Connecting Presence Detectors

The following SELV detectors are designed to interface to the CDH4U5:

MLS2500CDR

Corner-mount Microwave presence detector with photocell, semi-flush mounted. Available with surface mount (SM suffix).

MLS2401CDR

360° Microwave presence detector with photocell, flush mounted. Available in surface mount version (SM suffix).

MLS2001CDR

360° PIR presence detector with photocell, flush mounted. Available in surface mount version (SM suffix).

MLSM2002CDR Controller for a 360° PIR detector with photocell. Used with the DHS OR DHW mini-head to form an integral luminaire-mounted unit.

Each connects to the CDH4U5 by means of an Ethernet-style RJ45 connector terminated patch lead which are available ready-made in 3m, 5m and 10m

lengths. Up to five detectors may be connected to a CDH4U5.

Positioning Presence Detectors

For information on installing and positioning detectors, please refer to the installation instructions provided with the particular detector.

Connecting Switches

The CDH4U5 is equipped with SELV switch inputs which will typically be two way, centre off, momentary rockers, (e.g. the MK K4900 range). The logical

function of a switch can be configured from a wide range of options and its action can be associated with any combination of channels. The switch connection

consists of a 3-pole pluggable terminal block comprising a common and two returns from normally open contacts. Four plugs are provided with each CDH4U5,

additional plugs can be ordered using the code CDHIP (5 pieces per pack).

The recommended cable for use with the SELV switches is 3-core 300/500v 0.75mm≤ cable to CMA Reference 3183Y or for LS0H, to CMA Reference 3183B.

The maximum allowable cable length between the switch mechanism and the CDH4U5 terminal block is 100m.

Three separate single wires should not be used.

Connecting the Communications Bus (MLS)

It is imperative that the MLS Bus be wired in the correct type of cable. Normally it should be 1.5mm unscreened twisted pair. See Application Note AN4001.

Do not connect Mains to the MLS Bus.

DIMMING CHANNELS

For connection of Bus Power Supply variants, see also Supplementary Installation Instructions W5071.

Note that if the SELV status of any one of the switches

is compromised by reason of inadequate insulation or

segregation of the cabling, then the SELV status of all

other switches AND OF THE DETECTORS will also be

compromised.
