Installation Instructions

EkoTek System Installation and Configuration Manual Overview
When a user signals an alarm, the user identification (name), location and alarm type are
included in the alarm message displayed on the Hub and sent to Pagers.
Beacons
Beacon signals are used to update a device with information of whom its parent is. A
Repeater/Pager/Fob can only ever have one parent at a time. Every 1000ms the
Repeater transmits to the Pager/Fob, which is then updated with its location and will
continue to receive subsequent beacons from the Repeater (its parent). It will be shown
as ‘= [location name]’ on the Pager's display. As the User moves from one Repeater
towards another, they will receive a handover beacon from the Repeater being
approached. The Pager then displays ‘- [location name]’. The Pager/Fob then picks up
location information from the new Repeater and updates itself with the new location.
Two-Way Acknowledgement
For peace of mind of the User, the acceptance of an alarm at the Hub or a two-way Pager
by someone who will be going to the aid of the User, is signalled back to the User by the
Call Fob lamp and beeper changing their alert patterns.
Two-Way Radio
All EkoTek radio links are two-way, providing the ability to signal both to and from all
devices on the network.
Two-way radio provides the ability to quickly detect and correct any lost messages e.g.
when a message is relayed from one Repeater to a second Repeater, the second
Repeater will acknowledge receipt of the message. If the first Repeater does not receive
an acknowledgement, it retransmits the message. This ability allows EkoTek to function,
even in environments where there is radio interference or poor signal.
A further benefit of two-way radio is the ability to download configuration parameters to all
devices from the Hub, using over air programming. Devices do not hold their own
configuration, as this is sent by the Hub upon request, when devices are powered up.
Hence even Pagers have their configuration held at the Hub, making it unnecessary to
recall mobile devices for configuration change, as any updates are made centrally at the
Hub.
Frequency Hopping
EkoTek radio links can be configured to operate on a fixed frequency, or to hop across all
16 available frequencies. Frequency hopping increases the immunity of EkoTek systems
to radio interference. If a message is lost due to interference on a frequency, the loss is
immediately detected and the message retransmitted on the next frequency in the hopping
sequence.
Frequency hopping is especially useful where the local radio environment may be
unknown, or subject to change. EkoTek’s combination of message loss detection,
automatic message retransmission and frequency hopping, makes for a very robust radio
infrastructure.
