The SSD has six LEDs and a sounder to indicate the status of the fire alarm panel.
The LCD indicates the state of a specific event. The SSD also has push buttons that allow the user to scroll through the events list, control the sounder and acknowledge events displayed on the LCD.
The SSD must be configured in the Zeus Programming Tool as Display only. Refer to the Programming section for information on configuring the system.
Controls and Indicators
The front panel of the SSD contains 6 LEDs, 1 LCD display, up and down navigational buttons and a Local Acknowledge button 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 supervisory 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. |
TROUBLE | Yellow | Normally OFF. Indicates that there is no trouble event in the system. ON (flashing). Indicates that at least ONE trouble event is unacknowledged. ON (steady). Indicates that ALL trouble events have been acknowledged. |
AUDIBLES ON | Yellow | Normally OFF. Indicates that NACs are in supervisory mode or that ALL silenceable NACs have been silenced. ON (steady). Indicates that at least ONE NAC has been activated. |
AUDIBLES SILENCED | Yellow | Normally OFF. Indicates that NACs are in supervisory mode or that there is at least ONE activated NAC in the system. ON (steady). Indicates that previously activated NACs have been silenced. |
When both AUDIBLES ON and AUDIBLES SILENCED LEDs are in the OFF state, it indicates that all NACs in the system are in supervisory mode.
The Sounder operates as follows:
SOUNDER | Normally OFF. Indicates that the system is in supervisory mode or all events in the system have been acknowledged or that a push button has been pressed. ON-STEADY. Indicates that at least one unacknowledged alarm is present in the system. ON-PULSING. Indicates that at least on unacknowledged non-alarm (security, supervisory, or trouble) event is present in the system (and that there are no alarm events present or all alarm events have been acknowledged). |
When the SOUNDER DISABLE option is selected in the Zeus Programming Tool, the sounder remains OFF, regardless of the status of the system.
The push buttons and their functions are defined as follows:
LOCAL ACK | During Supervisory Mode: Activates the LCD backlight for 10 minutes. When Event Is Displayed: Turns OFF the sounder without affecting the logic of system. |
UP ARROW | During Supervisory Mode: Activates the LCD backlight for 10 minutes. When Event Is Displayed: Displays the event with the next higher priority. (See Figure 2 for more information about the differences between U.S. and Canada.) |
DOWN ARROW | During Supervisory Mode: Activates the LCD backlight for 10 minutes. When Event Is Displayed: Displays the event with the next lower priority. (See Figure 2 for more information about the differences between U.S. and Canada.) |
The events are displayed one at a time and cycle through a circular list once the most recent event message is reached. See Figure 2.
LCD (See Figure 3)
The LCD backlight activates for 10 minutes when an event occurs or when a push button is pressed.
Supervisory Mode:
Line 1 - Current date and time
Line 2 - Custom message and system ID
Line 3 - Custom message and system ID
Line 4 - Blank
Active Event Mode:
Line 1 - Event Status, module/device address, date and time of the event
Line 2 - Custom message for the module/device, acknowledged/non-acknowledged
Line 3 - Event category or trouble type, sequence number of the event.
Line 4 - Total number of Alarms, Supervisory, Security, and Trouble events in the system or vectored to the SSD.
