Before Installing

Please thoroughly read the System Sensor Guide for Proper

Use of Smoke Detectors in Duct Applications (A05-1004),

which provides detailed information on detector spacing,

placement, zoning, wiring, and special applications. Copies

of this manual are available online at www.systemsensor.

com or via System Sensor’s toll free fax-back service, Docu-

ments on Demand at 800/736-7672. NFPA Standards 72 and

90A should also be referenced for detailed information.

NOTICE: This manual should be left with the owner/user

of this equipment.

IMPORTANT: This detector must be tested and maintained

regularly following NFPA 72 requirements. The detector

should be cleaned at least once a year.

[1] General Description

An HVAC system supplies conditioned air to virtually ev-

ery area of a building. Smoke introduced into this air duct

system will be distributed to the entire building. Smoke

detectors designed for use in air duct systems are used to

sense the presence of smoke in the duct.

Model DH400ACDCP Air Duct Smoke Detector utilizes pho-

toelectric technology for the detection of smoke. This smoke

detection method, when combined with an efﬁcient hous-

ing design, samples air passing through the duct and allows

detection of a developing hazardous condition. When suf-

ﬁcient smoke is sensed, an alarm signal is initiated at the

ﬁre control panel monitoring the detector, and appropriate

action can be taken to shut off fans and blowers, change

over air handling systems, etc. These actions can facilitate

the management of toxic smoke and ﬁre gases throughout

the areas served by the duct system.

DH400ACDCP detectors are designed to operate from 24

VDC, 24 VAC, 120 VAC, or 240 VAC. Alarm and supervisory

relay contacts are available for control panel interface (alarm

initiation), HVAC control, and other auxiliary functions.

These detectors are not designed for 2-wire application.

For testing, the alarm can be enabled by a magnet activated

test switch, by insertion of a calibrated test card into the

sensing chamber (photoelectronic version only), or by the

optional remote test station. The duct smoke detectors latch

into alarm state when alarm occurs. LEDs on each detector

illuminate to provide local alarm indication, and optional

accessories offer a variety of annunciation capabilities.

The detector can be reset by a momentary power inter-

ruption, by the magnet activated reset switch, or by the

optional remote test station.
