OS Loop Coordinator

Application

Modular smoke ventilation.

Description

Centralized coordination module for smoke and heat extract ventilation systems, for use with between 1 and 64 remotely-mounted manual control points (MCPs). Larger systems can be constructed by linking together multiple coordinators.


Features and benefits:

  • 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 circuitry, which also monitors actuator cabling and circuitry for faults. When a fault occurs, a signal travels to the coordinator and from there to the remote alarms.
  • The coordinator contains the mains power conversion electronics, which provides the 24 V d.c. power for operation.
  • Contains a back-up battery supply.
  • pr BS EN 12101-9 and fully EN 12101-10-compliant.
  • Single mains power connection.
