The Apollo 0893-01-01 is a Linear Beam Smoke Detector — designed to detect smoke in large areas, such as warehouses, gymnasiums, and high-ceilinged buildings.

It works by emitting a beam of light (usually infrared) from a transmitter to a receiver; when smoke particles pass through the beam, the intensity of the received light decreases, and the device triggers an alarm.

Main features:

Long-range coverage — monitors large areas with fewer installation points than point detectors.

Early fire detection in locations where smoke accumulates more slowly on the ceiling.

Flexible installation — can be mounted on walls or structures, covering up to hundreds of meters.

Compatible with Apollo addressable systems (in appropriate versions).

Ideal for industrial or logistics environments where ceiling access is difficult.
