Screened Cable

Screened cable may prove necessary if the installation
site has equipment that produces high levels of R.F.
(Radio Frequencies), e.g. heavy industrial plant like
welding equipment etc. If screen cable is required you
should adhere to the following guidelines:
1. The screen on the cable should only be connected
to mains earth at the control panel.
2. The continuity of the cable screen is most important
and screening MUST be continuous along the full
length of the network.
3. If the network cable enters any metal enclosures,
make sure the screen remains isolated from the
case.

Electromagnetic Compatibility

When used as intended this product complies with EMC
Directive (89 /336 /EEC) by meeting the limits set by the
standards BS4737, EN50082-1 1992 and EN50130-4
1993. The following installation guidelines must be
followed.

1. External cables must be connected using cable
entries or knockouts provided.
2. When routing external cables inside the product
they must be:
(a) Kept as short as possible.
(b) Routed close to the housing.
(c) Kept as far as possible from the electronics.
3. Any modifications other than those stated in this
manual, or any other use of this product may cause
interference and it is the responsibility of the installer
to comply with the EMC and Low Voltage Directives.

XNode Wiring

The XNode requires a 4 core cable for interconnection,
and up to 16 may be connected in a "daisy-chain" or
"star" configuration. The distance between each
XNode must not exceed 100 metres. The total distance
to last XNode must not exceed 1000 metres. Power for
detectors is provided by the Aux. +/- terminals.
