Section 2
Introduction
SYSTEM DESCRIPTION
The Eagle Quantum Premier (EQP) system combines
"fire detection and extinguishing agent release" and
"hazardous gas monitoring" in one complete package.
The system is intended for use in hazardous locations
and is designed to meet the requirements of approval
agencies from around the world.
The system consists of a Controller and a number of
addressable microprocessor based field devices.
The Controller coordinates system device
configuration, monitoring, annunciation, and control,
while the field devices communicate their status and
alarm conditions to the Controller.
The EQP controller can be arranged in a redundant
configuration, thereby increasing the availability of the
system. The controllers work in “Master” and “Hot
Standby” mode.
Various combinations of field devices can be
configured as part of the system. The actual selection
depends on the requirements of the application and
the regulations that cover the type of protection
required. See Figure 2-1 for a block diagram of the
Eagle Quantum Premier system.
All field devices are tied into a communication loop
that starts and ends at the Controller. Each device
connected to the communication loop is assigned a
unique identity by setting its address switches. All
other device operation parameters are configured
through Det-Tronics “Safety System Software”. These
selections define the type of device and how it is to
operate. This system configuration data is then
downloaded into the Controller.
A programmed Controller is configured to
automatically download the configuration data into the
individual devices when they first communicate with
the Controller.
In addition to Det-Tronics advanced flame and gas
detectors, Eagle Quantum Premier offers the
capability of incorporating third party fire and gas
protection equipment into the system. These can be
either input or output devices. Typical input devices
include manual fire alarm "call boxes", heat detectors,
and analog combustible or toxic gas measurement
instruments. Typical output equipment includes
solenoids, strobes, and horns. All equipment is
monitored for wiring fault conditions.
For complete system integration, the Controller has
the capability to communicate with other systems
such as PLCs and DCSs. Different communication
protocols are supported, allowing the Controller to
communicate with other systems either directly or
through communication gateways.
NOTE
Existing Eagle Quantum eld devices such as
EQ22xxUV, EQ22xxUVIR and EQ22xxUVHT are
supported by the Eagle Quantum Premier system
(not FM Approved).
NOTE
For specic information relating to the SIL 2 rated
EQP system, refer to manual number 95-8599.
COMMUNICATIONS LOOP
Eagle Quantum Premier utilizes a Det-Tronics
Signaling Line Circuit (SLC), a version of Echelon’s
Local Operation Network (LON) customized
specifically for Eagle Quantum Premier. This network
provides several key advantages:
• ANSI/NFPA Class A, Style 7 performance of SLC
• Peer-to-peer communications
• Short message formats
• Expandability
The Controller utilizes several mechanisms to
continuously check the LON loop for fault conditions,
thereby providing the highest level of reliable
communication.
Every device on the LON loop has the ability to
communicate with the Controller at any time. This is
typically referred to as distributed peer-to-peer
communications. This design allows for immediate
alarm messages to be sent from the field devices to
the Controller.
All messages are kept short in order to maximize
network performance. This minimizes network
bottlenecks.
The Eagle Quantum Premier system is easily modified
to accommodate design changes or plant expansions.
This can involve adding LON sections, repositioning
LON sections, or removing LON sections from the loop.
There are LON communication implementation details
that affect and limit how the LON loop is changed.
Only devices that have been approved for use with
Eagle Quantum Premier can be connected up to the
LON. All approved devices have been tested and
certified to operate properly on the LON.

7.1 95-85332-2
LON COMMUNICATION HEARTBEAT
The Controller continuously broadcasts a heartbeat
signal over the LON loop. This heartbeat is used for
verifying the integrity of the LON loop and for keeping
the field devices from going into a fault isolation
mode. Once every second, the heartbeat contains the
current time and date, which are used by the field
devices to log status events and calibrations.
The Controller continuously tests LON continuity by
sending out a heartbeat on one LON port and then
listening for it on the other LON port. The Controller
also broadcasts the heartbeat signal in the opposite
direction around the loop. This ensures that all field
devices, the LON Network Extenders (NE), and
communication wiring are correctly passing the digital
information around the loop.
The field devices use the heartbeat as a mechanism
to ensure that there is a communication path back to
the Controller. If the field device does not receive a
heartbeat for a period of time, the device will go into a
LON fault isolation. In this situation, the device opens
one side of the LON and listens for a heartbeat on the
other side. If the device doesn’t receive a heartbeat, it
listens on the other side of the LON and opens the
opposite LON connection.
THEORY OF OPERATION
During normal operation, the Controller continuously
checks the system for fault conditions and executes
user defined programmed logic that coordinates the
control of the field devices. At the same time, the field
devices are continuously monitoring for device based
fault and alarm conditions.
When a fault condition occurs, the Controller displays
the fault condition on the Vacuum Fluorescent Text
Display, activates the appropriate fault LED(s),
activates the Trouble signal using the Controller’s
internal enunciator, and de-energizes the Controller’s
Trouble relay.

7.1 95-85332-3
Controller based fault conditions include the Controller
status and LON communications such as the
heartbeat being sent around the loop and the field
device loss of communications. Controller based fault
conditions are listed in Table 2-1.
Field device based fault conditions are transmitted to
the Controller, where they are then annunciated. Refer
to Table 2-2 for a listing of field device faults. Each
field device transmits its status to the Controller
on a regular basis.
When an alarm condition occurs, the Controller
displays the alarm condition on the text display,
activates the appropriate Alarm LED(s), and activates
the alarm signal using the Controller’s internal
annunciator.
Each field device must communicate alarm and fault
conditions to the Controller. The timing for transmitting
alarms and faults to the Controller is displayed in
Table 2-3.

NOTE
All fault and alarm conditions are latched on the
Controller. To reset the Controller, conditions
indicated on the text display must currently be in
the OFF state. Pushing the reset button then
initiates a Controller reset. Active alarms will
remain through a Controller reset.
CONTROLLER LOGS
The controller has an internal alarm and event log.
The logs can be accessed via the S3software
configuration ports (Configuration Port or Port 3) using
a RS-232 serial cable and a Windows™computer.
The controller can save up to 4,095 alarms and events
in the controller memory.
CONTROLLER USER LOGIC
The Controller continuously executes the user logic
programs that are programmed using S3software.
The user logic programs are set up in the same
fashion as IEC 61131-3 programmable logic
programmed into Programmable Logic Controllers
(PLCs). Block diagram logic gates are tied together
with inputs, outputs, and other logic gates to perform
a specific task. A number of tasks can be tied
together to perform a system function.
Typical programmed functions include flame/gas
voting, timing delays, timing executions, latching
conditions, alarm and trouble notification, suppression
control, condition control, and process shutdown
notification.
The Controller executes program logic by starting with
the first logic page of the first program and then
progressing onto subsequent pages of the same
program. In turn, subsequent programs are then
executed.
Every one hundred milliseconds, the Controller will
start executing the user logic that is programmed into
the Controller. Within this logic execution cycle, the
Controller will execute as many of the logic pages as
possible. If all programmed logic is executed in a
cycle, the Controller will start executing program logic
with the next cycle. Otherwise, subsequence logic
execution cycles are used to finish executing the
remaining logic gates. Only when all the logic gates
have been executed will the Controller start over. The
Controller will start executing the first logic page of
the first program at the beginning of the next logic
cycle.
COMMUNICATION NETWORK FAULT OPERATION
During normal operation, the Controller is continuously
broadcasting a heartbeat around the communication
loop as shown in Figure 2-2. The Controller
broadcasts the heartbeat in both directions. At the
same time, the field devices are transmitting status
information to the Controller over the communication
loop.
Every field device except the network extender has
two LON fault isolation relays. Each relay is tied to a
communication port on the device. When a field
device fails to receive the heartbeat from the
Controller, the device initiates a LON fault isolation
routine. The isolation routine disconnects one of the
communication ports via one of the LON fault isolation
relays. The device listens for a heartbeat on the
communication port that is connected. If a heartbeat
is not found, the routine then disconnects the other
communication port and listens for a heartbeat on the
connected side. The process is repeated until either
a heartbeat is located or a LON fault timeout period of
two hours is reached. The LON fault isolation routine
is disabled and the LON fault isolation relays are
closed when the LON fault timeout period has
elapsed. The LON fault isolation routine will be
enabled when the device again receives a heartbeat.
For a single wiring fault, the field devices with the fault
will isolate the fault by opening LON fault isolation
relays. After the field devices isolate the wiring fault,
communications will be resumed between the
Controller and field devices. Refer to Figure 2-3.
