BEFORE INSTALLING

Read the System Sensor Guide for Proper Use of Smoke Detectors in Duct

Applications (HVAG53), which provides information on detector spacing,

placement, zoning, wiring, and special applications. This manual is available

online at www.systemsensor.ca. CAN/ULC S524 should also be referenced

for detailed information.

NOTICE: This manual shall be left with the owner/user of this equipment.

NOTE: The D4120A duct detector consists of D4P120A Power Board component and the D4SA Sensor component.

[1] LIMITATIONS OF DUCT SMOKE DETECTORS

WARNING

The National Fire Protection Association has established that DUCT DETEC-

TORS MUST NOT BE USED AS A SUBSTITUTE FOR OPEN AREA DE-

TECTOR 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, 101and CAN/ULC S524. The D4120A Air

Duct Smoke Detectors are listed per ULC.

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.
