Alarm reset button

When the alarm reset button is pressed the following events take place, even if the alarm
condition has not been corrected:
• The internal audible alarm buzzer stops buzzing.
• Any wired relay contacts return to their inactive state. If these relays are connected
to external alarm lights or alarm buzzers, those lights or buzzers shut off.
• If the original alarm condition still exists, the red main alarm light on the matrix's
front panel continues to flash. The red main alarm light only stops flashing when all
original sources triggering the alarm are corrected.
• If a new alarm condition or conditions occur before the original alarm conditions are
corrected, the internal buzzer and relay contacts will not reactivate. They will only
reactivate after all original alarm conditions are corrected.
