SPH.27 Dali Hardwired Hub

Product Description

This unit enhances the SPECS3 lighting control system to provide DALI control to hardwired installations such as stairwells, toilets, lobbies and corridors. This unit is only suitable for control of luminaires fitted with DALI ballasts and DALI inverters, as all control is achieved digitally. This unit does not switch the power circuits, this means that lighting circuits are wired directly from the dist. board circuit breaker to the luminaires.

This unit provides two DALI drivers; this reduces DALI delays and reduces the chance of losing all control should a bus fault occur. Each driver is capable of controlling half the total loading of 40 ballasts or transformers and 20 emergency inverters (see note). E-Bus drivers are also provided that can accommodate 2x12 devices like presence detectors and switches. Up to 2x12 SPECS3 Dual-Bus sensors can instead be connected to the DALI bus to facilitate luminaire wiring. The unit is controlled using a message format that includes error detection, using single unscreened twisted pair cable called SPECS M-Bus.
