2.0 EPACO™ SYSTEM OVERVIEW
The EPACOexplosion detection and control system is comprised of explosion detectors, control unit (EPC),
power supply unit (PSU), optional annunciator module (AM) and relay cards (RC8). EPACOcombines 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. 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.
EPACOis designed to detect and control any of Fike’s Active explosion suppression and isolation systems;
which range from chemical suppression, mechanical isolation (gate and pinch valve), chemical isolation or
any combination thereof. Detection is achieved by either pressure and/or flame radiation detectors designed
to sense the incipient explosion and trigger the explosion suppression and/or isolation systems.

2.1 EXPLOSION PROTECTION CONTROLLER
The Explosion Protection Controller (EPC) is the cornerstone of
the EPACOsystem. The EPC is an addressable panel that has
the ability to retain an event history for enhanced system
diagnostics. The EPC is DIN rail mounted which allows mounting
of the controller 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 devices. 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. 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
perform complex programming by PC.
The following tasks are accomplished by the EPC:
Monitors all supervised circuits for wiring faults (Open, Short, or Activation)
Two detection circuits are monitored on a 250 micro second (0.25 msec) rate and examined for rate
of rise and threshold levels
When activation requirements are met by the detection circuit, it activates the series firing output
within 2 milli-seconds
Communicates system status to other EPC’s connected locally so that they can respond within 4 milli-
seconds
Communicates system status to Annunciators and Relay Control Modules for user interface

2.1.1 OPERATION
The EPC is equipped with three (3) colored LEDs that provide instant visual indication of system status. EPC
operation can be classified into three main states: Normal, Trouble and Alarm. A general description of each
state is described below.
EPC Normal State
When power is applied to the EPC, it performs a 4 second initialization. At the
end of the initialization, the trouble LED blinks slow and the local piezo beeps in
long recurring sound. It can then enter the “NORMAL” state if the power is of an
appropriate voltage and there are no troubles or alarms. In the Normal State the
green Power LED is ‘ON’, the local piezo is ‘OFF’, the trouble and alarm relays
are energized. All other LED’s are ‘OFF’.
EPC Trouble State
A trouble occurs on the EPC if any one of the supervised circuits experiences a
wiring fault open or short condition, if the EPC configuration is invalid, if the
system is disabled, if a process pressure warning level is exceeded, or if the input
voltage drops below 18VDC. In the Trouble State the yellow Trouble LED is ‘ON’,
the local piezo is ‘ON’, and the P6 trouble 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. 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.
EPC Alarm State
When the detection circuits have exceeded the alarm conditions required by the
configuration, the EPC enters the Alarm State. In the Alarm State the red Alarm
LED is ‘ON’, the local piezo ‘ON’, the Alarm relay is de-energized, and the series
firing output is activated. The alarm state is latching. If the alarm is cleared, the
EPC requires cycling of the power input to clear the alarm.
