6.3.3 Setting Momentary and Maintained Modes
This section introduces the momentary and maintained modes.
Figure 6-10
[Momentary Mode] Pushbutton switches that are normally open and stay closed only as long as the
button is pressed. Momentary switches allow turn-on or turn-off from multiple locations. For example,
certain premises have a designated entry/exit door. When the staff enters the entry door, the system
starts monitoring. When the staff leaves from the exit door, the system stops monitoring.
[Maintained Mode] Push-on/push off button switches that stay open until thrown, and then stay closed
until thrown again. Maintained switches are convenient for only one switch location.
For example, in the business hour when the door is opened, the system stops monitoring; in the
non-business hour when the door is closed, the system starts monitoring.
