Hands-Free Intercom
The SC-WR04E weather-resistant outdoor emergency phone is ideal for deployment in high-noise settings including steel plants, tunnels, ports, residential complexes, schools, and transportation stations.
Description
Brief Introduction
The SC-WR04E hands free intercom is a weather-resistant emergency communication phone designed for locations where users need to make or receive calls without handling a traditional handset. Its wall-mounted design, aluminum alloy enclosure, IP66 protection, and one-touch calling function make it suitable for demanding outdoor and industrial environments.
The unit can be configured for SIP, analog, or direct fiber optic communication, allowing it to work with different communication infrastructures. It also supports automatic answering, preset speed-dial numbers, multiple SIP accounts, and hands-free audio communication.
SC-WR04E is suitable for steel plants, tunnels, ports, residential complexes, schools, transportation stations, and other public or industrial areas where reliable emergency communication is required.
Product Features
One-Touch Calling
The SC-WR04E allows designated telephone numbers to be programmed in advance. The user can initiate a call by pressing the corresponding call button, eliminating the need to enter a complete telephone number during an emergency.
Automatic Answering
The device can be configured to answer incoming calls automatically. This allows the remote operator to establish communication with the installed unit without requiring someone to physically operate the telephone.
Multiple SIP Accounts
For IP-based installations, up to three SIP accounts can be configured. The accounts can be switched according to the communication setup, providing an additional option for projects that require multiple SIP connections.
IP Address Reporting
During configuration, pressing and holding the hands-free button for approximately 10 seconds can trigger automatic reporting of the device's IP address. This simplifies device identification during network commissioning.
Hotline and Speed Dial
Hotline and speed-dial functions can be configured for projects where the intercom needs to contact a fixed destination rather than allowing users to enter numbers manually.
