Alarm Operation - Honeywell NOTIFIER SFP-10UD Series Manual

Operating Instructions
Pressing the Acknowledge/Step or Alarm Silence key will cause the pulsing piezo to silence and the
system Trouble LED to change from flashing to on steady. This block acknowledgment occurs
regardless of the number of troubles, alarms and supervisory events active in the system. When the
Acknowledge/Step key is pressed and at least one new alarm or trouble exists in the system, the
'acknowledge' message is sent to the printer and history file. If the trouble clears, either before or
after the Acknowledge/Step key is pressed, the 'clear trouble' message is sent to the printer and his-
tory file.
If all troubles clear and there are no supervisory or fire conditions active in the system, the system
returns to normal mode operation and the System All Normal message is shown on the LCD display
and sent to the history and printer files. The auto-restore feature will restore cleared troubles even
if the troubles were never acknowledged. Note that pressing the Alarm Silence key when only trou-
bles exist in the system will have the same effect as pressing the Acknowledge/Step key except the
Alarm Silenced LED will light.

4.5 Alarm Operation

Alarm operation is similar to trouble operation with the following differences:
• The piezo sounder produces a steady output as opposed to a pulsed output
• The Fire Alarm LED flashes 1 second On and 1 second Off
• The LCD displays Alarm along with the device name, type, adjective/noun, associated zones
and time/date
• Communicate the alarm to the Central Station
• Alarms latch and are not allowed to clear automatically
• Timers for Silence Inhibit, Autosilence and Trouble Reminder are started
• Alarms activate the alarm relay
• Silenced alarms are resounded
• The trouble relay is not activated
• Store event in history buffer
• Terminate upload or download communications
