Fire Alarm Interface
The G920D may also be used to
control audio equipment in the
event of a fire alarm being
activated. A volt-free normally
closed switch is required from the
fire-alarm panel. This should be
connected to the two terminals
labelled “AL” (first, remove the link
b e t w e e n t h e t w o t e r m i n a l s )
Permission to connect to the fire
alarm circuit should be obtained
from the alarm maintenance
company. Alternatively, if the fire
alarm interface is not being used, and the audio equipment should need to be
disconnected for any other reason (e. g. from building security) then this can be
achieved by connecting a normally closed switch to the “AL” terminals.
If the fire alarm interface is not being used at all then do not remove the link
between the two “AL” terminals: removing the link will cause the output to be
disconnected.
The green indicator flashes if the alarm input has been activated.
Connecting the LED indicator panel.
The G920B remote indicator panel should be connected to the terminals marked
"+RYG" using four core cable as shown. + is the common positive supply. R, Y and G
connect to the red, yellow and green indicators respectively. These correspond to the
terminals on the G920B. Up to four G920B indicator panels may be connected to one
control unit. The G920B panel is not supplied as standard with the control unit, and
may be purchased from an Eagle dealer.
