Alarm Communicator

4G (LTE) is faster and more future-proof, since 2G networks are being phased out. For new installations, 4G is recommended; 2G is cheaper and can be an advantage where 4G coverage is weak. Many models (FLEXi SP3, G16, CG17, G17F) are available in both versions.

Traditionally via telephone line (TIP/RING) — a universal solution that lets devices communicate regardless of brand. Trikdis's own development means that panels on the supported list (and only those) can also be connected directly and digitally via serial port or data cable — as far as we know, no one else offers this, backed by 10-15 years of development.

Protegus 2 is the 2nd generation of Trikdis's cloud app: control your alarm system from your phone and get instant notifications. We recommend it for every current internet-connected Trikdis device. The user app is free; the paid, usage- (customer-) based tier is for monitoring stations, installers and companies.

Check the product page of any direct-connection communicator — e.g. E16, G16, GT, GT+, GET: if your panel's model is on the supported list, we strongly recommend that one. In every other case, choose the telephone-line (TIP/RING) version. Pick the communication type (4G / Ethernet) based on what's available on site.

The AUX power output of the Paradox SP4000 alarm panel has limited load capacity. In certain cases — whether using a dedicated or a universal TRIKDIS communicator — the communicator's current draw can place too much load on the AUX output. As a result, the communicator may become unstable, restart, or fail to operate correctly.

Experience shows that the problem is usually solved by powering the TRIKDIS communicator directly from the alarm panel's battery terminals (+/-) instead of from the AUX output. This provides a stable power supply and eliminates the restart or operational issues.

Note: Before changing the wiring, always check that the system complies with the manufacturer's specifications and that the total load on the power supply does not exceed the permitted value.

The Trikdis communicator reads the codes from the panel at start-up, so it only knows the codes that existed at that moment. If codes are changed in the Paradox panel, the Trikdis device must be restarted — for example by disconnecting and reconnecting its terminal block.

After restarting, the device reads the current codes and the new code works in the app as well.

Not for Paradox devices: Paradox's own tools, e.g. Babyware, IP150, IP180, work with a locked serial port as well. Unlocking the serial port is only needed when connecting a third-party device — such as a Trikdis communicator.

Yes. On the DSC data bus the Trikdis device plays a mostly passive, listening role. If many other devices communicate on the bus — typically keypads and expander modules — the Trikdis device may not “get a word in”: it may fail to read system data and may be unable to send control commands (such as partition arming).

The issue does not occur in every installation, but above 3–4 keypads or expander modules the likelihood increases — worth considering during the site survey.

For such cases we recommend the universal version that connects to the phone-line (TIP/RING) input: the E16T or the G16T. On the GT, GT+ and GET the connection mode can be switched inside the device, so where possible we recommend these for such installations.
