11. Startup Procedure for a Dual
Safety System
11.1 Introduction
This chapter describes the initial startup procedure of a system
consisting of a Primary System and a Secondary System (AutroSafe
Dual Safety concept).
In principle, the startup procedure is identical to the startup procedure
of a normal system, however, the startup procedure must be carried
out for each system in turn (both the Primary System and the
Secondary System).
The startup of the Primary System can take place from any selected
Fire Alarm Control Panel BS-420 or Operator Panel BS-430 belonging
to the Primary System. Likewise, the startup of a Secondary System
can take place from any panel belonging to the Secondary System.
There are two AutroKeepers BN-180 for each detection loop in a Dual
Safety System. One must be assigned to the Primary System and the
other to the Secondary System (dipswitch settings). Furthermore, the
type of protocol for the AutroFieldBus Protocol Converter BSD-321 (if
used) must be set to Al_Com+ (rotary switch setting).
In the following guidelines, a startup of the Secondary System is
carried out first, then the Primary System. When the startup of both
systems is completed, the Primary System will be in Active Mode (it
controls the detecton loops), and the Secondary System will be in
Standby Mode (ready to take over control of the detection loops).
