Connecting Bewacom to a telephone
system
An analogue extension (two wires) must be used
for the connection of Bewacom. The telephones
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.
