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
• Field 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
• Compatible for interconnection with System Sensor InnoviarFlex™
D4120 or D4120W duct smoke detectors and remote accessories
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.
