SECTION 2 - ALARM CONDITIONS
When an alarm condition is detected by the 4120 FIP, it is indicated by the following:
• Red "ALARM" LED is flashing.
• Tone-alert is pulsing.
• LEDs on the local annunciator may illuminate.
• Alphanumeric display will show an alarm condition.
ALARMS = 1
The display has one red LED which is used to indicate an alarm condition. When an alarm
occurs, the red LED flashes, the tone-alert pulses, and an alarm message is displayed on
the alphanumeric display. The red LED will glow steady and the tone-alert is silenced upon
activation of the <ALARM ACK> key. When the alarm condition clears, the red LED will turn
off and the alarm will be removed from the alarm list. Once alarm conditions have been
cleared, Alarm events can be reviewed by examining the historical alarm log.
