8. UNIT ADDRESS DIP SWITCHES
Example 1:
1000 0000 - Zone 1 to 4
0110 0000 - Zone 6 to 9
MASTER & SLAVE SETTING
ON = MASTER
OFF = SLAVE
10. EMERGENCY OVERRIDE TERMINAL
11. AMPLIFIER ZONE OUTPUT CONNECTOR ( ZONE 1 - 8 )
TIME OUT SETTING
ON = TIMER 5 MIN
OFF = TIMER INFINITY
TD6400 | 2 x 4 CH DECODER / ZONE SELECTOR
PAGE 3
Each TD6400 caters for 2 sets of 4 consecutive zone outputs. Zone assignment is achieved by configure the DIP switch
setting to the binary number of the starting zone. TD6400 allows flexible starting number of each group of zones. Maximum
zone number allowed is 138 ( starting zone must be set to 135 ).
External switch ( eg. from emergency paging mic with dry contact ) can be connected here, which shall trigger the built in
relay when pressed. This shall then provide a dry contact in which would enable the installer to apply several functions
such as providing 24V DC output for volume controller overriding purpose, trigger external device or link to BAS system,
etc. Refer to page 10 for connection diagram.
Outputs from amplifiers are connected to these terminals and speaker zoning is configured to the respective
unit of amplifier. The user has the flexibility to configure the zoning system as each zone comes with single amplifier
output connection. Please observe polarity when terminating the amplifier / speaker zones and ensure that each zone
is not overloaded ( max load 500W l00V line ).
GROUP A
7. BALANCED OUTPUT ( GROUP A & GROUP B )
Balanced audio signal from paging mic and BGM are connected to amplifier audio inputs via these terminals.
When user activate Group A zones via TD6400 front panel switches, the GROUP A - BALANCED OUTPUT will play
BGM, and activation from a paging mic will broadcast paging announcement.
While BGM is playing, activation of paging mic will override the BGM to the group zones and broadcast paging
announcement. Paging signal shall have priority over BGM.
9. DIP SWITCH
DIP setting for Time out, Master and Slave setting
1010 0000 - Zone 5 to 8
1000 0111 - Zone 135 to 138
GROUP B
Note: On DIP switch, ON corresponding to binary 1; OFF corresponding to binary 0.
