Question Why does the Access Easy Controller (AEC) version 2 say, "Door already in use" when trying to delete a reader board? Answer This message is displayed because the door is currently linked to other options in the software.  Verify that the doors on the board you are trying to delete are not linked to any Criteria, Advance I/O, Access Level, or other areas of the configuration.  Once all the links are removed, you will be able to delete the reader board from the configuration. ...

Question The central station received a message of No Acknowledgement Received, which may have been shown as X71 in 6500 mode or NYU0001 in SIA mode. What causes this problem with the C900TTL-E or C900V2 module? Answer The message indicates that the C900 module relayed the message to the central station receiver, but the panel has not responded to the acknowledgement request (kissoff). Check the dip-switch settings for the communication format. Verify the communication format is correct on the C900, and the same communication format is selected in the panel. Verify that the C900 firmware version is compatible with the selected communication format (see C900 module's installation manual for a compatibility list). Check the panel itself for a potential issue, such as a phone cable, ground fault, or power problem. Verify that the C900 module is getting minimum voltage required, 12 to 24 volts DC. Ensure that the power supply for the C900 is a dedicated source of filtered DC voltage, and it can supply enough current for the C900 module (~280mA). ... View more

Question What can cause a panel sending Contact ID to produce Data Errors in the receiver? Answer Verify the length of the data error. A panel sending contact ID will send 16 digits for the Contact ID signal. Common causes of the panel not sending the correct number of digits include the following:  - Voice over IP with Low Sample Rate or Line Compression  - Line card or Line Terminator Card on the receiver (D6600 only)  - Panel problem (Corruption, Bad Dialer, etc)  - Noise on the phone line There is a checksum value in the Contact ID signal. An incorrect checksum will cause a data error. An invalid checksum value may be caused for the same potential reasons as a dropped DTMF digit (see list above). Possible fixes for the problem include the following:  - Reprogram the field panel  - Swap panel  - Use a dedicated, analog phone line  - Swap the Line Card and Line Terminator Card in the receiver  - Have a qualified telephone technician check the phone line on the site with the panel or at the receiver for problems.   ...
