Snom 00007040 E303 Emergency Phone content_copy

The Snom E303 is a wall-mounted emergency telephone in traffic red colour, specifically designed for use in offices, hotel corridors, canteens, school buildings, and similar public or industrial environments. It enables quick contact in emergencies, with the connection automatically established to a predefined number (e.g. reception, emergency service, or security control room) as soon as the handset is lifted. The striking colour ensures the device is easily identifiable even in poor lighting conditions or for visitors unfamiliar with the location. The device is an IP telephone and uses the SIP protocol family for network communication. The construction is robust and solid, with a housing made of antibacterial plastic that meets hygiene requirements.

Applications

The E303 is intended for areas where rapid and reliable accessibility in emergencies is of high priority. This includes corridors, entrance areas, common rooms, canteens, schools, hotels, and public facilities. The wall mounting allows for space-saving installation that can be integrated into existing architecture. The intuitive operation and barrier-free design ensure the device can be used even under stressful conditions or by individuals without technical knowledge.

Functions and Equipment in Detail

The telephone features an automatic dial function that connects to a pre-set emergency number when the handset is lifted. Additionally, three programmable function keys are integrated, allowing direct access to other important contacts (e.g. security service, medical emergency station). The speakerphone function enables hands-free communication, with the external speaker and integrated microphone ensuring voice transmission. The device is hearing-aid compatible, facilitating use for people with hearing impairments. LED indicators provide visual signalling of status or operating conditions.

Technology Explained Simply

The Snom E303 is a corded IP telephone powered exclusively via PoE (Power over Ethernet, standard 802.3af). The device has a single LAN port (1000Base-T), which is used for both data transmission and power supply. Communication takes place via the SIP protocol, supporting one SIP account. The network connection is made via an Ethernet cable, which is included in the delivery scope.

Compatibility and Accessories

The telephone is designed for use in IP telephony networks and requires a SIP-compatible IP telephony platform or SIP proxy. Compatibility with other systems depends on SIP protocol support. The device does not include a power supply, as power is supplied exclusively via PoE. Wall mounting is done using a mounting kit included in the delivery scope.

Installation and Mounting

Mounting is done on a wall using surface-mounting technique. The mounting kit enables secure and stable installation. Installation requires connecting the telephone via an Ethernet cable to a PoE-enabled switch or a PoE injector. Configuration is done via the SIP platform, where the emergency number for automatic dialling and settings for the function keys are configured. The quick start guide included in the delivery scope supports setup.

Operational Advantages

The E303 offers a fast and reliable emergency call function, guaranteed by automatic connection when lifting the handset. The striking colour and clear operation increase the likelihood of prompt use in emergencies. PoE technology reduces installation complexity, as no additional power supply is required. The antibacterial housing supports hygiene requirements in public and industrial environments. The integrated speakerphone function and hearing-aid compatible design increase device accessibility.
