GENERAL INFORMATION
Midian’s VAE-1 is a voice alarm encoder that can have a voice message stored in it and when the emergency
input is grounded the VAE-1 will transmit an emergency ANI and/or the prerecorded voice message. The
following are some common applications:
Emergency Location and Lone Worker: The VAE-1 is ideal for providing voice location messages for Public
Safety (firefighters and police) or for lone workers in areas where GPS location is not available. For example,
firefighters can store a custom voice message into the VAE-1 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 (by a button press or the lone-worker feature) then the VAE-1 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 the distressed
firefighter last recorded location. 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.
Equipment Failure Notification: The emergency input of the VAE-1 can be connected to equipment such as
tower lights or a backup generator, so that when the tower light goes out it can send a voice message stating that
the “Mount Lemmon tower 3 light is off”. This warning can be sent periodically multiple times or continuously until
reset. For backup power, when the backup is activated a message such as “Backup power is on”.
Emergency Alert: Public safety dispatchers do not want field radio users to talk on the channel without need
when an emergency is occurring. The dispatcher can have the VAE-1 send a voice message such as “Emergency
alert keep channel clear”. This message can be sent periodically until reset.
