Need beam smoke detection? Start with a free site assessment.

Beam detectors monitor how smoke affects a projected light path across an open area. We assess the space, confirm the beam paths and mounting points, then handle installation, alignment and testing.

Is beam smoke detection right for your site?

Beam detection can cover large open areas where point detectors are difficult to place, but the beam needs a stable, unobstructed path and a suitable smoke layer.

How it operates

A transmitter and receiver, or a transmitter-receiver unit and reflector, monitor a light beam. Smoke obscuring the beam changes the received signal and can produce an alarm.

Where it fits

Often considered for warehouses, atriums, halls, hangars and other large open or high-ceiling areas where the approved design supports beam coverage.

What we check

Listed range, mounting stability, alignment, line-of-sight obstructions, ceiling geometry, stratification, airflow, sunlight or environmental effects, access and FDAS interfaces.

From
assessment
to
handover.

We review the property, required alarm sequence and existing interfaces before defining the FDAS scope and project sequence.

01

Site assessment

We review the property, current conditions, available plans and project requirements.

02

Design & planning

We define the panel, device layout, alarm sequence, interfaces and installation scope.

03

Review quotation

We discuss the proposed scope, inclusions, commercial terms and questions before approval.

04

Supply & installation

Equipment, cabling, devices and site work follow the agreed project scope.

05

Testing & commissioning

The installed system is tested and commissioned against the approved scope and sequence.

06

Service + BFP follow-up

We remain available for maintenance, project records and BFP-related follow-up within our scope.

Beam detection installed?
Keep the path clear.

We maintain existing beam detectors according to the installed equipment, alignment method, environment, access and agreed testing scope.

  1. 01

    Review detector status, mounting, reflector or receiver condition and visible beam path.

  2. 02

    Check alignment, contamination, obstruction and building-movement concerns.

  3. 03

    Perform the agreed sensitivity, fault, alarm and FDAS interface tests.

  4. 04

    Record results, corrective needs and BFP-related follow-up connected to our scope.

Beam detection,
made clear.

Straight answers about beam paths, large spaces, alignment, obstructions, maintenance and project information.

It uses a projected light beam between a transmitter and receiver, or between a combined unit and reflector. Smoke obscuring the beam changes the received signal and can trigger the programmed alarm response.
