13.8 Provisioning External Alarms and Controls

External alarm inputs can be provisioned on the Alarm Interface Controller-Inter national (AIC-I) card

for external sensors such as an open door and flood sensors, te mperature sensors, and other

environmental conditions. External control outputs on this card allow you to drive external visual or

audible devices such as bells and lights. They can control other devices such as generators, he aters, and

fans.

You provision external alarms in the AIC-I card view Provisioning > Card > External Alarms tab.

Provision controls in the AIC-I card view Provisioning > Card > External Controls tab. Up to 16 external

alarm inputs and 4 external controls are available with the AIC-I card.

You can provision each alarm input separately. Provisionable characteristics of external ala rm inputs

include:

•Alarm type, from a list of possibilities in a drop-down list

•Alarm severity (CR, MJ, MN, NA, and NR)

•Alarm-trigger setting (open or closed): Open means that the norm al condition is no current flowing

through the contact, and the alarm is generated when current does flow; closed means that normal

condition is to have current flowing through the contact, and the ala rm is generated with current

stops flowing.

•Virtual wire associated with the alarm

•CTC alarm log description (up to 63 characters)

Note If you provision an external alarm to raise upon an open contact before you physically connect

to the ONS equipment, the alarm will raise until you do create the physical connec tion.

Note When you provision an external alarm, the alarm object is ENV-IN-nn. The variable nn refers to

the external alarm’s number, regardless of the name you assign.

You can provision each alarm output separately. Provisionable characteristics of alarm outputs include:

•Control type

•Trigger type (alarm or virtual wire)

•Description for CTC display

•Closure setting (manually or by trigger). If you provision the outpu t closure to be triggered, the

following characteristics can be used as triggers:

–

Local NE alarm severity—A chosen alarm severity (for example, Major) and any

higher-severity alarm (in this case, Critical) causes output closure.

–

Remote NE alarm severity—Similar to local NE alarm severity trigger setting, but applies to

remote alarms.
