## Long description

Outdoor siren Evolveo Alarmex/Sonix ACS OTS is an external audible and visual signaling device for security systems.

The siren includes tamper protection and a backup battery to maintain operation during mains failure.
Advantages
The siren is easy to pair with the main Alarmex control unit and can also be connected to Evolveo Sonix systems.

The unit is powered by a universal adapter (100–240 V AC / 12 V DC, 500 mA) and includes a 7.2 V backup battery for continued operation during power outages.
