DW-IP (Wi-Fi) is designed for use both outdoors and indoors in harsh envi-ronment, with high humidity, noise, dust environments, with high content of smoke, aggressive gases and chemical matters vapors within the broad temperature range.

IP-network is used for communication between the devices based on the standard network equipment suitable for wireless access, without using of any central exchange or servers.

To communicate with other devices a wireless WiFi network is used, and the call station versions equipped with built-in Wi-Fi adapter.

Direct simplex communication with IPN1.1 devices;
Group call initiated from programmable keys and Public Address for multiple zones;
Broadcasting of alerts, alarm for single subscribers and subscribers group;
Extended voice signal bandwidth up to 6,8 kHz;
Processing of connections with higher priority;
Failure, busy, missed call and other subscribers state indication on call keys of the coupled device;
Activating of control lines in ACM-IP and ACM analogue subsystem modules;
Control of external signaling device using built-in relay;
Built-in software and configuration data for processing connections with higher priority, control of communi-cation and indication modes;
Remote configuration using IPN1.1 system administration software;
Account for connection to SIP-server as subscriber;
Built-in flash memory for storing sound fragments with a total duration of up to 3 min;
Voice communication in “half-duplex” mode between DW-IP (Wi-Fi) and SIP-devices.
