Debris accumulated in air sampling pipe network during installation and assembly shall be removed by negative airflow prior to connection to the ASSD apparatus. Capillary Sampling Network: In areas with an accessible ceiling the sampling pipe network shall be installed above the ceiling with remote sampling points extending through the accessible ceiling using appropriate lengths of 0.375 inch (10mm) inside diameter capillary tubing attached to remote sampling points. Remote sampling point locations shall align in center of acoustical ceiling tiles where possible provided spacing meets the requirements of this Specification. Appearance shall be uniform in terms of sampling point row alignment. Coordinate layout with T-Bar grid. The maximum length of the capillary tube shall be 26ft (8m). An additional 2ft (60cm) of capillary tubing shall be provided for each drop to permit future relocation of remote sampling points (not to exceed 26ft (8m) limitation). Remote sampling points shall be labeled with the Manufacturers standard identification marking. Capillary tube and attachment to sampling pipe network shall be that required by the Manufacturer. Combined Detection Coverage: It is permissible for an air sampling pipe network to protect adjacencies provided a branched or separate air sampling pipe networks are deployed, sensitivity objectives and ambient background levels are equal, and that the ASSD apparatus exhaust is in an equal or negative pressure, not to exceed 100 Pascals (0.4 inches of water), in relationship to where sampling points are located. Strict compliance with the Manufacturers system design manual shall be given when applying a system in this fashion. ELECTRICAL POWER AND WIRING General: All power and distribution shall meet the requirements of the Manufacturer, applicable codes and standards. IDENTIFICATION Install framed instructions in a location visible from each ASSD apparatus. Identification shall include corresponding detector zone number, associated power supply number. ASSD apparatus identification to be consistent with BAS identification. This requires coordination between ASSD system contractor and BAS contractor. Initial commissioning settings Initial Commissioning Settings for ASSD Apparatus. Alarm threshold settings for air sampling smoke detection apparatuses shall be configured to achieve target port sensitivities above recorded average ambient peak level of 0.20% obs/ft for Alert, 0.6% obs/ft for Action, 1.0% obs/ft for Fire 1, and 2.5% obs/ft for Fire 2. Data review and analysis shall consider the normal base line or ambient pollutant level recorded, as well as all deviations from the established base line as recorded by the apparatuses event log. The recorded data shall then be used in conjunction with the following formulas to calculate alarm thresholds: Fire 2 Divide target sampling port sensitivity of 2.5% obs/ft by number of holes in overall system pipe network then add the recorded average ambient peak level to derive at the Fire 2 alarm threshold. Fire 1 Divide target sampling port sensitivity of 1% obs/ft by number of holes in overall system pipe network then add the recorded average ambient peak level to derive at the Fire 1 alarm threshold. Action Divide target sampling port sensitivity of 0.60% obs/ft by number of holes in overall system pipe network then add the recorded average ambient peak level to derive at the Action threshold. Alert Divide target sampling port sensitivity of 0.20% obs/ft by number of holes in overall system pipe network then add the recorded average ambient peak level to derive at the Alert threshold. Air sampling detection apparatuses which permit scheduling of sensitivity thresholds by date and/or time shall be programmed to use the same sensitivity thresholds specified herein 24 hours a day, 7 days a week. Time delays are intended to mitigate nuisance signals as a result of transient conditions. The following time delays shall be programmed into each detector apparatus: Fire 2: 30 seconds. Fire 1: 15 seconds. Action: 30 seconds. Alert: 30 seconds. Airflow fault delay: 60 seconds. Scan Delay (four zone air sampling detector apparatuses): 3 seconds. Sector Delay (four zone air sampling detector apparatuses): 15 seconds. Filter Fault: 1825 days. Signals REVISE SUBPARAGRAPHS BELOW TO MEET PROJECT REQUIREMENTS.

The ASSD system Contractor shall draft and submit, to the Architect / Engineer and the Owners Representative, for approval, a detailed Method of Procedure (MOP) commissioning plan, per area, which outlines all commissioning activities and identifies each activity and test, zone specific, necessary for a complete verification of the design and operation prior to start of testing. ADJUST DURATION BELOW TO MEET PROJECT REQUIREMENTS. The complete system shall be functionally tested in the presence of Architect / Engineer and/or Owners Representative and all functions must be operational at least [five (5)] days prior to the final acceptance tests. Tests and Inspections: General testing: All system and equipment devices shall function as required and designed. Each detector unit circuit shall be tested for trouble by inducing a trouble condition into the system. Test wiring runs for continuity, short circuits, and grounds before system is energized. Test and record resistance, current, and voltage readings as work progresses. Field tests shall be performed for all devices and functions of the ASSD system (100%) prior to the performing a final test to be witnessed and accepted by the local AHJ. All testing shall be coordinated with the Architect / Engineer and the Owners Representative Visual Inspection: Conduct visual inspection prior to testing. Correct malfunctioning equipment, and then retest to demonstrate compliance. Replace equipment that cannot be corrected or does not perform as specified and indicated, then retest to demonstrate compliance. Repeat procedure until satisfactory results are obtained. Report test results promptly and in writing to Architect / Engineer, the Owners Representative and Authorities Having Jurisdiction. Acceptance Tests: Prior to final acceptance, the installing contractor shall provide complete operation and maintenance instruction manuals as indicated in this Specification Part 1, Closeout Submittals and Documents. All aspects of system operation and maintenance shall be detailed, including piping isometrics, wiring diagrams of all circuits, a written description of the system design, sequence of operation and drawing(s) illustrating control logic and equipment used in the system. Checklists and procedures for emergency situations, troubleshooting techniques, maintenance operations and procedures shall be included in the manual. Final Acceptance Test shall begin only when the Preliminary Test Report has been approved. As-Built Drawings and previous test results shall be available at the time of testing. The installation shall not be considered accepted until identified discrepancies have been corrected and test documentation is properly completed and received. Prepare test and inspection reports. Upon completion of a successful test, the ASSD system Contractor shall so certify the system in writing to Owners Representative. Submit copy of test results in duplicate, after signed off by the AHJ, to the Architect / Engineer and the Owners Representative. Upon acceptance by the Architect / Engineer and the Owners Representative, the completed system(s) shall be placed into service. DEMONSTRATION AND training Train Owner's maintenance personnel to adjust, operate, and maintain ASSD systems. Prior to final acceptance, the installing contractor shall provide operational training to each shift of Owners personnel. Each training session shall include ASSD system operation, trouble procedures, supervisory procedures, auxiliary functions and emergency procedures. ADJUST DURATION BELOW TO MEET PROJECT REQUIREMENTS. Furnish training for a minimum of [four (4)] Owner designated employees of the system user: Training in the receipt, handling, and acknowledgement of alarms. Training in the system operation including manual control of output functions from the system.
