æ 3-2-9 æInstalling External Paging OutputThis section provides information on the installation of external devices to the external zone(s). Eachzone can receive Trunk Audible, BGM and Paging. Speakers can be used to broadcast these signals atthe zone. External page zones can be used to provide Meet-Me Paging. External zones have normallyopen contacts. The relays for each zone are energized when Paging amplifiers are in use, includingTrunk audible and BGM (if programmed).Specifications: Output Impedance: 600 ohmsOutput Level: Nominal 250 mV (-10 dBm)Maximum Output: 400 mV RMSRelay Contact: 1.25 amps for 24 V DC resistive loadsStep 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 forExternal Zone 1. The amplifier inputs must match the specifications above. Attach the speaker to youramplifier.Step 3: Connect wires from the connector on the 8DHEXU-A1 PCB labeled CTR1 to the device forExternal Zone 1.Step 4: Connect wires from the connector on the 8DHEXU-A1 PCB labeled SPK2 to an amplifier forExternal Zone 2. The amplifier inputs must match the specifications above. Attach the speaker to youramplifier.Step 5: Connect wires from the connector on the 8DHEXU-A1 PCB labeled CTR2 to the device forExternal 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.
