4. INSTALLATION GUIDANCE

An intruder alarm system can be

broken down into four major

parts:

1. Control Panel and Keypads

2. Detectors

3. Sounders and other

outputs

4. Communications

We recommend that the

installation is carried out in these

four steps, and that each stage is

tested before proceeding to the

next.

This manual provides the

necessary information to install

the system and carry out the

principal

programming

functions

For most installations, we

recommend that you

change only the options

highlighted in this basic

manual.

The full Engineer’s Manual

explains these options in

additional detail, as well as

providing details of the

additional facilities available

when the ‘MSX Card’ is fitted.

NOTES:

1. Connections should NOT be

made to equipment whilst it is

powered up!

2. Please ensure that the power

supply of the Control

equipment is adequate for the

system it is intended to power

from it. If appropriate, select a

unit with a larger power

supply, or include additional

power supplies in the system

specification.

WIRING SPECIFICATION

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: Protect 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):

1 Cores 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

9502 (screened)

or Belden 9744 (unscreened)

3 Wiring format: Parallel,

‘

daisy

chained.

’

4 Cable length: Overall network max 1 Km.

5 Termination: Extreme end points fitted with 470

Ω

resistors between D3 / D4 if

exceeds 20m.

C: End of Line Zone Wiring

1 Cores 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 PLUS 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. Spare cores should be earthed to prevent AC noise.

2 Wiring format: Any parallel format, except

‘

ring main

’

loops.

3 Termination

0.01

F 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

‘

’

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
