1.06 DESCRIPTION OF OPERATION

A. Transmitter Operation: When power is first applied to the master transmitter, the master transmitter checks for and displays the software version. The master transmitter then checks the position of the switches and stores their position in memory. The master transmitter looks for the GPS time signal. Once the master transmitter has received the GPS time, it sets its internal clock to that time. The master transmitter then starts to transmit its internal time once every second. The master transmitter updates its internal clock every time it receives valid time data from the GPS. The wireless master clock and program system shall be connected to the master clock and program system in the sound and intercommunications system for time and tone synchronization.

B. Analog Clock Operation:

1. Apply power then follow set up procedures detailed in manufacturer’s instructions.

2. After initial setup, the clock will shut off the receiver. Six times each day,

the microprocessor will activate the receiver and starting with the stored channel, it will again look for a valid time signal. If necessary, the clocks will resynchronize to the correct time.

3. If the clock has not decoded a valid time signal a pre-determined number

of days, it will go to a step mode.

C. This contractor shall furnish and install, where required, wireless repeater/transmitter(s). The number of repeater/transmitters shall be as needed for a complete, functioning wireless master clock and program system.

1.07 SYSTEM TEST AND ACCEPTANCE

A. Prior to the final site visitation, this Contractor shall conduct an operating test of the complete wireless master clock and program system. The system shall test free from grounds, shorts, and other faults. All connections shall be thoroughly checked for mechanical and electrical connections. All equipment shall be demonstrated to operate in accordance with the requirements set forth in these Specifications and as shown on the Drawings.

B. This Contractor shall perform all tests in the presence of the Architect/Engineer

and Owner. This Contractor shall furnish all personnel and test instruments for use in the test.

C. When the work on the entire wireless master clock and program system has been

completed and is ready for final review, this Contractor shall demonstrate that the requirements of the Contract as it applies to this work have been carried out and that the system has been adjusted and operated in accordance therewith.
