1.0 Introduction
Mircom’s FR-320 Series Pre-Action/Deluge and Agent Release Control Panel performs the
function of fire suppression in a wide variety of applications. It is capable of being used in an
agent release sprinkler system or in a pre-action or deluge sprinkler system. It can be used in
single-hazard or dual-hazard applications with or without cross-zoning. The panel includes
common alarm, supervisory, and trouble relays, and provides regulated and unregulated
auxiliary power along with four-wire smoke power. It supports auxiliary relays. The auxiliary
relays are based on a hazard area status. The FR-320 Series has six input zones and four
output zones, allowing for flexibility in most single and dual-hazard applications for both
deluge and agent releasing applications.
1.1 Panel Type
The panel can function as an agent release panel or as a pre-action/deluge panel, depending
on which of the available fixed configurations are chosen from the main programming menu.
1.1.1 Deluge sprinkler system
In deluge sprinkler systems open-valve sprinkler heads terminate to a water supply that is
controlled by a single valve. When the system detects fire, it automatically opens the valve via
a releasing circuit, allowing the water to flow through all the sprinkler heads. Deluge sprinkler
systems are useful for applications in which simultaneous discharge of water through every
sprinkler is required.
1.1.2 Pre-action sprinkler system
In a pre-action sprinkler system close-valve sprinkler heads are connected to pipes that are
supervised for air pressure. The pipes terminate directly to a water supply. Pre-action systems
are useful for applications in which the prevention of an accidental discharge of water is
required.
1.1.3 Agent release system
In an agent release system, an extinguishing agent (such as Argon, dry chemical, CO2, Halon,
etc.) is automatically released upon fire detection. An abort function is added to prevent the
false release of the extinguishing agent.
1.2 Overall Features
•6 class B Initiating Device Circuits, which may be configured as class A using input class
A converter adder modules. Each Initiating Device Circuit is pre-configured as Alarm,
Supervisory (Latching or non-latching), water-flow, Manual Release Switch, or Abort
Switch. There are two LEDs per circuit, one for Trouble (amber), and one dual color
(amber/red) LED for Supervisory (amber) and Alarm (red).
•4 power limited class B output circuits. Output circuits 1 & 2 are Notification Appliance
Circuits while output circuits 3 & 4 are releasing circuits (circuit 4 can work as a
Notification Appliance Circuit in some situations; check Pre-Programmed Modes on
page 62 for details). Each Notification Appliance Circuit process type is pre-configured
and can be silenceable. The signal rates depend on the selected pre-programmed
configuration.
•A pushbutton associated with each Initiating Device Circuit and Notification Appliance
Circuit can individually disconnect (bypass) the circuit.
•Configurable Signal Silence Inhibit and Auto Signal Silence Timers.

•Subsequent Alarm, Supervisory, and Trouble operation.
•Non-resettable auxiliary power supply, 300mA max.
•Four wire resettable smoke power supply, 100mA max.
•Relay Contacts for Common Alarm, Common Supervisory, Common Trouble, and
Auxiliary Alarm Relay (disconnectable).
•RS-485 Interface for RA-1000 Series Remote Multiplex Annunciators and Smart relay
Module.
•Optional Modules for additional Relay Circuits.
•Extensive transient protection.
•Easy configuration of the panel using LCD service tool (CFG-300).
•Releasing circuit protection from false alarm by disconnecting the battery if the voltage
falls below 20.4V at the last releasing device.
•Wide range of compatible solenoids (see Appendix A: Compatible Solenoids).
•14 pre-programmed modes.

2.0 Conventions
2.1 Circuits
Refers to an actual electrical interface for initiating (detection), Notification Appliance Circuits
(signal), and releasing.
2.2 Zone
Is a logical concept for a Fire Alarm Protected Area, and will consist of at least one Circuit.
Often the terms Zone and Circuit are used interchangeably, but in this Manual the term Circuit
is used.
2.3 Display Points
There is a display point associated with every Initiating Device Circuit and Notification
Appliance Circuit of the FR-320 Series fire panel. For an Initiating Device Circuit there are two
LEDs for every display point: one single color (amber) and one dual color (red/amber). For a
Notification Appliance Circuit there is only one LED: one single color (amber), for every display
point.
2.4 Wiring Classes
Initiating Device Circuits and Notification Appliance Circuits are class B. Changing the
Initiating Device Circuits to class A requires an ICAC-306 adder board which will convert SIX
initiating zones from class B circuits to class A. This is done without penalizing the number of
circuits, which remains the same as in class B. Changing the Notification Appliance Circuits to
class A requires an OCAC-302 adder board, which will convert TWO indicating zones from
class B circuits to class A. Releasing circuits are class B only.

3.0 System Components
3.1 Main Pre-Action/Deluge and Agent Release Control Panel
The following models are part of the FR-320 Series:
•FR-320
•FR-320-W
•FR-320-R
Figure 1 FR-320 Series panel
All FR-320 Series panels have the following features:
•Six Zone Pre-Action/Deluge and Agent Release Control Panel with LED display (red or
white door, black box
•Six class B Initiating Device Circuits, and four class B output circuits
•Output circuits 1 & 2 are class B Notification Appliance Circuits that can be converted to
class A using an OCAC-302 Output Class A Converter adder module.
•Output circuits 3 & 4 are class B only releasing circuits.
•Each output circuit can supply up to 1.7A of current, 5A total. A six zone ICAC-306
Input Class A Converter adder module may be used for class A wiring of Initiating
Device Circuits.
•The FR-320 Series contains Common Alarm, Common Supervisory & Common Trouble
relays, auxiliary alarm relay (disconnectable), an RS-485 interface for remote
annunciators, non-resettable auxiliary power, and a resettable four wire smoke detector
power supply.
•Two batteries are required.
Additionally:
•FR-320 uses a BBX-1024DS or BBX-1024DSR enclosure.

fixed here) to the Main Fire Alarm Board.
Initiating Device Circuits must be wired from the ICAC-306 module to the Main Fire Alarm
board. For example, Initiating Device Circuit 1 positive (red) and negative (black) wires are
connected to the positive and negative terminals (respectively) of Initiating Device Circuit 1 on
the Main Fire Alarm Board. From the ICAC-306 converter Initiating Device Circuits are wired
out to the devices from the positive and negative terminals marked DET OUT and the circuit
return wires are brought back to the converter module to positive and negative terminals
marked DET RET.
5.3 OCAC-302 Output Class A Converter Adder Module
•
Figure 9 OCAC-302 output class A converter adder module
Notification Appliance Circuits must be wired from the OCAC-302 to the main Fire Alarm
board. For example Notification Appliance Circuit 1 positive (red wire) and negative (black
wire) is wired from the class A converter module to the positive and negative terminals of
Notification Appliance Circuit 1 on the Main Fire Alarm board.
The actual indicating zone is wired from the SIGNAL OUT positive and negative to the
signaling devices and then wired back to the SIGNAL RET positive and negative.
5.4 RM-306 Relay Adder Module
Cable from P1 of the RM-306 is connected to P4 on the Main Fire Alarm Board. The jumpers
located above each relay on the RM-306 are used to configure the relays. The jumpers
located below the relays are used to select either normally open contacts or normally closed
contacts.
