7.3 Description of the motherboard terminals
The numbers in square brackets in this section will help you to identify the components on the
motherboard (see Figure 27).
7.3.1 Terminals
Figure 27 - Terminals
AUX terminals: 24 V output for external loads protected by resettable 1.8A fuse [23]
AUXR terminals:24 V output for external loads protected by resettable fuse 1.8A (with “power cutoff”
during reset) [24]
PL Terminal [22] (comprises terminals PL and GND). PL closes to GND in the event of control panel
shutdown.
RS 485 BUS for the Repeater connections (up to 8) [25]
ALARM relay (dry contact) [26]
FAULT relay (dry contact) [27]
Supervised FAULT NAC output protected by 1 A fuse [28]
Supervised ALARM NAC output protected by 1 A fuse [30]
Supervised, programmable NAC Outputs (NAC1, NAC2, and NAC3) protected by 1 A fuse [31]
Loop 2 In/Out terminals [32] (6 terminals, 3 Input terminals and 3 Output terminals)
Loop 1 In/Out terminals [33] (6 terminals, 3 Input terminals and 3 Output terminals)
7.4 Loop Connections
The loops accommodate a vast array of fire system devices (detectors, manual callpoints, fire buttons,
Input and Output modules, etc.).
For a detailed description of the devices the Loop accepts, refer to Appendix B.
Due to electrical incompatibility (refer to Appendix B), different brand devices (i.e. devices using
different protocols) cannot co-exist on the same loop. However, the loops can be programmed
separately in such way as to allow the system to manage different brand devices on different loops.
