The SONIA UTS is a range omnidirectional/directional electronic sirens produced since 2004 by Axatel Service, an outdoor/indoor notification firm based in Romania. Working in tandem alongside Axatel's SONIA software, the SONIA UTS is a popular choice in Romania and competes regionally with the well-established Telegrafia PAVIAN.

Design

The SONIA UTS utilizes a varying number of thin rectangular horns with a triangular side-profile made of aluminum alloy. 150 W

An omnidirectionally configured SONIA UTS1200.

drivers for each horn power the siren, with cube-shaped enclosures shielding each driver from the elements. The design of the horns and drivers are sourced from HÖRMANN's ECN, as its speaker design is very efficient and extremely influential as a result of the design being licensed to other manufacturers (or in some cases copied). The minimum number of speakers the SONIA UTS supports are 4 (600 W), and the maximum is 16 (2400 W). The speakers attach to a galvanized steel pole which the speakers attach to via a side mount and can be configured in a variety of ways; in most cases, they are arranged in a way where the sound is propagated omnidirectionally, with the principle being based on gap diffraction (also called Huygens' principle).

The SONIA UTS sirens run on 230 V AC/12 V DC, powered by 2 rechargeable lead acid batteries, and utilizes 1 Class D amplifiers depending on the number of speakers used. Axatel's SONIA software, of which these sirens are integrated with, allows for remote activation of the sirens, the monitoring of unauthorized access to the control panel, seismic, chemical, and weather activity near each siren site, and live audio to be broadcasted through the sirens. An optional weather station able to be installed alongside a SONIA UTS unit, consisting of a temperature, wind, and humidity sensor, is able to provide weather forecasts viewable through the SONIA software. Each siren communicates with SONIA by either GSM mobile telephony, ethernet TCP/IP protocol networks, a dedicated telephone line, or a dedicated VHF/UHF radio frequency. The sirens are able to be disconnected from electricity via the software whenever necessary, and the status of a siren's power supply, drivers, amplifier, and batteries are also able to be monitored.

These sirens are able to run for at least 2 minutes 10 days after it has been disconncted from its power supply. All of the SONIA UTS's control components are housed in a square IP55 weather resistant enclosure (although SONIA UTS1200/2400 units have slightly longer rectangular enclosures to make up for additional equipment). The SONIA UTS's output, as rated by Axatel, is 109 to 121 dBa at 30 m (100 ft). The sirens are audible at 70 dBa for at least 5.2 km2 (2 sq mi)/1300 m (0.8 mi) to 12.6 km2 (4.8 sq mi)/2000 m (1.2 mi) and have an operating temperature range of -30°C to +75°C.
