Responding to off-normal conditions

EST2 System Operations Manual
During off-normal conditions, the 2-LCD sounds its internal
buzzer and displays a message to indicate a problem in the
system. You must press the Local Silence switch before you can
view messages other than the one displayed during the off-
normal condition. Once you press Local Silence, you may view
any message in any order by pressing the message review
switches.

Fire alarms

Smoke detectors, heat detectors, fire alarm stations, and
sprinkler systems may initiate fire alarms. The Alarm LED,
when on, indicates a fire alarm.
To respond to a fire alarm:
1. Press the Local Silence switch to silence the buzzer.
2. Read the display to determine the location of the fire alarm
condition.
3. Press the Alarm Review switch to view the alarm
message(s).
The Alarm Review switch will display any additional alarm
locations. Before you can reset the panel, the appropriate
personnel must:
• Put out the fire
• Investigate the cause of the fire
• Declare the building safe for re-entry
To reset the panel after a fire alarm:
1. Press the Alarm Silence switch to silence the audible
notification appliances.
2. Press the Local Silence switch to silence the buzzer.
3. Press the Reset switch to restore the panel to normal.
If either the Alarm Silence LED or Reset LED flashes, wait until
the inhibit period ends, then press the appropriate switch again.
The maximum inhibit period is three minutes.

Supervisory points

Active supervisory points indicate that a fire protection system
other than the fire alarm panel is off-normal. Conditions like
closed sprinkler valves and disabled supplementary fire
extinguishing systems may cause supervisory conditions. The
Supervisory LED, when lit, indicates a supervisory condition.
