There are two types of acknowledges for the 4100 system: Global Acknowledge and Individual Acknowledge. Each
acknowledge type operates with the Supervisory Service Condition in the following manner:
• Global Acknowledge – When Global Acknowledge is used on the 4100 system, a single key press of the
<SUPV ACK> key acknowledges all supervisory service changes in the system. If status change information
is required, you may review this data (after a 30-second delay) by pressing the <SUPV ACK> key and reading
the total number of supervisory service changes on the alphanumeric display.
• Individual Acknowledge (For NFPA 72 Proprietary Receiver Requirements) – If a supervisory service
condition has been acknowledged with the <SUPV ACK> key and further unacknowledged conditions remain
in the system, the tone-alert continues to sound and the next status change is shown on the alphanumeric
display. This process repeats until all changes are acknowledged. When this occurs, the tone-alert silences
and the highest priority acknowledge change appears on the display.
