Natural Smoke Ventilation

Our control systems are available in two different configurations, OS2 and OSLoop.

The OS2 SHEVTEC Controller is an intelligent 24V dc control system designed smoke control and/ or environmental ventilation system the OS2 SHEVTEC controller can deliver up to 8A to drive 24v motorised actuators and magnetic catches. Battery backup is provided for continued operation after a mains supply failure. Each controller is linked to the others to produce a networked control system. 

The networked control system can operate standalone or be linked to a house fire alarm or Building Management System delivered in accompaniment to a full range of AOV smoke dampers, roof vents.

OSLoop is a fire only system but can allow limited environmental by the addition of OS2 panels on the network. It Utilises a single panel and powered (24V) loops

The OSLoop coordinator controls power and data to the networked system fully monitoring primary (mains) and secondary (battery) power supplies. The OSLoop system intelligently monitors current requirements of the system and determines how and when the MCPs can call on this power to activate AOVs. Each MCP contains actuator switching circuitry which also monitors the actuator cabling and circuitry for faults.

If a fault is detected, then the MCP raises a local alarm and also informs the coordinator so the remote alarms can be triggered. The MCP also provides support for one or more smoke detectors. Again this circuitry monitors the detectors and cabling checking for faults. In addition the MCP can be configured as master/slave device to other MCPs in the same system.

In addition to both systems, our unique proposition is the incorporation of tested EN12101-2 window actuators across a substantial number of system company profiles which means our UK smoke ventilation contracting entity can directly deliver a comprehensive and fully compliant system offering without recourse to third parties.
