LOCAL CONTROL UNIT (LCU)

The LCU functions as the heart ofthe system. It contains the firelogic for controlling the releasingand signaling outputs and also pro-vides operator interface controls(silence, acknowledge, reset, iso-late), annunciation relays, and a

local information display. The LON/SLC starts andends its loop at the LCU and two serial communica-tion ports allow configuration and system monitoring.An isolation module provides ground fault monitoringfor LON/SLC and serial port wiring.

The LCU consists of a three position rack that housesthe Communication Gateway, Logic Controller, and

Isolation Module. These three modules plug into theLCU backplane.

The Communication Gateway is usedin conjunction with Det-Tronics softwareto configure the system as well as toprovide information on an ongoing basisto external systems such as PLCs andDCSs. The gateway communicates

through two serial ports using Modbus RTU and/orAllen Bradley DF1 protocols. It also provides localdisplay and four programmable relay outputs. Inaddition, the gateway provides a heartbeat signal thatis used to test for LON/SLC integrity, to provide time

and date information to field devices, and to monitorfor the continued presence of all configured fielddevices.

The Logic Controller provides thecontrol function for the fire detectionportion of the system. It continuouslymonitors messages from the fielddevices on the loop and performs thelogic functions needed to generate theappropriate output(s).

The logic controller receives configuration information

from the gateway through its serial connection to theOperator Interface Station (OIS). It also communi-cates with the output modules located in the LocalOutput Unit or on the LON/SLC, controlling systemfunctions such as alarm signaling, agent release andrelay actuation.

The logic controller performs both fixed and user pro-grammable logic operations.

Fixed logic controls the faceplate displays and relayoutputs (alarm, trouble and supervisory) perANSI/NFPA 72. When the logic controller receives aFire Alarm message from a field device, fixed logicactivates built-in annunciation circuits, consisting ofboth visible and audible alarms.

Programmable logic allows the logic controller to becustomized to perform a variety of complex logic

operations. Using Det-Tronics EagleVision-NT soft-ware, the system can be programmed for nearly anyimaginable type of cross-zone monitoring, voting, andtimed operations that might be needed in a fire sup-pression system.

The Isolation Module (LON Isolator)protects the integrity of the LON/SLCwiring by isolating shorts and monitor-ing for ground faults. It also provideselectrical isolation for the two serialcommunication ports between thegateway and host devices.

LOCAL OUTPUT UNIT (LIOU)

The LIOU is part of the fire detec-tion portion of the Eagle Quantumsystem and performs functionssuch as fire suppression agentrelease and notification. The

LIOU consists of a card rack containing up to six out-put modules, mounted in a NEMA 4 enclosure.

The LIOU is controlled and supervised by the LCUusing an RS-485 serial communication link. Up tofour LIOUs can be controlled by the LCU, allowing upto 24 output modules in the system.

Available LIOU modules include a Relay Module, aRelease Module, and a Signal Audible Module. Amaximum of 8 modules of any one type can beinstalled in the system.

The Relay Module provides fourunsupervised relay outputs. Therelays are independently pro-grammable and can be used forcontrol of auxiliary functions such

as fan shutdown and damper control. Each relay hasSPDT contacts, rated 2 amperes at 24 vdc or 1ampere at 120 vac.

The Release Module provides sig-naling and agent release capabili-ty. Its supervised outputs includeone programmable release circuit

and three Style Y signaling circuits. The release cir-cuit is compatible with a variety of solenoid or initiatorbased suppression systems.

The Signal Audible Module pro-vides four indicating circuits forcontrolling UL Listed 24 vdc polar-ized audible/visual indicatingappliances. Each output circuit

delivers up to 2 amperes at 24 vdc and is indepen-dently programmable to allow annunciation of sepa-rate events.

Intelligent Field Devices on the LON/SLC

The LON/SLC is a fault tolerant, two wire, digital com-munication network, arranged in a loop that starts andends at the Local Control Unit. In its base configura-tion, the LON/SLC supports up to 60 intelligent fielddevices spread over a distance of up to 2000 meters(up to 244 field devices and 10,000 meters of wiringusing network extenders). Devices on the network

can consist of a combination of Flame Detectors,Initiating Device Circuits (IDCs), DigitalCommunication Units (DCUs), Agent ReleaseModules and Signal Audible Modules.

Alarm/Calibration LogEach network device maintains an alarm log in non-volatile memory, recording the time and date for thelast 8 alarms. In addition, the DCU keeps a calibra-tion log that can be used by the operator to evaluatethe remaining life of the sensor. This log includes thezero, span, date and time for each successful calibra-tion.

Fault Tolerant NetworkThe Eagle Quantum system utilizes a unique patentedtechnique for detecting problems in the networkwiring. This feature minimizes the possibility of a com-munication breakdown in the event of a wiring faultand can also serve as an aid in troubleshooting.

Each device on the LON/SLC contains both the hard-ware and software necessary to isolate and re-routecommunication in the event of a network wiring fault.When a problem occurs somewhere within the net-work wiring, the gateway annunciates the fault, whilethe fault isolation circuitry in the affected nodes iso-lates the section of the network where the fault hasoccurred. Communication is thereby ensured and willcontinue over the network. See Figure 2.

A single open or short on the LON/SLC will not affectsystem communication between the field devices andthe gateway. System communication will continueuntil the wiring problem can be repaired.

The EQ2100PSM Power SupplyMonitor and EQ2200IDCGFInitiating Device Circuit GroundFault module monitor the system

power supply and immediately report any detectedpower related trouble to the LCU.

The EQ2200UV UV FlameDetector is a unitized UV flame

detector, equipped with bothautomatic and manual opticalintegrity ( o i ) test capability. Whena fire is detected, a fire alarm

message is immediately sent to the Logic Controller.Detector status is indicated by red LEDs that are visi-ble through the detectors viewing window.

The detector is equipped with a special arc rejectionfeature that enables it to prevent nuisance fire alarmscaused by UV from short-duration electrical arcs orelectrostatic discharge, while maintaining the ability toreliably detect the UV given off by a flame. Typical

applications that benefit from arc rejection logicinclude electrostatic coating processes and uncon-trolled environments where transient UV sources canbe present, such as many typical outdoor applica-tions.

To enhance detector versatility, different levels of arcrejection, as well as sensitivity and time delay are fieldselectable.

The EQ2200UVHT High Temper-ature UV Flame Detector is ratedfor continuous duty high tempera-ture applications, such as turbinecompartments, enclosures, gener-ator rooms, etc. where ambient

temperatures can continuously exceed +75C(+167F), up to 125C (+257F).

It consists of an electronic module that is used with ahigh temperature rated UV detector. The two devicesare mounted in separate enclosures and can be sep-arated up to 165 feet (50 meters) using high tempera-ture rated shielded cable.

The EQ2200UVIR Flame Detectorprovides reliable fire protection inapplications where the use ofeither UV or IR detectors alone canresult in false alarms. The devicecombines both a UV and an IR

sensor in a single detector and requires simultaneousresponse of both sensors to generate a fire alarm.This enables it to respond to a real fire while ignoring

potential false alarm sources such as arc welding, x-rays, or hot vibrating objects.

The microprocessor based detector is equipped withadvanced fault detection and diagnostic capabilities.

A pair of red LEDs that are visible through the viewingwindow of the UV sensor provide a visual indication ofdetector status.

The detector offers software selectable options suchas variable sensitivity and time delay, standard or arcrejection mode, automatic or manual oi, and latching

fire output.

The EQ2200IDC Initiating DeviceCircuit (IDC) accepts two dry contactinputs for use with devices such asrelays, pushbuttons, key switches, etc.The IDC supports ANSI/NFPA 72 ClassB Style B supervised input circuits.When an input is activated, an alarm

message is immediately sent to the Logic Controller.

The EQ2200DCU Digital Communi-cation Unit (DCU) digitizes a 4 to 20ma analog signal and transmits thevalue as a process variable to theLCU.

The DCU is approved for use with avariety of Det-Tronics sensors including catalyticcombustible gas sensors, the PointWatch IR gasdetector, and the hydrogen sulfide (H 2 S) electro-chemical sensor. It will also accept any sensor with alinear 4 to 20 ma output signal and allows for one per-son non-intrusive calibration.

The EQ2500ARM Agent ReleaseModule (ARM) provides agent releasecapability to the Eagle Quantum sys-tem. The device is located on theLON/SLC and is controlled by pro-grammable logic in the LogicController. The release module is

designed to monitor and control two output circuits,which are energized together. It is compatible with avariety of solenoid or initiator based suppression sys-tems.

The release circuit is supervised for open circuit con-ditions. If an open circuit occurs, a trouble conditionwill be indicated.

The EQ2500SAM Signal AudibleModule (SAM) provides two indicatingcircuits for controlling UL Listed 24vdc polarized audible/visual indicatingappliances. Each output circuit isindependently programmable to allowannunciation of separate events. The

outputs operate in the reverse polarity fashion whenactivated. Each output delivers up to 2 amperes at24 vdc.

The Signal Audible Module is located on theLON/SLC and is controlled by programmable logic in

the Logic Controller. Each output circuit is super-vised for open and short circuit conditions. If a wiringfault occurs, a trouble condition will be indicated.

The EQ2400NE Network Extenderallows for expansion of the communi-cation network. The base systemcan accommodate up to 60 nodesand up to 2,000 meters of wiring. By

adding the appropriate number of network extenders,this can be increased to 244 network devices and upto 10,000 meters of wiring.
