Alarm/Tone Generator with a Partially Active Network
Wireless GPS Time Receiver
Multiple wireless alarm/tone generators may be deployed. Each alarm/tone
generator must be located with 150 feet of a continuously active component of the
network. Open areas such as warehouse space or manufacturing facilities may
extend this range up to 330 feet.
The RC160 wireless GPS receiver will provide time updates to one or more
master clocks. The GPS translator must be located within 150 feet of one or
more RC100 master clocks (330 feet in open space construction). Each master
clock then transmits time packets to all clocks on the network. In addition, each
master clock can obtain time from public or private time servers on the network
to backup the GPS receiver. Another GPS time receiver model is able to send
time updates over the computer network to one or more master clocks. Set the
GPS receiver and master clock on different channels.
Wireless GPS Time Receiver
Ethernet GPS Time Receiver
Above is an example of a dual-redundant master clock system receiving time
updates from a single wireless GPS receiver. In addition to the time updates from
the GPS receiver, each master clock is capable of receiving redundant time
updates from local or public NTP time servers. The master clocks can be stacked
on top of one another, or they may be located in different parts of the building or
campus. Set each master clock and GPS receiver on different channels.
The RC165 Ethernet GPS receiver will provide time updates to master clocks
over the customer provided Ethernet computer network. In addition to receiving
time updates from the GPS receiver, the RC100 master clock is capable of
receiving redundant time updates from local or public NTP time servers.
Ethernet GPS Time Receiver with Redundant Masters
Using Wall Repeaters to form a Continuously Active
Network
The RC165 Ethernet GPS receiver is capable of providing time updates to
multiple master clocks located on the same subnet. Master clocks located on
different subnets should use a local or public NTP time server to obtain time
updates. The RC100 master clock is fully capable of obtaining time updates using
NTP. Set the master clocks on different channels.
Inexpensive wall repeaters are available to provide a continuously active
wireless network. This allows wireless relays, tone generators and GPS
receivers to be located anywhere in the facility where the active network is
available. The wall repeaters include an LED activity indicator to confirm that
the network is active. Repeaters are also useful to fill gaps in coverage when
wireless devices are spread far apart. Wall repeaters and analog clocks repeat all
radio channels.
