2.0 EPACO SYSTEM OVERVIEW
The EPACOSystem is a modular detection
and control system combining the latest in
addressable technology with simplicity of
installation and maintenance. All system
modules are DIN rail mounted to allow for a
variety of installation options. Three (3) bus type
communication circuits tie the various system
modules into one easy to operate protection
system. A non-volatile history buffer allows for
enhanced diagnostic ability to troubleshoot
process situations. With the optional
Annunciator Module (AM), the customer has the
ability to step through a menu format to retrieve
process history without having to wait for a
service agency to arrive on site.
This manual will provide the necessary
information to properly install and monitor the
Relay Card (RC8) for the EPACOSystem.
The commissioning and service should be
performed by certified service engineers and
outlets specifically trained on this system.

3.0 SYSTEM COMPONENTS
The cornerstone of the system is the Explosion
Protection Controller (EPC). Three colored LEDs
provide instant visual indication of system
status. The DIN rail mounting allows for
flexibility when choosing an enclosure. The EPC
is an addressable panel that has the ability to
retain an event history for enhanced system
diagnostics. The EPC is a component that
allows mounting in close proximity to the
protected environment, thereby minimizing field
wiring. Shorter wire runs greatly reduce the
interference from electrical and radio frequency
sources, allowing for a much more reliable
protection system. The EPC’s detection inputs
can be programmed for pressure warning,
threshold detection, and rate of rise detection. It
also has a contact closure detection circuit to
support thermal, infrared, or other switch-closure
type detection devices1. A supervisory input
circuit is provided to monitor suppression
container pressure or other similar system status
safeguards. The EPC has a remote disable
input contact to allow for disabling the EPC from
a customer PLC or other remote device during
product loading, cleaning, or maintenance. DIP
switches allow for basic system programming.
An RS232 connection is available at each
module for connection to a PC. Using the EP
WorksTM software, an authorized user can
access system diagnostics and more complex
programming by PC.
The EPC is powered by the other key
component in the EPACOsystem, the Power
Supply Unit (PSU). The PSU has six separate
24 VDC, 1 amp power output circuits capable of
powering up to four EPCs in addition to other
components of the EPACOsystem. The PSU
has the flexibility of containing its own battery
backup supply or the customer has the option of
supplying a backup power source. The PSU
has an imbedded power shutdown procedure in
the event of AC power failure, which prevents
the backup batteries from being completely
depleted. In addition to powering EPCs, the PSU
can power an Annunciator Module (AM) and
Relay Card Modules (RC8). The power circuit
dedicated for the Annunciator Module can not be
shut off. All other power output circuits can be
shut off for service on the various system
components. The PSU may be eliminated if
1FM Approved switch closure for use with Fike threshold
detector (E61-042-x) and Rate of Rise detector (E61-056-x).
Other switch closure, thermal, or infrared devices are not
approved by FM.
battery backed, uninterrupted 24VDC, 0.500
Amps power per module can be provided by
others. For an FM approved installation without
the PSU, the uninterruptible power must be U.L.
1778 “Uninterruptible Power Systems” listed,
and conform to NFPA 72 “National Fire Alarm
Code”, NFPA 70 “National Electrical Code”
(Articles 700 and 701), NFPA 110 “Standard for
Emergency and Standby Power Systems”, and
NFPA 111 “Standard on Stored Electrical
Energy Emergency and Standby Power
Systems”.
The Annunciator Module (AM) provides a central
communication point for diagnostics. This
module will typically be installed in an area
removed from the process environment such as
a control room. The AM has two push buttons to
access the various menus and three numbered
LEDs for identification of the system statuses
within the menus.
The Relay Card Module (RC8) provides the user
with a block of eight Form “C” relays for
equipment shutdowns and remote notification of
system trouble and alarm conditions. On-board
LEDs display status for instant visual verification
of each relay. DIP switches are provided for
configuring the relay’s operation.

4.0 INSTALLATION
4.1 INSTALLATION OVERVIEW
The effectiveness of active explosion protection
systems, such as explosion suppression and
explosion isolation, depends upon the
instantaneous reaction of the protection system
and is a direct function of its speed of response.
It is therefore, critical that all possible measures
are taken to reduce the individual system
components’ response times to an absolute
minimum.
An active explosion protection system basically
consists of three components: One or more
explosion detectors, an electronic system
controller, and one or more protective devices
such as explosion suppressors or isolation
valves. Instrumentation wiring interconnects
these components.
The system controller is microprocessor-based
and shall be installed in a location that maintains
the EPC’s temperature rating of -18°C to 43°C
(0°F to 110°F) when it is installed in an auxiliary
housing. For FM Approved installations the
housing shall be a lockable enclosure
conforming to the installed area requirements as
defined by NEMA 250 “Enclosures for Electrical
Equipment (1000 Volts Maximum).”
Besides its function as a fire controller it also
incorporates an event table and a self-checking
feature to continuously monitor the complete
system-loop for errors or system defects.
Electronic devices, microprocessors,
pyrotechnic initiators, and field wiring are
influenced by the electromagnetic “environment”
surrounding these components. The use of
cellular telephones, transmitters, induction
motors, welding equipment or the presence of
power cables and transformers can create
environments with high levels of electromagnetic
radiation, resulting in induced electrical “noise”
or voltage peaks.
Such effects are known to designers and
manufacturers of instrumentation and control
systems (PLC’s), used in industrial
environments and are handled through the use
of specially designed electronic filters. These
filters neutralize the unwanted noise and offer a
“clean” signal for further processing. The filters,
however, result in a delay in the processing of
signals, and can therefore only be applied with
great care in explosion protection systems
where the effectiveness depends on the overall
response time.
In active explosion protection systems, a
balance must be maintained: The system must
be extremely fast to achieve the required
effectiveness, but at the same time must be
stable and insensitive to surrounding sources of
noise.
The system controller will detect and report
major system troubles (such as ground faults,
wire disconnection, and unstable input or output
signals) and indicates the need for appropriate
action.
The system controller will also detect
unacceptable levels of electromagnetically
induced noise. If the magnitude of the noise is
such that this may result in a risk for
spontaneous system activation or affect the
system’s performance, the controller will revert
to its default error-mode.
It is essential to practice extreme caution when
selecting component location, cable
specifications, cable routes, and the
“cleanliness” of the offered power source. In
order to reduce the electromagnetic induced
noise to a level that will not affect the required
performance of the explosion protection system,
verify all earth connections. It is preferred to
have the enclosure and conduits connected to
Protective Earth (similar with other building
grounds) while the drain wires from the field
wiring and each module ground connected to a
separate Instrument Earth. This Instrument
Earth connection shall not have inductive or
capacitive loading such as motors, welders, or
other industrial equipment. Where a separate
earth connection is not available, the drain wires
and module ground connections should be
made to battery common. Complying with the
following recommendations will help minimize
the induced noise to acceptable levels.
4.2 POWER SPECIFICATIONS
The AC supply (commonly supplied to the
EPACO Power Supply Unit, PSU) shall be wired
through a dedicated circuit to a
1002/120/240VAC 15 or 16 Amp circuit breaker.
High voltage circuits may NOT be run in the
same conduit as low voltage circuits.
Cabling from transformer to PSU shall be
1.3 mm2(16AWG) minimum not to exceed
3 meters (10 feet).
2Not FM Approved for 100 VAC.

FIKE CORPORATION
FM 3020541 Fike Explosion Protection System Page 5 of 20
P/N E06-054 Rev. 1 07/04
Cabling from PSU to RC8 shall be 0.8 mm2
(18AWG) minimum not to exceed 10 Ω
resistance.
A keyed selector switch is recommended in the
PSU to RC8 power supply cabling to facilitate
reset of the RC8. This shall have a 30V, 1A
rating.
4.3 RELAY CARD (RC8)
The Relay Card (RC8) is a DIN rail mounted,
fully programmable module containing eight (8)
Form “C” relays. Each relay is equipped with a
green LED to provide a visual indication of the
relay state. These relays facilitate process
shutdowns or other actions in response to
conditions recognized by the EPACOsystem.
The RC8 is powered with 24VDC from the PSU.
Up to four (4) RC8s can be connected in parallel
to the power supply. The RC8 is capable of
communicating on the Status Bus for
exchanging status information and remote
control of the outputs. A history of the relay
states is captured in the Annunciator Module.

from the EPACO PSU or an approved power
source for proper operation of the status bus.
4.4.2 Relay (P2 & P3)
Relays 1 through 8 are available to provide
EPACO system status to monitoring equipment.
The relays are a “fail-safe” relay that will transfer
upon any system upon the programmed
condition. This can be used for equipment
shutdown, visual, audible, or other type
annunciation. Trouble conditions may or may
not affect the protection system’s ability to
respond to a deflagration, but must be
acknowledged and identified prior to continuing
to run the process.

5.0 OPERATION
5.1 CONFIGURATION
The RC8 is a fully programmable module.
System configuration can be performed with
DIPswitches on these modules or by way of a
DB9 serial port connection to a PC using
EPWorks™ Software. RC8 addressing is done
using the two ADD (address) DIPswitches. The
four MODE DIP switches are used for
programming specific relay configurations.
Expanded programming may be created via PC
with Fike's EPWorks™ Software.
Exhibit 5-1 Serial Port
5.1.1 Dip Switch Configuration
The EPACO system can have multiple RC8’s
connected to a single system. The ADD
switches enable the system to distinguish
between multiple RC8’s. The RC8 is configured
to one of six (6) configurations using the MODE
DIP switches on the face of the unit. The
configuration of the DIP switches set the relay
operation parameters of the RC8. The DIP
switches incorporate a safety feature that
prevents a programming change should one of
the DIP switches inadvertently get changed.
5.1.2 PC Configurations
There are twelve (12) relay configurations that
can be selected using a PC with EPWorks™
software. These relay configurations are more
elaborate than are available with the DIP switch
configurations.
NOTE: Address and configuration changes
are to be made by Fike authorized
engineers or technicians only.

5.2 RC8 STATUS
The RC8 is a process interface for the EPACO
system. The following tasks are accomplished
by the RC8:
•Communicates system status via relays for
user interface
•Direct shut downs, slow downs, and remote
notifications of system trouble and alarm
conditions
•Remote location of interface, separate from
the hazard zone
The RC8 operation can be classified into two main states of operation: Normal and Trouble / Alarm. Each
of these states is described in sections 5.2.1 and 5.2.2. Exhibit 5-6 further describes other conditions within
these states in a handy spreadsheet for quick reference.
5.2.1 RC8 Normal State
When power is applied to the RC8, it performs a 15 second
initialization. At the end of the initialization, the Status Bus LED will
turn on and the appropriate relays and relay LEDs will be energized to
indicate the current status of the EPACO system.
5.2.2 RC8 Trouble or Alarm State
A trouble or alarm occurs on the EPACO system if any one of the
supervised circuits experiences a wiring fault open or short condition, if
a configuration is invalid, if the system is disabled, if a process
pressure warning level is exceeded, if the input voltage drops below
18VDC or the activation criteria on the detector inputs have been met.
In the Trouble or Alarm State the green LED programmed to respond
to the fault or alarm condition will turn off, and the corresponding relay
is de-energized. Depending on the cause of the trouble, the system
may or may NOT be completely functional. Each trouble should be
investigated to determine the cause and promptly fixed. Each trouble,
except for remote disable, will latch at the EPC. If the trouble is
resolved, the EPC trouble can be cleared by disabling and re-enabling
via the remote disable input, by cycling of the power input to the EPC,
or by disabling and re-enabling the EPC via the Annunciator Module
(see Annunciator Module Installation and Operation Instructions E06-
053). If the remote disable is active, the EPC will enter the trouble
state. When the remote disable is returned to normal, the EPC will
automatically clear to the normal state, if no other troubles are present,
without cycling the power.
Note: The alarm state will activate the system. If the system is
reset after an alarm, it is typical to have an open wiring fault on
the Series Firing circuit, since the actuator(s) have activated.

6.0 PERIODIC MAINTENANCE
CAUTION: If assistance is needed before performing any maintenance or service work on the Fike
Explosion Protection equipment and/or systems, contact Fike for instructions. See
section 11.0 Repair and Return Authorization for contact information.
6.1 GENERAL
Routine system inspections shall be conducted
in accordance with the requirements of the
appropriate local authority having jurisdiction
and National Fire Protection Association
Standard Number 69, Explosion Prevention
System, current edition.
The inspection schedule and procedure set forth
below are provided as a minimum requirement
for Fike Explosion Protection System
Controllers, which operate in moderate
environments. These control panel instructions
are to be implemented in conjunction with
complete system inspection instructions.
During initial system checkout or start-up, the
Fike Factory Field Personnel, due to process
operational characteristics and/or historical
inspection data on the specific process, may
determine that an additional inspection is
required. If this occurs, it will be in addition to
the following maintenance schedule.
It is extremely important to closely monitor the
operational characteristics of your system during
the first few days and weeks after the initial
start-up.
6.2 INSPECTION PROCEDURE
The following is the recommended procedure to
follow when conducting an inspection.
Step 1: Disable the Control Panel
Step 2: Shunt the GCA’s and install jumpers
Step 3: Re-Arm the Control Panel and Disable
Step 4: Calibrate the pressure detectors
Step 5: Cycle the Explosion Isolation Valves – if
present
Step 6: Checkout the panel
Step 7: Reconnect the GCA’s and log the
container pressures and serial numbers
Step 8: Re-arm the system
6.3 ROUTINE INSPECTIONS
These inspections are to be performed by Fike
Field Personnel or personnel trained and
certified by Fike.
To perform an inspection, it is important to first
obtain all pertinent data that relates to the
specific system being inspected. The required
information includes:
