Parameter
„Contact period”
Each device in the system periodically sends a
status message to the Control Panel.
The parameter sets the interval between two
messages (in seconds). This time period does
not refer to the reaction of the fire detectors in fire
condition. Fire messages are sent immediately
upon reaching the criteria for fire.
This parameter has informative function for
the operator of the system and can not be
changed.
Parameter
„Response time”
When sending messages within the system,
each device expects a delivery confirmation from
the Control Panel. The parameter sets maximum
time (in seconds) for receiving confirmation. If
after several sending attempts the device does
not receive a response, it starts a new procedure
for reconnection. Increasing the parameter value
may be required for devices that are furthest from
the
Control
Panel
(they
have
4
or
5
retransmissions
of
messages
through
communicational controllers).
This parameter has informative function for
the operator of the system and can not be
changed.
Parameter
„Parent”
This parameter indicates whether the device
has saved router or control panel as a device that
communicates through the network (so-called
device’s “parent”). If parameter is set to “yes”, this
means that in cases of events: rejoining the
network, in case of complete disintegration and
restoration of the network, reboot the device or
any other reason in which detector (router) lost
regular communication with the panel. Upon
restoration of normal operating conditions, device
will search only for saved “parent”. If the device
does not detect its previous parent, falls into
sleep mode and attempting to find it periodically.
There are
2 ways to change the “parent” of
device:
-communication
mode
– just change
parameter to “no”, be sure that device receives
the command (parent value “P” will be changed
to “0”) and restart device. It will perform new
searching for ”parent” and will choose that one
to which having best radio link. “Parent”
parameter will be automatically set to “yes” after
succesfull finding of new parent.
-if device lost communication with his parent
(“Disconnected” fault is presented for this
device), but device is still battery supplied
– just
change position of the tamper detection button 5
