24CC10 Clock Controller
User-friendly front panel controls
• Controls GE two-inch or four-inch
digital clocks
• Operating modes: 12 or 24-hour clock; count down timer;
elapsed timer; score board; code blue elapsed timer
• Operates independently or as slave to master clock
• Timer display settings: hours/minutes; minutes/seconds
• Operates from 15Vdc or 24Vac
• Mounts in standard three or four-gang backbox
The GE Model 24CC10 Clock Controller is a compact, microprocessor-controlled unit that enables a GE 24D20 Two-Inch Digital
Secondary Clock or 24D40A Four-Inch Digital Secondary Clock to
be used for count up timing, count down timing, score keeping
and code blue timing. The digital clock serves as the time indicator
and display for the clock controller in the room. The digital clock is
mounted for optimum visibility, while the clock controller is mounted in a convenient location that allows access to its controls.
The Model 24CC10 Clock Controller is designed for ease of use, with
logical button groupings, intuitive labeling, and LED function guidance. When a particular operating mode is selected, related LEDs
illuminate to indicate the commands available in that mode. A lockout feature allows the front panel controls to be disabled, preventing unauthorized use. The 24CC10 and its associated digital clock
can operate as a stand-alone clock/timer or as a secondary clock
under the corrective control of a GE Model 24A715 or 24A715M
Master Time/Program Clock. The 24CC10 can also operate under
the corrective control of a StarCall®, StarCare™ or MCS350 master
clock. The 24CC10 is powered by a separate 10 to 24Vac or 10 to
15Vdc power source. The 24CC10 has five operating modes:
Clock Mode displays the time on the GE digital clock in 12- or 24hour format. In clock mode, the clock controller operates under
the control of a master clock. In the absence of a master clock, the
clock controller can operate in stand-alone mode, governing the
time for its associated GE digital clock. Stand-alone mode does not
provide battery backup for the clock display, therefore GE recommends that a master clock be used.
Count Down Timer Mode counts down to zero from a user-selected
start time. The timer can count down by minutes and hours or by
seconds and minutes. It can also be set to run silent, to beep when
the timer runs down to zero, to chirp once per minute and beep at
zero, or to chirp once per minute and once per second and beep at
zero. During the count down sequence the timer can be stopped,
restarted, and reset to its original target value.
Count Up Timer Mode measures the duration of an event. The timer
can count up by hours and minutes or by minutes and seconds. It
can also be set to run silent, to chirp once per minute, or to chirp
once per minute and once per second. During the count up sequence the timer can be stopped, restarted, and reset to the initial
timer value.
Score Board Mode uses the digital clock as a simple score board.
The two left digits of the clock display the score of team 1 and the
two right digits display the score of team 2.
Code Blue Timer Mode shows the elapsed time from when a code
blue call is placed to when the STOP button is pressed on the clock
controller. The code blue timer overrides anything currently displayed on the digital clock. This mode requires a contact closure
from a separate device that initiates code blue calls.

The Dukane Model 24D20A Two-Inch Digital Secondary Clock
provides a highly visible, even-intensity, long-life display of time
in selectable formats. It can be operated in either 12- or 24-hour
format, and at either Bright or Normal intensity levels. The time
display on the secondary clock updates to the master clock time
at one-minute intervals. This ensures that all system clocks are in
precise synchronization, and that every clock in the system is as
accurate as the master clock. The high-efficiency 24 Vac design
allows many clocks to be operated at great distances from low cost
24 Vac power supplies.

24SC12R-SPL Analog Secondary Clock
The GE Model 24SC12R-SPL Secondary Analog
Clock combines the advantages of a long-life
quartz movement with microprocessor technology to provide a round 12-inch analog clock
with contemporary styling. The 24SC12R-SPL
is a direct replacement for the GE 24SS Series
synchronous secondary analog clock. It can
also be directly connected to the wiring for GE
Model 24D20A or 24D40A digital clocks. The 24SC12R-SPL allows
the use of both analog and digital clocks on the same line and it can
emulate the correction schemes of many popular analog secondary
clocks from various manufacturers. The desired emulation mode is
selected using a simple DIP switch setting. This allows the 24SC12RSPL to be used as a replacement for failed clocks in many systems,
regardless of their original manufacturer.
The 24SC12R-SPL is designed to be flush- or surface-mounted while
requiring no special backboxes or mounting hardware. It can be
mounted as a ceiling or wall double-face clock using third-party
hardware. The Shatter Resistent 24SC12R-SPL is provided with a
single piece black metal rim with a convex acrylic lens. Clock face
time markings are Arabic numerals in a 12-hour format with black
hour and minute hands and a red second hand. This clock works
with the GE 24A715, 24A715M, MCS350, StarCall, or StarCare Master
Clocks, as well as other brands of master clocks. The 24SC12R-SPL
complies with FCC Part 15 Class A and meets the requirements for
installation in educational, institutional, and commercial sites. The
installed analog clock is ESD-hardened to IEC 801-2 standards.
