DK16 HESB Installation for Electronic Tele-
phone Loud Ring Bell (Figure 7-11):
1) On the HESB TBI terminal block: connect a
jumper between Terminals 6 and 7, and con-
nect anotherjumper between Terminals 5 and
8.
2) On the HESB TB2 terminal block, connect a
jumper between Terminals 4 and 5.
NOTES:
1. HESB connections made in steps 3-6
may be accomplished using the HESB
VOICE modular jack instead of the TBI
terminal block.

4.22 Loud Ringing Bell Test. Test the Loud Ring-
ing Bell installation in accordance with the following
steps:
1) Make a CO or station call to the station config-
ured for the loud ringing bell.
l
Ringing will be heard over the HESB.
2) Adjust the HESB volume control to the desired
level. (Screwdriver adjustment on back of
HESB and ring level control of associated
telephone.)
3) If ringing is heard at the station, but not over
the HESB, perform the following check while
the station is ringing:
a)
Using a suitable voltmeter, measure volt-
age across terminals 1 (+) and 2 (-) of the
HESB TBl terminal block.
l
Voltage indication should be 4.5 -
5.0 VDC.
NOTE:
Ringing stops once the call is manually an-
swered. There shouldbe NO voltage potential
across terminals I and 2.
b) If voltage is not as specified during ring-
ing, check that the telephone wiring con-
nections to the HESB have been made
properly (wires to terminals 1 and 2 of the
HESBTBl terminal blockmay have been
reversed).
