GENERAL
System Sensor 100 Series low-profile detectors use state-
of-the-art sensing chambers to meet all applicable UL per-
formance criteria. The backs of the smoke detectors are
sealed against back pressure, air flow, and dirt. A fine
mesh screen also protects the chamber against the entry
of insects. These detectors are intended for open area
protection and for use with UL-listed control panels.
Photoelectric/Thermal — The unique design of the
optical sensing chamber in 100 Series photoelectric smoke
detectors can sense smoke particles from a wide range of
combustion sources. These detectors minimize nuisance
alarms by using a custom integrated circuit for signal pro-
cessing.
FEATURES
• Smart-Check™ self-diagnostic maintenance feature to
satisfy NFPA 72 sensitivity testing requirements.
• Larger plug-in terminal block with captured SEMS screws
decreases wiring and installation time.
• Removable insect screen protects sensor from insects
and airborne dust.
• Includes auxiliary Form-C relay (“R” suffix).
• Built-in test switch.
• Visual alarm, power, and maintenance indicator.
• Refined insect screen for a tight seal; simplified,
removable for cleaning.
• Thermal models available.
• Ceiling white color.
• 12/24 VDC operation.
• Built-in sounder and temporal tone.
• Three-year warranty.
System Sensor 100 Series low-profile, direct-wire detec-
tors pack superb performance and reliability into a small
package. Their sleek, 1.7" (43 mm) profile is the lowest in
the industry, and the advanced circuitry provides superior
false-alarm immunity, while reducing maintenance.
Other key features include:
• Low current draw.
• Stable performance in high air velocities.
• Built-in tamper-resistant base design.
SPECIFICATIONS
• Operating voltage: 12 or 24 VDC (nominal).
• Contact rating: 1 Form-C, 1.0 A @ 30 VDC.
• Standby current: 50 µA maximum average.
• Alarm current:
2-wire models: 100 mA maximum
limited by panel. 4-wire models: 12 VDC = 35 mA
maximum; 24 VDC = 45 mA maximum ( 2112/24AITR:
60 mA maximum and 70 mA maximum respectively).
• Temperature range: 32°F to 120°F (0°C to 50°C). For
2100TD, 2112/24TR models: 32°F to 100°F (0°C to
39°C).
• Dimensions: 5.5" (140 mm) diameter. Height 1.7" (43
mm) including adapter bracket.
• Shipping weight (approximate): 5.3 oz. (150 g).
• Humidity range: 10% - 93% RH, noncondensing.
• Smoke detector spacing: On smooth ceilings (as
defined in NFPA 72), spacing of 30 feet (900 sq.ft.) may
be used as a guideline. Other spacing may be used
depending on ceiling height, high air movements, and
other conditions or response requirements. Refer to
NFPA 72 and local authority having jurisdiction.
•Air velocity: 0 to 3,000 ft./min. (914.4 m/min.) maximum.
