AJAX LightSwitch Jeweller User Manual page 12

Jeweller is a radio protocol for fast and reliable two-way communication
between a hub and connected devices. The protocol provides a range of
wireless radio communication between LightSwitch and the hub (or range
extender) up to 1,100 meters. This communication range allows installing
switches not only in ats or private houses but also in open spaces or large
warehouses.
Jeweller is responsible for transmitting all the necessary information and
providing instant control of any number of LightSwitch devices in the system.
Thanks to Jeweller, users can always control the light and see the current state
of switches in Ajax apps at any time.
Jeweller supports block encryption with a oating key and authentication of
devices at each communication session to prevent sabotage or device spoo ng.
The protocol involves regular polling of system devices by the hub at intervals of
12 to 300 seconds (depending on the Jeweller or Jeweller/Fibra settings) to
monitor communication with all devices and shows their statuses in the Ajax
apps.

Sending events to the monitoring station
The Ajax system can transmit events and alarms to the
app as well as the Central Monitoring Station (CMS) via SurGard (Contact ID),
SIA DC-09 (ADM-CID), ADEMCO 685, and other protocols.
Which CMSs are compatible with the Ajax system
Only events of lost connection between the switch and the hub (or range
extender) are transmitted to the CMS. No other events are sent to third-party
monitoring stations of security or monitoring companies. Use PRO Desktop to
receive all switch events on the CMS.
Temperature or current protection triggering events are not sent to PRO Desktop as
alarms.
