Systems Service

We carry out maintenance and visual checks on Fire Suppression and Detection Systems nationwide to ensure that they are operating correctly. All Fire Suppression and Detection Systems require regular maintenance to be carried out to ensure that they are operating correctly. Each manufacturer usually has their own recommendations as well as having local and international standards to cover the minimum requirements.

As a general rule, all fire suppression and detection systems require a minimum of two visits per annum. Note that this is a minimum not maximum and is dependent upon the environment, type of risk and individual customer requirements. More frequent visits may be required. During the visit some of the checks we carry are Agent Level, Pipework Integrity, Automatic Detection (including cleaning or replacement where required), Sounders, Control Panel and associated Equipment.

We also carry out a visual check of the protected area to ensure nothing has changed since the original design or last visit.

For Total Flood Systems (room protection) a Room Integrity Test should be carried out annually unless no new penetrations or holes have been made in the room since the last Room Integrity Test.

Repairs & Refills

At Chalis Fire Engineering Ltd even though we select reliable and high-quality products, things can still go wrong. Systems may require refilling due to a false discharge caused by user error or a fault.

On these occasions it is imperative that the system is refilled as quickly as possible. Most of our manufacturers offer urgent refills following a discharge and some even offer service exchange for inert gas. Full cylinders are delivered to site and the empty ones are picked up, this ensures a quicker turnaround than having to refill the cylinders that have discharged.


Systems that are no longer in use should be disabled, removed from site and disposed of or recycled. FM200 systems come under the F Gas Regulations and therefore require special attention and should be recycled.

Chalis Fire Engineering Ltd can remove any system for recycling/disposal including Halon. Please contact us for a quotation.
