Detnov DOTD-230A-I multisensor detector | optical + heat | addressable | with isolator | EN 54-5 / EN 54-7 / EN 54-17

The DOTD-230A-I is a Detnov 200A series addressable optical-heat multisensor detector for Detnov CAD-150 and CAD-250 series addressable control panels. An optical dark chamber (Tyndall effect, drift compensation, protection against dirt and insects) is combined with a heat sensor that reacts to a fast temperature rise or to a temperature above 58 °C; either sensor raises the alarm. An alarm verification algorithm reduces false alarms. The detector takes one loop address from 1 to 250; the address is set with the PGD-300 programmer or by the panel's auto-addressing. The built-in short-circuit isolator separates a shorted loop section; observe polarity when wiring. It is mounted on a Z-200 (or Z-200-H) base; the Z-200 locking option prevents unauthorised removal. LED status indicator and output for a PAD-10 remote indicator or a BUD-200 buzzer. White; certified to EN 54-5 / EN 54-7 / EN 54-17 (0370-CPR-1862).
