Talkback Amplified Speaker Option
The talkback amplified speaker option enables a talkback speaker to be provided in areas where a
telephone is not needed. In this configuration, the HESB is connected to the PIOU, PIOUS, or
PEPU 600 ohm (duplex) output and is used as the amplifier and speaker.
A door phone unit (MDFB) is connected to the HESB, and serves as a microphone to provide
talkback operation. (The MDFB push-button is inoperative, and the unit serves only as a
microphone for talkback and not as the normal door phone.)
Note
The PIOU, PIOUS, and PEPU 600 ohm is a two-way (duplex) page output compatible
with most commercially available talkback amplifiers – door phone not required for
talkback.

To install the HESB talkback amplified speaker
1. Connect a jumper between terminals 1 and 2 of the HESB TB1 terminal block (see
2. Connect a jumper between terminals 3 and 4 of the HESB TB2 terminal block.
3. Connect a jumper between terminals 5 and 6 of the HESB TB2 terminal block.
Note
HESB connections made in Steps 4~7 may be accomplished using the HESB VOICE and
door phone modular jack instead of the TB1 terminal block.
4. Connect terminal 7 of the HESB TB1 terminal block to Pin L1 of the MDFB.
5. Connect terminal 8 of the HESB TB1 terminal block to Pin L2 of the MDFB
6. Connect terminal 9 of the HESB TB1 terminal block to Pin 1 of the MDFB.
7. Connect terminal 10 of the HESB TB1 terminal block to Pin 2 of the MDFB.
8. If using a PIOU or PEPU, connect the PIOU or PEPU 600-ohm page output (pins 13 and 38)
to terminals 3 and 4 of the HESB TB1 terminal block.
...or
If using a PIOUS, connect the PIOUS 600-ohm page output (SPT and SPR) to terminals 3 and
4 of the HESB TB1 terminal block.
9. Set the PIOU or PEPU SW4 switch to the SPO position.
10. Connect the HACU-120’s +12V lead to terminal 1 of the HESB TB2 terminal block, and
connect the 0V lead to terminal 2.
11. Plug the provided power cord into the power supply and to a 117VAC 60Hz power source.
Important!
If AC voltage is not within range, have a qualified electrician correct the problem.

To test the talkback amplified speaker
1. Make an external page. Page will be heard over the HESB.
2. Verify that someone speaking into the door phone can be heard at the paging station. (With this
application, pressing the door phone button is not required to talk back through the door
phone.)
