This category brings together programmable devices for building automatic security-announcement systems and scheduled paging. These devices handle the automatic playback of pre-recorded messages triggered by external systems (a panic button, access control, an intruder alarm, CCTV) or by a programmed schedule (school bells, store-closing announcements, regular information messages).
The VPA-ANT 8P is a programmable trigger MP3 player for public address and announcement systems. It uses positive trigger logic (+V to input), with 7 trigger inputs, 8 MB of flash memory, and USB and microSD support up to 32 GB. A built-in 10 W Class D amplifier, RS485 control and a 3.5 mm line output round out the unit.
The VPA-ANT 8N is a programmable trigger MP3 player for public address and announcement systems. It uses negative trigger logic (short to GND), with 7 trigger inputs, 8 MB of flash memory, and USB and microSD support up to 32 GB. A built-in 10 W Class D amplifier, RS485 control and a 3.5 mm line output round out the unit.
The VPA-Timer is a multi-zone controller-player for background music and public address systems. It manages 6 broadcast zones with independent source switching, a built-in media player (USB/Bluetooth/FM) and a priority microphone input.
The VPA-ANT 8P and VPA-ANT 8N units are installed in announcement cabinets and are triggered by a command from a panic button or a security system, automatically playing a pre-recorded message about evacuation, a security threat or another emergency. The VPA-Timer controller additionally supports a programmable schedule — it sets daily automatic playback at the required times across the selected zones. All devices integrate with VPA systems and are compatible with standard security relay outputs.
As security requirements for public venues and mass-gathering sites have tightened in recent years, automatic voice-announcement systems have become a mandatory part of the safety infrastructure of shopping centres, schools, educational institutions, sports venues and public spaces. The ANT line and the VPA-Timer are designed with these requirements in mind.
