Reliable communication is vital to ensure that campus staff are made of aware of upcoming events and security issues. Text messages can be sent to wireless telephones and smart phones from any networked PC, providing a discreet method of communication from the main office to the classroom. Non-emergency messages can be scheduled to appear during break times to prevent disruption to teaching sessions. Broadcast messages to teachers and administrative staff can be sent simultaneously to all members of staff or just a selected few. These can be designated as alarms or silent delivery, as required.
