Connecting Bewacom to a telephone sys-
tem
An analogue extension (two wires) must be
used for the connection of Bewacom. The tel-
ephones to be called by Bewacom must be able
to send a standard tone signal to Bewacom for
the door release function to work.
How to test whether the telephone system
meets the requirements or not:
1� Connect an ordinary push button telephone
to the Bewacom extension, and dial any
of the other extensions on the telephone
system.
2� Ask the person answering at the other end
to press the 5 key on the telephone keypad.
If a tone is heard, Bewacom should work
correctly.
