Acknowledging Supervisory Conditions
What Acknowledge
Does
The first step in managing a supervisory condition is to acknowledge the condition.
Acknowledging a supervisory does two important things:
• It records the time and date at which you observed the presence of the condition, and stores
that information in the system's historical log.
• When you press the acknowledge key, the system displays specific data on the location of the
supervisory condition.
It is important to understand that the FACP can be configured with either global or individual
acknowledge. These options function as follows:
• Global Acknowledge. When global acknowledge is enabled, one press of the SUPV ACK
key acknowledges every point currently reporting a supervisory condition.
• Individual Acknowledge. If individual acknowledge is enabled, the SUPV ACK key must
be pressed to individually acknowledge each supervisory condition. Individual acknowledge
must be selected if the panel is providing proprietary receiving service in accordance with
NFPA 72.
The SUPV ACK key, which is used to acknowledge supervisory conditions (either globally or
individually), is located just beneath the "SUPERVISORY" LED.
Globally
Acknowledging
Supervisory
Conditions
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 display shows the supervisory condition, similar to
Figure 4-1.
2. Press the SUPV ACK key under the flashing yellow LED. The display shows a list of all the
devices reporting a supervisory condition. The tone-alert silences, and the yellow LED glows
steady.
Read the display. Investigate the problem to determine its cause. Make the necessary repairs in
accordance with the manufacturer's instructions, or call an authorized Simplex representative to
repair the system. If the panel has not been programmed for latching supervisory operation, when
the problem causing the supervisory is corrected, the supervisory automatically clears and, after a
delay, the display indicates that the system status is normal. With latching supervisory operation,
the system requires a reset after the problem has been corrected, in order for the supervisory
condition to clear. Refer to 579-849 ES Panel Programmer’s Manual for instructions on program-
ming latching supervisory operation
