Alpha Communications®'s on-site UHF paging system shall have a transmitting range of up to one mile (depending on results of site survey).
The NC373 is an 8-zone on-site UHF radio paging transmitter. They will accept inputs from 8, normally closed contacts, respectively and transmit numerical messages to numeric or alpha-numeric pocket pagers. The NC373 is also equipped with a serial input that will allow the messages to be custom programmed and allow for the inputs to be changed from normally closed to normally open or change of state (volt free or voltage 5-15 volts max.). The inputs can be individually programmed so that it's state can have an effect on the other zones. The trigger time for each zone may also be changed via programming (1.3 seconds min.). All of the above programming can be done for an additional charge by ordering model number NC373CM. Qualified customers can opt to program the NC373 from any computing device that can be placed into a terminal mode, using software and hardware provided by Alpha Communications®.
Each NC373 also offers tamper inputs, monitored battery backup inputs, and an open programmable open collector output to trigger a local signaling device (1amp max.).
The range of the system will largely depend on the site and location of the base unit. The base is supplied with a 1/4 wave BNC terminated, antenna. To determine the exact range of the transmitters, a site survey must be done, contact Alpha Communications® for details. For estimation purposes of a properly located NC373, a range of up to one mile can be expected. See the instruction manual for additional details. Other antennas and signal amplification options are available to increase range, contact Alpha Communications®. Battery back-up also available.
