In this mode, the output follows detector status. In other words, when a detector triggers an
alarm, the alarm also applies to the zone.
Example:
5.2.3 Pulse Mode (MODE3)
Following an alarm, an activation cycle begins. This cycle is made up of an “active period” and a
“disabled period”. During the “disabled period”, a new alarm does not trigger the relay. The pulse
mode has four activation times: 2, 4, 6 or 8 seconds, while the disable time is always 2 seconds.
