5 Default programming assignments
5.1
IDC, NAC, and relay default function types
For information on the default function types of IDCs, NACs and relays, see Table 2.
The function type of IDCs and NACs is a programmable attribute that you can manually change.
Circuit
IDC1-4
NAC1
AUX1 (Relay 1)
AUX2 (Relay 2)
AUX3 (Relay 3)
For an explanation of relay functions, see the follow points:
• RRELAY: Relay activates on general alarm; it remains on-until-reset.
• Common Trouble: Relay activates when a Trouble condition occurs; remains on-until-cleared.
• Common Supervisory: Relay activates when a Supervisory condition occurs; remains on-until-cleared.
5.2
NAC, relay, and signal circuit output mode assignments
See Table 3 for default, output, method (steady, temporal, for example) assignments for the NAC and Relay circuits.
The operating of NAC is a programmable attribute that you can manually change.
Circuit
NAC1
Relay 1 to 3
SIGNAL Modules
5.3
DACT defaults
Default NAC is enabled, the rest setting can be configured through the PC tool.
Function type
FIRE
WSO
SUPV
VSMOKE
Note: Any other trouble not specifically mentioned would have a code of 330. For example, a trouble on an output device reports an event
code of 330.
