Troubleshooting
Problem: I’ve hooked up the B1290 as per the installation instruc-
tions but nothing happens.
- Use a voltmeter to check that the power supply is properly connected. If
an AC adapter is being used, it should have an output of at least 12 volts DC
with a center-negative power connector. If the DC power source is con-
nected to the RADIO terminal block, it should have the positive lead con-
nected to terminal 8 and the negative lead to terminal 7 .
- Do not attach power to both inputs at the same time.
Problem: The B1290 will not program from a local programming
phone.
- If you do not hear the voice prompt to begin programming, check that the
programming phone is plugged into the PGM jack and not the PHONE
jack.
- If you hear the voice prompt to begin programming, but the B1290 does
not register your entries, check that you are using a tone phone. Sometimes
a pushbutton phone actually sends dial pulses rather than DTMF. You can
tell the difference by listening in the earpiece; pulse dialing sounds like
clicking, DTMF like tones.
- Check for the TONE LED on the front panel when a digit is being re-
ceived. Some phones send short bursts of tone rather than continuous tone
while the key is depressed. If the B1290 is not detecting DTMF, try another
phone.
- Check the setting of the receive level for the phone port. Since it is not pos-
sible to do this using the programming phone, it will have to done with the
programming software.
- Disconnect the RX input from the radio. Audio received from this input is
summed with the audio from the programming phone. If noise is being re-
ceived, it will affect the decoding of tones and the programming of the
voices. The RX input should always be connected to squelched audio.
Problem: The B1290 does not dial out over the telephone line when
an alarm occurs.
- Check that the phone line is plugged into the correct jack. The jack labeled
PGM is for a local programming phone; the telephone line should be
plugged into the PHONE jack.
- Check that the telephone is dialing from the correct directory (Program
Code 2). The B1290 has four separate directories: A, B, C and D. Check that
the telephone numbers are entered correctly in the selected directory, and
that the directory is not empty.
