Table 2
ALM = Alarm Module    
H = Horn is sounded    
INT = The signal source is internal to the module    
LAT = LATCHED alarm fault    
LI = The data link from the GSC is the signal source    
RAN = Remote Annunciator    
SW = One of 4 switches is the signal source (the number in parentheses indicates which switch is the signal source    
TD = A 10 second delay occurs before the fault is annunciated    
TIM = A 60 second delay occurs before the fault is annunciated    When an alarm fault occurs, the corresponding indicator flashes. The indicator flashes at two hertz 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. See Table 1 for LATCHED alarm faults as well as the indicator and the horn functions for each operating mode. Normally switch input 3 (terminal 10) and switch input 4 (terminal 11) only operate indicators 7 and 8. However, switch inputs 3 and 4 can be made to also operate the horn. Connect terminal 10 (switch input 3) to terminal 3 and connect terminal 11 (switch input 4) to terminal 4. Alarm Silence
Activating the alarm silence switch (4) causes the horn to cease and the indicator to stay on continuously.Data Link Malfunction
If the data link malfunctions, the indicators that are controlled by the data link flash at 0.5 hertz. The switch controlled indicators 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
