The agocontrol security system is implemented in the "agosecurity" component. It provides a "securitycontroller" device to the system. This is used to interface with the security system, like changing the house mode, cancelling an alarm and triggering zones.
There is no fixed assignment of sensors into zones, like in other systems. In agocontrol you trigger a zone by sending the command "triggerzone" to the securitycontroller device. It takes a "zone" parameter. Usually this command is sent from an action in an event handler. This gives endless possibilities, as you can use arbitrary criteria in your events.
Different housemodes define the state of zones. A zone can be either "inactive", or be set to a specific delay value in seconds per housemode.
The countdown start will be announced with an event, and a follow-up event will be sent every second with the remaining time. If the countdown is not cancelled, an alarm event will be sent. An event handler can be used to take action, like firing an alarm scenario (switching on a siren, sending SMS, turning on the lights, ...)
