Wireless Digital Clock - Master Clock , Slave Clock

Overview

Our wireless synchronized master clock system operates on a very basic concept. The Master clock acquires the time and then transmits it wirelessly to the secondary or slave clocks that are in the system. The master clock is designed to receive time updates and may incorporate any one of five time receiver options. Once the transmitter master clock receives a time update, it then transmits the time to any number of secondary slave analog and/or digital clocks. The digital clocks need only a 240v ac power outlet, and the analog clocks don't need any power outlet at all. They include their own internal battery pack with 5 or 10 year life.

Each clock includes a 900 MHz transceiver that is approved for license free use in Australia. The clocks can be configured in the field to receive, transmit or repeat. The master clock can be one of the display clocks with the addition of a GPS receiver to that clock. These clocks can cover large areas indoors (up to 1,000 meter diameter), plus any slave clock can be configured to repeat the signal to extend the range even further. The clocks incorporate frequency hopping / spread spectrum (FH/SS) technology coupled with DES data encryption to be sure no one tampers with time transmissions, and are free from interference. The clocks can be configured in the field to use any one of eight channels approved for use in Australia.

From the customer's point of view, the best feature is that you will never have to adjust your digital clock again! No buttons to push, no ladders to climb - these clocks, when connected with the GPS antenna, always show accurate time. And because they have built in daylight savings adjustment, they automatically switch over at the correct time.

Benefits

• Able to synchronize all clocks throughout the entire facility using a single master clock
• All clocks not only display the same time, but the correct time as well
• Wireless clock synchronization is often more economical than wired systems
• Uses an approved licence free RF band
• Master clock automatically adjusts for Daylight Saving Time
• Eliminates inaccurate time and attendance issues (clocks are always split-second accurate)
• Provide accurate time for facility insurance and legal documents validation
• Battery backup included for high reliability operation
• Simplified installation - just hang the clock on the wall and plug it in to any 240v ac outlet
• Range of system can be increased by using repeater slave clocks, which retransmit the master clock signal
• The wireless clock system is fully expandable allowing you to start with a system that fits your immediate needs, and with the flexibility to add more devices and wireless solutions as needed
