INSTALLATION RECOMMENDATIONS
STANDARD OPERATION
When the module is configured in Hub mode the device acts as a simple rebroadcaster,
in that it receives messages from the dispenser modules over the predetermined wireless
channel and then rebroadcasts them over that same wireless channel to be received by
either another hub or the gateway module.
When in Hub mode the device needs to be able to connect either directly to a Gateway or
via another Hub that has already established a valid route to a Gateway, this ensures that
the rebroadcast data can be successfully pushed through and out of the system.
The Hub module should be positioned according to the site survey to provide suitable
radio coverage, with consideration given to minimising the number of overlapping Hub
coverage zones.
Hubs are limited to a maximum of 5 rebroadcast ‘hops’ to the Gateway, as shown in
the diagram below. There are no restrictions on the number of Hubs connected to the
Gateway.
The Hub and Gateway modules should preferably be installed in locations that are secure
and not accessible by the general public. Ideal locations include maintenance closets,
electrical closets and data / communication rooms.
In all installs it is preferable for the module to be mounted as close to the ceiling as
possible, keeping potential physical contact and tampering to a minimum.
Use the alcohol wipe
provided to clean and
prepare both the wall and
hub/gateway module.
Leave to dry for 5 minutes.
Apply 2 adhesive pads to
the rear of the hub/gateway
module.
Using firm pressure mount
the module to the wall.
Hubs rebroadcast stored messages on through the system after a predetermined period
of radio silence or when the message buffer is full. (Approximately 600 messages)
