The diagram below shows Maintained Live generated from the
internal link of the mains supplied to the unit. Alternatively, the
external shorting link can be removed and an external supply (from
the same phase) can be connected to create a Maintained Output.

Connecting Presence Detectors
The following SELV detectors are designed to interface to the D
CDH8U5:
• D MLS2500CDRR4 Corner-mount Microwave presence detector
with photocell, semi-flush mounted. Available with surface
mount (SM suffix).
• D MLS2001CDR 360° PIR presence detector with photocell,
flush mounted. Available in surface mount version (SM suffix).
• D MLSM2002CDR Controller for a 360° PIR detector with
photocell. Used with the D DHS or D DHW mini-head to form an
integral luminaire-mounted unit.
Each connects to the D CDH8U5 by means of an Ethernet-style
RJ45 connector terminated patch lead which are available ready-
made in 2m, 3m, 5m and 10m lengths. Up to five detectors may be
connected to a D CDH8U5.
