10. On connecting the Apartment
interface, the handset’s own
number won’t be the same as the
one previously set.
On connecting an apartment
interface, the handset will
automatically detect the
connection and change its own
number to 101. The handset will
automatically use the number set
by the apartment interface.
11.
On being powered, the handset
will send the SOS to the
Switchboard.
SOS switch type is different from
the setting type.
Default setting SOS type is NO
(Normally Open).
12. The alarm handset cannot
be armed.
If the alarm handset cannot be
armed, it may be due to the
following:
„
„ the probe type is incorrectly set.
For example, the normally closed
type is set as normally open;
„
„ the probe is not connected or not
correctly set. First ensure that the
probe is correctly connected to
hardware, and then open software
setup to enable it. There is an
overcurrent on the alarm probe
and it cannot be guarded until
repowered after 10 seconds.
13. The handset is unable to start the
Small EP monitoring function.
„
„ IU be set as Slave
Only the master handset can
monitor the Small EP.
„
„ IU enable door bell function
If the handset starts the doorbell
function, it will automatically
close down the small EP.
14. The handset is unable to set the
household number
When the handset is connected
with an Apartment interface, the
household number cannot be set.
When the last two digits of the
household number are higher
than the number of users (#II) on
each floor, the household number
cannot be set. For example, if
the handset is programmed for
one-riser two-households on each
floor, then it will be illegal to set
the household number as 203.
15.
Some parameters cannot be set.
Some parameter settings in the
handset rely on other parameter
settings, namely they have
an interlocking relation. If the
doorbell function is enabled, Small
EP monitoring cannot start.
When unclear about which
parameter is incorrect, it is
recommended to reset the default
parameters and start again.
Note: after the default parameter has been
restored, all the other parameters will be
restored to the ex-factory value.
16. The alarm indicators or the
zone indicators are always on
irrespective of the status:
This results from the overcurrent
of the alarm probe powered by
the handset which automatically
causes a protection status.
Disconnect the power after 10
seconds to eliminate the fault.
17.
When the Small EP calls in, the
handset returns to the idle Mode
immediately:
This is the result of a short-circuit
on the Small EP. Please eliminate
the problem and then reconnect.
18.
The secondary EP can call the
handset normally, but when
the main EP calls the handset,
conversation is possible but there
is no video signal.
Make sure that main EP is
connected to system out port of
riser shunt.
