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
anAC adapter isbeing used, itshouldhave anoutputof atleast12 voltsDC
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
notregister yourentries, checkthatyou areusing atone 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 shortbursts of tone ratherthan continuous tone
while the key is depressed. If the B1290 is not detecting DTMF, try another
phone.
-Check thesettingof thereceive levelforthe phoneport. Sinceit isnotpos-
sible to do this using the programming phone, it will have to done with the
programming software.
- Disconnect the RXinput fromthe radio. Audio received from thisinput is
summed with theaudio 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 thatthe phoneline isplugged intothe correctjack. The jacklabeled
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). TheB1290 has fourseparate directories: A,B, C andD. Checkthat
the telephone numbers are entered correctly in the selected directory, and
that the directory is not empty.
