<strong>Mod</strong>.<strong>1043</strong>(DS<strong>1043</strong>-078)LBT7882SMOKE AND HEAT DETECTOR<strong>Ref</strong>. <strong>1043</strong>/<strong>231</strong> – <strong>1043</strong>/<strong>232</strong>
DESCRIPTIONThe operating principle of the optical-temperaturedetectors <strong>Ref</strong>. <strong>1043</strong>/<strong>231</strong> and <strong>Ref</strong>.<strong>1043</strong>/<strong>232</strong> isbased on analysis of the spreading of light causedby the particles of smoke present in the air and ona temperature sensor with an alarm threshold at55°.The detector acts as automatic gain control; amicrocontroller calculates the compensation of thereading to maintain constant sensitivity over time,correcting any increased level due to the deposit ofdust inside the analysis cell. A red led indicates thefollowing detector conditions: during normaloperation it flashes briefly every 4 seconds; in theevent of a fault or maintenance it flashes for half asecond once a second; in the event of an alarm,the indicator glows steadily.The detector <strong>Ref</strong>.<strong>1043</strong>/<strong>232</strong> has a base with relaywith NC and NO contacts for activating externaldevices in the event of an alarm..ASSEMBLY AND INSTALLATIONINSTRUCTIONSInstall the ceiling detector using 2 bolts.The detector is connected to the base making thereference arrows coincide.After installation and before testing, remove thedust cover from the detector.<strong>Ref</strong>erencearrowTRADIZIONALEALIM.
