Securing the door against being open for too long is possible on 2N IP Intercoms . This feature is very useful for buildings with you have doors without handle (only with a knob) and you want to increase the security. It can be useful in banks, financial centers, offices, labs, server rooms and many others.

Just imagine that you have door lock connected to one of relays in 2N IP Intercom and also door magnetic contact. The magnetic contact is cut off when the door is open. If that takes longer than the configured time (for example 15 seconds), the 2N IP Intercom will recognize it and will trigger an alarm.

How to set it up?

  • All necessary steps for settings of this feature are shown in the figures below. You will have to configure one switch, an automation and you will also have to use one INPUT.
  • It is also required to own a GOLD license for the 2N IP Intercom.

How to configure Switch 1

  • This switch controls the OUTPUT 1 to which the door lock connected. It is set in Monostable mode which means that after activation of this switch the door is door opened for 5 seconds (it may be changed depending on your specifications).

How to configure the security feature

  • You need to enable feature Door Open Too Long Detection for the specific Switch (in our case for Switch 1) and set which INPUT is the magnetic door sensor connected to.

How to set up Automation section

  • The settings blow mean that when the 2N IP Intercom detects a logical change in the INPUT from the magnetic lock and the door will stay open for more than 60 seconds, the automation will trigger an alarm sound or any other defined action (such as sending an HTTP command, an e-mail etc.)
  • The automation can be downloaded here: Door Open Too
