The e2444 provides an architectural solution for a network-based Message Display/Calendar Clock/Speaker Assembly. The e2444-LD adds a programmable strobe. Combining all these components onto a single assembly offers an attractive appearance while reducing fixture and labor costs.
The e2444 uses Power-over-Ethernet technology, Just Plug It In!™ design, and a decentralized network structure to ensure easy wiring and simplified network planning. The use of Power-over-Ethernet technology allows the e2444 to be plugged into a PoE network switch to supply both power and data. The simplicity of Telecor's Just Plug It In!™ design means the e2444 does not require any network configuration or administration, eliminating IP address and DHCP server requirements. The decentralized network structure means no head end, central server or controller equipment is required to operate the network. Once plugged into the LAN with a valid time signal, the e2444 is immediately functional.
The e2444 is fully supervised and monitored for network connectivity, call destination, and call station connectivity, which is consistent with the NEMA SB-40
standard for communication systems. If the e2444’s network connection is lost, targeted e300(-MA) eConsoles will report that station as absent and display its dial number. When the e2444 is used with call stations, the call-in destinations are monitored. If the device at a call-in destination loses network connectivity, the e2444 will automatically search for an alternate destination. If no other suitable call-in destinations exist, the call station will audibly and visually indicate a fault. If a wiring fault is detected between a Call Station and the e2444, the e2444 will audibly and visually indicate the fault. eSeries devices that monitor the network for faults (for example: eConsoles, eAmplifiers, ePorts, and Visual Console for eSeries) will also report the fault.
The e2444 allows for two-way intercom communications with an eConsole. The e2444 can also be assigned to a single paging zone or multiple paging zones to receive selected paging announcements, audio programs, tuning into Public Channels, and tone signals for applications such as class or shift change.
Telecor’s eSeries technology provides extremely low-latency audio, for exceptional performance during paging and live audio playback. It also provides extremely fast all station audio connect times when performing all-call pages throughout the network. Speech is transmitted through the speaker in crystal-clear HD Audio. Audio is transmitted in the frequency range from 50 Hz to 7 kHz while using a 150 kbps of bandwidth during a call (128 kbps audio stream and overhead resulting in 150 kbps per audio channel). The maximum audio output level is 104 dB at 3.3 feet (1 m). Audio between stations and consoles is non-blocking, allowing a virtually unlimited number of audio channels across the LAN and reducing or eliminating busy signals. The microphone includes a conditioned preamp with built-in compression and noise gate for excellent vocal clarity and noise reduction.
The e2444 simultaneously displays plain text emergency or routine messages. When not displaying a message, it displays the current time and date. Hours
and minutes are displayed with large 2.25” digits. Seconds are slightly smaller for easy distinction. The date is displayed in plain text by a 10-character, dot
matrix display showing the day of the week, followed by the month and date. The date can be displayed in English, French or Spanish.
When the e2444 receives a zone distribution, the e2444 will automatically broadcast the audio announcement and a corresponding text message. Zone distributions sent to the e2444 can be manually initiated from eConsoles, from contact closures from 3rd party hardware, or from the desktop of a PC via the eCI Interface protocol. Use of the eCI Interface protocol also allows the e2444 to display text-only messages independent of any audio messages. These messages can be used to alert personnel of an emergency or situation of concern. In addition to plain text messages, the e2444 can also simultaneously display numerically-coded messages which can be activated independently to provide trained staff with additional context to the plain text messages. These can be enhanced with strobe illumination.
All e2444s on the LAN are continuously synchronized to a Time Master connected anywhere on the same network. Examples of Time Masters include: the Telecor ePort Management Interface, eCI Control Interface, eLOG Logging Interface, eSIP Interface, or a PC running the Telecor Ethernet Time Server Software. Time corrections are performed instantaneously so that all e2444s display the correct time. If communication is lost with the Time Master, the e2444s will maintain the time independently and stay synchronized with each other. Once communication with the Time Master is re-established, the display will automatically resynchronize with the Time Master.
The e2444-LD's built-in LED strobe will flash for the duration of an announcement being broadcast over the speaker and/or a message being displayed on the clock display. The strobe quickly draws attention to the announcement in progress, making this unit ideal for use in environments where high ambient noise makes announcements difficult to hear. The LED Strobe can be configured to illuminate in up to 4 colors (white, red, green or blue) with various flash patterns. Patterns can be set to activate based on defined conditions. For example, an Emergency Announcement can be assigned one flash pattern and color, while a routine announcement can be assigned another pattern with a different color.
