CHAPTER 7  CHANNELS-ALERTS-ZONES 81

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). e normal channel’s output becomes

active when the associated alert and zone logic, the channel delay or the channel extend are

satised.

Each enabled normal channel must have at least one enabled alert. If you attempt to save an

invalid channel conguration, the following message is displayed (see Figure 7.13).

Latched Channel

Latched channels consist of two alerts (ON and OFF), each containing up to four zones (see

Figure 7.14). A latched channel, by denition, has exactly two enabled alerts that cannot be

disabled.

Latched channels dier 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 ex-

pired (see Figure 7.15).
