Protection Inputs

This feature allows you to configure a selected input as a Protection Input. The

arm/disarm state of the protection input is not controlled by the intrusion zone,

it is not controllable from the monitoring station by manual action, and events

cannot arm or disarm the protection input. Once selected as Protection inputs,

Protection inputs are always armed; setting the input default state to disarmed

on the input configuration screen has no effect.

If a protection input becomes active, it also causes an armed intrusion zone to be

violated, and the monitored inputs that supervise the protection input will

cause the armed intrusion zone to violate if they become active (i.e., tamper,

comm fail, or supervision error of the protection input hardware will violate the

intrusion zone).

An active protection input prevents regular arming of the intrusion zone. The

journal message will indicate which input prevented arming. Force arming over

an active protection input will allow the intrusion zone to arm without affecting

the state of the protection input. However, a subsequent activation of the

protection input will cause a violation in the armed intrusion zone.

If the intrusion zone is configured with an “Intrusion zone violated” event, an

active protection input in an armed intrusion zone will activate this event.

Active protection inputs in an armed or disarmed intrusion zone activate the

“Not ready to arm” event.

An intrusion zone may have multiple protection inputs, but each protection

input may be configured as part of only one intrusion zone, not multiple

intrusion zones, and the inputs must be on the same iSTAR controller as the

protected intrusion zone. Protection inputs may be configured only for iSTAR

inputs.

Begin configuring the protection input by configuring an intrusion zone in the

system, with options as desired. On the Inputs tab, select one of the Available

inputs and in the Selected Inputs window, scroll to the right and configure it as

a protection input. Protection Inputs may be configured to activate events when

the input is active or not active as part of the normal input configuration

screens. You may configure any or all of the protection inputs to activate the

same event.
