The Trikdis RTH2 is a telephone line receiver that receives the classic telephone (PSTN) reports of alarm control panels, processes them and hands them to the monitoring software over an RS232 port. Wherever part of your accounts still report over a landline, this receiver keeps those connections alive.
It handles tone and pulse dialling lines alike, understands the most common formats – Contact ID, SIA, Ademco Express 4+2, pulse 3/1, 4/1, 4/2 – and speaks the Surgard or Radionics D6600 protocol on its output, so it fits practically any CMS software.
On request it ships preconfigured: connect the telephone line, the RS232 cable and mains power, and the receiver is ready. With a backup battery (12 V / 7 Ah) it keeps running for about 12 hours during a power failure.

Frequently asked questions
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.
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.
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.
