    My ultimate question is, why does a buzzer sound 6 times (in a pattern of 1 beep, then 2, then 3) on a Voyager, over the top of the normal door hustle alarm which is just several repeated short beeps, just before the doors close?

    I believe that services operated with two members of staff have a signal buzzer which sounds at the guard's door controls and in the driving cab, but I thought that was used to confirm that doors were all correctly closed and the train was ready for departure, not to indicate closure of the doors.

    Am I correct about this?
    Is the sound I'm hearing on the Voyagers an unusual use of this signal buzzer, or something else entirely?

    On the Voyager the TM tells the Driver to close the doors via the bell-buzzer.

    1-2 is the close doors code which the Driver repeats and then closes the doors. Once the doors are closed 2 (train ready to start) is given and repeated.

    3 on the bell-buzzer is not used during dispatch.

    Sometimes called a "10-bell departure". On at least one occasion the TM turned a key which did the 1-2 beep to the driver, but then had to use a button for the remaining two. So, I guess it saved a little bit of wear on the button?

    Not quite.

    The TM "keys in" to the control panel by the door they are using, in order to effectively tell the train not to close the door they're at.

    They begin the despatch process by turning their key into the panel and pressing the green "speak to driver" button 1-2.

    (Driver acknowledges by giving the TM 1-2 back on the buzzer and closes the doors, apart from the one the TM is at)

    After performing platform checks etc. The TM returns back onboard the train, presses the door close button. Waits for the door to completely close, before giving another two beeps on the buzzer to the driver.

    Well it was a while ago, but I'm sure it was the clicking of the key from one position to another that caused the beeps; it was much quicker than the very deliberate 1-2 I've heard on other occasions, and I'm sure they didn't press the button at all for it. The reply beeps were definitely much slower.

    Is this a normal despatch procedure? I was under the impression that on most rolling stock, the guard's panel has door release and close buttons, and except on DDO services, the driver is not involved in the despatch procedure until they are indicated by the guard to depart by two beeps on the buzzer. But I could well be wrong.

    When Southern briefly had some 375s from Southeastern, apparently the guards couldn't close the doors if they were in one of the other cabs, so they had to use a 10-bell departure.

    Yes, it's the normal method of working for Voyagers. You will notice there is no Guards door control panel.

    On Voyagers it is the driver who releases the doors. No door release buttons are provided for the Guard. Nor can the Guard close the doors hence instructing the driver to do so. Once the guard has put his key in this creates a "local" door to enable the dispatch process to be carried out. After the driver has closed the rest of the doors the guard can close their door and give and receive 2 buzzes to give the RA.
