19 Supvr Button / LED Pressing the Supervisory button places the contents of the
Supervisory queue onto the display screen for review. Active
supervisory events are displayed in the order in which they are
received. When a supervisory event is highlighted on the display,
pressing the Supervisory button acknowledges the event and
advances the display to the next event.
The Supervisory LED serves as a common supervisory event
indicator. The LED, when flashing, indicates that there is an
event in the queue that has not been reviewed (local systems) or
acknowledged (proprietary systems). When on steady, the LED
indicates that all events in the queue have been reviewed or
acknowledged.
Note: Security events allow for multiple activations from the
same point. It is not uncommon for this to happen.

The Alarm silence LED, when lit, indicates that the active
notification appliance circuits have been silenced.
