Installation for EN54-21:2006 compliance
7.1
Introduction
The IRIS-4 4xx range of terminals are certified as compliant with the European standard EN54-21:2006 – Fire
detection and fire alarm systems - Alarm transmission and fault warning routing equipment". To comply with
this standard there are conditions to which the installation must comply. These conditions apply both to the
terminal and to the fire CIE. This guide describes these conditions.
The IRIS-4 models certified to EN54-21:2006 and for which this guide is applicable include IRIS-4 400, 420
and 440.
Note: if these conditions are not complied with, then the installation will not be compliant with EN54-
21:2006.
All other aspects of the installation are covered in the other sections of this document.
7.2
General description of the equipment
IRIS-4 4xx terminals are used to take alarms from fire CIE and transfer these reliably over IP
telecommunication networks such as broadband and cellular. The interface of the CIE uses inputs to the
terminal and outputs from the terminal.
Depending on the terminal type, backup communication over 4G/3G/2G or PSTN is also provided.
All communications paths can be constantly monitored (supervised) so any failures are reported to the ARC.
The terminals comply with both transmission system types defined in Annex A of EN54-21:2006:
Type 1: signaling path is Ethernet (e.g., broadband), cellular or Ethernet with 4G/3G/2G backup.
Type 2: one of the signaling paths is PSTN (e.g., PSTN only, cellular with PSTN backup or Ethernet with PSTN
backup).
Technical specification
Please refer to chapter 11 “Technical Specifications” for details on the appropriate 4xx terminal.

Installation, configuration, and commissioning
Monitoring requirements
The ARC should set up the monitoring reporting times (i.e., poll poll overdue period) of the site, as
follows:
For Type 1
80 seconds or less.
For Type 2
24 hours or less
Requirements for the installation
General installation instructions are in sections 4 “Basic setup” and 5 “Configuring the terminal”. The
following additional requirements are for EN54-21:2006 compliance:
The Fire CIE must be able to indicate fire signal acknowledgments and fault conditions as visual indications
driven by the outputs from the terminal, as described below. These indicators must comply with EN54-
21:2006.
