operator using the LED/Switch displays.

An example of how the page commands work is illustrated in

Figure 1-17. This figure shows a nine story high rise building,

with a fire on the 6th floor. The fire plan requires the evacuation

signal to be sounded on the fire floor, floor above the fire, and

floor below the fire. The alert signal is required to sounded in all

other areas of the building except the stairwells. The first column

(Fire Alarm) shows the automatic responses on the affected

floors according to the fire plan.

Figure 1-17: ASU Page Command Example

The Page to EVAC command replaces the EVAC signal with the

Page signal, as shown in the figure’s second column.

The third column shows the Page to Alert command response, all

the Alert signals have been replaced by the Page signal.

The All Call Minus command directs the Page to the areas which

are not receiving the EVAC or Alert signals, i.e. the stairwells.

In the fourth column of Figure 1-17, the stairwells receive the

Page signal when the All Call Minus command is used and do

not automatically receive either the EVAC or Alert signals.
