A gas suppression system spends years doing nothing — then has one chance to do everything. Gemini AMPM services suppression systems to the BS EN 15004 maintenance regime: periodic inspection, cylinder weighing and pressure checks, agent integrity and the records your insurer expects. Every contract carries 24-hour named-engineer response.
Our maintenance follows the regime set out in BS EN 15004 and ISO 14520, tailored to the manufacturer’s requirements and your insurer’s expectations — typically two service visits a year. Engineers inspect the control equipment, actuation lines, detection interface, pipework, nozzles and cylinder installation, and check whether anything about the room itself has changed since the last visit. New cable trays and missing ceiling tiles sink more systems than component failure ever does.
Agent integrity is checked properly, not glanced at. Halocarbon cylinders — Novec 1230, FM-200 and their predecessors — are weighed or level-checked to confirm contents; inert gas cylinders are pressure-checked with temperature correction. Where losses exceed the thresholds the standard allows, we investigate the cause and arrange recharge or replacement before the shortfall becomes a failure to discharge.
Every visit produces a service report worth keeping: findings, agent records, test results and remedial recommendations, building an asset history your insurer and your fire risk assessor can rely on. Under the Fire Safety Order the duty to maintain sits with you; our documentation is how you prove it was met. When something needs fixing, you get a priced recommendation — not a vague note and a shrug.
We maintain systems of every make and vintage, whether we installed them or inherited them, and one consolidated contract can cover suppression alongside your wider fire and security systems. Behind every contract sits Gemini’s 24-hour named-engineer response: a person who knows your site and your system, not a ticket number in a queue. That is what standby readiness looks like.
BS EN 15004 and ISO 14520 set out a periodic inspection regime, and in practice most systems need two engineer visits a year, with specific checks at different intervals and manufacturer requirements layered on top. Insurers frequently mandate the schedule as a condition of cover. We build each contract around the standard, the manufacturer and your policy wording — then keep the records that prove every visit happened.
The standards set clear limits — broadly, a halocarbon cylinder needs attention if it loses more than five per cent of agent or ten per cent of pressure, and an inert cylinder if it loses more than five per cent of pressure. Beyond those thresholds we investigate the cause, arrange recharge or replacement and recommission the system. A slow leak found at service is a line item; found at discharge, it is a disaster.
Yes, and we do it often. We start with a full survey: agent quantities, cylinder condition, actuation, detection interface and the state of the enclosure. You get a baseline report on what you actually own — including anything the previous contractor left unsaid — then a maintenance contract built on it. We work across all major manufacturers and, as an approved Fike installer, hold direct access to Fike parts and support.
A named engineer, not a call centre, comes back within 24 hours. Tell us the building and what you’re dealing with, and we’ll scope it properly.
