Routing tab
The AK-SM utilizes an Alarm Action Matrix that allows a high
degree of exibility for various alarm routing options. At the heart
of the alarm conguration is the ‘Alarm Routing’ page, where dif-
ferent routing options can be dened, along with time delays and
alarm output stop conditions.
The central alarm action matrix allows various output options
(known as alarm actions) and alarm handling conguration to be
centrally assigned. Once the alarm action matrix has been
dened, any controller or I/O point can be given an alarm action
number. The alarm action number corresponds to the appropri-
ate output. (as dened in the alarm routing page). Alarm output
options include;
• 5 external (AK I/O) relay outputs
• Local AK-SM buzzer
• Local AK-SM front LED
• Internal alarm relay
• 2 Network connections
• 6 IP / e-mail addresses (3 per alarm receiver)
The following example can be seen as a guide to conguring your
AK-SM alarm logic options;
