Brigade Interfaces

Overview	The Alarm Relay Card is typically used to provide a Brigade Interface. The default
	configuration is for the three relays to operate on Fault (Trouble), Isolate (Supervisory)
	and Alarm, respectively.
	The connection drawings for the Centaur ASE, Western Australia AIU and Queensland
	PPU are included in the appendix.
Format
	These relays are normally de-energised and energise on the respective status. They have
	voltage-free contacts that are connected to two terminals and can be configured as
	normally open or normally closed by the positioning of links. Refer to Chapter 6 for
	details.
	If a normally energized relay is required to provide activation on complete loss of system
	power (Standby), the Aux Relay on the SPS can be programmed as normally on and its
	contacts connected in series/parallel with the contacts of the Fault (Trouble) relay as is
	applicable (ie series for normally closed, parallel for normally open). Where the Brigade
	interface is powered from the system power and monitored by the central station, this is
	not typically required.
	Note that the Aux relay programmed as normally energised, de-energising on Fault
	cannot be used to replace the Fault relay on the Alarm Relay Card as the latter is link
	connected to a hardware signal of “SPS CPU Fault”.
Applications
	Standard rack mounting, 3U, Brigade Interface brackets are available as follows. FZ9028
	includes the wiring loom. KT0199 requires KT0207 to provide the wiring loom with the
	encapsulated Interface (FP0740).
	Where there are space limitations, eg in the 18U cabinet, an A5 document holder
	(KT0469) can be fitted to the 3U ASE Bracket, or the 3U AIU/PPU bracket. At 220mm
	wide, this document holder is only half the width of the standard one that requires a whole
	3U trim.

	Connection for the ASE is shown in drawing 1963-62.
	Connections for the AIU and PPU are shown in drawing 1901-267 sht2.
	For the AIU (Western Australia) the links on the Alarm Relay Card are fitted for normally
	open contacts. For the PPU (Queensland) and the ASE (most other territories) the links
	are fitted for normally closed contacts.
