System Sensor 2D51

2D51 Duct Smoke for Applications System Sensor 2D51 low profile photoelectric smoke with a B210LP base tied to the D4P120 is listed Underwriters Laboratories 268A specifically for use in air handling systems for 2D51 B210LP D4P120 Low profile smoke detector design Low standby current Two LEDs blink in standby Detector head plugs easily into base Built in test switch Field sensitivity metering of detector to meet the requirements NFPA 72 with the use of RTS2 RTS2 AOS and SENS RDR Designed for mounting on a standard electrical box SEMS screws for easy wiring and positive wire retention Removable cover and insect screen for field cleaning Remote push button Test Reset LEDs provide visual indications Onboard supervisory and alarm relays Accepts 24 or 120V supply voltage Interconnect up to 100 units for common functions Compatible for interconnection with System Sensor InnoviarFlex or D4120W duct smoke detectors and remote accessories 2D51 can be used as a pendant mount detector in no flow air handling systems 0 4,000 FPM The pendant plenum 2D51 is to be installed into a B210LP base and wired to a power board only control unit The D4P120 power board is of controlling up to two 2D51 sensors mounted in a standard electrical box within the duct the head allows easy removal from the base for quick and maintenance The 2D51 heads can be locally tested a magnet or by using the test reset push button on the D4P120 board testing is accomplished using the RTS151 RTS151KEY or RTS AOS accessories connected to the D4P120 power APA151 RTS2 and RTS2 AOS Remote Annunciators with Piezo can also be connected to the D4P120 power board to provide audible and visible indication of smoke detector status Listings Photoelectric Detector Specifications Specifications air duct smoke detector shall be a System Sensor model 2D51 Series Smoke detector listed to UL 268A specifically for use in air handling when used in conjunction with the B210LP base The detector shall operate at air velocities up to 4,000 feet per minute It shall be of local testing using a magnet test on the 2D51 or using a test reset button on the D4P120 power board It can also be remotely using the RTS151 RTS151KEY RTS2 or RTS2 AOS connected to the D4P120 power board It shall be capable of providing duct detector status via the UL listed APA151 RTS2 and RTS2 AOS Piezo Annunciators Specifications
