The BSR-6057 / A is an addressable visible smoke and thermal limit detector. Works with panels BSR-1116 and BSR2100. It sends a proportional value to the panel that depends on the amount of smoke in the room.

It consists of two parts. A plastic base mounted on the roof and the main body of the detector that fastens to the plastic base with a simple rotation to the right.

The detector has an indicator light that lights up continuously in case of fire detection, until a cancellation command is given by the panel. It also stays on when the sirens are stopped by the panel to indicate the detector from which the alarm was given. Turns off only after resetting the panel. The LED indicator also flashes every 8 sec as an indicator of good operation.
