Set the Address
Assign SmartSeries stations in ADVANCE systems a unique address using the hexadecimal switches,
S1
(Hi Address) and
S2
(Lo Address), for the SmartSeries option to function properly.
•
Each switch contains 16 settings, labeled 0–F. A small arrow on each switch indicates the setting.
•
The station address is the high address setting followed by the low address setting.
For example, to assign an address of 05, the high station address switch,
S1
, is set to 0 and the low
address switch,
S2
, is set to 5.
•
Valid address settings are 05 to FE.
•
Access the address settings through holes in the bottom of the ICS SmartSeries amplifier.
•
Record the address assigned to each station in the system.
•
When replacing an amplifier
: Note the address of the existing amplifier and use the same address for
the replacement amplifier.
•
In a system without an ADVANCE head end
: Set the SmartSeries station address to 04 (
default
).
Level Adjustments
GAI-Tronics recommends using a No. 10440-002 Maintenance Cable (
purchased separately
) to perform
the following adjustments (see Figure 14 for component locations).
Speaker Mute
The amplifier can mute the associated speaker during page operation to eliminate feedback. To mute the
associated speaker:
1.
Remove the amplifier from the enclosure and place it on a stable surface.
2.
Open the amplifier as previously described.
•
P11 on the Main PCBA mutes the speaker during page activation when in the
EN
position
(default).
•
P11 in the
DIS
position allows broadcast to the speaker during paging.
Speaker Gain
Jumper
P9,
on the main PCBA, limits the maximum speaker output level. To change the speaker gain:
1.
Remove the amplifier from the enclosure and place it on a stable surface.
2.
Open the amplifier (see the Open and Close the Amplifier section).
•
Jumper
P9,
in the
30W
position (
default
), represents a 30-watt maximum output.
•
Jumper
P9,
in the
2W
position, represents a 2-watt maximum output.
