Overview

The SPC intrusion system can be broken down into separate areas that can be used to define permissions and operation. Areas can contain zones, doors and you can define the structure to suit the needs of the building. The SPC areas can provide a range of functionality in order to enhance the security of your system. The group we are looking at in this article is Area Linking, so why would you need this? If you require that only one ATM/Vault can be open at the same time, or would like to arm a common area when all areas are armed. Linked areas provide a mechanism for the state of areas to control other areas.

Basics

Linked areas can be configured in the SPC web page, by selecting Configuration -> Areas -> edit. If the options do not appear you may not have selected commercial or financial system types. Linking can work in two ways you can perform an action on an area based on the state of other areas or you can perform an action on areas based on the state of this area. Let me give you an example, if you wanted to arm all shops when the common area is armed, then you would select "Fullset All" in the common area and select all the areas you wish to arm.

Lets look at the other options

Fullset

Fullset this area when all linked areas are Fullset.

Use Case

This can be used to arm a common area when all areas have been arrmed

Fullset All

Fullset all linked areas when this area Fullsets.

Use Case

This can be used for at the main exit to ensure all areas are armed, this will arm any areas that are not currently armed

Prevent Fullset

Prevent this area from Fullset if any linked area is not Fullset.

Use Case

This can be used for in an ATM or vault area to ensure that the area is armed, it will prevent users arming a main area and leaving the sensitive area unarmed

Prevent Fullset All

Prevent linked areas from Fullset if this area is not Fullset.

Use Case

this is a variant of the prevent fullset but it can be used in this case to affect multiple areas

Unset

Unset this area when any linked areas Unset.

Use Case

Commonly used for common areas, if anyone unsets a sub area the common area will be unset

Unset All

Unset all linked areas when this area Unsets.

Use Case

Can be used to unset a large system by unsetting all areas when an individual area is unset

Prevent Unset

Prevent this area from Unset if any linked area is Fullset

Use Case

A blocking mode, this can be used to stop a sensitive area e.g. ATM from being unset when the main premises is still full set

Prevent Unset All

Prevent linked areas from Unset if this area is Fullset.

Use Case

A blocking mode, this can be used to stop a sensitive area e.g. ATM from being unset when the main premises is still full set

Authorise Setting

Authorise Setting for linked areas

Use Case

This is used in cooperation with the dual setting procedure Setting authorisation, linking in this way will share the signal to the linked areas
