Network PA System – 32‑Channel Network Alarm Host (2U, Linux, 32 Inputs / 33 Outputs)
1. Product Function Description:
1. High‑end aluminum 2U black brushed panel, beautiful and elegant.
2. The embedded digital network broadcasting module software is used in conjunction with it.
3. Using domestic chips and Linux system, with stable performance and fast operation.
4. 32 network alarm inputs: when there is a signal input, the corresponding channel indicator lights up.
★ 5. 32+1 network alarm output, low‑level closing signal, easy to control other devices.
6. Alarm signal priority, automatic forced insertion.
★ 7. Supports switching between fully open and fully closed modes.
8. Corresponding alarm ringtones can be set according to different locations and alarm sources to make the disaster situation clear and bright.
9. Support manual and automatic alarm functions.
10. Support N ± 0 ~ N ± 4 neighbor layer alarm function.
11. Automatically send alarm information to the server and perform playback tasks (supporting neighboring layer/whole area alarms).
12. Intelligent interface for fire alarm and emergency alarm signal function.
13. The alarm sound file is pre‑stored in the server and does not require an external alarm sound source.
14. 32 partitions are automatically activated and can be expanded to unlimited partitions at will.
15. Supports DHCP, compatible with routers, switches, bridge gateways, Internet, multicast, unicast, and any network structure.
