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. 
 
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”. 
 
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.
