Auxiliary Fault output
A single voltage free changeover contact is provided and operates on any panel fault condition. This output is
failsafe and is normally energised. When a fault occurs, the output turns off to ensure failsafe operation, or
should the system suffer a failure to all power supplies. Refer to Figure 11.
Figure 11: Typical Auxiliary Fault Output Wiring
External cables connected to the auxiliary contacts should be secured to the enclosure using metal
compression glands as shown in figure7.
3.5.6 Auxiliary Input Wiring
Four non-latching input connections are available on the fire alarm panel. The inputs are located on the loop
processor card, part number 44782-K073 at terminal block TB7. Applying a 0-volt connection to the terminal
activates the inputs. Refer to Figure 12. The inputs are provided at the following terminal numbers: -
1 External Fault Input
2 Level 2-access/inhibit override
3 Programmable Input A
4 Programmable Input B
The programmable input settings are:
!
Remote Alarm (Class Change): operates the sounders continuously (default setting for input A) or
!
Day Mode: initiates pre programmed day mode settings (default setting for input B) or
!
Isolate Outputs: inhibits the operation of pre-programmed isolation group setting
Figure 12: Typical Auxiliary Input Wiring
Cables connected directly to the auxiliary inputs should not be taken external to the control panel. Interposing
relays located within interface enclosures and mounted directly adjacent to the control panel should be used.
