BROADCAST EMERGENCY ALARMS FROM YOUR TETRA OR MOTOTRBO NETWORK

Created 43 days ago by Mimmo Marchetti

Early warnings can be sent securely and rapidly from the scene of an incident, saving minutes and possibly lives.

Natural and man-made disasters or early alerts for refugee camps are familiar situations which humanitarians face and two-way radio continues to be extremely effective for one-to-one and one-to-many communication in such situations. So, how could this capability be extended to make it possible to broadcast mass notifications when a disaster occurs or an evacuation needs to be carried out?

Expanding the capabilities of traditional PA systems

One of the biggest challenges in disaster situations is a lack of mobile phone coverage within the affected areas. Traditional PA systems have been used to distribute mass notifications by broadcasting from desk-based microphones or through pre-recorded messages. But, what if guards and security officers were able to use their MOTOTRBO (DMR) or TETRA radios to broadcast an alarm as soon as a critical situation arises at a camp site or base? Minutes could be saved by enabling those closest to an incident to react and this can be achieved easily, today.

Motorola Solutions’ mission-critical IoT system can connect to your early warning sirens using your existing TETRA or MOTOTRBO network. The siren data and voice recordings are transported via the digital radio network to identified siren alarm locations. Not only does this allow alerts and announcements to be sent using two-way radios, it also leverages the inherent security of the digital radio network for more robust, end-to-end protection.

A customisable graphic user interface makes it easy to manage and control your sirens remotely. Activation and announcements can be made by selecting individual sirens or groups and zones and these can be programmed to send out alerts automatically, as well as enabling live broadcasts. You can also view events as they occur or store them for analysis afterwards and the system can be expanded to accommodate future growth.

Less infrastructure, lower costs, greater security

There are several ways in which our Early Warning Smart Siren solution can benefit humanitarian operations - including peace keeping missions, disaster response and development agencies:

  1. Interoperability: As the sirens can be monitored and controlled using your existing digital radio infrastructure, there is no need to set up a new communication backhaul or additional repeater sites.  The solution is also siren- vendor neutral and scalable. And for even greater reliability, redundant LTE options can be added to ensure the sirens are activated whenever needed.
  2. End-to-end security: Tone-based sirens can be easily hacked and this makes them vulnerable to misuse. False siren activations could cause havoc at humanitarian sites and even put lives at risk. By migrating your existing siren system to your TETRA/MOTOTRBO network, you can inherit the redundancy and security of the digital radio network, making your early warning system much more resilient.
  3. Cost-effective: The ability to integrate sirens from different vendors and to use your existing digital radio infrastructure keeps costs down without compromising security.

Keeping communities safer

Disasters are becoming more frequent due to more extreme weather patterns and increased threats to public safety. They’re also largely unpredictable and potentially devastating, so a robust early-warning mass notification system is critical. Providing early, clear and continuous communication during an emergency, these systems can help humanitarians to work more effectively and keep communities safer.
