2-14Installing External Paging Output" Installing External Paging OutputThis section provides information on the installation of external devices to the external zone. A zonecan receive Trunk Audible, BGM and Paging. Speaker can be used to broadcast these signals at thezone. External page zone can be used to provide Meet-Me Paging. External zone have normally opencontacts. The relay for the zone is energized when Paging amplifier is in use, including Trunk audible andBGM (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 DHU-M1 PCB on the base unit of the Main Equipment (see "Installing the DHU-M1PCB" on page 2-12).Step 2: Connect wires from the connector on the DHU-M1 PCB labeled SPK to an amplifier for ExternalZone 1. The amplifier input must match the specifications above. Attach the speaker to your amplifier.Step 3: Connect wires from the connector on the DHU-M1 PCB labeled CTR to the device for ExternalZone 1.Step 4: Adjust the volume level of External Zone 1 with amplifier.RL2 RL1 CTR SPK DH2 DH1DHUCNRL1 CTR SPK DH2RL2 DH1CN1 CN2Paging SpeakerAmplifierSPK: External paging audio signal outputCTR: Normally open relay contacts.If a zoneis activated,the contacts close.NX8E-DHU-M1 PCB
