CHAPTER 7 • CHANNELS-ALERTS-ZONES
73
Normal channels consist of four alerts, each containing four zones. A normal channel’s
output is a logical combination of the channel’s alert, zone, delay and extend settings (see
Delay and Extend sections under Latched Channels). The normal channel’s output be-
comes active when the associated alert and zone logic, the channel delay or the channel
extend are satisfied.
Each enabled normal channel must have at least one enabled alert. If you attempt to save an
invalid channel configuration, the following message is displayed (see Figure 7.10).
Figure 7.10 – Invalid Channel Configuration
Latched Channel
Latched channels consist of two alerts (ON and OFF), each containing up to four zones
(see Figure 7.11). A latched channel, by definition, has exactly two enabled alerts that can-
not be disabled.

Figure 7.11 – Latched Channel Heirarchy
Latched channels differ from normal channels in that the channel output remains in a
given state until a contradictory alert is exclusively activated, or a maximum latch time has
expired (see Figure 7.12).
