Our customized maintenance program reduces the risk of incident and failure, makes sure the system’s performance is always at its best, extends the system’s life span and reduces the false alarms when available, thus contributing to a significant reduction in maintenance costs throughout the duration of operation.
What a DHAS maintenance contract covers
Every system DHAS installs comes with a one-year warranty. After that, a maintenance contract keeps it in peak condition:
- Scheduled preventive visits, planned per system, to test, clean and adjust before something fails.
- Assistance 24 hours a day, 7 days a week, with technicians and engineers ready to respond.
- Corrective visits on request when something goes wrong between scheduled visits.
- Performance maintenance: fine tuning, and upgrades when the system needs them.
- A record of every visit, under our ISO 9001 quality system, certified since 2005.
The result: fewer failures and false alarms, a longer life for the system, and lower costs over its lifetime.
What we check on a preventive visit
- Fire alarm: detectors, call points, sounders, panel batteries and the event log, and the links to doors, lifts and ventilation.
- Gas suppression: cylinder pressure and agent, release circuits, abort and manual release buttons, sealing of the room.
- Automatic doors and gates: sensors and safety beams, motors and drives, locks, manual release and emergency opening.
- Barriers and parking: arms, safety loops and photocells, ticket dispensers, readers, pay stations and plate cameras.
- CCTV and access control: camera image and focus, recording, readers, locks and door contacts.
- Intrusion alarms: every detector, the sirens, tamper switches and backup batteries.
- Lightning and surge protection: earthing resistance measured, surge protectors checked and replaced when worn.
The exact checklist for your systems is agreed in the contract.
Monitoring between visits
A building can also watch itself between our visits. At our own headquarters, Home Assistant reads the KNX installation, the solar inverter, the generator, the fire panel and the UPS units, and more than 30 alert rules warn before problems: a weak generator starter battery, a failed generator start, a hot server room, a UPS running on battery, a low water tank. Generator service hours and the dust on the solar panels are tracked, so maintenance is planned, not reactive.
We can set up the same monitoring in your building, with alerts sent to your team’s phones. Read the full headquarters case study.

Frequently asked questions
What happens when the warranty ends?
Every installation comes with a one-year warranty. At its end, we propose a maintenance contract so the system stays in peak condition.
How often do you visit?
The schedule is set for each system and agreed in the contract, based on the type of system and how heavily it is used.
Can we call you outside working hours?
Yes. Clients under contract get assistance 24 hours a day, 7 days a week.
Why maintain a system that works?
Detectors get dirty, batteries age, and motors and sensors wear. Preventive visits find these problems before they cause a failure or a false alarm, at a lower cost than emergency repairs.
