Voice Alarm Encoders (VAE) from Midian Electronics can have a voice message stored in them. When the emergency input is grounded the VAE will transmit an emegency ANI (i.e. MDC1200, DTMF, etc.) and the prerecorded voice message. The VAE-10 is a desktop box unit and the VAE-1 series are modules that can be wired or plugged into a two-way radio. For portable application there is the VAE-1-SM1 available in a speaker microphone.
Here are some common applications:
- Equipment Failure Notification : The input of the VAE can be connected to equipment such as tower lights or backup generator, so that when the tower light goes out it can send a voice message stating “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 a channel without need when there is an active emergency. The dispatch can have the VAE send a voice message such as “Emergency alert keep channel clear.” This message can be sent periodically until reset.
- Emergency Location and Lone Worker: The VAE 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. Such as when in a large multiple floor structure or underground. If the emergency input is activated (by a button press or the lone-worker/man-down feature) then the VAE 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 worker’s last recorded location. This enables the rescuers to concentrate their search efforts in one area of the building rather than splitting their search efforts between ten stories. Locator tones can also be generated to provide an audible alert to the searchers.
