Setting the ECS-DUAL50W Mode

When the ECS-DUAL50W is connected to an IFP-100ECS or IFP-1000ECS version 13 or prior, see
Figure 4-71 to set the amplifier mode. Version 14 or later, the mode is set using the SKSS, Silent
Knight Software Suite and the DIP switch mode selector is ignored.
When the ECS-DUAL50W is connected to an IFP-2000ECS, IFP-300ECS or the IFP-2100ECS the
mode is set using the SKSS-3, Software and the DIP switch mode selector is ignored.
The amplifier modes are as follows:
• 50 Watt with Backup - Amp A powers Audio Circuits 1 - 8. Amp A is backed up by on-board Amp B.
(Default, DIP setting at 2).
• 100 Watt with no Backup - Amp A powers Audio Circuits 1 - 4. Amp B powers Audio Circuits 5 - 8.
There is no backup. (DIP setting at 1).
• 100 Watt with Backup (requires ECS-50WBU) - Amp A powers Audio Circuits 1 - 4. Amp B powers
Audio Circuits 5 - 8. The ECS-50WBU will backup Amp A or Amp B but never both. (DIP setting at
3).
If the ECS-DUAL50W is connected to an IFP-2000ECS or IFP-2100ECS system and configured to
operate in a dual channel setup, Amp A and/or Amp B is not restricted to which Audio Circuits it can
power. However, both can never power the same Audio Circuit.

Test Switch use

4.8.9.1 SW1 - AMP A

Switch should be moved to the "ON" position for normal operation. Move this switch to the "Test"
position to test backup amplifier.

4.8.9.2 SW2 - AMP B

Switch should be moved to the "ON" position for normal operation. Move this switch to the "Test"
position to test backup amplifier.
Note: Please allow up to 3 minutes for backup amplifier to engage.

Connecting AC Power

At installation, connect the AC terminals to the power source as shown in Figure 4-72. It may be
necessary for a professional electrician to make this connection.
