Problem: How can I prevent unauthorized personnel from calling up the B1290 and altering its
programming?
- In its default condition, the B1290 does not require any type of password. If you wish to enter one, refer to the
Access Code in the DTMF Codes section (Program Code 3). If an Access Code is programmed, anyone calling the
B1290 will receive a report of its status, but it will prompt the caller to enter the Access Code before allowing them
into the programming mode.
Problem: Can I use the
character as part of my DTMF strings? Won’t this be confused with the
“Enter” code?
- The and characters may be used as a part of any programmable DTMF string. The only time you must be
careful is when entering an asterisk () as the last digit in a string. Be sure to wait more than one second after
entering the last digit before hitting Enter (); otherwise the last will be interpreted as part of the Enter code.
Problem: The B1290 has lost its programming.
- As it runs, the B1290 is constantly performing internal self-checks, and on rare occasions it may find that a
memory location has been corrupted. If that happens, the B1290 resets all programmed parameters (except the voice
messages) to the default values. At the same time, it will announce Program Code Error over the radio. As the
telephone directories have been lost, the B1290 cannot dial out to report the failure over the phone. The only way
you will be able to tell that something has gone wrong is by phoning the B1290; it will announce a Program Code
Error as soon as it answers the phone. In order to have some local indication that an error has occurred, hook a local
speaker into the radio connections.
The most common causes of a memory loss are power spikes which enter the board through the power, ground,
telephone line, or radio connections.
Problem: I tried to change the telephone numbers and now the B1290 will not dial out at all.
- Check the programming for Directory A to be sure that the correct command sequence is entered. If a Directory
Control Code is being used, make sure that the B1290 has not been changed to a directory that disables the alarm
reporting. This would be the case where a directory contains the single Wait command or possibly commands for
only the radio port.
