Sleeping Mode
SGZB02I is designed to go into sleeping mode for power-saving in some situations:
A.
When it doesn’t find a network to join → SGZB02I will go to sleeping mode.
B.
While the device is in the network → the sleeping period is 5 minutes; it will wake up every 5
minutes to keep online.
C.
Once SGZB02I was joined to a network and by any chance the network is no longer existed or the
device is out of the network → SGZB02I will wake up every 15 minutes to find the network it
joined before. It never keeps in sleeping mode and continues to find its network every 15 minutes.
This condition would consume up to 30 times power spending compared to normal-operating status.
To prevent this unwanted power consumption, we recommend that users manually power off the
device.

HeartBeat Technique
In a security system, it is important that Zone devices report the conditions to the central security unit (the
CIE device). To meet this need, ISysmart came up with a technique called “
HeartBeat
”.
Right after SGZB02I enrolls to a security system, it sends a HeartBeat signal to the CIE device. Afterward, it
will send HeartBeat data every hour by default settings.

Battery
Low-power report: When the operating voltage is lower than 2.4V, SGZB02I will send a low-power report to the
CIE device.
The related data:
Power configuration cluster (ID:0x0001)
Battery voltage attribute (ID:0x0020)
