Repair Fire Alarm System Bldg 43
Presently the fire alarm system in building 43 consists of a Pyrotronics MXL-IQ Main Fire Alarm Control Panel (MFACP) which communicates and/or controls a number of other devices in the building as described in the following. The MFACP monitors various heat and smoke detectors throughout the facility which are part of the building’s “general fire alarm monitoring and alerting system”. Also, it monitors the activity of three (3) other MXL-IQ panels and one Fenwal 2320 panel; all of which act as Chemical Control Panels (CCPx) where “x” designates a number (1-4) of the Halon System being controlled. These CCP’s monitor a network of under floor smoke detectors and in turn initiate appropriate action to alert occupants and abort or release various Halon bottles into the appropriate areas. The building was constructed in three phases, a North (older) section, a South (newer) section and a new addition at the far north end of the previously mentioned facilities. The North section is equipped with a preaction type fire suppression system as well as a under floor Halon system. The Halon system in this part of the building is controlled by the Fenwal CCP. The South end of the building has a standard wet pipe system along with under floor Halon systems. The Halon systems in this part of the building are controlled by three (3) Pyrotronics MXL-IQ CCP’s. The new addition has an Edwards system which also reports to the MFACP. There are also other various independent systems in several parts of the main facility which report to the MFACP Currently the system is experiencing periods of unpredictable and undesirable operation. The most frequent type of reported problems is that a trouble signal will present itself at the MFACP with a particular code, the system can then be reset and either the original presentation will go away, reoccur or be replaced with an entirely different condition. Our technicians can only go to a certain level of troubleshooting; this has not produced any type of satisfactory solution to the chronic problems being presented. The purpose of this scope of work is to define a set of tasks to secure the services of factory certified technicians to perform a comprehensive and complete survey and evaluation of the part of the system as noted on accompanying drawings. This shall include all control panels, software operation, component operational status, perform minor repairs as described elsewhere in this scope, provide the government with a comprehensive report on the system’s condition.
The work shall consist of visual inspection of each component part in the parts of the system which are highlighted on the accompanying drawing, this includes but is not limited to all sensing devices, all alerting devices, all control and controlled devices and actuators, and shall also include minor cleaning in the case of detectors, and an operational check of each device to assure it is operating and reporting to the pertinent control panel in the appropriate manner. General testing and identification of the various wiring loops serving any part or all of the affected areas. A comprehensive diagnostic check of all control panels and intelligent modules in the system to verify software and hardware operation are correct and responding to all devices in the system in the required manner. The work shall include any necessary reprogramming, reloading of any existing system software that is noted to be problematic and any upgrades to the operating software that have become available since its original commissioning. If any components are found inoperable or are for any reason in need of replacement to restore full operation of the system, the contractor shall note these in his report and if possible at the completion of his inspection, render such defective devices inert by performing patches to the software at the main control panel which will allow the rest of the system to function normally. Since the system operates on the basis of poling devices using a serial data stream, testing for stray voltage or current shall be performed with test equipment capable of displaying various pulse wave-shapes such that data streams can be clearly differentiated from other underlying standing waves or stray voltages on a given sensing loop. Upon completion of the initial inspection and minor repair the contractor shall author a comprehensive report as outlined in the section labeled “REPORT”. This report shall be given to the government in both paper and electronic format using common programs such as Microsoft Word and Microsoft Excel.
REPORT: Federal Construction Group, Inc. shall deliver to the government a comprehensive report on the system which outlines the systems overall condition, recommendations for any necessary repair/replacement along with cost estimates for accomplishing any recommended repair/replacement. The report shall reference contract number and name, it shall have a general narrative section outlining the contractors observations formed as a result of the work/inspections performed, a section which details each abnormal condition found during the work along with any corrective action performed or needing to be completed to render the system fully functional. The detailed list of items needing repair/replacement should be presented in spreadsheet format. The contractor shall allow for an exit interview with the Project Engineer and the Station Alarm Technicians the purpose of which will be to summarize all work done, work needing to be completed and allow for the Government’s representatives to ask questions pertinent to the system and work performed.
