1Network module (SAFEDLINK) FN2001

1.1 Description

The network module FN2001 (SAFEDLINK) is used to network several via the system

bus FCnet/C-WEB. FN2001 may only be used for networking in a fire detection

system.

The network module is plugged onto the PMI & mainboard and has the following

features:

lConnections for a system bus input and a system bus output

lIntegrated degraded mode function with signal transfer in the event of line trouble

lElectrical isolation between the system bus and the panel

lGround fault supervision

lSignal transfer in the event of line trouble caused by redundant networking with

one network module per panel

1.2 Installation

The network module (SAFEDLINK) FN2001 must be installed in the left slot (X13)

(main module slot).

X13

Installing the network module (SAFEDLINK) FN2001

1Fastening tabs on operating unit

2Nut for screwed cable gland (2 per module) 1

3Cable gland (2 per module) 1

42x fixing screw

5Network module (SAFEDLINK) on X13 (master module)

X3 FCnet/SAFEDLINK or C-WEB/SAFEDLINK connection terminal

X13 Connection terminal on PMI & mainboard

1When using shielded cables, the cable glands are needed to secure the shielding.

Make sure you install the network module (

SAFEDLINK

) in the correct position (plug

X13) during installation.

1. When shielded cables are used, mount the two cable glands (3) with the nuts (2)

on the flange between the fastening tabs (1).

2. Plug the network module (SAFEDLINK) (5) into the connector X13 as shown.

3. Fasten the network module to the fastening tabs (1) using the two fixing screws (4).

4. Check that the network module is secured correctly in order to prevent open

circuits.

5. Wire up the system bus SAFEDLINK according to the pin assignment.

1.3 Installing the shielding

If using shielded cables, the cable gland must be fitted.

Installing the shielding

1 Nut

2 Sealing element

3Contact sleeve

4Bottom part of cable gland

5Braid

XLength of contact sleeve

1. Pull nut (1), sealing element (2) and contact sleeve (3) over cable.

2. Trim outer cable surround to the desired length.

3. Trim braid or shield film to the contact sleeve (X) length.

4. Slide nut (1), sealing element (2) and contact sleeve (3) to end of surround.

5. Place braid or shield film over contact sleeve (3). Cut off protruding material.

6. Guide the prepared cable into fitted bottom part of cable gland (4) until sealing

element (2) and contact sleeve (3) are flush in bottom part.

7. Screw nut (1) to bottom part such that the cable is firmly pressed in.
