APPLICATION CIRCUIT
1. Three triggers application : Maximum 3 triggers allowed. The most general application used un EM22000
series. Refer to schematic 1 for detailed circuit.
2. Six triggers application : Maximum 6 triggers allowed. Keyboard scan circuit will be activated to detect extra
3 triggers which connect SAF1 with triggers. Refer to schematic 2 for detailed circuit.
3. Eight triggers application : Maximum 8 triggers allowed. Keyboard scan circuit will be activated to detect extra
5 triggers which connect SAF1 with triggers (TR4~TR6) and SAF2 with triggers (TR7~TR8). Refer to sche
matic 3 for detailed circuit.
4. One Key On/Off application : Only TR2 is provided and it will behavior as ONEKEY function Sequential
Mode. First time when it is pressed, it will play groups and when next press happened, it will stop playing. Refer
to schematic 4 for detailed circuit.
5. Press and playing group 2, Release trigger 2 will cause group 1 playing : TR2 is in level hold mode. SAF2 is
in STOP mode connected to TR1. Refer to schematic 5 for detailed circuit.
6. Power On Auto playing until release Key : Trigger 1 is level hold mode. V
and trigger 1 are connected to
push button. When trigger 1 is pressed, the V
will connect to batteries at the same time and level holde
playing happened. Please refer to schematic 6 for detailed circuit.
