The 2020P is a conventional (non-addressable) photoelectric smoke detector from the System Sensor Vision range. It uses an optical chamber combined with an ASIC to detect fires quickly and accurately, and the chamber design extends the time between cleaning.
An integral LED latches on to give a local alarm signal until the detector is reset by a short power interruption, and an optional remote LED can repeat the alarm. The detector fits the Vision range of bases.
