The time before raising the alarm by the communication loss between hub
and device is calculated with the following formula:
Ping interval * (number of undelivered packets + 1 correction packet).
The shorter ping interval (in seconds) means faster delivery of the events
between the hub and the connected devices; however, a short ping interval
reduces the battery life. At the same time, alarms are transmitted
immediately regardless of the ping interval.
We do not recommend reducing the default settings of the ping period and
interval.
Note that the interval limits the maximum number of connected devices:
Interval, sec Maximum connected devices
12 39
24 79
36 119
48 150
Regardless of settings, the hub supports 10 connected sirens maximum!
Detector Ping Interval — the frequency of connected devices polling by
the hub is setting in the range of 12 to 300 s (36 s by default)
Number of undelivered packets to determine connection failure — a
counter of undelivered packets (8 packets by default).
Service is a group of hub service settings. These are divided into 2 groups:
general settings and advanced settings.
