Notes:-

(i) On an intersection controller, the supply for the audibles would

originate from a transformer mounted in the controller as shown in

Figure 18.2.

(ii) For a pelican controller, the supply will come from the 2-phase driver

board.

(iii) Note that the high current outputs are used, i.e. the contacts are

protected by a series resistor of 22Ω.
