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

Just imagine that you have door´s lock connected to one of relays in 2N® IP intercom and also door magnetic contact. The magnetic contact is cut off when door is open. If that takes too long over configured time (for example over 15 seconds) 2N® IP intercom will recognize it as too long for doors to be open and will trigger an alarm!

How to set it?

All necessary steps for settings of this feature are shown in the figures below. You will have to configure one switch, automation and you will also have to use one input.

You will also need to order two licenses for 2N® IP Intercom:

  1. Enhanced integration license (order number: 9137907) - this license is necessary for settings of all automation commands

You will need to use firmware 2.24 or newer in 2N® IP intercom.

How to configure Switch 1

This switch controls the Output 1 to which is door´s lock connected. It is set in mono stable mode which means that after activation of this switch there will be door opened for 60 seconds (it may be changed depending on your specifications).

 

 

How to configure security feature Door Open Too Long Detection

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


How to set Automation section

This automation can be download here:Door Open Too Long.am 

The settings above mean that if 2N® IP Intercom detects logical change in the input from magnetic lock, and if door will not be closed in 60 seconds, automation will start alarm sound, or can do other stuff such as send HTTP command to security desk, send an email etc...

Note: All commands used in the Automation section are deeply described in our 2N® IP Intercom Automation manual where are also some examples. This manual is available on our web pages:
