Trikdis UHF antenna T16U communicator

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.

The radio communicator (T16U UHF / T16V VHF) signals on its own radio frequency to a dedicated receiver station — ideal where there's no reliable mobile network or internet. GSM/IP communicators signal over the mobile network or internet to a monitoring station or to Protegus.

Yes, using the TrikdisConfig programming software (via USB or remotely). The latest firmware is recommended for the best compatibility and security.

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.

Currently the FLEXi SP3, the CG17, and the GV17 support SMS forwarding; this feature is not yet available on the other devices.

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.

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.
