Room Integrety, Fire suppression and Air sampling VESDA specialists. 

Inert gas suppliers and testing specialiasts

We also offer a range of additional Fire and Security solutions.

Integrity testing is one of the most important components of any fire suppression system.

Imagine having installed a fire suppression system and it does not function correctly because the room was not adequately sealed and the suppression agent leaked out before a fire could be extinguished. Or the room was sealed too tightly and the suppression release damaged the structure of the room!

At A P Solutions we include integrity testing with all the systems we design and install, by our fully traded level 3 engineers.


We can carry out Integrity testing on a wide range of suppression systems and can carry out annual integrity testing of a wide range of manufacturers systems. We can provide pressure relief dampers if required and can offer an installation service.


We offer a full room sealing service to a guarenteed pass!!

The effectiveness of a gaseous fire suppression system
can only by guaranteed by regular ongoing maintenance
of that facility.

As part of an annual program of system maintenance, integrity testing of the protected enclosure must be undertaken to ensure that, on discharge, the extinguishing agent achieves the correct concentration at the necessary height for the minimum required retention time.


ISO 15004 states that an enclosure protected by a gaseous extinguishing system must be integrity tested on an annual basis or when changes are made to the enclosure boundary such as new cable penetrations.

Remember before you consider installing any fire suppression system contact A P Solutions. We would be pleased to discuss and give any advice you may require.

Room Integrity Testing
What is "Room Integrity Testing" and why should it be done?
Effective Fire Suppression
The effectiveness of a gaseous fire suppression system can only be guaranteed if it is
regularly checked. If the system does not achieve the right concentration or does not hold
that concentration for long enough it may not work!
Risk Limitation
The fire suppression system is there to ensure any loss of business continuity and any
collateral loss is kept to a minimum. Insurers and business managers need to have the
comfort of knowing that the fire suppression system will work.
Discharge Testing
Full discharge tests are expensive and in the case of Halon 1301 (BTM) it is actually illegal.
If there is a leak a discharge test won't tell you where it is.
Standards and Recommendations
BS5306 requires all gas systems to have an integrity test annually. A competent specialist
should carry out the Integrity Test. The equipment should be designed specifically for this
purpose and be regularly calibrated. The Test should be carried out in accordance with
BS5306 or NFPA2001.
When should Integrity Tests Be Done?
An integrity test should be done immediately after a system has been installed and routinely
every year thereafter. Any alteration such as changing a door or putting a new cable
through a wall can affect the room's gas holding ability. Routine servicing will not reveal
this. So an Integrity Test should be carried out after any alteration and the annual testing
dates adjusted to follow annually thereafter.
