Stampa la paginaAlways check the function of all KETS phones after any replacement has
been made. If any individual phone does not perform as expected, it is usually
because the above procedure has not been followed. In this case follow
these steps to recover:
disconnect power from all the phones (using the LTU switch),
•
take all the handsets off hook,
•
turn the LTU switch back on
•
Replace all the handsets one by one
•
This will ensure that every phone acquires a unique address.
Note this situation can only occur as a result of maintenance activity, not
during normal operation or as a result of power or line interruption.

Operation / Testing
Normal operation of the phone is as follows:
Open the door - the illumination panel will come on
Lift handset - dial tone is heard but the call does not start.
Press button - ring tone is heard until the call is answered.
The call is cleared when the signaller hangs up, regardless of whether the
user hangs up.
When a call is made from the signal box back to the crossing, all KETS
phones on the line pair will ring.
When a handset is lifted the call is connected to that phone, and all the other
phones will stop ringing.
