C: WIRING SPECIFICATIONS
The following specifications must be observed when
installing Euro-MERiDIAN alarm systems:
A: General Principles:
1 Routing: NO alarm system cable should be run with other cables
carrying AC or digital signals
2 Insulation: Protected by the use of grommets, etc. where appropriate.
3 Specifications: The following specifications for cable types and distances are
important for reliable operation.
B: RS-485 Wiring (Keypad, etc. connections):
1Cores 4
-
core minimum. Use of 6
-
core and doubling up supply cores
is beneficial to minimise volt drop, but NEVER double
communications connections (D3
-
4)
2 Cable type: Twisted pair, eg Belden 9744 (unscreened) or 9502 (screened).
3 Wiring format: Parallel,
daisy
-
chained.
4 Cable length: Overall network max 1 Km.
5 Termination:
Extreme end points fitted with 120
!
resistors between D3 / D4
C: End of Line Zone Wiring
1Cores 4

core
2 Cable type: Standard alarm cable; screened if required by environment.
3 Wiring format: Detectors wired using EoL resistors, mounted at detector.
4 Cable length: Max 1 Km per detector.
D: iD Wiring
1 Cable type: Screened. 4
-
core minimum.
Doubling up supply cores will minimise
volt drop to detectors. Doubling of iD cores is also possible
2 Wiring format: Any parallel format, except
ring main
loops.
3
Termination
0.01µF
capacitor between iD+/- at end of each cable run.
4 Cable length: Max 100 metres for any cable run.
5
Biscuit location:
Must be wired directly to detector terminals.
If it is impossible to locate the biscuit in this way, a
DP
junction box must be used.
6 Checks: All commissioning checks must be performed and recorded.
7 Warning: In some situations, especially take
-
over sites using existing
wiring, iD technology may not be suitable.
Castle Care-Tech Ltd. cannot be held responsible for
problems arising from failure to follow this specification
