5. Trigger Delay Adjustment

This screw driver adjust potentiometer determines the amount of time needed to keep the circuitry activated to

complete a page. Follow the indicator arrow to adjust the time. Note: There are a few milliseconds of delay even if the

unit is set to zero. It is suggest not to set to Zero for paging application due to pauses in ones message during a page.

This will prevent annoying repeated triggering before a page is completed.

6. Line Level Trigger Threshold Adjustment

When using the Line Level input for circuit trigger activation, you can set the threshold voltage to activate the relay

trigger. The trigger range is from 10mV to 3V AC. To adjust, turn the screw driver trim pot to the desired setting as per

the information on the cover.

7. Line Level Trigger Input

This input allows the unit to be activated by a audio line level signal. The input can receive signals from 10mV

to 3V AC. Wire as per the information on the box. To adjust the threshold trigger point use the Line Level Trigger

potentiometer adjustment.

8. Speaker Level Trigger Input

This input allows the unit to be activated by a audio speaker levels. The input can receive signals from 3V to 100V

AC. Wire as per the information on the box. To adjust the threshold trigger point use the Speaker Level Trigger

potentiometer adjustment. Note: This input has a high input impedance of 47 K

Ω and will not load down existing

speaker systems.

9. Speaker Level Trigger Threshold Adjustment

When using the Speaker Level input for circuit trigger activation, you can set the threshold voltage to activate the relay

trigger. The trigger range is from 3V to 45V AC. To adjust, turn the screw driver trim pot to the desired setting as per

the information on the cover.

10. Status LED

A Bi-Color Led has been incorporated to inform you when the units has power and when the trigger circuits have been

activated. RED means power is present and Green means the unit is activated.

11. Power Supply Input

The AA-PPRC was supplied with an approved UL external 12V DC supply. Plug the supply into the DC jack supplied.

12. Speaker Load

Connect these terminals to the speaker load that you are connecting or disconnecting to. Since this a two channel

unit you can use this to control two zones. You can use one channel in the “NC” and the other in the “NO” contacts if

needed. The Left and Right contacts are independent of each other as well. Note: The AA-PPRC internal contacts are

rated at 5 Amps. Please refer to the load rating chart for maximum power handling capability.
