The GE Model 25F750 Digital Clock/Speaker Housing is a compact
unit with a GE digital secondary clock and a Model 5A606 Speaker
with a dual voltage impedance-matching transformer. The LED
unit is 2 in (5.1 cm) high and displays Arabic numerals. An external
switch can be added to turn the LED display on and off. The clock
shows time in either 12- or 24-hour format. The housing is 14-1/4
in (36.2 cm) high, 14-1/4 in (36.2 cm) wide, and 3 in (7.6 cm) deep,
and is constructed of black, semi-rigid, preformed grille cloth within
an off white aluminum frame. The housing is flush-mounted to a
backbox.
Engineering Specification
The Digital Clock/Speaker Housing shall be GE Model 25F750, or an
approved equal, as indicated on the plans. The unit shall provide
a GE secondary clock compatible with the GE master clock and a
Model 5A606 Speaker with an impedance-matching transformer.
The loudspeaker shall be an 8-inch (20.3 cm) PM seamless cone
type with a frequency range of 90Hz to 15,000Hz, a nominal watt-
age of 8 watts, a program rating of 12 watts, and an axial sensitivity
of 91dB at 3.3 feet (1 meter) for 1 watt input. The speaker-matching
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 opera-
tion. The transformer shall have pigtail leads.
The clock shall be capable of displaying time in 12- or 24-hour
format. The display shall be a 2-inch (5.1 cm) high LED unit with
Arabic numerals, and shall require 15Vdc at 0.3 amperes, maximum
power input. The terminations shall be pigtail leads. An external
switch shall be added to turn the LED display on and off, if required.

type with a frequency range of 90Hz to 15,000Hz, a nominal watt-
age of 8 watts, a program rating of 12 watts, and an axial sensitivity
of 91dB at 3.3 feet (1 meter) for 1 watt input. The speaker-match-
ing transformer shall be dual voltage with ½, 1, and 2 watt taps for
25-volt operation, and ½, 1, 2, and 4 watt taps for 70-volt operation.
The transformer shall have pigtail leads.
The clock/baffle assembly shall have a black, perforated steel grille
contained within a dark gray aluminum frame. The housing shall be
14-1/4 in (36.2 cm) high, 14-1/4 in (36.2 cm) wide, and 3 in (7.6 cm)
deep including the speaker. The unit shall weigh 6 pounds (2.7 kg),
