Simmtronic, a specialist
manufacturer of fully addressable digital lighting controls for corporate developments,
has developed a new hardwired hub for its proprietary SPEC3 systems driving
DALI technology.
Ideal for riser mounting, the new SPH.23 DALI Hardwired Hub enhances the SPECS3
lighting control system to provide DALI control to hardwired installations such
as stairwells, cloakrooms, lobbies and corridors. Designed for use specifically
with DALI ballasts and, in the case of emergency luminaires, a DALI inverter
all control is achieved digitally. As there is no switching of power circuits,
the hardwired lighting circuits can be wired directly from the distribution
board circuit breaker.
This advanced hardwired hub unit provides two DALI drivers to reduce delays
and minimise the chance of losing all control should a bus fault occur. Each
driver can control half the loading of 40 DALI ballasts or transformers and
20 emergency inverters. It incorporates built-in E-Bus drivers that can accommodate
24 function devices, e.g. presence detectors and switches. The unit is controlled
using an advanced message format that includes error detection and self-correction,
using SPECS3 M-Bus single unscreened twisted pair cable,
Simmtronic has successfully completed more than 600 commercial projects, supplying
future-proof, fully addressable lighting control systems for many of the UK’s
largest and most prestigious corporate developments and has already supplied
many of the largest DALI projects to date.
