Figure 1: The D720 Command Center
5.1 Armed Status Indicators
Armed Status Indicators show the armed condition of the area to which the command center has been assigned. (Command
centers are assigned to areas in the Cmd Cntr Assignment section of the panel program). Three different indicators show the
area armed status:
Perimeter – When this indicator is lit, the area perimeter points are armed. During exit delay time, this indicator flashes
slowly.
Interior – When this indicator is lit, the area’s interior points are armed. During exit delay time, this indicator flashes slowly.
Instant – When this indicator is lit, the area is armed without entry/exit delay time.
5.2 Point Status Indicators
The command center contains eight numbered indicator lights, which are used to annunciate the condition of the area’s
protective points (see Figure 1).
Point Fault – While a point is faulted, its indicator lights steadily. When the point is restored to normal, the indicator goes
“off.”
Point Alarm Memory – A point alarm memory condition causes the indicator light to flash “on” and “off” rapidly. The
indicator continues to flash rapidly until the system is next armed or [COMMAND][4] is entered.
Bypassed Point – When a point is bypassed, the point’s indicator flashes “on” and “off” slowly. The indicator continues to
flash slowly until the system is disarmed, or with some systems, the point may be unbypassed.
Note: Protective points may be programmed as invisible. When programmed invisible, the status of the point is not
displayed for alarm conditions.
