WHAT IT IS

How aspirating smoke detection works

Sampling, not waiting for smoke to arrive

Instead of detectors on the ceiling, an aspirating system draws air through a network of sampling pipes to a central detector unit that analyses it continuously. Sampling points can be placed where ordinary detectors are hard to reach, and the system can pick up smoke very early.

That makes it a common choice for high ceilings, large open spans, high-value or high-risk storage, and secure areas where access is limited.

SERVICING

What an ASD service visit covers

Pipework & Airflow

Airflow checks and pipework inspection, so smoke can actually reach the detector.

Sampling Points

Every sampling point inspected, with the sampling channels cleaned.

Detector & Filters

Detector servicing, with filter changes as part of the full annual service.

Batteries & Logging

Battery health checks and back-up battery load testing, with system parameters logged on every visit.

Servicing is every six months, with a full annual comprehensive service, in line with BS 5839-1. You get a written record after every visit.

FAQ

Common questions

Which aspirating smoke detection systems do you service?

We service Wagner Titanus and VESDA aspirating systems.

How often does an aspirating system need servicing?

Periodic inspection and testing every six months, with a full annual comprehensive service that includes filter changes and back-up battery load testing, in line with BS 5839-1.

What is checked on a service visit?

Pipework and airflow, sampling points, the detector and its filters, and battery health. System parameters are logged so changes can be seen from one visit to the next.

Do you install new aspirating systems?

Yes. We install detection units and pipework, with containment managed on cable tray. Installations are quoted after a free site survey; see our installation page.

Can you service a system someone else installed?

Yes. Tell us the make and where it is, and we will confirm what is needed when we look at the system.

Does ASD replace the normal fire alarm?

In most buildings it is connected to the main fire alarm panel and works alongside it, so it is serviced and recorded as part of the same system.
