 The supplementary alerting service app or SAS makes turning out to fires and emergencies easier. With the SAS you'll get timely, accurate and relevant information directly from the emergency alerting system to your smart device. Set your availability for turnouts and chat with fellow members. Indicate if you're responding to a fire call. See who from your brigade is turning out to fire calls, their expected response time and what skills those responding members have such as driver, crew leader or BA wearer. Experience one touch navigation to your station or an incident. The supplementary alerting service app has been developed by CFA, SES, Ambulance Victoria and ESTA in conjunction with Emergency Management Victoria. It is the only app endorsed for use by CFA members. Download the supplementary alerting service app today.
