Finding Detectors That May Need Servicing - Kidde VM-1 User Manual

Finding detectors that may need servicing

The VM-1 control panel provides the following maintenance reports to help you
find out if any addressable smoke detectors need servicing. Any of the reports
can be displayed on the LCD screen or printed on a local printer.
The reports show the %Dirty values of the devices. This value is an indication of
a smoke detector's ability to compensate for dust and dirt buildup inside the
chamber. Smoke detectors with higher %Dirty values are less able to
compensate. The available reports are:
• Dirty Devices > 80%: Lists all addressable smoke detectors that have a
%Dirty value of greater than 80%. Smoke detectors that are more than 80%
dirty should be cleaned or replaced as soon as possible. To view this report
you must know the panel address.
• Dirty Devices > 20%: Lists all addressable smoke detectors that have a
%Dirty value greater than 20%. A smoke detector that is more than 20% dirty
should be noted for possible cleaning or replacing. To view this report you
must know the panel address.
• Single Device: Lists the %Dirty value for a single smoke detector. 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 know the panel, card, and device address of the smoke
detector.
• Devices on a Card: 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. To view this report you must know the panel number,
card number, and loop number of the signaling line circuit.
To find detectors that may need servicing:
