nformation about Smart Acknowledge (SmartACK)
This bi-directional communication mechanism also allows the building system to send back data to a sensor, i.e. to overwrite
SR06LCD´s set point. Smart Acknowledge requires that both communication devices do support the Smart Acknowledge
mechanism.
Repeaters are not supported, they delay in the telegram transmission. Sensor and gateway must communicate directly with each
other.
Additional Information of the used EEP´s with Smart ACK can be found using the following link:

ounting Advices
The module enclosure is prepared for direct wall mounting. For the operation a separate external 902 MHz receiving antenna is
necessary, which is included in shipment as a standard.
The antenna should be mounted at metallic objects, e.g. at an air tube behind a false ceiling or at an 7.09in. x 7.09in metal plate
(material: galvanized sheet steel, see accessories).
If possible the antenna should be mounted with a distance of > 4in. from the ceiling and from a wall. The distance to other
transmitters (e.g. GSM / DECT / wireless LAN / EnOcean sender) should be minimum 1.6ft.
The antenna should be vertically aligned downwards. The antenna cable should be wired in an electric conduit. A crushing of
cable shall be absolutely avoided. The minimal bend radius of the extension cable is 2in.
As for the cable laying the use of an active pull-up device should be avoided, in order to avoid any damages to the sheathing
respectively to the connectors.
