network therefore constitutes a fault condition
which will be duly indicated by the SYSTEM STATUS LED on the front of the Controller. For the
correct operation of the E3 Controller it should be connected at all times to a network.
