1IASBOX - TECHNICAL MANUAL

FOREWORD

FOR THE INSTALLER:

Please follow carefully the specifications relative to electric and security systems realization further to the manufactu-

rer’s prescriptions indicated in the manual provided.

Provide the user the necessary indication for use and system’s limitations, specifying that there exist precise specifi-

cations and different safety performances levels that should be proportioned to the user needs. Have the user view

the directions indicated in this document.

FOR THE USER:

Periodically check carefully the system functionality making sure all enabling and disabling operations were made cor-

rectly.

Have skilled personnel make the periodic system’s maintenance. Contact the installer to verify correct system opera-

tion in case its conditions have changed (e.g.: variations in the areas to protect due to extension, change of the access

modes, etc…)

......................................................

This device has been projected, assembled and tested with the maximum care, adopting control procedures in accor-

dance with the laws in force. The full correspondence to the functional characteristics is given exclusively when it is

used for the purpose it was projected for, which is as follows:

1 Input Analogue Addressable Module

Any use other than the one mentioned above has not been forecasted and therefore it is not possible to guarantee its

correct operativeness.

The manufacturing process is carefully controlled in order to prevent defaults and bad functioning. Nevertheless, an

extremely low percentage of the components used is subjected to faults just as any other electronic or mechanic pro-

duct. As this item is meant to protect both property and people, we invite the user to proportion the level of protection

that the system offers to the actual risk (also taking into account the possibility that the system was operated in a de-

graded manner because of faults and the like), as well reminding that there are precise laws for the design and as-

semblage of the systems destinated to these kind of applications.

The system’s operator is hereby advised to see regularly to the periodic maintenance of the system, at least

in accordance with the provisions of current legislation, as well as to carry out checks on the correct running

of said system on as regular a basis as the risk involved requires, with particular reference to the control unit,

sensors, sounders, dialler(s) and any other device connected. The user must let the installer know how well

the system seems to be operating, based on the results of periodic checks, without delay.

Design, installation and servicing of systems which include this product, should be made by skilled staff with the ne-

cessary knowledge to operate in safe conditions in order to prevent accidents. These systems’ installation must be

made in accordance with the laws in force. Some equipment’s inner parts are connected to electric main and therefore

electrocution may occur if servicing was made before switching off the main and emergency power. Some products

incorporate rechargeable or non rechargeable batteries as emergency power supply. Their wrong connection may da-

mage the product, properties and the operator’s safety (burst and fire).

TECHNICAL MANUAL - 1IASBOX

1. GENERAL

1IASBOX module has been designed for advanced fire detection systems managed by FX/50, FX/20 and FX/10

control panels (and other compatible) equipped with loop operating with AS protocol; it is equipped with 1 balanced/

non-balanced programmable input.

The module can be connected to devices or traditional fire detectors with NO relay output contacts (free from po-

tential).

The digital transmission of the alarm event is triggered when the module receives an alarm, that is, when the de-

tector contact closes. The alarm condition is kept until the contacts go back to NO status. When the contact closes,

a 18KOhm resistance will be connected in parallel to the 47KOhm line balancing resistance; open line or short-cir-

cuited status will be detected as fault condition by the module. The alarm condition can be signalled next to the de-

tector by connecting a low-consumption LED diode (as specified below) to the terminal output. Module input can be

set to "non-balanced" by using the dipswitch no. 1 (OFF). In this case, the end-of-line resistor is not required and the

detector contact has to be directly wired to the terminals. When the detector contact closes, the module will receive

the alarm event, but it will no longer be able to detect (and signal) the fault event (but only alarm event).

1IASBOX is equipped with a two-colour LED to indicate: input fault condition (blinking red), alarm status (steady

red), and interrogation status (blinking green, the unit interrogates the module). Use dipswitch no. 2 (OFF) to disable

input fault conditions and alarm status signalling (red light).

1IASBOX module communicates with the fire panel over serial loop and in case of correct communication, the

two-colour LED will blink green. The loop is connected to the AS protocol via SIG and -S terminals. This connection

does not require an external power supply unit.

1IASBOX module is supplied with a reduced-dimension plastic housing and is also suitable to be installed on 503-

type flush-mount boxes.

6. ID ADDRESS SETUP

The setup procedure of 1IASBOX module ID address is very easy: it is equipped with three rotary dip

switches corresponding, respectively, to hundreds (x100), tens (x10), and units (x1) of the code to set.

Please consider that code setup is fundamental for the correct identification of the module from the control

panel; the module will be detected as one input module.

Example:

1IASBOX module with ID code 035:

IMPORTANT: do not use the ID addresses 0 (zero) and 255.
