CONFIGURATION 3:
LOOP START TRUNK -
In this configuration, the PCM unit supplies a 48V talk battery and loop current detection from pins 3 & 4 of the TEL LINE jack on the PCMTIM module to the loop start trunk in the telephone system.There are two modes of operation for loop start trunk.
(1) When the unit detects a loop resistance between TIP and RING, it activates.When the loop opens, the page ends. Pins 1, 2, 5 & 6 are not used in this configuration. Note: Default and VOX timers are not used in this mode.
(2)The unit will operate as in mode one, except it will also provide a
The required setup includes PCMTIM - PCMCPU - PCMZPM - PCMPS2. Modules must be assembled, from left to right, in this order.
INSTALLATION:
STEP 1: Assembling Modules PCMTIM to PCMCPU and to PCMZPM
•Follow the same procedure described previously on page 5, step 1.
Note: Do NOT connect the PCMPS2 (power supply) at this point.
STEP 2: Connecting Loop Start Trunk from the Telephone System to the PCMTIM Module
•Take the loop start trunk pair from the telephone system and wire it to the RJ11
•Use a 4 or
STEP 3: Switch Settings
•Set the
•Set the
•Set the
• Set the Talk Back DIP switches on the PCMZPM module to the OFF position (to the left) for all zones.
•Set the OUTPUT switch on the PCMZPM module to the
STEP 4: Testing your System
•Connect power supply PCMPS2 to the PCMCPU module to either the power jack 12V DC input or wire it to the 12V DC screw ter- minals observing polarity.
•Power LEDs should be lit on each module.
• Access the Loop Start Trunk from the phone system and verify access tones (double beep).
•At this point, the system should be functioning properly.
•Disconnect Power Supply.
STEP 5: Connecting the Paging Amplifier
•Follow the same procedure described previously on page 5, step 5.
STEP 6: Connecting 25/70V AC Speakers
•Follow the same procedure described previously on page 5, step 6.
STEP 7: 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 to a 1/2 turn.
• Access the Loop Start Trunk 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
•Follow the same steps for ZONES TWO (02) and THREE (03).
•Set the Bogen amplifier to the desired volume level.
