2D51 Duct Smoke Detector for Special Applications The System Sensor 2D51 low-profile photoelectric smoke detector with a B210LP base tied to the D4P120 is listed to Underwriters Laboratories 268A specifically for use in no-flow/low-flow air-handling systems. Features 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 • F ield sensitivity metering of detector to meet the requirements of 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 • C ompatible for interconnection with System Sensor InnoviarFlex™ D4120 or D4120W duct smoke detectors and remote accessories Agency Listings S911 3029700 7272-1653:203 The 2D51 can be used as a pendant mount detector in no-flow/ low-flow air-handling systems (0-4,000 FPM). The pendant /plenum mounted 2D51 is to be installed into a B210LP base and wired to a D4P120 power board-only control unit. The D4P120 power board is capable of controlling up to two 2D51 sensors. Pendant mounted in a standard electrical box within the duct, the twist-in/twist-out head allows easy removal from the base for quick cleaning and maintenance. The 2D51 heads can be locally tested using a magnet or by using the test/reset push button on the D4P120 power board. Remote testing is accomplished using the RTS151, RTS151KEY, RTS-2 or RTS-AOS accessories connected to the D4P120 power board. The APA151, RTS2 and RTS2-AOS Remote Annunciators with Piezo Alarm can also be connected to the D4P120 power board to provide an audible and visible indication of smoke detector status. 2D51 Photoelectric Detector Specifications Architectural/Engineering Specifications The air duct smoke detector shall be a System Sensor model 2D51 Series Smoke detector listed to UL 268A specifically for use in air handling systems 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 capable 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 tested using the RTS151, RTS151KEY, RTS2 or RTS2-AOS connected to the D4P120 power board. It shall be capable of providing duct smoke detector status via the UL-listed APA151, RTS2 and RTS2-AOS Piezo Annunciators.
