When the SSD-C is configured as Display only, pushbutton presses to any control
keys will not affect the logic of the system, but will silence the SSD-C audible signal
regardless of the position of the security keyswitch.
When the SSD-C is configured with System Control, the security keyswitch has to be
in the ENABLE position for the control pushbuttons (ACKNOWLEDGE, SILENCE,
UNSILENCE and RESET) to respond.
When the SSD-C is used in a No Vectoring application, all events that occur in the
system are displayed on the SSD-C. If the SSD-C is configured with System Control,
it can take full control of the system (Acknowledge events, Silence/Unsilence
Audibles and Reset the system).
Queue Vectoring displays only the specific event type (such as Alarm only, Trouble
only, etc.) and is set by deselecting any
Display
type in the Zeus Programming Tool.
An SSD-C with System Control has control of the system as long as the system
events are the same event type for which it is configured. Otherwise, it responds as
Display Only. For example, if the SSD-C is configured as an ALARM-only display and
there are only alarms present in the system then the SSD-C will have full system
control. However, if for the same SSD-C, there are alarms and troubles in the system,
then pressing a control push-button (Acknowledge, Silence, Unsilence or Reset) on
the SSD-C will have no effect on the system. The corresponding LED of the queue
type not vectored will activate momentarily to indicate to the user that an event of a
different queue is present in the system.
Controls and Indicators
The front panel of the SSD-C contains 6 LEDs, 1 LCD display, up and down
nagivational buttons, a keyswitch, and Acknowledge, Silence, Unsilence, and Reset
buttons, as shown in Figure 1.
The LEDs and their functions are defined as follows:
ALARM
(Red)
Normally OFF. Indicates that there is no
alarm event in the system.
ON (flashing). Indicates that at least ONE
alarm event is unacknowledged.
ON (steady). Indicates that ALL alarm
events have been acknowledged.
SUPERVISORY
(Yellow)
Normally OFF. Indicates that there is no
supervisory event in the system.
ON (flashing). Indicates that at least ONE
supervisory event is unacknowledged.
ON (steady). Indicates that ALL supervi-
sory events have been acknowledged.
SECURITY
(Yellow)
Normally OFF. Indicates that there is no
security event in the system.
ON (flashing). Indicates that at least ONE
security event is unacknowledged.
ON (steady). Indicates that ALL security
events have been acknowledged.
