Cascading Alarm Stations

Flexibility in security

Prioritizing alarm stations is optional and applies only if many Multi alarm stations were created by your organization's Multi SA.

Purpose: cascading and priority

Your Multi system can have one or many alarm stations. With many, cascading is automatic and customizable. You can specify which alarm stations your Multi-Media units tries to reach first.

Cascade sequence

To insure against alarm station unavailability, you can:

•Assign more than one alarm station to a unit

•Set the order in which alarm stations are called.

Preparations

Before you prioritize alarm stations:

•Create Alarm stations using the Alarm Station tab. See Adding an Alarm Station: Name and Reports, p. 203.

•Set events to trigger alarms. An alarm station is ineffective until events are set to trigger alarms. See Events Defined, on p. 187.
