BEFORE INSTALLING
Read System Sensor's Applications Guide for Duct Smoke Detectors
(HVAG53), which provides information on detector spacing, placement,
zoning, wiring, and special applications. This manual is available online at
www.systemsensor.com. NFPA Standards 72 and 90A should also be refer-
enced for detailed information.

NOTE: Any combination of accessories may be used such that the given accessory
loads are: 110mA or less at the Aux output, and 50mA or less at the Alarm output.
IMPORTANT: This detector must be tested and maintained regularly following
PAGE
NFPA 72 requirements. The detector must be tested an maintained regularly fol-
lowing NFPA 72 requirements. According to NFPA, the detector should be visu-
ally inspected semiannually and functionally tested at least once a year. This
may need to be more frequent depending on the air quality of the duct supply air.
[1] LIMITATIONS OF DUCT SMOKE DETECTORS
The National Fire Protection Association has established that DUCT DETEC-
TORS MUST NOT BE USED AS A SUBSTITUTE FOR OPEN AREA DETECTOR
PROTECTION as a means of providing life safety. Nor are they a substitute for
early warning in a building's regular fire detection system.
System Sensor supports this position and strongly recommends that the user
read NFPA Standards 90A, 72, and 101. The D4120 Air Duct Smoke Detectors
are listed per UL 268A.
This device will not operate without electrical power. Fire situations may
cause an interruption of power. The system safeguards should be discussed
with your local fire protection specialist.
This device will not sense smoke unless the ventilation system is operating
and the cover is installed.
For this detector to function properly, it MUST be installed according to the in-
structions in this manual. Furthermore, the detector MUST be operated within
ALL electrical and environmental specifications listed in this manual. Failure
to comply with these requirements may prevent the detector from activating
when smoke is present in the air duct.
