Midian's VAE-1-SM1G is a GPS / GLONASS speaker microphone that can connect to most conventional analog and trunked portable two-way radios. When the GPS / GLONASS speaker microphone is keyed it will send the PTT ID (ANI) and the GPS / GLONASS coordinates. The unit also supports sending of an Emergency ID with Location when activated by a button press, the Lone Worker feature or the Man-Down feature. Midian's CAD-800 base station controller decodes and displays the PTT ID along with the GPS / GLONASS location and other selectable information shown on a map using Google Earth or Terrain Navigator Pro with no monthly subscriber fees.
The VAE-1-SM1G also supports decode functions such as Polling, Selective Calling, Radio Disable, Radio Enable, Spy (Remote Monitoring) and Emergency Acknowledge. These decode functions are initiated from Midian's CAD-800. Polling allows the dispatcher to request a unit's GPS / GLONASS location. Selective calling can be to call an individual unit, a group of units or all units. If a unit becomes lost or stolen, it can be disabled, so it cannot interfere with the system. If the unit is later recovered the unit can be re-enabled. The Spy function enables the dispatcher to eavesdrop on a unit during an emergency or other condition. If multiple Emergency IDs are transmitted, the dispatcher can stop subsequent Emergency ID transmissions using the Emergency Acknowledge feature.
The VAE-1-SM1G can provide voice location messages for Public Safety (firefighters and police) or for lone workers in areas where GPS-GLONASS location is not available. For example, firefighters can store a custom voice message into the VAE-1-SM1G as their location changes while fighting a fire in a building. If there is a fire in a ten story apartment building and the firefighter is working on the second floor in apartment 215, the firefighter can record "Second floor apartment 215". If the firefighter moves to the third floor in apartment 306 the firefighter can rerecord the message to say "Third floor apartment 306". If the emergency input is activated then the VAE-1-SM1G will send an emergency ANI to identify to the dispatcher who is in trouble and then the voice message will follow to inform the dispatcher where the distressed firefighter is located. This enables the rescuers to concentrate their search efforts in one area of the apartment building rather than splitting their search efforts between ten stories. Locator tones can also be generated to provide an audible alert to the searchers.
