flex7 Applications 2 x PELV Occupancy Control + Global Emergency Test

flex7 applications 2x PELV Occupancy Control + Global Emergency Test

An Office and adjoining Store Cupboard, each protected by different devices at the distribution board (could be different phases), requiring individual occupancy control, but a single key switch to facilitate emergency test across both circuits.

Each space has its own flex7 starter Distribution Box with a separate 3-core supply (LNE) back to the distribution board; no separate emergency live is required.

Control of the Office and the Store Cupboard luminaires is via separate flex7 plug-in sensor heads operating at PELV. The luminaires are automatically switched on when movement is sensed. After the room is vacated the luminaires in that room switch off when the timeout period has elapsed.

The plug-in switch drop is connected to a latching key switch located next to the office door and operates at PELV. The switch affects the separate emergency relay in both networked control modules, simultaneously initiating the emergency test across both separate circuits.

Note: emergency control modules can be configured so that during a test all connected luminaires are isolated from the supply or only emergency luminaires are isolated leaving non-emergencies fully operational.
