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 from System Sensor. NFPA

Standards 72 and 90A should also be referenced for detailed

information.

NOTICE: This manual shall 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 every

area of a building. Smoke introduced into this air duct sys-

tem will be distributed to the entire building. Smoke detec-

tors designed for use in air duct systems are used to sense

the presence of smoke in the duct.

Model DH100ACDCP Air Duct Smoke Detector utilizes

photoelectric technology for the detection of smoke. This

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, 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.

The DH100ACDCP detector is designed to operate on

24 VDC/VAC, 120 VAC, or 240 VAC. Alarm and supervi-

sory relay contacts are available for control panel interface

(alarm initiation), HVAC control, and other auxiliary func-

tions. Auxiliary relays are also provided for fan shut down

or signaling of up to 9 other detectors in the loop for mul-

tiple fan shut down. These detectors are not designed for

2-wire applications.

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

test switch or by the optional remote test station. The duct

smoke detector latches into alarm state when an alarm

occurs. A green LED flashes to indicate power, a red LED

signals local alarm indication, and optional accessories

offer a variety of annunciation capabilities.

The DH100ACDCP can be reset by a momentary power

interruption, the reset button on the front cover, the control

panel, or remote reset accessory. The DH100ACDCP incor-

porates a cover tamper feature that provides a trouble

signal after 7 minutes if the cover is removed or improp-

erly installed. Proper installation of the cover removes the

trouble condition.

[2] Limitations Of Duct Smoke Detectors

WARNING

The National Fire Protection Association has established

that DUCT DETECTORS MUST NOT BE USED AS A

SUBSTITUTE FOR OPEN AREA DETECTOR PROTECTION

as a means of providing life safety. Nor are they a substi-

tute for early warning in a building’s regular fire detection

system.

System Sensor supports this position and strongly recom-

mends that the user read NFPA Standards 90A, 72, and 101.

The DH100ACDCP Air Duct Smoke Detectors are listed per

UL 268A.

WARNING

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 protec-

tion specialist.

WARNING

This device will not sense smoke unless the ventilation

system is operating and the cover is installed.

WARNING

For this detector to function properly, it MUST be installed

according to the instructions in this manual. Furthermore,

the detector MUST be protected from the elements and

operated within ALL electrical and environmental specifi-

cations listed in this manual. Failure to comply with these

requirements may prevent the detector from activating

when smoke is present in the air duct.
