Low Voltage DC Triggers
The Suite 7.1 has four separate low voltage trigger outputs that can be used to independently trigger
other components such as power amplifiers, video projectors, or AC controllers. Each of these triggers
can be individually activated depending on how it is programmed during setup. Each of the four triggers
provide 12 Vdc at 100 mA per trigger.
Required Cable and Connection
You can use any common two-conductor 18-22 AWG “zip cord” or hook up wire or to connect the
DC triggers to the Suite 7.1. For each of the four triggers, connect a wire between ground (pin 1) and
each of the four trigger terminals (2, 3, and 4). Depending on the component or device you are triggering,
you will need to terminate the other end to accommodate it.
1. Connect one lead of the two-conductor wire into terminal 1 of the Suite 7.1’s DC trigger connector.
2. Connect the other lead of the two-conductor wire into terminal 2 of the Suite 7.1’s DC trigger
connector.
3. Connect the other end of the lead connected to terminal 1 to the negative DC terminal of the
component to be triggered.
4. Connect the other end of the lead connected to terminal 2 to the positive DC terminal of the
component to be triggered.
5. Repeat Steps 1-4 for each additional DC trigger connection.
Important Advisory Disabling the Internal BRT-1 for Multiple Suite 7.1s
The Suite 7.1 comes equipped with an internal baud rate translator. This allows it to be easily controlled
at 1200 baud with an infrared remote control or at 19200 baud on the ADA bus in a Suite 16 or other
ADA multiroom system. To insure proper operation of the ADA bus, there can only be one BRT-1 in
the system. If you are using multiple Suite 7.1s, you will need to disable the BRT-1s in all but one Suite
7.1. If you have installed a separates BRT-1 on the system, be sure to remove it when you install a Suite
7.1. Note: Since the base version of the Suite 7.1 has no front panel display or controls, it does not have
a BRT-1, so the above advisory does not apply.
To disable the internal BRT-1 when using multiple Suite 7.1s on a single ADA bus
1. Remove the power to the Suite 7.1
2. Remove the top cover panel screws on the Suite 7.1
3. Locate the internal BRT-1 near the rear left corner of the Suite 7.1
4. Disconnect the orange 8-pin AMP connector that connects the BRT-1 to the main PCB of the
Suite 7.1.
5. Replace the top cover panel and screws.
