A free program for Android, by Kendall Martin.
KM-911-Alert is an application that sends alerts to your phone for any station in the Lebanon County Fire and Emergency Services. It allows you to receive alerts for the most important stations, such as those that respond to emergencies or patrol the city.
It works as follows: when you open the app, it automatically detects the Android device you are using and the region you are in. Then, you can select the station you want to receive alerts for. It is possible to receive alerts for more than one station simultaneously.
This application is not a replacement for a pager. It is a notification service.
