Pressing the SUPV ACK key once globally acknowledges all supervisory conditions that exist
within the fire alarm system. In addition, the “SUPERVISORY“ LED changes from flashing to
steady ON and the tone-alert silences.
If global acknowledge is enabled on your system, use the following procedure to acknowledge the
supervisory conditions.
1. Unlock and open the enclosure door. The alphanumeric display shows the supervisory
condition, similar to the following example.
2. Press the SUPV ACK key under the flashing yellow LED. The alphanumeric display shows
the area and type of condition. The tone-alert silences and the yellow LED glows steady.
Read the alphanumeric display. Investigate the problem to determine its cause. Restore or replace
the defective device (switch, wire, notification appliance) in accordance with the manufacturer’s
instructions, or call Simplex to repair the system. When the problem causing the supervisory is
corrected, the supervisory automatically clears and, after a delay, the alphanumeric display
indicates that the system status is normal.
If individual acknowledge is enabled on your system, you need to separately acknowledge each
supervisory condition. Use the following procedure to do this.
1. Unlock and open the enclosure door. The alphanumeric display shows the supervisory
