Installation Guide SMX-AUS

3.4 Notification Appliance Circuits (On-Board NACs)

• Notification circuits are supervised, power limited, Class B wires, which may be connected to energy-limited cable.
• Only the compatible, Notification Appliances that are listed in Device Compatibility Document are recommended.
•
Wire Notification Appliances according to the manufacturer's instructions packaged with each device.
•
The On-Board NAC1 output current is 500 mA for regulated NACs.
• The On-Board NAC2 is for DA30/60 OWS (CIE + & CIE -)output current is 500 mA for special application NACs.
• Add the resistor (R21-0036-000) 10K EOLR at the end of the device.
To identify the NAC interface, refer to Fig. 1, "The Main PCB Layout".
THE NAC SHOULD NOT BE CONNECTED TO THE POWER SUPPLY AT ANY TIME. CONNECTING TO A POWER SUPPLY DAMAGES THE COMPONENT.

3.5 Auxiliary Relay Outputs

The Fire Alarm Control Panels have three, unsupervised, relay outputs, with volt-free (dry contact) changeover contacts. These are assigned to Fault, Fire Alarm, and
Programmable conditions, respectively.
Fire, Fault and Programming output are rated at 24 V AC / DC, 1 Amp. This rating is applicable for special applications filtered DC.
Connect the screen drain wire to the nearest earthing point in the enclosure. The panel provides the following set of Auxiliary Relay Outputs:
•
Fire relay
•
Fault relay  is normally held in an energized state. It will de-energize under fault conditions.
•
Programmable relay  By default it is configured for supervisory state. Programmable relay is configurable between supervisory state or programmable relay (user
programmable conditions.)
AS 7240.2: 8.6 SUPERVISORY SIGNAL CONDITION OUTPUT
NOTE THAT FOR COMPLIANCE, THE INSTALLER MUST ENSURE THAT THE PROGRAMMABLE RELAY IS CONFIGURED AS A COMMON SUPERVISORY
OUTPUT, IF THE FIRE ALARM CONTROL PANEL IS CONFIGURED TO MONITOR SUPERVISORY CONDITIONS.
The relays are non-power limited and need separate conduit wiring.

3.6 Auxiliary Supply Outputs

The Fire Alarm Control Panels have two power-limited, unsupervised auxiliary output power supplies - AUX1 (500 mA) and AUX3 (3.5 A).
•
AUX1 can be used for powering ARE / ASE.
•
AUX3 can be used for OWS DA 30 / 60.
