Tempest 2400 Wireless Intercom System

Network Number and Lockout Key

The Network Number determines the RF frequency hopping pattern for the base station and its beltstations.

This is a key operational parameter and is represented by a number between 0 and 63.

The

Lockout Key prevents systems with the same Network Number from trying to communicate with each

other and is represented by a number between 0 and 255. Together the Network Number and Lockout

Key represent over 16,000 possible combinations to minimize the possibility of inter-system interference.

The Network Numbers and Lockout Keys for Tempest Wireless base stations are set before leaving the

factory, by incrementing by one digit. Always adjust the Network Number and Lockout Key of Tempest

base stations that are known to operate in close proximity to other base stations as described below.

Users should confirm these settings to minimize the opportunity for “mysterious” performance issues.

Failure to set a unique Network Number and Lockout Key may result in poor system performance caused

by interference from another Tempest Wireless system using the same Network Number and Lockout

Key. Because of the requirement to pair every beltstation to each base station that it will communicate

with, it is not possible to manipulate Network Numbers and Lockout Keys to gain unauthorized access to

a communication channel.

Multiple Base Stations in Close Proximity

The Network Numbers of closely located base stations should be offset by at least four, for maximum

performance. For example, on Base-A select Network Number “02”, on Base-B select Network Number

“06”, and on Base-C select Network Number “10”. In this manner each base station Network Number is

different by at least four digits. This procedure will ensure that each system is operating properly and

independently from an RF network perspective.

Also, adjust the Lockout Key on each base station. All base stations in one facility may have the same

Lockout Key if all Network Numbers are offset by four as described above, or all may be different.

Lockout keys are only differentiators for systems using the same Network Number.

The Network Number and Lockout Key settings can be adjusted from the “Radio Configuration” section of

the Tech Menu. Press the MENU button. Press the ENT button to select “base station Settings”. Rotate

the Volume control to scroll and select “Tech Menu”. Select “Radio Configuration”. Select “Network

Number”. Rotate the Volume control to adjust the value and press ENT to save.

Press MENU to escape one level and select “Lockout Key”. Adjust the value and press ENT to save.

Press MENU repeatedly to escape to the Operation screen.
