PIN code

Every DPH doorphone can be equipped in PIN code. By default there is no PIN code, PIN code can be used to protect DPH against unathorized access. You can define PIN code using DTMF code according table included in chapter concerning DTMF programing.

Establishing call

• To program DPH doorphone it is necessarily to establish call between PBX phone and doorphone.
• Doorphone is programmed using DTMF tones send by phone connected to doorphone.

Programing mode entering: 0987

• To enter programing mode - during established call dial: 0987^[1] (if no PIN is defined) or 0987<PIN>
• In programing mode:
  • doorphone buttons don't operate and after pressing any button reject signal (low frequency) is generated.
  • Loudspeaker is muted.

Navigation

* (asterisk) Cancel

• After pressing *, in every moment, entered parameter is canceled and program returns to XY coordinates selection.

# (hash) OK, Confirm

• After pressing # entered parameter is confirmed.
• After pressing # doorphone answers as follows:
  • confirmation signal (high frequency)
  • reject signal (low frequency) if entered parameter is improper.

Leaving programing mode 2 x * (asterisk)

• After pressing asterisk two times program mode is leaving.
• After program mode leaving connection established for programming is disconnected

Programming table

• Values in [ ] - default values
• All programmable fields are organized as XY coordinates table.

DPH programming table is as follow

Programming example

Below are presented two programming examples. Result of each example is sequence of characters that must be selected to program a specific parameter:

Programming extension number 53 as number to which phone call is directed after pressing upper button

• Establishing connection from any telephone to doorphone that we want to program
  • 0987 <PIN> - on telephone connected to doorphone - entry into programming menu
  • 01 # - enter and accept XY coordinates of parameter
  • 53 # - enter and accept target extension number
  • ** - exit from programming menu

Ultimately, entire programming string has following form:

Programming electrolock opening time for 5 seconds and microphone sensitivity as high:

• Establishing connection from any telephone to doorphone that we want to program
  • 0987 <PIN> - on telephone connected to doorphone - entry into programming menu
  • 03 # - enter and accept XY coordinates of first parameter
  • 5 # - enter and accept value ofopening time of electrolock
  • 24 # - enter and accept XY coordinates of second parameter
  • 2 # - enter and accept high sensitivity microphone
  • ** - exit from programming menu

Ultimately, entire programming string has following form:

Summary

• XY coordinates acceptation causes high frquency (OK) signal generation.
• It is possible to entering XY coordinates longer than 2 digits - only two last digits will be used.
• XY coordinates confirmation - button HASH (#)
• Parameter entering can be always canceled by STAR (*) button. as a result low frequency signal (BAD) is generated and jump to coordinates selecting
• Confirmation of any parameter can be done with HASH (#) button. If parameter value is correct and parameterr was succesfully stored in FLASH memory - high frequency signal (OK) is generated and dorphone waits for coordinates selection.
• If parameter value is incorrect - low frequency signal (BAD) is generated and dorphone waits for coordinates selection.
• Max call time - new value is obvious for next call

• For DPH.AB-KS1 short number 0 is active
• For DPH.AB-KS2 short numbers 0 (upper button) and 1 (lower button) are active
• For DPH.AB-KS1, 2RF field 05 is active (RFID cards)
• If value of STA mode option is equal to 0, active are STA control by RFID, PINu and DTMF, otherwise if value of STA mode option is set to 1, only only pressing any button or answering incoming call can trigger STA output.
• If value of option Auto answer is equal to 0, an incoming call can't be answered by doorphone. In this situation, doorphone programming is possible only after establishing call from doorphone to phone.

Adaptation of DPH acoustics to ambient conditions

Calls from DPH.AB are carried out in simplex mode - talkers must speak alternately, i.e. if person at DPH.AB speaks then person at phone listens and vice versa, if person at phone speaks then person at doorphone listens. Important are conditions in which doorphone works. Depending on the noise level, it will behave differently and you may need to adjust it, i.e. change switching threshold. Generally, if higher noise level, then higher switching threshold should be set.

Change of switching threshold:

• in doorphone set microphone sensitivity to minimum (low - 0), volume to center (3)

If doorphone is located:

• in an isolated room, the switching threshold should be set to 0
• in a quiet room - values ​​1-2,
• in rooms with normal noise - conversations, background music - 3 - 4,
• in rooms with increased noise levels - corridor, kindergarten - 5 - 6,
• in the factory hall, on the construction site, directly on the street - 7 - 8

Additional comments:

• after adaptation in case of temporary noise / noise of greater intensity than usually during normal doorphone operation, it may be necessary to speak louder to phone's handset in order to activate switching threshold.
• increasing microphone sensitivity allows you to hear person at doorphone louder but at the same time it affects level of switching threshold
• doorphone loudspeaker loudness level should generally not affect doorphone's operation, however in closed rooms or corridors one should pay attention to possibility of reverberation or echo
