Installing External Paging Output
This section provides information on the installation of external devices to the external zone(s). Each
zone can receive Trunk Audible, BGM and Paging. Speakers can be used to broadcast these signals at
the zone. External page zones can be used to provide Meet-Me Paging. External zones have normally
open contacts. The relays for each zone are energized when Paging amplifiers are in use, including
Trunk audible and BGM (if programmed).
Specifications:
Output Impedance: 600 ohms
Output Level: Nominal 250 mV (-10 dBm)
Maximum Output: 400 mV RMS
Relay Contact: 1.25 amps for 24 V DC resistive loads
Step 1:
Mount the 8DHEXU-A1 PCB on the base unit of the Main Equipment (see "Installing 8DHEXU-
A1 PCB" on page 3-2-7).
Step 2:
Connect wires from the connector on the 8DHEXU-A1 PCB labeled SPK1 to an amplifier for
External Zone 1. The amplifier inputs must match the specifications above. Attach the speaker to your
amplifier.
Step 3:
Connect wires from the connector on the 8DHEXU-A1 PCB labeled CTR1 to the device for
External Zone 1.
Step 4:
Connect wires from the connector on the 8DHEXU-A1 PCB labeled SPK2 to an amplifier for
External Zone 2. The amplifier inputs must match the specifications above. Attach the speaker to your
amplifier.
Step 5:
Connect wires from the connector on the 8DHEXU-A1 PCB labeled CTR2 to the device for
External Zone 2.
Step 6:
Adjust the volume level of External Zone 1 with VR1 on the 8DHEXU-A1 PCB.
Step 7:
Adjust the volume level of External Zone 2 with VR2 on the 8DHEXU-A1 PCB.
