Fabrikanterklæring og instruksjoner<br />

Declaration of Conformity <strong>and</strong> Instructions<br />

Konvensjonell / Conventional<br />

Anvendelse:<br />

Punkt varmedetektor for bruk i fuktige rom. Ved langsom<br />

oppvarming gir detektoren alarm ved oppnådd<br />

alarmtemperatur, 80 o C. Ved hurtig temperaturstigning<br />

kan detektoren gi alarm ved noe lavere temperatur. For<br />

bruk i eksplosjonsfarlig område, sone 1 eller sone 2.<br />

Tilkobles via zenerbarriere BZ-20. Benyttes ofte i områder<br />

der røkdetektorer ikke er egnet pga faren for falske<br />

alarmer. Detektoren har innebygget alarmindikator<br />

(LED). Detektoren kan tilkobles analoge, adresserbare<br />

system ved hjelp av adresse-/tilpasningsenhet.<br />

Prinsipp:<br />

Temperaturmåling ved hjelp av termistorføler.<br />

EEx ib-utgave for bruk i sone 1 eller<br />

sone 2<br />

Application:<br />

Heat <strong>detector</strong> for use in wet areas. The <strong>detector</strong> gives<br />

alarm when reaching a fixed alarm limit, 80 o C if the<br />

temperature increases slowly. A rapid increase in<br />

temperature may cause alarm at a slightly lower<br />

temperature. For use in hazardous areas zone 1 or zone<br />

2. To be connected via zener barrier BZ-20. Often used<br />

in areas where smoke <strong>detector</strong>s are not to be used due<br />

to the false alarm problem. The <strong>detector</strong> comprises a<br />

built-in alarm indicator (LED). The <strong>detector</strong> can be<br />

connected to an analogue, addressable system by<br />

means of interface unit.<br />

Principle:<br />

Temperature measurement by means of a thermistor.<br />
