Revolutionary advances in digital technology have allowed us to produce the new standard for alarm announcement systems. RANS-Ultima utilizes a very short duration digital signal to produce a high-quality natural voice alarm message on portable alarm receivers, worn by roving personnel. The short duration digital radio transmission (less than 1/2 second) can be transmitted over an existing audio radio channel without interference with current radio operations.
Typical voice radio systems produce audio of poor quality when the signal strength is low. This means that if the signal fades, such as when you are in an enclosed area, the voice message is
difficult or impossible to understand. RANS-Ultima provides a natural voice alarm message independent of the radio transmission, therefore the message will always be clear and easy to understand.
Supervision of radio transmission is provided by periodic transmissions of a coded radio signal. If the supervisory transmissions are not received, the supervision lamp will flash. If the
supervision signals are not received for a preprogrammed period of time, a supervision voice message will be heard.
RANS-Ultima can be used in conjunction with your existing radio system because the RANS encoder ``listens" to your radio channel and waits for a clear channel. Duplicate transmissions of
alarm signals ensure receipt of the alarm message.
An optional output allows RANS-Ultima use with a city-wide or nation-wide paging service. Alarm messages are processed with the same speed as a digital numeric pocket pager providing the
same range and coverage.
Each RANS-Ultima portable alarm receiver features simple push button controls:
- VOLUME pushbutton: Pressing the button increases the sound level step-by-step to the maximum volume. At each step, the word ``louder" is heard indicating
the audio output level. A second press of the button decreases the sound level step-by-step to the minimum volume. The word ``softer" is heard to indicate the audio output level. The volume cannot be turned
below a minimum volume level.
