Supplementary Power - Power Supply

Use supplementary power if the control’s aux. power load for all devices exceeds 600mA (suggested power supply: AD12612). Connect as shown in Figure 6. Be sure to connect the negative (–) terminal on the power supply unit to terminal 4 (AUX –) on the control.

Note: Keypads powered from supplies that do not have a backup battery will not function if AC power is lost. Make sure to power at least one keypad in each partition from the control’s auxiliary power output.
