Thorn SENSALINK SENLPS G User manual

SENSALINK SENLPS G (96232305)
This latest generation SensaLink Bus Power Supply is for
use only with Thorn’s SensaLink Digital range of presence
detectors and accessories. Up to 99 SENSALINK
SENLPS G can be connected together (per installation)
increasing capacity to almost 20,000 devices on a single
SensaLink Digital system.
Installation & Connection
The SENSALINK SENLPS G Bus Power Supply should
be positioned in a readily accessible location, usually
adjacent to the mains distribution board for the area being
controlled. A fused 3A, 230 volt mains supply is required
which should be dedicated to the SENSALINK SENLPS G
for maximum reliability. This device MUST be earthed. It is
recommended that Double-pole Isolation is provided.
The SensaLink Digital bus network should be wired using
which
starts from the bus power supply and connects into every
SensaLink Digital device. Up to 200 devices can be
connected to one SENSALINK SENLPS G. Do not
connect mains to the SensaLink Bus.
This equipment should be installed only by suitably
qualified personnel.
1.5mm mains-rated, unscreened twisted pair,
Wiring Topology
The SensaLink Digital Bus may be wired in a ‘free
topology’ - i.e. any combination of spurs and rings. It is
recommended however, that a ring topology is used so
that the integrity can be checked. It should be wired from
the ‘OUT’ terminals to every device on the system, coming
back to the ‘RETURN’ terminals. The polarity of the
SensaLink Digital Bus must always be maintained. The
switch to the left of the bus terminal blocks, when pressed,
performs an integrity check on the bus. A correctly
installed system will cause the green LED below the
switch to flicker.

The spine should be linked to AB and YZ as shown (i).
Note that the screen is not shown, however, it must be
connected at each SLKGPSU.

Connecting Multiple SENSALINK SENLPS G
On larger installations where multiple SENSALINK
SENLPS G units are required, they may be connected
together via a ‘spine’ or ‘backbone’. The spine should be
wired using 24AWG twisted pair, screened
communications cable, e.g. Belden 9502. When
SENSALINK SENLPS G are linked in this way Common
Zone 1 becomes a ‘Building Zone’, providing building-
wide Common Zone 1 linking. The maximum length of the
spine should not exceed 1200m with all SENSALINK
SENLPS G being linked in a single spur.
Devices on the bus may be connected in any order.
Spurs are permissible but are best avoided as they will not
be checked during the integrity test.
Accurate as-fitted records will assist in fault finding.
The bus may be run with mains wiring providing twisted
pair bus cable as detailed above is used throughout.

least one unit must be set to address ‘00’ to act as
‘master’.

This command affects every device on the
SensaLink Bus.
Use a latching normally-open switch. When the switch is
made, all devices turn on at full brightness. The devices
will go to their ‘Entry Scene’ no later than 30 seconds after
the switch is released. Please note this function is also
available via a keyswitch on the front panel.
This command is addressed to each
device on the SensaLink Bus that has been programmed
to ‘Global Address 1 Rx: YES’.
Use a latching normally-open switch. When the switch is
made, all relevant devices turn off. The devices will begin
responding the movement again (go to their ‘Entry Scene’
if the area is occupied) no later than 30 seconds after the
switch is released.
This command is addressed to each
device on the SensaLink Bus that has been programmed
to ‘Global Address 2 Rx: YES’.
Use a latching normally-open switch. When the switch is
made, all relevant devices turn off. The devices will begin
responding the movement again (go to their ‘Entry Scene’
if the area is occupied) no later then 30 seconds after the
switch is released.
Front Panel
The status of each switch at any given time is indicated
through five green LEDs located on the front panel of the
SENSALINK SENLPS G. They illuminate only when the
switch associated with each command is closed. The
LEDs go out instantly when the switch is opened although
the actual command may still be active on the bus for up to
30 seconds.
The ‘All On Full’ command can be instigated via
keyswitch next to the LED array.
The red Power LED will illuminate when mains power is
applied to the unit.
The colourlessActivity LED flashes green only when there
is activity in any zone on the bus. It flashes red when a bus
installation fault is detected regardless of movement or
occupancy in the building. Please note that not all faults
will be indicated by this LED.
The yellow Linking LED will flash when multiple
SENSALINK SENLPS Gs are connected together and
Common Zone 1 linking occurs.
