EN54 information
Optional functions with requirements of this European standard
The Control panel complies with the requirements of EN54 : Part 2 : 1997. In addition to the basic requirements of the standard the
panel conforms to the following optional clauses:
Clause Description

7.11 Delays to action outputs
8.3 Fault signals from point
10 Test condition
System wiring
"
If instructed, the installer may need to terminate as well as connect the cables to the appropriate terminal blocks.
Cable separation
Where the outgoing and return cables of a loop circuit covers more than the equivalent of one zone they must not run together, for
example, either close to the Control Panel or in a service duct . There should be as much physical separation as possible between
the cables and the mechanical protection of the cable should be to a particularly high standard. This is to minimise the risk of
accidental damage to both cables.
Lightning protection
Where a loop cable is mounted to an external wall or between two buildings then consideration should be given to the use of
lightning protection devices.
