11. Operation Mode
The unit can operate in one out of two operation modes:
Automatic
or
Learning Mode
selected by:
Dip – Switch # 2
:
ON =>
AUTOMATIC MODE
or
OFF =>
LEARNING MODE
AUTOMATIC MODE:
If Automatic Mode is chosen (by Dip-Sw. # 2 => ON) then:
The unit will never answer any incoming calls except to the “ MASTER ” phone number
. If the
calling phone number is an authorized user (is one of the 1000 phone numbers programmed into the
memory) then the unit will operate the relay output in the unit according to the function chosen by the
DIP-SWITCH # 3 (Latch or Pulse) and
hang-up on the incoming call without answering it
. If the
caller is not a valid phone number, then the unit will reject the call and hang-up on the call
immediately.
LEARNING MODE:
It is inconvenient and time consuming to teach many Users’ phone numbers in to the system,
therefore, this mode was provided to enable easier way of programming big numbers of UPNs.
If “Learning Mode” is chosen (by Dip-Sw. # 2 => OFF) then:
The unit will not answer any of the incoming calls and automatically register each of the
incoming phone numbers in to the memory of the unit
and activate
the relay output in the unit
according to the function chosen by the DIP-SWITCH # 3 (Latch or Pulse).
Choose this mode to register all the UNPs in to the system in the first two-there days and then turn off
dip switch # 2 and change the operation mode to “Automatic”, so that no other numbers will be
automatically register in.
12. TRIGGER & STATUS Inputs
The unit has a negative
TRIGGER
input (the Green wire ) to activate the microphone and speaker of the
unit as an intercom system.
When the unit is triggered, the unit will announce in the speaker:
”PLEASE WAIT - YOUR CALL WILL BE ANSWERED SHORTLY”
Then, it will dial the first Phone Number and wait for an answer. If the call is not answered within 45
seconds, the GSM-18 will hang up and dial the second number programmed into the memory. The system
will try the third number and then stop. When the call is answered by one of the three first numbers, the
user can talk with the caller immediately until he hangs up.
During the time of speaking, the user (the person who answers the call) can activate the output relay
(according to the FUNCTION chosen in the unit) while pressing the
“ # “
key on his handset. The user
can activate the output relay as many times as he wishes till he hangs up.
In this mode the end user can also check the situation of the gate (open or closed) if the
STATUS
input
was connected to the gate by a magnet read switch.
To check the
STATUS
input press the
“ * ”
button on the hand set.
When the gate is close (STATUS input is “closed loop” to negative) then the unit will say “
THE GATE
IS CLOSED
”, and if this input is “open” the unit will say “
THE GATE IS OPEN
”.
In program mode the STATUS input could be checked (if it is a CLOSE LOOP or an OPEN LOOP) as
follows:
Press
* + 6 + #
=> One long beep to confirm CLOSE and two long beeps to confirm OPEN.
