maximum allowable distance of previous versions. Custom cables lengths are required for any other distances.
Substituting cables is not recommended.
The alarm and relay connections on the expander are the same for the B1290 connections. Use the shielded cable
provided to connect between the EXP connector on the B1290 and EXP on the expander. On subsequent expanders,
use the cable supplied with the expander to connect between EXP on one expanders and EXP on the next.
Next set the rotary switch on the expander to configure its ID number.
(refer to the B1292 manual for more information)
If the expander address is changed, the unit must have power removed and then reapplied in order for the master to
recognize its new address. All the expander’s programmed parameters, including the voice messages, are stored in
the main ProTalk Plus and are downloaded on power-up.
The expander database will be automatically transferred from the ProTalk Plus if an expander address is changed or
an expander is replaced.
The expander requires its own +12/+24 VDC and GND connections. Be sure that all units, master and expander(s),
are always powered up and down together. Do not connect or disconnect expander cables when the system is
powered up.
The PWR LED lights when the power is on. The expander also has an RX LED which lights when it is being polled
by the master B1290, and a TX LED which indicates when it is responding.
Power-up Sequence
Once the installation is complete, DC power can be connected to the B1290. On start-up, the B1290 will go through
a self-test sequence; ending with the firmware version being spoken over the speaker and the RUN LED staying on
solid.
The telephone line may then be plugged in as the last connection.
Ensure that the telephone is connected into the
PHONE port on the B1290.

Introduction
Now you are ready to begin programming. When the B1290 is initially powered up, it will prompt you to input
three parameters which must be entered before it can operate — the voice messages, a list of telephone numbers and
the Acknowledge Code. Once these values have been entered, with its default settings, the unit will function as a
telephone dialer when an alarm is present. If you require the B1290 to perform more advanced functions, continue
on to the chapter where the Program Codes are explained in detail.
Before you start programming, there are a few points with which you must be familiar. First, although it is possible
to program the B1290 remotely by calling it up over the telephone line, it is assumed that when you initially install
the unit you will be using a local programming phone. The B1290 must be programmed with a phone which sends
DTMF tones (Touch Tone); it will not recognize the signals from a phone which sends dial pulses.
The B1290 is designed to be user friendly. When you listen in the earpiece of the programming phone, you will
hear spoken messages. These are called voice “prompts”, and they tell you what information the B1290 is expecting
you to enter. Whenever you program a new value, the B1290 will immediately speak that parameter back to you, so
you will know right away whether the code was entered correctly. You can change a parameter as many times as
you like before going on to the next one. If you make a mistake, such as entering a value outside the range for that
parameter, the B1290 will immediately let you know by announcing
Error
. And if you get confused, just hang up
the phone and start again. The B1290 will start again at the beginning when you pick up the handset.
The other feature you need to know is how to enter data. If you were entering information from a keyboard or other
terminal, you would use the “Enter” key or a “Carriage Return”. A telephone does not have this key, so we
substitute the code
for “Enter”. The two “stars” (asterisks) must be entered one after the other, with no more
than one second between the beginning of the first digit and the beginning of the second. This is a much longer time
than most people think, and there is no need to rush when entering the code. If you enter the digits too fast, the
telephone will only recognize one
. You may get an
Error
message if this happens or else the B1290 will ignore
