The 4010 is a Global Acknowledge System which means ONE (1) press of an
<ACK> key globally acknowledges every abnormal point in the system in that
category. When acknowledged, an appropriate message is displayed.
When a point is acknowledged, the appropriate LED remains ON and the tone-
alert is silenced. The total number of alarm, trouble, and supervisory conditions
is shown in an alternating sequence on the display along with a prompt to the
press <ACK> for point review. Pressing <ACK> scrolls through the selected list
in chronological order. Each list is different and contains information
concerning a particular abnormal condition. In some cases, additional
information is available on the condition by pressing <ENTER>.
When an alarm condition exists, various signals, auxiliary relays, the city
connection, and the tone-alert may activate, depending on the system
configuration and the stage of the alarm condition. Turning signals, tone alerts,
etc. off is known as Alarm Silencing.
An important feature to be aware of when silencing alarms on the 4010 is its "re-
sound" capability. If, after silencing the signals, the 4010 detects another
abnormal condition, the zone with the abnormal condition is indicated on the
panel display, the appropriate indicator again flashes, and the signals sound
again.
Caution: Pressing the Alarm Silence key causes fire alarm evacuation
signals to turn OFF. Follow local procedures to silence alarm
evacuation signals.
To silence an alarm, press the <ALARM SILENCE> key. Two actions occur
when you do this:
•
The <ALARM SILENCE> key, when pressed, turns OFF all circuits
programmed to follow the Alarm Silence key.
•
The ALARM SILENCED LED turns ON and remains ON.
Note: If Waterflow/Sprinkler Devices are activated, notification
appliances may or may not be silenced (depending on local code
requirements). Usually, a dedicated bell continues to sound to
indicate waterflow.
