and the same number for night mode are available. Switching between day and night
mode is automatic (based on set times) or manual (by setting the code). Night mode
is signaling by changing status of LED (1 sec on or off) in 1 min intervals. It is
possible to set two time zones.
Next feature is mobility extension function. It is possible to set calling group with two
numbers. One for analogue line (PbX number) and second for GSM network (mobile
phone number). After the pushbuttons (with this group programmed) is pressed,
system make a call trough these interfaces in the same time. First pick up answer the
call from device and second one is cancelled.
System does not dial the programmed number automatically after pressing the
pushbutton, but waits the specified time whether next pushbutton will be pressed and
only then it evaluates the code. The reason is that pushbuttons can be use as
numeric keypad for entering the code. Each code (max 5 digits) must be ended by *.
If only one pushbutton was pressed and specified time expires, system dials the
number. If called subscriber is busy, then, if pushbutton has the group of number
programmed, another number is dialed. The same procedure is executed if called
party does not answer the call in preset time - that means next number from group of
numbers is dialed. Each pushbutton press is signalized by acoustic signal. For
analog line, the call release can not be reliably evaluated and therefore the call is
ended either if preset max. time expires or door is opened or dtmf code representing
the call end is received. The door is opened, meaning relay 1 or 2 is switched on,
after receiving the set dtmf code from called party. When dial is initialized next
pressing of pushbutton is ignored. The call can be sttopped by twice speed pressing
of any pushbutton.
Max. call duration is timed. Call time overflow is signalized 4 seconds before end by
short beep (500ms). Call can be prolongated by 20 seconds if any pushbutton is
pressed.
System can to call next 100 numbers (*00, …,*99) by using table of speed dial and
pushbuttons as numeric keypad. In this case user name table (without pushbuttons)
is necessary with gsm door entry station.
In the next device status the pushbuttons have different function, device is waiting for
entering attendance type. This state is acoustic signalized. Each pushbutton can has
set one of attendance type.
3.2 Door opening
Device allows opening the door, that means switch on relay 1 or relay 2 after:
- receiving the preset DTMF code from called party
- entering the code (max. 5-digits) using device pushbuttons
- pressing the pre-programmed external pushbutton (one of 16 device pushbuttons),
e.g. at interior door side
- read of pre-programmed contactless Mifare card
- receiving of call from specified mobile phone (CLIP number)
- receiving valid code from radio remote control unit
Pre-programmed relay is switched on for set time. It can be switched off sooner,
when door is open and if door open sensing mode is used.
