* Provides a zone page with talkback for Aiphone’s TD-H and TD-Z systems.
“Multiple paging zones with talkback may be established. A station capacity must be deducted for each talkback paging zone.
* One PD-2 adaptor suffices for talkback paging. PD-1 is not required.
* Individual volume and tone controls for background music and paging.

BEFORE YOU INSTALL AND ‘OPERATE THE EQ QUIPMEN RER
* Installation;
1. Do not attempt to install your PD-2 adaptor until you have read and thoroughly understand the installation procedure.
Requirements indicated under SPECIFICATIONS on Page 6 of this Manual must be met. Aiphone’s warranty for the
adaptor and the system is void if adaptor is installed in a manner other than described in this manual.
2. DO NOT CONNECT ANY TERMINAL ON ANY UNIT TO AC POWER LINES.
3. Select the installation locations that would not be exposed to temperature/humidity extremes, water, oil, dust, iron dust,
inflammable & chemical products, etc.
4. Be sure not to plug power supply into AC receptacle until you complete wiring connections, and unplug before opening
the unit.

5. General notes on paging equipment installation;
1) Wiring from and [A] terminals (PD-2) to BGM source and paging amplifier input;
— Use shielded wires and locate PD-2 adaptor(s) as close as possible to the amplifier and BGM source.
2) Wiringon [V][V], on PD-2;
(1) Use either 70V or 100V (or 25V in North America) constant voltage output of amplifier for speaker line and connect
paging speakers in parallel.
(2) Keep speaker line at least 50 cm (20”) away from communication line and from amplifier input line and BGM source
output line. |
If speaker line runs closely with the above lines, use a shielded single pair wires.
(3) The two speaker lines for paging speakers, directly connected to vv Vv] terminals, and talkback speakers, connect-
ed to |S] [S] terminals, must be shielded cables or kept apart from each other as much as possible.
(4) The total input of talkback speakers must not exceed SOW on either 25V, 70V or 100V line.
(5) The talkback speaker line on the PD-2 should be connected to only speakers which are required talkback,
in order to minimize the number of speakers on the line. Large number of speakers for the talkback line may deteriorate
talkback sound quality due to accumulated ambient noise from each speaker.
(6) If all speakers are connected on talkback speaker line 'S| [S] , the amplifier will have no-load in talkback mode.
Therefore, it is recommended to install some speakers for paging only on terminals or a dummy resistor
equivalent to 20 to 30% of the rated amplifier output.
(9) It is recommended that terminals be used for amplifier input.
If /PHONO! input is used, the sound quality of both paging and BGM would deteriorate due to the RIAA equalizing
circuit that is normally used in |PHONO input circuitry.
In case [PHONO] input must be used, make tone adjustment on PD-2 adaptors, taking the above into account.
(4) It is suggested that PD-2 adaptors should be installed near the center of the system, along with power supply PS-12A (or
. PS-120). |
However, PD-2 must be kept more than 20 em (87) away from PS-12A (or PS-12C) to avoid inductive noise.
* Unit selection;
1. Installation of a paging zone deducts a station capacity in TD-H or TD-Z systems.
2 If talkback is required, select a PD-2 adaptor. PD-1 adaptor is not required.
* Operation;
1. On TD-H station, do not depress more than one number buttons each assigned for paging zone.
2. Do not depress number buttons for (talkback) paging zone and communication simultaneously. It may cause an incom-
plete paging announcement to be and high-pitched noise to come out from the speakers.

(2) WALL-MOUNTING INSTALLATION;
PD-2 is shipped with the mounting bracket. Attach the mounting bracket
to single-gang box or to wall/rack, with the supplied screws. Insert the
prongs of the bracket into the holes on back of the adaptor and pull the
body downward. PD-2 MOUNTING SINGLE-GANG

(3) PAGING SPEAKERS INPEDANCE-MATCHING;
* Determine the number of the speakers and output power for each so that the total of required power for the speakers will be
equal or less than the rated output power of the amplifier.
*Impedance matching table (Example);

(4) ADJUSTING CONTROLS;
Upon completing all the wiring connections, proceed with the following steps before turning the system on.
I.
. Set also TALKBACK VOLUME & NOISE controls at MIDPOINT,
. Turn on power supply PS-12A (or PS-12C) of TD-H or TD-Z system, paging amplifier & BGM source.
wn о‘
Set PD-2 adaptor VOLUME, TREBLE & BASS controls (and of paging amplifier and BGM source, if included) at MIDPOINT.
. Initiate paging or talkback operations (prior to BGM control adjustment).
. Adjust paging VOLUME control on PD-2 to achieve desired level. Fine tune paging TREBLE & BASS controls on PD-2. In
places where a TD-H/TD-Z station is located near the paging speakers, feedback might take place if the paging volume is too
high.
. By PD-2 noise control, tune out or reduce interference on talkback only created by line induction and then adjust talkback
volume.
NOTE: When adjusting talkback level we recommend having a radio playing or an assistant available in the talkback paging
zone to facilitate proper volume adjustments.
. Adjust PD-2 background music VOLUME control to achieve desired background music level.
Fine tune background music TREBLE & BASS, while listening to the background music. Adjust background music VOL-
UME, TREBLE & BASS controls on BGM source, if included.
