Fortress Interlocks CPS4STOPXP safety switch key station

The Fortress Interlocks CPS4STOPXP is an ATEX-certified, explosion-protected safety switch key station. It is designed to release keys which can be used to control mechanical door locks that provide access to machinery and process lines operating in potentially explosive environments.

Both the switch and the door locks are suitable for use in zone 1 and 2 environments such as those found in the chemical and petrochemical, paint, pharmaceutical, flour, powders and mining industries; the electrical parts being IP67 rated.

The heavy-duty safety switch key station is available with up to a maximum of five safety key adapters. By turning the first key, the machine is isolated and the other four keys are released. These keys can be used to open a maximum of five ATEX certified ‘DM’ mechanical door locks that give access to the safeguarded area. Restarting the machine is only possible when all keys are back in the key control station.

The interlocking system complies with the ATEX Directive and meets EExd IIC T6 category II2 GD and SIRA 00ATEX 1037X. Sealed to IP67 and IEC 60529, it is protected against corrosion, water, dust and oil.

It features dual-channel safety circuits with positive-break switches and is manufactured from stainless steel and zinc alloys for smooth operation.
