The On-Site Pocket Paging system shall be the Alpha Communications® / TekTone model NC371A or approved equal. It shall transmit numeric messages in a standard POCSAG format via the keypad on the system, via radio UHF of 457.525 MHz to Alpha Communications® NC397 Series Pocket Pagers at a baud rate of 512. Alpha Communications® On-Site Pocket Paging System shall have a transmitting range up to one half mup to one mile (line of sight) with a 1/2 wave dipole antenna (depending on results of site survey). System shall support up to 9,999 pagers and shall provide 2 dry contact inputs. Pagers shall have 4 different beep types and up to 12 characters can be sent to the pager.
The range of the system will largely depend on the site and location of the base unit. The base is supplied with a helical 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 NC371A, a range of up to one-half mile (line of sight) can be expected or one mile (line of sight) with a 1/2 wave dipole. See the instruction manual for additional details. Other antennas and signal amplification options are available to increase range. Contact Alpha Communications® for more details.
