SENSALINK SENLPS LT (96232304)
Only suitably qualified personnel should install this equipment.
Fixing
Connection
The SENSALINK SENLPS LT powers and synchronises the SensaLink Bus for up to 100 SensaLink
devices. Wall switch inputs allow simple dimming and on/off control over suitably programmed devices
in the system. There is no provision to link multiple SENSALINK SENLPS LT units together.
The SENSALINK SENLPS LT is supplied in a protective housing which should be mounted where it is
accessible for commissioning purposes.
It is imperative that the SensaLink bus is wired with the correct type of cable; normally it should be
1.5mm mains rated unscreened twisted pair. As the SensaLink Bus is polarity-conscious, care must
be taken to maintain polarity throughout.
Do not connect mains to the SensaLink bus as this will cause irreversible damage to all devices in the
system.
The mains supply, SensaLink bus and switch input terminals are suitable for 1 x 4mm or 2 x 2.5mm
cable.
Centre-off, three-way, momentary wall switches should be connected to the
‘
Wall Switch
’
UP and
DOWN terminals. Centre-off, three-way, latching wall switches should be connected to the ON and OFF
terminals. Each command actioned by the switch is addressed to all devices programmed to operate on
both Sensor Group 1 and Group 2 of the SensaLink System. All other sensor Groups remain unaffected
by the switch inputs.

Commissioning
The SENSALINK SENLPS LT has two modes of operation, depending on what range of equipment the
unit is being used in conjunction with.
Located at the bottom, left-hand corner of the unit is a four-way DIL switch. Switch number 4 determines
what bus type is being used. By default it is set to OFF.(All new SensaLink systems) ON = Old SensaLink
systems (Please contact Thorn Systems for advice)
Switch number 1, when set in the ON position, allows the SENSALINK SENLPS LT to operate in
‘
Commissioning
’
mode. In this state, any detector or device in the system which is programmed to any
group (via a SENSALINK SENLP (96102983)) can then be turned OFF by infrared override. This
override command will filter down to every device in the system enabling the operator to see that the bus
cabling is installed and functioning correctly.
Switches 2 and 3 have no function.
1. 4-way DIL switch. All switches set to OFF by
default. Switch 1 enables commissioning
mode; Switch 4 determines bus type.
Switches 2 and 3 - no function.
Input Indication LEDs
2. SensaLink Bus connections. Do NOT
connect mains to the SensaLink Bus.
Polarity must be maintained.
3. Switch input connections.
Important Additional Notes
1.
All terminals on this product are provided for final connections. It is not intended that the product be used as a junction box
for looping cables.
2.
A means for disconnection must be incorporated in the fixed wiring in accordance with the current wiring regulations.
