Terminal
Important: The following procedure reinitialises the terminal
and removes the connection to the reference access point. Access
in the parameter programming procedure and set loc21 = ON (see
paragraph 4.5).
Parameter loc21 is used to return the terminal to the default confi guration
(including the supervisor address).

3.6 Wireless variables
The variables that defi ne the function of an END DEVICE in ZigBee
communication are as follows:
Minimum supervisor transmission time •
The devices (terminal and sensor), in order to ensure a battery life of at
least a few years, cannot transmit continually to the access point.
These devices are normally “sleeping” and “wake up” every ‘n’ minutes
(where ‘n’ is decided by the user based on the application).
Battery level: •
Indicates the current charge of the battery on the terminal/sensor. This
mainly depends on the time set between transmissions and the time
the keypad/display is used (terminal only).
In normal operating conditions, the following table shows the typical
battery life according to the time set between transmissions.

Tab. 3.e
Note : if the device does not communicate correctly with the
access point (problems of distance, interference,…) the battery life
may be reduced.
Wireless signal level •
This indicates the strength of the wireless signal for communication
between the terminal/sensor and the nearest access point/repeater.
-100dBm = poor signal
-30dBm = strong signal
