CONFIGURATION 10:
6 ZONES / ONE-WAY PAGING / MIXED HIGH- AND LOW-POWER ZONES / 25 & 70V AC SPEAKERS
High- and Low-Power Mixed System is a non-programmable feature that lets the system designer use a dedicated amplifier or self-am-
plified speaker per zone and at the same time use a centralized amplifier for zones requiring less than 250 watts of power*. The
PCMZPM module to be used as a low-power module must have all three zones with dedicated amplifiers or self-amplified speakers and
have its output switch set to Low-Power. The other PCMZPM module will be used as a high-power module and its output switch must
be set to High-Power. In this example, three dedicated amplifiers are used on the second PCMZPM low-power module.
Note: Low-Power Systems do not support two-way paging.
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 Telephone System Paging Output to the PCMTIM
•
Refer to paging access modes described previously in Step 2 on page 5 (paging port/contact closure), page 7 (paging port/VOX),
page 9 (loop start trunk), page 11 (ground start trunk), or page 13 (station level/Centrex). Then return to this page to complete
the following Steps.
STEP 3: 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 SYS ID switches on the PCMCPU module to the OFF position (to the left).
•
Set the TALK BACK switches on the PCMZPM module to the OFF position (to the left) for all zones.
•
Set the LO PWR / HI PWR OUTPUT switch on the first PCMZPM High-Power module to the HI PWR OUTPUT position (down).
•
Set the LO PWR / HI PWR OUTPUT switch on the second PCMZPM Low-Power module to the LO PWR OUTPUT position (up).
STEP 4: Connecting Amplifiers
•
Locate the terminals on the PCMCPU module labeled PA IN/RT and wire it to the TIP and RING (T & R) input on the amplifier.
•
Locate the terminals on the PCMCPU module labeled PA OUT/RT and wire it to the COMMON and either 25 or 70V AC output on
the amplifier.
•
Locate the terminals on the second PCMZPM module Low-Power module labeled ZONE A and connect the amplifier to the TIP and
RING terminals. Follow the same procedure for ZONE B and ZONE C.
STEP 5: Connecting 25 & 70V AC Speakers
•
Locate the terminals on the PCMZPM module labeled ZONE A. These terminals have two connections and - .
Wire your speakers for ZONE ONE to these terminals. Observe polarity (-) to common (+) to selected tap setting.
•
Follow the same procedure for the terminals labeled ZONE B for ZONE TWO, and the terminals labeled ZONE C
for ZONE THREE.
STEP 6: 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 amplifiers to the AC power outlet (120 V AC 60Hz).
•
Set the volume on your Bogen amplifiers to a 1/2 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) through SIX (06).
•
Set the Bogen amplifiers to the desired volume level.
* Older PCM systems only have a 150W capacity.
