Contains internal connections and supervision circuitry for secondary power source consisting of; 24VDC battery array available in 7, 12, or 24 amp hour ratings. 2.7 Master Module - One required per system and acts as the main processor that operates the front display, monitors the internal power supply and maintains bus communication with up to 29 Line Modules. Common system Alarm and Trouble outputs via dry form C contacts are provided. 2.8 Line Module - Bach Line Module provides four separate connection points for GreCon FM 1/8 and 3/8 spark detectors and four releasing circuits for connection to the GreCon solenoid extinguishing set. In addition, four outputs extinguishing circuits, one for each zone are provided. 2.9 RestrictedlLimited Access - In addition to the key-iocked enclosure restricting the user from access to the internal wiring, keypad access is only granted after execution of a proper password further restricting access to the user definable option. 2.10 FM 1/8, FM 3/8 Spark Detectors - Both detectors utilize the electrical circuits and enclosure as tested previously. New surface mount electronics are contained on a single circuit board. The single element FM 1/8 detector and the triple element FM3/8 differ in mounting techniques and application, but otherwise utilize the same circuitry. The FM 3/8 has provisions for connection to high temperature fiber optic polyps allowing the detector to mount remotely from the high temp application. 2.11 KK 9/1 Junction Box - This new version termination (junction) box utilizes the identical enclosure as tested previously. It provides three separate input circuits for connection of drycontact input devices. III EXAMINATIONS AND TESTS 3.1 One sample each of the CC 7004, 7020, 7036 console as well as samples of the FM 1/8 and FM 3/8 detectors and KK 1/9 junction box has been and examined at FM Approvals in Norwood, MA. These samples, considered to be representative of the product line and included as a minimum, one sample of each plug-in module with additional optional modules used to complete the enclosure at its maximum capacity. The equipment as supplied and tested was compared to the manufacturer's documentation and drawings. All data is on file at FM Approvals along with other documents and correspondence applicable to this program. 3.2 Normal Operation - The Model CC7000 spark extinguishing alarm control was tested to verify proper operation under normal conditions. The system performed as described below and in the Installation, Operation and Instruction Manual. A normal condition is indicated by the illumination of the green "Operation" and "AC Mains" indicator lamps. 3.3 Trouble Signals - Trouble signals and their restoration to normal shall be indicated within 200 seconds. A switch for silencing the audible trouble signal is permitted only if it transfers the trouble indication to a lamp or other acceptable visible indicator adjacent to the switch. The visual indication shall persist until the trouble has been corrected. It was verified that the audible trouble signal sounds if the switch is placed in the "silence" position and no trouble exists. 3.3.1 Fault conditions (single open, single ground, and wire to wire shorts) were introduced on extemal circuits. The trouble signal was annunciated audibly at the control and visually by the Page 4 af 11

illumination of the yellow "Trouble" LED with the individual problem identified on the alphanumeric display. Both audible and visual indications remained until the trouble condition was corrected. 3.3.2 It was verified that the manual means for de-activating the "Trouble" signal resides behind a keylocked door. This is satisfactory. 3.4 Alarm Signals - Alarm signals and their restoration to normal shall be annunciated within 10 seconds and produce a distinctive signal. A switch for silencing the alarm signal sounding appliances shall be permitted only if it is key operated or located within a locked cabinet. Such a switch shall be permitted only if it transfers the alarm indication to a lamp or other acceptable visual indicator, and subsequent alarms in other zones will operate the alarm signal sounding devices. 3.4.1 Alarm conditions were introduced on the initiating device circuits. The alarm signal was annunciated audibly and visually indicated on the control by the flashing or intermittent illumination of the red "Alarm" LED. Additional text appeared on the alpha numeric display indicating the affected zone and type of device as well as the operation of output circuits as required. 3.4.2 It was verified that the manual means for de-activating the "Alarm" signaloperated properly silencing the local audible and notification appliance circuits, provided a visual indication land resided behind a key-iocked door. 3.4.3 It was verified that subsequent alarm signals from different zones were properly displayed and caused re-activation of the notification appliance circuits. 3.5 Environmental Tests - Samples of the BS 7000 system were conditioned at the foliowing temperature extremes as described below: 3.5.1 cc7004 Control Console - 16 hours at -10 C (14 F) and 40 C (104 F) and 24 hours at 38 C (100 F) with 90% relative humidity. 3.5.2 FM 1/8 and FM 3/8 Spark Detectors and KK 9/1 Junction Box - 16 hours at -40 C (-40 F) and 70 C (160 F) and 24 hours at 38 C (100 F) with 90% relative humidity. 3.5.3 Proper operation was observed both during and after eachof these environmental exposures. 3.6 Voltage Variation Tests - The input power was varied from 85% to 110% ofrated voltage (102 to 132Vac primary and 20.4 to 26.4Vdc secondary) to the control console. The control and connected peripherals operated as intended overthese entire voltage ranges. This is acceptable. 3.7 Circuit Performance - The initiating device circuits, the notification appliance circuits, and the releasing circuits were tested to verify that they met the intent of the appropriate performance requirements as described in ANSIINFPA 72-2002 National Fire Alarm Code. Open, ground, wire to wire short, combination open and ground faults were introduced through the appropriate circuit. 3.7.1 lnitiating Device Circuits - The 3-wire spark detector initiating device circuits of the cc70xx control console, KK1/8 and KK9/1 junction box were verified to meet the intent of Class B (Style A) operation as defined by Table 6.5 ofnfpa72-2002. Page 5 af 11

3.7.2 Notification Appliance Circuits - It was verified that the output circuits of the cc70xx are nonsupervised and therefore must be located within the same room of origin as the cc70xx console. This is satisfactory since the primary purpose of this control is process protection and not that of an evacuation unit. 3.7.3 Releasing Circuit - It was verified that the release circuits of the cc70xx were properly supervised for open, short and single ground fault conditions. 3.8 Secondary Power Supply Test - The secondary (standby) power supply shall automatically supply the energy to the system within 10 seconds, and without loss of signals, whenever the primary supply is incapable of providing the minimum voltage required for proper operation. 3.8.1 Transfer to the secondary power supply was accomplished automatically and in less than 10 seconds upon loss of primary power to the control. The loss of primary Ae power was indicated within 60 seconds by the illumination of the yellow "Trouble" LED and illumination of the "Mains" LED and the sounding of the local audible annunciator. 3.8.2 The transfer to secondary power was observed at 85V ac. The equipment continued to operate properly down to the transfer point and after transfer while on secondary power. 3.8.3 It was verified that secondary power is properly supervised from accidental disconnect (line break) and operationlfailure of the battery charger circuit protection fuse (FBat). 3.8.4 It was verified that return to primary power occurred at approximately 102V ac and the "Trouble" cleared automatically (non-latching) 3.9 Battery Discharge and Recharge Test - After a fully charged battery is subjected to a single discharge cycle (4 hours standby and 10 minutes in full alarm load), the charging current shall be such that after 48 hours, the battery is retumed to a fully charged condition. 3.9.1 The two 12 V dc 24AH batteries were charged for more than 48 hours and the battery voltage was observed to be 27.2 V dc, and the charging current was observed to be 0.010 A. 3.9.2 The power supply was configured to draw 2.9 A (the maximum standby load specified by the manufacturer), and the primary power supply was disconnected. The battery voltage decreased to 23 V dc after 4 hours of discharge. A 10 minute Alarm load of 6.0 A was then applied to the control. All output circuits remained above 20 V dc. 3.9.3 The primary power was then reconnected, and the initial charging current was <1.0 A. The batteries were allowed to charge for 48 hours. At the end of 48 hours, the trickle current was measured to be 0.020 A, and the float voltage of the batteries was measured at 27.2 V dc, which indicated a fully recharged battery. 3.10 Electrical Safety Tests 3.10.1 Protective Grounding - Accessibie conductive parts of the equipment that are likely to become energized in the event of a fault shall be properly grounded. A suitably sized and properly labeled ground connection is provided in the control panel. The resistance from all surfaces likely to be energized was measured to the ground connector. The maximum resistance was less than one ohm in all cases. Page 6 af 11

3.10.2 Eleetrieal Shoek - Examination showed that accessibility to the 120 VI 240 V ac power supply was suitably restricted by the locked steel cabinet. 3.10.3 Nameplate Rating - With the maximum loading on the power supply, the input load drawn must not exceed 110% of the marked input load rating of loa at 120 Vac. Testing showed that the maximum input load was 5A at 132 Vac with a full 18 load on the power supply, which is acceptable. 3.10.4 Dieleetrie Test - A test voltage of 1,240 Vac was applied for one minute between the power terminals and system ground. There was no dielectric breakdown observed during this test. 3.10.5 Battery Cireuit Reverse Polarization - The battery system was observed as using polarized connectors would not allow for miss-connection during installation. As aresult, this test was waived with satisfactory results. 3.11 Vibration Test - ane sample of the AKKUTEC 2402 was mounted in it's normal position and subjected to a four-hour vibration test of 0.02 inches (0.5 mm) displacement at a frequency sweep of 10 to 30 Hz. The equipment operated properly during and after this vibration test, and there was no loosening of parts or permanent deformation as aresult of this test. 3.12 Radio Fregneney Interferenee (RFI) - Although not an Approval requirement, the foliowing test was performed on the Model cc7004 controls with the FM 1/8 and 3/8 detectors connected: The powered control was subjected to voice modulated and un-modulated radio signals having frequencies of 154 MHz, 467 MHz, and 854 MHz with radiation power levels equivalent to 5.0 Watts from a distance of 0.61 m (24 in.). The controls did not false alarm or display any signs of instability as aresult of this test. IV MARKING 4.1 The foliowing information appears on the equipment identified in Section 1.7 and meets Standard requirements: Manufacturer's name and manufacturing location. Serial number and date code (on separate adhesive label) Maximum electrical input and output ratings The FM Approval Mark 4.2 The software/frrmware version (1.4) and ~erial number are displayed on the Alpha-numeric display by accessing the "System Info" level via the password protected keypad. Refer to Installations Manual for more information. V REMARKS 5.1 Extreme care should be taken with the installation of this equipment. The latest edition of the manufacturer's instruction manual must be followed completely, and any problems should be resolved by consultation with the factory or the authorized representative. 5.2 All installation wiring shall be in accordance with the appropriate national electrical code. (ANSIINFPA 70). Page 7 af 11

5.3 An Approval examination of programmable equipment such as this can only evaluate typical configurations. Although those components identified in this report have been tested, it is beyond the scope of such an examination to test all possibie configurations. It is necessary, therefore, that those responsibie for the setup and acceptance of specific installations take special care to verify that the equipment, including programmable functions, is configured to operate properly for the required performance of that installation. 5.4 Because of the extreme sensitivity of the.spark detectors and their response to visible light, installation in a totally dark environment is required. 5.5 A weekly test procedure should be established, which includes an individual check of each detector using a portable light source (such as a flashlight) foliowing the manufacturers recommendation to verify proper operation. A complete maintenance schedule for testing and cleaning the lens of each detector should be foliowed. 5.6 The automatic test feature of the BS 7000 system should be employed, but by itself it can not be considered as a replacement for periodic visual inspections and cleaning as required. 5.7 The system is intended to protect a specific hazard: sparks or embers in the duct system. It should not be considered a substitute for general fire protection apparatus, including appropriate sprinkler protection. 5.8 Systems should not be used where an extreme change in temperature or humidity are anticipated which couldresult in condensation on the lens ofthe detector. 5.9 The adequacy of the water supply must be assured for effective operation of the system. Valves controiling the system supply should be adequately protected against improper closing and precautions should be taken to maintain the temperature of the water supply lines and valves above the freezing point. 5.10 This BS 7000 system is an alarm system designed to protect a particular hazard and can not be used as a protected premises fire alarm system intended for building evacuation unit as defined in NFPA 72, The National Fire Alarm Code. However, it does provide dry Form "C" Alarm and Trouble contacts that may interface with a variety of Approved local alarm signaling systems. 5.11 When disconnecting the extinguishing system discharge for testing and/or maintenance, the extinguishing system must be isolated mechanically and not solely by electrically disconnecting the equipment and not by the software programming. VI FACILITIES AND PROCEDURES AUDIT The manufacturing site in AlfeldIHannover Germany is currently included in the FM Approvals Facilities and Procedures Audit (F&PA) program. The facilities and quality control procedures in place have been found to be satisfactory to manufacture product identical to that examined and tested as described in this report. VII MANUFACTURERS RESPONSIBILITIES 7.1 The manufacturer shall provide instructions for installation, operation, and maintenance with each unit. Page 8 af 11

7.2 As part of the listing requirements, FM Approvals requires assurance that subsequent systems produced will present the same quality and reliability as the system examined. The manufacturer shall maintain a Quality Assurance Program, which includes as a minimum: incoming, inprocess, and final inspection and testing; equipment calibration, and drawing change control. The specific procedures used to control quality are best determined by the manufacturer. 7.3 Documentation considered critical to this Approval is on file at FM Approvals and listed in the Documentation File, Section VIII of this report. No changes of any nature shall be implemented unless notice of the proposed change has been given and written authorization obtained from FM Approvals. The Approved Product Revision Report, Form 797, shall be forwarded to FM Approvals as notice of proposed changes. 7.4 Since the power supply (UPS) is rated above 30 Vrms, it is required that the final assembly of all ARC-l controls be dielectric tested on 100% of production. The power input connections shall withstand, for one minute and with no insulation breakdown, the application of 1000 V ac (or 1400 V dc) with respect to the protective ground. Altematively, a test potential of 1200 V ac (or 1700 V dc) may be applied for at least one second. WARNING: The dielectric test required may present a hazard of injury to personnel and/or property and should only be performed under controlled conditions, and by persons knowledgeable of the potential hazards of such testing to minimize the likelihood of shock and/or fire. 7.5 Each fully assembled control console (cc70xx) shall be tested for continuity of the protective grounding system on 100% of all production.
