INTRODUCTION
Photoelectric smoke detectors are easily contaminated by airborne dust and other particles. Even in "normal"
working environments, small amounts of dust inside a detector can affect detector sensitivity and cause false
alarms. In dusty environments, or during detector in: Jlation, large amounts of dust can enter and settle inside
a detector. Large amounts of dust almost always cause severe false alarm problems. For these reasons,
photoelectric smoke detectors must be inspected and cleaned at installation, and once every six to twelve months
thereafter (depending on the local environment). Local, state, or national codes may dictate otherwise.
This publication describes the procedures required to clean the Type 2098-9603 photoelectric smoke detector.
Once cleaned, the detector should be tested with smoke per local practice.
