Frequently asked questions

A Security panel or Control panel is the primary controller and supervisor of a security system.

A Security panel or Control panel is the primary controller and supervisor of a security system. It is a computer that arms and disarms the security systems, communicates with each installed component, like sensors and sounds the alarm when a security zone is breached, and optionally communicates with an alarm monitoring company.

Hopefully not. Basically, the phone should be protected from any access by using a password or pattern or fingerprint. In addition, you can use password request when you start the Protegus application and also when you want remotely control something.

Hopefully not. Basically, the phone should be protected from any access by using a password or pattern or fingerprint. In addition, you can use password request when you start the Protegus application and also when you want remotely control something. At least one of them should be active, but two or three of these steps will make it pretty difficult for anyone to access your alarm system!

Yes: Protegus 2 can be tried on a live demo system, without installation or purchase — from a browser and from the mobile app too. This lets you see in advance what arming, notifications, and system status look like on a working alarm system.

There is no standalone Trikdis communicator that communicates exclusively over Wi-Fi, but the SIM-card communicators can be extended with the W485 Wi-Fi expansion module. There is also a purely Wi-Fi version, as well as a Wi-Fi + SIM 4G version, of the FLEXi SP3 alarm panel.

Protegus 2 typically retains the event list for up to two months; with a large volume of events, this period may shorten to as little as one month.

This is how the iPhone works: while an app is open, it does not receive notifications, neither sound nor vibration.

For Protegus 2 to alert you with sound and vibration, the app has to be closed. It can stay among the recently used apps, that is not a problem. But if it is fully open and you are looking at it, no notification arrives, and you only see the event in the app.

This applies to every device: the iPhone or iPad on which Protegus 2 is currently open will not alert, the others will.

Log out of your Protegus 2 account, then log back in. The app then sets the notification values again, and in most cases this solves the problem.

In addition:

  1. Always keep the app updated to the latest version.
  2. In the app's Notifications menu, switch on the “Play notifications in DND mode” slider. This way the notification plays a sound even when the phone is in Do Not Disturb (DND) mode.

On an iPhone, an open app does not receive notifications, see: Why does Protegus 2 not play a sound or vibrate on an iPhone while the app is open?
