3. Installation and Operation
1) Connecting power
Connect the DC18V transformer (included, no polarity) to +/-
connectors on the rear of the master station correctly. Depress the
power switch. Year, month, day and time will display on the LCD. The
power is in normal working status.
2) Testing master station and substation
Testing master station: Depress the power switch on the panel of
master station after connecting it to power source. The master
station will start self test and test each substation one by one
from No. 1 substation. Corresponding indictor light will flash one
if the tested substation is in normal working status. And the
indicator light will lighten and keep in bright green if otherwise.
After testing all substations, the bright green indicator light will
go out after five seconds. The master station will return to normal
status automatically after testing.
3) Alarm and talk
Corresponding router indicator light of the master station will
flash in red if a substation is calling. And calling substation
number will display on the LCD, music prompt will sound and the
system will broadcast calling number. You can talk to the calling
substation by depressing corresponding router switch on the master
station, picking up microphone and substation. (Note: Master station
can talk by depressing the hands free key; Master station can listen
by releasing the hands free key. Talk from master station can be
heard by substations after 0.5 second by using hands free key for
the first time.)
4) Monitor and circular monitor
Monitor: Depress the router switch on the panel of master station to
monitor corresponding substation. Eject the router switch to cancel.
Circular monitor: Depress the monitor switch of master station in
standby status for two seconds to monitor substations circularly
(each substation will be monitored for five seconds). Depress the
monitor switch again for two seconds to cancel circular monitor.
5) Group call, all call
Select No.1-5 substations by picking up handset and depressing No. 1
router switch of master station for two seconds. Corresponding
indicator lights will lighten in green. The master station can talk
to all selected substations with handset at this time. Depress the
No. 1 router switch of master station for two seconds again to
Select No.6-10 substations by picking up handset and depressing No.
6 router switch of master station for two seconds; select No.11-15
substations by picking up handset and depressing No. 11 router
switch of master station for two seconds (by analogy). Follow above
method to cancel.
Press the broadcast key on the master station to select all
substations. The master station can talk and broadcast to all
substations by picking up handset or depressing hands free key.
6) Broadcast function
Audio signal can be input from MUSIC input port on the rear of
Depress the broadcast key. All router indicator lights of
substations will lighten in green. The master station can broadcast
or play background music at this time. “Broadcast status…” will
display on the LCD of master station. Corresponding indicator light
will lighten in red green if a substation is calling. And voice
prompt of corresponding substation number will sound.
7) Alarm output
The connectors (ARM+, 5) on the rear of master station are alarm
output port. Alarm flash light or speaker can be connected to the
alarm out put port. The alarm of substation will touch off alarm
flash light or speaker if corresponding router switch on the master
station has not been selected.
1) Contractors or Installers have the option to preset system
expiration date to ensure collection of payments.
2) Monitor can not be found by substations.
3) When powered on, if the master station can not select any
substation, check each grounding wire (No. 5 wire) of each
substation connected on the cable. If any grounding wire has nor
been connected correctly, above malfunction will happen.
