GENERAL RULES FOR INSTALLATION
1. The indicators flash when the
handset is called, but there
is no ring.
When the handset being called
does not ring check if it in silent
Mode. If yes, please switch it over
to standard common Mode.
2. The indoor unit is unable to
monitor the entrance panel.
Check whether the first entrance
panel in the riser has been set
as the no 1 entrance panel, and
make sure that the numbers of the
entrance panels in the riser are in
sequence without repetitions.
3. Unable to monitor the Small EP.
The function for monitoring the
small EP can be only used after
installation personnel has set the
system depending on the actual
requirements. If the unit has
been set as a door bell, then the
function for monitoring the gate
EP will be disabled automatically.
4. Double click to turn Small EP
monitoring on.
When starting the small EP
monitor function make sure that
the double click interval is kept
within 800 ms (namely quick
double click on the monitor key),
or it will be considered a request
to monitor the EP.
5. How to make sure that the riser
installation is correct.
Once installing a handset, first
set its number as 101 (default ex-
factory value). The entrance panel
will now call handset 101.
If the call gets through correctly,
the normal video image will
appears, confirming that the
hardware installation and line
connection are correct (on
adjusting other handset, first
disconnect the first handset at
the 1st floor to avoid having two
handsets with the same address).
In case of more problems, please
check the configuration of
other related devices. Once the
settings have been confirmed, it
is possible to set the handset with
its actual number.
6. When the entry panel calls a
handset with a certain number,
the handset answers but there is
no voice or video signal.
If the entrance panel can call all
handsets with a number smaller
than a certain number (e.g. all
handset with number lower than
501 can be called), these handset
will answer normally. However if a
call is made to a handset with that
number or a higher number, there
is no sound on answering and no
video image is displayed. Now
confirm whether the configuration
on the riser shunt is correct. Take
out the riser shunt from the unit
system and directly connect the
EP to the floor shunt to check if it
works correctly. If it does it means
that the riser shunt is set incorrectly.
7. The entrance panel fails to call a
certain handset.
The handset number may be set
incorrectly, in which case reset
the number and try again. If the
call still fails, set the number as
101 and try again. If it is successful
it may be that the handset
household on each floor is not
the same as the #II setting on the
entrance panel. Reset this again.
If the call still fails, it may be
due to the line or other devices.
Replace the handset and check
the line. The handset will not
answer calls while in installation
setup status. Exit installation
setup status and try again.
8. The entrance panel can call the
handset normally without any
problems.
However, the internal indoor
units can’t be called through and
when answered, they can’t have a
talk.Please make sure that the set
parameters of two indoor units
are identical. if unable to ensure
that, please restore the default
parameters and reset.
9. The Small EP can’t have a
conversation with the handset
and there is no video signal.
Please disable the doorbell
function (this function is
disabled by default).
When the doorbell function is
enabled, and the small EP or the
doorbell calls in, the system will
ring but no conversation will
be possible. This is normal and
ringing will automatically stop
after 10 seconds.
