The detector provides simultaneous control of the specific optical air density level in the space above suspended ceilings and inside the room. Unique feature - you use the single unit instead of two Easy to install & Twice-Cut: cutting installation and removement time and making maintenance easy Yellow and red LEDs indicate 7 various conditions of both sensors: standby mode, Fire status of upper sensor, Fire status of lower sensor, Fire status of both sensors, Fault status of upper sensor, Fault status of lower sensor, Fault status of both sensors. Easy monitoring of upper sensor that is unique relatively to the traditional way of protection of premises with suspended ceilings Automatic drift compensation Self diagnostic feature detecting faults Mechanical testing Mounting base and protective cap included Length options for the rod connecting sensors (*0, *0, *0 cm) Mounting ring should be used to install the detector onto suspended ceiling Dimensions Ø**0x**0 mm Weight **0 g SP*2.1 *-wire connection One red and one yellow LED indicators Supply voltage range ****0V SP*2.2 *-wire connection One red and one yellow LED indicators Supply voltage range ****5 V SP*2.4 Two *-wire lines connection Two red and one yellow LEDs indicating critical level of contamination for upper and lower sensors besides regular statuses Supply voltage range ****0V
