It may be necessary during maintenance of the system to turn the outputs (for example
notification devices and relays) off.
Turning an output point off is effectively isolating that output. Once turned off, the output will
not turn on, even if an alarm condition that is programmed to turn it on, occurs. After the
maintenance it is necessary to return the output to automatic control.
Turning an output point on forces the output to activate, even if there is no condition present that
is programmed to turn it on. Some control points (e.g. Sonalert (buzzer) Inhibit, see below) are
normally off, and may be turned on to perform a function. These must later be restored to “off”,
not “auto“.
1. Select the output point that you want to turn off. Refer to Chapter 5 for information on
selecting
points.
2. Press the OFF key.
3. Press the <ENTER> key to confirm the operation.
Turning an output point on or off generates a “Manual Override Fault,” which is used to remind
you that the point has been manually turned on or off. You have to acknowledge the fault by
pressing the <FAULT ACK> key.
1. Select the output point that you want to force ON. Refer to Chapter 5 for information on
selecting
points.
2. Press the ON key.
3. Press the <ENTER> key to confirm the operation.
Turning an output point on or off generates a “Manual Override Fault,” which is used to remind
you that the point has been manually turned on or off. You have to acknowledge the fault by
pressing the <FAULT ACK> key.
When you are ready to return the point to automatic operation (i.e., the system, not the operator,
controls the point), you need to select the point, e.g. by repeatedly pressing <FAULT ACK>
until the point is displayed, then press the <AUTO> key and the <ENTER> key.
A loud buzzer is used in the Australian 4100U-S1 to meet the requirements of AS4428 (70dB at
1m with the door closed).
If doing testing or maintenance on the system with an operator at the panel, the buzzer may be
inhibited by turning point P198 on.
Note that the point must be turned off when the panel is to have its door closed.
