Edwards Field Notes Bulletin 13029E E-FSA Possible Nuisance Conditions With E-PD and E-PHD Detectors

Notes Bulletin E C H N I C A L S U P P O R T N 1 3 0 2 9 E Possible Nuisance Conditions E PD and E PHD Detectors technical bulletin details a nuisance condition that may exist with E PD or detectors and E PHD detectors manufactured between December 2009 and July may cause nuisance alarm conditions as a result of a combination of overly long term smoldering alarm limits and high background readings taken normal sensing operations high readings cause a reduction in the detectors maintenance range which be consumed quickly during operation On devices where the smoldering limit is too sensitive and the background reading is high the device may a nuisance alarm condition condition does not impact the detectors ability to sense normal alarm only a small number of customers have reported this condition we updating these devices on site using the SIGA MFT tool and a utility created If you do not have a SIGA MFT tool contact Technical Support to obtain 13029E ISS 15JAN14 5 detectors should be updated using the TF13029 utility as soon as to prevent further nuisance alarm conditions resulting from a of overly sensitive long term smoldering alarm limits and high readings taken during normal sensing operations This utility is not to address other known causes of nuisance alarms such as insect or transient smoke facilitate updating affected detectors we created a software utility that uses SIGA MFT to communicate with the devices and modify the long term alarm limit to the value currently being used in factory production utility generates a report Figure 3 for each loop that provides the total of devices that were updated If the utility identifies a device that it is not to modify the report indicates that the device can be returned for under warranty using the RMA process download the utility Go to www edwards signals com and copy the file TF 13029 zip to your Unzip the file and run the installer After successful installation of the utility the Name Setup dialog displays Figure 1 You may need to run the installer as Administrator Ask your IT for assistance in running the installer if you experience any 1 Name Setup dialog The following procedure requires the SIGA MFT tool Refer to the provided with the SIGA MFT tool for details on installation and update detectors Connect the SIGA MFT to the computer using the USB cable Double click on the desktop icon to start the TF 13029 Utility The TF 13029 opens Figure 2 13029E ISS 15JAN14 5 Disconnect the loop wiring from the panel Connect the SIGA MFT to the loop wiring Enter the Project Name and Loop Number in the TF 13029 window to help the report file Click File Start to begin the update process The utility generates a new report file with the timestamp in the each time the process is started When the process completes Figure 2 a new report file is placed on the See Figure 3 and Table 1 If there are more loops to update repeat steps 3 through 7 If required contact Customer Service to return detectors for a warranty using the RMA process or return the device to the original place purchase Use the report file generated from the utility when ordering RMA replacements To view the device serial number using the Configuration Utility CU to Tools Status Diagnostic Device History tab You can download a of the FSA CU from www edwards signals com if you do not have one 2 TF 13029 window 13029E ISS 15JAN14 5 3 Report 1 Report description column column not applicable this device device pass update needed column Ignored device on the loop is listed by serial number the results of the update update is not applicable to this device because it does not have same smoke chamber as a PD or PHD device and requires no utility attempted to update the device but was not successful device long term smoldering threshold was successfully updated device long term smoldering threshold is configured correctly and updated is required the device address total number of devices that were ignored by the utility because require no update 13029E ISS 15JAN14 5 Updated Unchanged to RMA Processed total number of devices that had the long term smoldering value updated total number of device that did not require updating is the total number of devices that need to be replaced under using the RMA process total number of devices on the loop that were identified and by the utility support 1 800 336 4206 1 860 284 3083 2014 UTC Fire Security Americas Corporation Inc All rights reserved 13029E ISS 15JAN14 5
