Dual voltage transformer
The GE Dual-Faced Digital Clock and Speaker Housing, Model
25D750, is a compact unit with two GE digital secondary clocks
and two 8-inch (20.3 cm) loudspeaker mounting brackets. The
unit includes one 5A606 speaker with a dual-voltage impedance
matching transformer. Another speaker/transformer can be added,
if required. The unit is designed for corridors and large rooms, and
is ceiling mounted from the top housing mounting enclosure to a
backbox. The clocks are equipped with 2-inch (5.1 cm) high digital
displays with Arabic numerals. An external switch can be added
for each clock to blank the numerals in the display, if required.
The clocks are capable of displaying time in either 12- or 24-hour
format. Each 14-1/4 inch (36.2 cm) square digital clock/speaker
baffle assembly is finished in black, semi-rigid, preformed grille cloth
within an aluminum frame. Both clock/speaker baffle assemblies
are mounted on an 18-gauge steel housing with a baked-on, plati-
num white enamel finish.
Engineering Specification
The Dual-Faced Digital Clock and Speaker Housing shall be GE
Model 25D750 or an approved equal, as indicated on the plans. The
unit shall provide two GE digital secondary clocks compatible with
the GE master clock and shall provide mounting facilities for two
8-inch (20.3 cm) loudspeakers with matching transformers. One
loudspeaker/transformer shall be included, and it shall be possible
to add an additional loudspeaker/transformer.
The loudspeaker shall be an 8-inch (20.3 cm) PM seamless cone
type, GE Model 5A606 (including transformer), with a frequency

gram rating of 12 watts, and axial sensitivity of 91dB at 1 meter (3.3
feet) for 1 watt input. The speakermatching transformer shall be
dual voltage with 1/2, 1, and 2 watt taps for 25 volt operation and
1/2, 1, 2, and 4 watt taps for 70 volt operation. The speaker-match-
ing transformer shall have pigtail leads.
The clock shall be capable of displaying time in either 12- or 24-
hour format. The display shall be a 2-inch (5.1 cm) high LED unit
with Arabic numerals and shall require 15 volts DC at 0.6 amperes,
maximum power input. The terminations shall be pigtail leads. An
external switch to blank the numerals shall be added, if required.
The clock/speaker baffle assembly shall be surface finished in black,
semirigid, preformed grille cloth contained within an aluminum
frame. The clock and speaker shall be fabricated from 18-gauge
cold rolled steel, which shall be finished with baked-on, platinum
