SUPERVISORY SERVICE CONDITIONS
INTRODUCTION
A Supervisory Service Condition is used to indicate the operative condition of Automatic Sprinkler Systems and
other systems used for the protection of Life and Property. A Supervisory Service indication may indicate that one
of these systems is inoperative.
NOTE:
Refer to Figure 4 for locations of Operator Interface Panel LEDs and Keys.
When a System Supervisory Service Condition is detected by the NDU, the condition is indicated by the following:
l

l
Tone-alert is on steady

The panel has one yellow SUPERVISORY SERVICE LED which lights when a supervisory service condition is

supervisory service message is displayed by the alphanumeric display on the interface panel. When the &UPV
ACKz key is pressed, the SUPERVISORY SERVICE LED flash becomes a steady glow, and the tone-alert is
