( 1 ) Latched by the GSC+The above table lists the following abbreviations:ALM - Alarm ModuleH - The horn is sounded.INT - The signal source is internal to the module.LAT - "LATCHED" alarm faultLI - The data link from the GSC+ is the signal source.RAN - Remote AnnunciatorSW - One of 4 switches is the signal source. The number indicates the switch that is the source of the signal.TD - A 10 second delay occurs before the fault is annunciated.TIM - A 60 second time delay occurs before the fault is annunciated.When an alarm fault occurs, the corresponding indicator flashes. The indicator flashes at two Hz and the horn sounds. If the alarm fault is NOT LATCHED the indicator turns off when the alarm fault ceases. The horn also turns off when the alarm fault ceases. If the alarm fault is LATCHED, the indicator continues to flash until the "Acknowledge/Silence" input is activated. Refer to table 1 for alarm faults that are latched. See table 1 for the indicator and horn functions for each operating mode. Modes of operation are listed in table 2. Normally, the input to switch 3 (terminal 10) and the input to switch 4 (terminal 11) only operate indicator 7 and indicator 8. However, the input to switch 3 and the input to switch 4 can also operate the horn. Connect terminal 10 (the input to switch 3) to terminal 3 and connect terminal 11 (the input to switch 4) to terminal 4.Alarm Silence
Activating the alarm silence switch (4) causes the horn to cease. Also, activating the alarm silence switch (4) causes the indicator to be continuously illuminated.Data Link Malfunction
If the data link malfunctions, the indicators that are controlled by the data link flash at 0.5 Hz. The indicators that are controlled by the switches function normally. Lamp Test
Activating the lamp test switch (3) results in sounding the horn and turning on all indicators continuously for 10 seconds or until the switch is deactivated. Mode Selection
