Fire and fault signals process to the control panel through standard loop wiring (conventional, addressable, or wireless) operated by an interface linked to the beam detector. The transmitter-receiver triggers the input signals on the interface when smoke is detected across the large space it is protecting. Beam detectors work better in larger, open space buildings than traditional smoke detection systems as they can be installed where smoke gathers. Due to stratification, smoke fields form in an inverted cone, rarely reaching the ceiling. Beam detectors are designed for premises with temperature extremes, excessive dirt, high humidity, and corrosive gasses. However, they are not best suited to be installed in outdoor areas, glass atriums, and areas where ice or condensation occurs, as this creates a challenge for the system.
