7.10 Setup Operation
The AC8’s operation features allow you to set up a rotation sequence to
alternate which devices are operating and which are placed on
Standby, as well as test devices while in Standby mode and specify
what to do when a Standby device goes into alarm as it is powered up.
You may specify delay times after an output changes state, directing
the AC8 to wait before acknowledging inputs (hold delay time) or turn-
ing an output on or off (restart delay time). With staging, you may con-
figure the AC8 to turn a standby device on or off when an analog sensor
detects a condition above or below specified levels.
