T400 Controller Facilities Manual

9.7 MANUAL STEP-ON MODE

A Manual Step-on facility can be provided when a Police Manual Panel is fitted. See

Figure 9.4.

If the Manual Step-on facility is used and located behind the Manual access flap on the

side of the controller, the Manual facility described in section 9.6 is transferred to the

internal manual panel.

It is possible to change stage under Manual Step-on Control by operation of a push

button on the Police Manual Panel. When Manual Step-on has been selected on the

Police Manual Panel, the controller, subject to the Mode Priority, will go into Manual

Step-on Mode. The order in which stages are introduced in Manual Step-on is

predefined in configuration (site data). The push button on the Police Manual Panel is

operated to make the controller move on to the next designated stage. Having arrived

at the next stage the controller may do one of two things depending on the option

selected.

(a) Remain in that stage indefinitely, the controller being ready to respond to

another operation of the push button, which if operated will send the controller

to the next predefined stage,

(b) stay in one stage for a fixed period defined at configuration and then

automatically move to another pre-defined stage. The controller is then ready

to respond to a further push button operation.

The user may change the operation between (a) and (b) as required, by means of the

handset.

There is a separate Push Button for selecting All Red. When this Push Button has been

operated the controller will, subject to any safety periods, change to the All Red stage.

The controller will stay in the All Red stage until the Manual Step-on Push Button is

operated when the controller will move to the next stage in the cycle following the

stage prior to the call to the All Red stage. Alternatively, if the manual mode is

switched off the controller moves to the stage required in the new mode.

The Manual mode should be disabled after use by operating the Manual Disable

pushbutton.

9.7.1 Manual Disable Switch (Police)

A micro-switch may also be fitted to the Police manual step-on panel to disable manual

step-on mode when the door is closed. If the manual panel is subsequently opened,

manual step-on mode is not re-entered; to select manual step-on mode it is necessary

to operate the Enable push button.
