SFCD: Federal Commander Digital System - Federal Signal

Federal Commander Digital System
The Security Key is a 16-bit code (0-65535) that is programmed into each RTU and base station
(SS2000D and SFCDWARE Computer). The RTU and base station security key must match for
successful communication. The RTU security key is programmed during initial programming of
the RTU‟s software or by performing “Update RTU Software”. If the RTU and base station
security keys do not match, a communication fail error will occur. This feature helps prevent
unauthorized system access and activation. It also prevents cross talk from a neighboring
system operating on the same RF channel. Older versions of RTU software that do not have the
Security Key feature will always communicate successfully. A key value of 65535 is defined as an
“open” system. Base stations and sirens programmed with this value will communicate with any
other siren or base station regardless of it‟s key value.
The 128-Bit Encryption Key accomplishes scrambling of the data transmission. Like the Security
Code, the 128-Bit Encryption Key is assigned to each node in the system and must be the same
for successful communication. There is no “Open” setting and the key value must always match.
A setting of zero disables encryption and should be used for compatibly with older units that do
not support 128-bit encryption.
Normally the Security Key and 128-Bit Encryption Code is set at system commissioning and not
changed again. In the rare event that it becomes necessary to change, all sirens in the system
must be updated by performing “Update RTU Software”. This change should only be done by
authorized personal. Note: Changing the Security Key or 128-Bit Encryption Code could cause
your system not to activate during an emergency.
