The individual or group should have access to the door but AMT is showing denied entry tenant or deny entry schedule. Resolution Method 1 - Modify the Individual or Group Change the Type from Permanent to Temporary [Give a start date and time of yesterday and the end day several weeks in the future] Press OK until you see the I/NET splash screen Test the badge(s) Return the Individual/Group type back to Permanent Test the badge(s) Method 2 - Modify the Individual or Group Change the Type from Permanent to Temporary [Set the start date/time to 5 minutes in the future and the end date as several weeks in the future] Press OK until you see the I/NET splash screen Return the Individual/Group type back to Permanent Test the badge(s)

Issue Updating firmware from StruxureWare Building Operation and the still be usable with other BMS such as Continuum, I/A Series, I/NET, Sigma, and Vista Environment Site with more than one Building Management System  Cause Implications of updating firmware on a controller from the StruxureWare Building Operation side and still compatible with existing Resolution For the controllers available on the StruxureWare Building Operation network that have been configured, take precaution when updating the firmware and still expect compatibility with other systems. For example, at a Continuum site, with a b3 and the option to update of firmware from StruxureWare Building Operation, there are a couple of things to keep in mind. When selecting the b3, and the Update Firmware, it will ask you for the *.udp file. This can be downloaded from the extranet. The thing to keep in mind here is if you are using this controller in conjunction with Continuum, then pay particular attention to the Compatibility Matrix and the firmware which is compatible with the version of Continuum you are running. Updating a firmware that is not in line with the version of Continuum will create problems for the site. So when selecting the firmware *.udp, be sure of which firmware file you are selecting. The operating system in the b3 controller is no different between StruxureWare Building Operation and Continuum. The PE code may be different though, so he should be able to learn these controllers into Continuum as long as they have their user memory cleared out.  

Issue Building a database to take to a site and the doors do not show up in Netcon, though they can be controlled. Environment I/NET versions 2.10 and up using SCU 1284s. Cause The controller has not recognized the doors in the SCU and has to be readded in Netcon to be saved again. Resolution To resolve this there are a few simple steps that needs to be followed to get this to work again. Connect to the controller and then go to Edit/Host Computer/Network Configuration. Penetrate the Link Summary, Controller and then SCU. In the cnf column there should be a -- sign indicating that there is no communication to the device. Click on the delete button to remove it from the SCU. Close all the Editors and then go back to the controller. Go to Resident I/O Points, if the door point exists, delete it and close out of the editor. Open up the Resident I/O Points and re-add the point again and repeat Step 2. Save the doors now as Step would have a + sign indicating that there is communication to the device.

Issue Does the STR-250 work on Micro Regulators (MR)? Environment I/NET Seven STR-250, I/STAT, M/STAT I/SITE Controller and Micro Regulators (MR) Cause The STR-250 Wall Module is the replacement for the commonly referred to I/STAT sensor, still referenced in I/NET documentation.  The I/STAT is no longer available.  Resolution The STR-250 sensor is the replacement for the I/NET I/STAT, so installation and configuration for the STR-250 is as per this I/STAT. There are two documents that will provide assistance with this TCON126 and TCON299 (Chapter 21). The STR-250 full functionality must be installed on the I/STAT port of any I/NET device and configured as detailed in the above documents. Only one I/STAT port exists per MR. The M/STAT is still available and is used as the hardware tool for configuring the controller settings on all supported I/STAT devices, such as, all Micro Regulators (MR) variants, I/Site LAN Controller (Model 7728) and Xenta 102-AX.

Issue All Card Readers on a DPU are not working.  Messaging is not working, but able to release door points manually. Environment DPU 7920 - non-mipped DPU 7910 7793 Cause The DPUs and 7910 have limited memory resources for storing access control data.  If the system tries to allocate to much space for card data then the doors will not work properly. Resolution Option 1 Upgrade Hardware to SCU 1284s. You may also need to upgrade to a 7798C. Option 2 Reduce memory allocation to the door. Backup the Database to function as a restore Point Select Access>Individuals Modify a tenant's individuals Note the range of individual numbers. (lowest number and highest number) Close windows Select Access>Tenants Modify the tenant Change the number of individuals allocated to the lowest possible value Repeat these steps on all Tenants Perform an SLI restore and DPU restore on affected controllers Test badges. (the key difference to look for is the restoration of AMT messaging)

Issue After reading a valid card on a reader a Deny Entry Select message is displayed in AMT. Environment I/NET Seven and Access Control. Cause The reason for this is because the door that the card is being read on does not have a time selected for it to be granted access. Resolution Click on Access/Tenants and verify that the Tenant does in fact access to that door. Click on Access/Individuals and modify the person who owns the card Select Doors and when the Editor comes up, scroll over to the door in question, double click and the Time Schedules comes up Select the schedule that is appropriate and hit okay and close out the editor Read that card again and it should grant access now.

Issue Recommended method for replacing an MR-VAV-AX controller. Where to get ASC Parameters for the new device. Environment I/NET software all versions MR-VAV-AX controller Cause An MR-VAV-AX needs to be replaced on an existing VAV box. Resolution The ideal way to change an MR-VAV-AX or similar would be to use an airflow hood to calibrate when the device must be changed. However, if no airflow hood is available, see the options below: Obtain the ASC parameters of the existing MR before removing the device from service. Re-use the original settings. If these values cannot be recovered, then ask the customer for the original drawings or T&B reports on the device in an effort to properly establish correct duct diameter and total airflow. Rarely is this information readily available at the time of the change. Without such info, an estimation will have to be made. A rule of thumb is: 250 CFM per diffuser and an eyeball estimate of the duct diameter The pickup factor is left at factory default (3) or compared to other similar devices and an average of other pickup factors is used. For setting CHF, base it on the above estimate of 250 CFM per diffuser and make sure that the box just reaches 100% damper at the maximum airflow it is physically capable of at the AHU's normal static CLF is an estimate based on the use of the space and the temperature needs of the occupants. CLF is about 10% of the CHF.

Issue The PWM Transducer is responding as though it is receiving a continuous signal from I/NET ASC Environment I/NET software all versions Any I/NET ASC Cause The triac device on the ASC does not totally drop the voltage to zero (0V), thus the PWM input never sees a pulse. Resolution Install a 0.47µF capacitor between the input and ground terminals of the PWM transducer. It will take the bleed voltage to zero and the transducer will see a pulse value.

Issue A memory failure message in AMT for a DPU or SCU Controller When presenting a valid key card to a door reader, the LED on the SCU turns Green but the relay does not fire.  The relay can be controlled manually via the workstation in some instances. Environment I/NET Door Controllers  Cause This memory failure message is generated when the DPUs or SCUs do not have sufficient voltage supplied to the board. This can either be a bad 24 VAC Transformer or from a gel cell battery. In most cases if there is a battery backup of the controller, the gel cell battery has had a deep discharge applied to it. The charging circuit on the controller cannot recover the battery to its proper charge value. Even if there is a good voltage value from the transformer, the charging circuit load is so great, it restricts the main board of the necessary voltage to keep the RAM alive. Resolution Remove the two wires from the controller that go to the gel cell battery. Get a replacement battery as soon as possible.

Issue When purging alarm in AMT, and the I/O server is configured as serial port communication, there will be "No Reply" window popping up and Retry is useless. Environment I/NET Cause This may be caused the network communication issue. Or it may be due to other issues. Resolution Disconnect the Server from network or disable the serial port in I/O configuration. After the alarms are purged, return to the original setting.

Issue When swiping card, the status of door point in Controller Summary doesn't change. Environment I/NET Cause This is so designed in I/NET Resolution In I/NET, the status door point doesn't change when swiping card. So if interaction with swiping card is needed, you need to use Access Initial Control or create another real External point for the door point. (00/01 Ext apart from 08/09 Int)

Issue There is a Graphic Page issue in I/NET Seven rev 2.15 and below. Anytime you try to connect to a point thru a graphic page it gives you an error of "You do not have the Proper Password to do this." Environment Windows XP Pro SP3  I/NET Seven rev 2.15 and below Cause There is a Graphic Page issue in I/NET Seven rev 2.15 and below. Resolution Upgrade the site to I/NET Seven rev 2.31 or above (up to I/NET Seven rev 2.4X). The Graphic Page issue was fixed in these versions.

Issue Point Name Limitations in I/NET Environment I/NET Cause I/NET limits point name length in order to conserve memory usage on controllers Resolution All Resident I/O points in I/NET are limited to 16 characters Indirect Points are limited to 11 characters

Issue Graphics not functioning after moving I/NET to a new machine that uses direct serial connection Points are not displaying data but links between pages still work. Environment I/NET Seven Direct Connect Cause I/NET link and station numbers must be correct for I/NET graphics to work Resolution You can verify that this is the issue by editing a graphic and determine the link address of a displayed point. If this link is not available when you try to connect to the controller then you will need to change your I/NET configuration. Open I/NET Configuration Modify the Active Profile Ensure that the System and Hardware Addresses configured match the configuration of the original computer

Issue Show the images stored in the database on a webpage using PHP Image location Picture Environment I/Net Cause The images are stored at  (Individuals.Imagepath) in the database Resolution The best method might be to query the database for the path (Individuals.Imagepath) where the picture is stored and present the picture to the web page from there.
