7.10.4Specify Hold Delay Time

After an output changes state, the hold delay timer directs the AC8 to ignore all inputs in the same zone for the specified time.

This delay is the amount of time that must elapse before the AC8 acknowledges a change of state in any input. The default is 10 minutes (displayed as 10 MIN : 00 SEC).

The time delay applies only when a monitored output device changes from its normal state—for example, the AC8 detects a closed contact that is defined as Normally Open.

When the output device returns to its normal state, the AC8 acknowl- edges any input change of state immediately.

The hold delay timer also takes effect when the AC8 is powered up. All alarms are ignored until the hold delay time expires.

To change the Hold Delay Time settings:

From the Setup Operation Menu, choose Hold Delay, as shown at right, and press Enter .

To change the time delay in minutes and seconds (in the range of 00:00 to 99:59):

• For minutes (MIN), press and hold one of the arrow keys ↑↓ to scroll through the numbers 00-99.

• Press Enter to advance to seconds (SEC).

• For seconds (SEC), press and hold one of the arrow keys ↑↓ to scroll through the numbers 00-59.

• When finished, press Enter again.

7.10.5Specify Restart Time

The restart delay timer directs the AC8 to wait a specified time before changing the state of an out- put. This feature can prevent needless responses to transient conditions.

If two or more outputs change state simultaneously, the AC8 begins a new countdown between each output change of state.

The default is 6 seconds (displayed as 00 MIN : 06 SEC). To change the Restart Time settings:

From the Setup Operation Menu, choose Restart, as shown at right, and press Enter .

To change the time delay in minutes and seconds (in the range of 00:00 to 99:59):

• For minutes (MIN), press and hold one of the arrow keys ↑↓ to scroll through the numbers 00-99.

• Press Enter to advance to seconds (SEC).

• For seconds (SEC), press and hold one of the arrow keys ↑↓ to scroll through the numbers 00-59.

• When finished, press Enter again.
