4 Connecting an analogue dialer to the Edge RT7020

Enterprise

The Edge RT7020 simulates an analogue telephone line on the connector

block marked "LINE". Here two wires are connected to an analogue dialer's

line connector (ex Tx & Rx). The Edge RT7020 receives numbers dialed by

the dialer and delivers a start tone for SIA.

•

Handling of dialed alarms

As soon as the Edge RT7020 received the entire alarm correctly from the

dialer, the alarm is acknowledged to the dialer, and attempts are made to

deliver the message to the Connect platform. If the transmission to the

Connect platform despite the defined number of attempts, via Ethernet and

radio respectively, for some reason is unsuccessful. Then the Edge RT7020

will close the loop on the normally opened output REL4 for 2sec.

It is therefore recommended that output REL4 is connected to an input on

the panel so that a local alarm can be raised in the event of a transmission

fault.

5 Special considerations when connecting an Edge RT7020

Enterprise to a fire panel

1) Connect the output for fire alarm from the fire panel (CIE) to input 1 on the

2) Connect the outputs REL1, REL4 and REL5 from the Edge RT7020 to inputs

NOTE: If the Edge RT7020 is placed in its own enclosure outside of the fire

panel, then the Edge RT7020 must be powered by a source certified

according to EN54-4. For instance, directly from the fire panel.

The Edge RT7020 receives and decodes SIA at levels I, II or III, meaning

including plain text.

Edge RT7020, and output for faults from the CIE to input 2 on the Edge

RT7020. Note that if the Edge RT7020 is installed in its own enclosure,

meaning outside of the enclosure of the fire panel, then input 1 and 2 on the

Edge RT7020 must be supervised so that tamper (open and short) on the

inputs can be detected.

The inputs can be defined as supervised during programming of the unit.

To enable detection the lines are connected via two 4k7 resistors according

to the below picture.
