Product Overview

The TimeView analog clock is an easy, affordable means of providing system-wide, synchronized time using a wireless solution.  The Spectracom wireless clock system delivers coordinated system time to all wall displays without hardwiring.  A wired model is also available.

The analog clock face is ideal for airports, hospitals, and other applications in which a traditional, 12-hour, round clock is desired.  The Spectracom analog clock combines the accuracy of a digital clock with the traditional look of an analog clock.

A typical system includes the Spectracom NetClock, a TimeBurst module, and TimeView wireless clocks.  Unlike other systems that require multiple transmitters and antennas in close proximity to the displays, Spectracom solutions use the existing conventional (non-trunked) VHF FM radio system (Model TV312V), UHF FM commercial radio system (Model TV312U), UHF FM government-band radio system (Model TV312G), or a pager system with audio input (depending on your requirements) to transmit accurate, synchronized time from the central communications system to any site in the operation.  The TimeBurst receives time from the NetClock through an RS-485 port and connects to the radio transmitter.  A user-defined schedule automatically keys the transmitter and sends a coded time-of-day digital burst.

All TimeView 312 analog clock models have internal radio receivers and included external antennas.  Each clock decodes the TimeBurst transmission and sets its internal clock to within 250 milliseconds of the NetClock's time.

The optional Event Alert features provide visible and audible alert systems.  Commands are executed using the TimeBurst Model 8185, Option 01 for Event Alert.

Spectracom solutions provide Legally Traceable Time to synchronize your critical operations.  Legally traceable time stamps provide necessary evidence of events to reduce liability risks.
