OS2 SHEVTEC Controller

The OS2 SHEVTEC Controller is an intelligent 24V dc control system designed to drive 2-wire 24V dc actuators in a Smoke Control and/or Environmental Ventilation System.

 

Product Details

Operating from a 230V ac 5A supply, 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. OS2 SHEVTEC Controller can be mounted locally to the devices to be operated or in a centralised location. Each SHEVTEC Controller can operate independently or can be linked to others to produce a networked control system. The networked control system in turn can operate standalone or be linked to a building management system.

 

As standard

OS2 Control Panel:

24 V dc motor operating control panel suitable for the simplest stand alone system through to a fully networked intelligent SHEV system with BMS interface. The controller operates on a mains voltage primary power supply and contains integral fully monitored and intelligent 72 hours battery back-up for secondary power operation. Operation and control is compatible with OS2 MCPs and other control products.

 

OS2 Modular Control System:

The OS2 modular control system is designed to be flexible, by providing a smoke ventilation control system that can be interconnected to form a large centralized networked system on a module by module basis. The panel can receive 0–10 V inputs from a BMS system and in the event of a power failure, battery back up is provided for each module to ensure operation of the particular zone.

 

OS2 PSU 30/ 60 A Control Panel:

Control panel with a 24 V dc 30/ 60 A switch mode power supply via 4/ 8 separate fused outputs. An OS2 power and control board can be added for additional functionality. Suitable for larger single zone systems. The power supply unit is battery backed in mains power failure.

 

OSLoop:

OSLoop is a modular smoke control product. At its simplest, it consists of a centralised coordination module (the coordinator) and between 1 and 64 remotely mounted manual control points (MCPs). Larger systems can be constructed by linking together multiple coordinators. The coordinator module contains the mains power conversion electronics which provides the 24V DC power for the operation of the unit. It also contains a back-up battery supply to support this supply if the mains power input is lost. To keep the size of the power supply and batteries to a minimum, the coordinator determines how and when the MCPs can call on this power to move their actuators.
