1 PURPOSE
The DOT ‐ 4046 multi ‐ sensor addressable smoke and heat detector is designed for detection of a fire
initial phase when a smoke occurs and/or
temperature rise may be observed.
The detector is
characterised by a high resistance level against wind movement and pressure change.
The DOT ‐ 4046 multi ‐ sensor addressable detectors are intended to operate in the POLON 4000 fire
detecting and alarm system control panel addressable lines. They are equipped with internal short
circuit isolators.
