OSLoop coordinator:

A modular smoke control system linking 1–64 remotely mounted manual control points (MCP's) via a coordinator. The coordinator contains the mains power conversion electronics which provides the 24 V DC power for operation. It also contains a back up battery supply. Each MCP contains actuator circuitry which also monitors actuator cabling and circuitry for faults. When a fault occurs, a signal is sent to the coordinator and from there to the remote alarms.

OS2 Control panel:

Suitable for standalone systems through to fully networked intelligent SHEV systems with BMS interface. Operates on a mains voltage primary power supply and contains integral fully monitored and intelligent battery backup for secondary power operation.
