Finding detectors needing maintenance
The EST4 control unit provides maintenance reports to help you find out if any addressable smoke detectors need
servicing. The %Dirty value shown in the report is an indication of a smoke detector’s ability to compensate for
environmental conditions. Smoke detectors with higher percentages are less able to compensate.
The following maintenance reports can be accessed from the control unit'
• Maintenance (all): Lists the %Dirty value for all of the smoke detectors on a signaling line circuit. The report
also includes each smoke detector’s model type, primary and alternate alarm sensitivity values, and, if
programmed, a location description.
• Maintenance (device): Lists the %Dirty value for a single smoke detector. For CO detectors the report
includes CO Life Left Months or CO DAY Running. The report also includes the smoke detector’s model type,
primary and alternate alarm sensitivity values, and, if programmed, a location description. To view this report
you must select the device from the Project Tree.
• Maintenance Not Clean: Lists all addressable smoke detectors that have a %Dirty value of 80% and greater.
Smoke detectors that are more than 80% dirty should be cleaned or replaced as soon as possible.
• Maintenance Dirty: Lists all addressable smoke detectors that have a %Dirty value of 20% and greater. A
smoke detector that is more than 20% dirty should be noted for possible cleaning or replacing.
To find detectors that may need servicing:
1. On the Action bar, tap System Info.
2. On the Command bar, tap the desired maintenance report button. The report displays on the screen.
Tap the print button
⎙ to send the report to a local printer.
To view a maintenance report for a specific detector:
1. On the Action bar, tap Project Tree.
2. Expand the project tree by tapping the expand button , and then locate the target detector. For example,
FLR1W PCOS2.
3. Tap the detector. The Device Details screen appears.
4. On the Command bar, tap the Maintenance button.
Viewing history reports
The EST4 control unit provides history reports that list the most recent events or operator instructions processed
by the control unit for the previous month to current or since its history was cleared. The report includes the event
or system command name, address, time and date of occurrence, and the source that initiated the event or
command.
The history reports are listed below.
• History: All Dates report: Lists the last 20,000 events and operator commands processed by selected node
• History Alarm: All Dates, Alarm report: Lists the event name, time, date, and location text for all alarm events
• History Trouble: All Dates, Trouble report: Lists the event name, time, date, and location text for all trouble
events.
• History Supervisory: All Dates, Supervisory report: Lists the event name, time, date, and location text for all
supervisory events.
