SECTION 27 53 13

CLOCK SYSTEMS

PART 1 - GENERAL

1.1 SUMMARY

A. This Section specifies a master clock and program control system including the following

components:

1. Master digital clock and program control unit.

2. Facility wide secondary clocks.

3. International Time Zone six multiclock locations (x3).

4. Program signal devices.

5. Clock circuit power boosters.

6. System wire and cable.

B. System Description

1. System shall perform the following functions:

a. Supply power to remote indicating clocks.

b. Maintain correct synchronized master clock time and transmit time-correction

signals over dedicated system wiring up to thirty two secondary clocks in parallel

and unlimited using a daisy chain method.

c. Analog Synchronous Clocks: Correct for minute- and second-hand

synchronization at least once each hour and for hour-hand synchronization at least

once each day.

d. Provide International time-zone six (6) multiclock locations (x3) synchronized to

designated international time areas. These six clocks in three separate areas (see

drawings) will be a clock feature with-in the facility.

2. Provide for manual control of programmed signal and equipment switching circuits.

3. Communicate with remote PC for access to UTC time base and to permit programming

from remote location.

4. Maintain system access security with a minimum of one level of user-access control to

restrict use of system controls to authorized personnel. Levels of access apply to both

local access and access from a remote computer. Access to user programming and control

functions is accomplished by entering a minimum three-digit code.

5. Regulate system timing functions using power-line frequency, backed up for power

outages by an internal battery-powered, crystal-controlled oscillator.

6. System shall be capable of programming multiple independent event schedules into

memory and running them simultaneously for different output circuits.

a. Quantity of Programmable Schedules: Eight minimum.

b. Number of Weekly Events That Can Be Programmed for Each Schedule: 128

minimum.

c. Simultaneous operation of independent schedules shall be limited only by the

number of signal-device and equipment-switching output circuits.

7. Daylight Savings Time Correction: Programmable for automatic correction.
