CONFIGURATION 11:
MICROPHONE OVERRIDE
Microphone Override is a feature that lets the system designer take priority over all paging functions and make a system-wide page
to all speakers.
In addition to the PCM modules, setup requires a Bogen VAR1 (voice-activated relay), PRS40C (12V DC power supply) and an
MBS1000A or DDU250 (desktop microphone).
The Override feature includes a quad beep pre-announce tone which can be enabled or inhibited.
INSTALLATION:
STEP 1: Assemble Modules PCMTIM to PCMCPU and to PCMZPM (see Illustration/Instructions on Appendix page 37,
then return to this page and complete the following Steps).
Note: DO NOT connect the PCMPS2 (power supply) at this point.
STEP 2: Connecting the Paging Amplifier
•
Locate the terminals on the PCMCPU module labeled PA IN/RT and wire to the TIP and Ring (T & R) input on the Bogen
paging amplifier (either TPU-Series, GS-Series, or Classic Series amplifiers).
•
Locate the terminals on the PCMCPU module labeled PA OUT/RT and wire to COMMON and either the 25 or 70V output
on the paging amplifier.
STEP 3: Connecting Optional Equipment
•
Attach a 6-pin RJ11 modular jack to the wall next to the PCM2000 unit.
•
Connect the first audio output terminal from the top of the VAR1 (right screw terminals) to the RJ11 modular jack terminal
Y (yellow). Connect the second audio output terminal from the top of the VAR1 to the N.O. contact of the VAR1. See wiring diagram
on page 24.
•
Connect the fifth screw terminal from the top of the VAR1 (see drawing) to the RJ11 modular jack terminal BK (black).
•
Connect the relay terminals (normally open contacts) from the VAR1 (two bottom right screw terminals) to the RJ11 modular jack
terminals W (white) and BL (blue).
•
Connect the MBS1000A or DDU250 microphone leads to the VAR1 (left screw terminals).
1. Connections to the MB1000A: Red to the third screw, Black to the fifth screw, and Shield to the fourth screw.
2. Connections to the DDU250: Red to the third screw, White to the fifth screw, and Shield to the fourth screw.
•
Do not use the white and green wires from the MBS1000A or the blue and black wires from the DDU250 unless you want to use
them instead of the normally open contacts on the VAR1.
•
Connect a 6-pin RJ11 modular cable between the RJ11 modular jack (previously attached to the wall next to the PCM2000)
and the Override RJ11 input on the PCMTIM module.
•
Connect the PRS40C power supply to the VAR1 (two top left screw terminals) observing polarity or use the mini-plug and connect
it into the mini-jack at the bottom.
STEP 4: Switch and Control Settings
•
Set the two slide switches on the PCMTIM to match the paging output setting from the telephone system based on the type
of interface used. See the first bullet within
STEP 3
on page 5 if using Page Port Contact Closure; page 7 for Page Port VOX;
page 9 for Loop Start Trunk; page 11 for Ground Start Trunk; or page 13 for Station Level/Centrex. Then return to this page to
complete the following Steps.
•
Set the Line/MIC switch on the VAR1 to the MIC position.
•
Set the Mic volume control on the VAR1 at 50%.
STEP 5: Testing Your System
•
Connect the power supply PCMPS2 to the PCMCPU module to either the power jack 12V DC input or wire it to the 12V DC screw
terminals observing polarity.
•
Connect the Bogen amplifier to the AC power outlet (120V AC 60Hz).
•
Set the volume on your Bogen amplifier a half turn.
•
Access the paging from the telephone system and listen (on the handset) for the confirmation tone (double beep).
•
Dial 01 to access ZONE ONE and listen (on the handset and also to the speakers) for a pre-announce tone (single beep) followed
by your page (audio).
•
Follow the same steps for ZONES TWO (02) and THREE (03).
•
Access the emergency override by pressing the talk bar on the MBS1000A or sliding the DDU250 switch.
•
You should hear a quad beep pre-announce tone followed by your all-call/emergency page.
•
Adjust the VAR1 and PCM2000 controls for optimal operation.
NOTE: You will not be able to access individual zones using the Override feature, it is for All-Call Emergency only to all zones.
