Silent alarm is one of many new features that can be configured in 2N IP Intercoms thanks to the “Automation” feature. This feature is very useful in areas where you could face a dangerous situation – e.g. a thief forces you to open the vault door. This situation can occur mainly in casinos, financial centers, banks, etc. For such cases you can specify an unique code which will be used for opening the door but simultaneously it will trigger another action such as: sending an HTTP command for alarm activation, establishing a call, etc. The most common scenario is that 2N IP Intercom sends an HTTP command to another device. The device processes the command and triggers an alarm in the security room.

How to set up Silent alarm on 2N IP Intercom

  • The settings below mean that if anybody wants to unlock the Switch 1 in a standard way he just enters the code 1234 and confirms it with the wildcard (*) button. This setting can be specified directly in the Switch 1 section and it is not necessary to do it in Automation section. But once you will feel threatened, you can enter the code 1235 and confirm it with wildcard (*). In this case you will activate Switch 1 (open the door) and simultaneously you will send an HTTP request to another device with the IP address where you activate the alarm (this device has to accept the HTTP request, process it and do the appropriate action). A thief doesn't know anything about this second action and you can expect that someone will come to help you. Make sure you don't have anyone else pick this alarm code as a PIN code.
