Watertight
4-Wire Low-Flow
Duct Smoke Detector
The System Sensor DH100ACDCLWP Watertight
Innovair™ is a NEMA 4 duct smoke detector rated for
installation and use in non-hazardous indoor and
outdoor applications.
Features
The DH100ACDCLWP is UL listed as a watertight enclosure providing
protection against falling dirt, rain, windblown dust, splashing and
hose directed water. Additionally, this detector features advanced
Low-Flow technology, capable of sensing smoke in air velocities from
100 to 4,000 feet-per-minute (0.5 to 20.3 meters-per-second).
• NEMA Type 4 UL listed for non-hazardous indoor and outdoor
applications
• Air velocity rating from 100 to 4000 feet-per-minute
(0.5 to 20.32 m/sec.)
• Patented interconnectability for multi-fan shutdown
(up to 10 air handlers)
The DH100ACDCLWP can be directly mounted to rooftop HVAC
equipment or used in other environmentally harsh applications that
fall within its specified temperature limits. Since the unit is NEMA
4 rated, no additional enclosure is needed. The Watertight Innovair
provides the same form, fit and wiring terminations as the standard
Innovair but meets the NEMA 4 requirements, providing unsurpassed
environmental protection.
• Patented telescopic sampling tube
• Patented cover tamper trouble signal
• 24 VAC/DC or 120/240 VAC operation
• High-Low voltage barrier
• Equipped with two DPDT Form C relay contacts
• Built-in reset button
In addition to being the only watertight duct smoke detector on the
market, the revolutionary Innovair solves many difficult low airflow
duct applications where reliable smoke detection is critical. Innovair
with Low-Flow technology can detect smoke in air speed velocities
as low as 100 feet-per-minute or as high as 4,000 feet-per-minute.
• Outside mounting tabs
• Easy and quick mounting to round or rectangular ducts from
1´–12´ (0.3–3.7 meters) wide
• Easy to clean
The Innovair family is designed for simplified installation and easy
maintenance. The modular construction allows for easy cleaning and
simple field replacement of the UL-recognized power and sensor
boards. System Sensor has again set the standard for HVAC smoke
detection technology.
• UL recognized field-replaceable power and sensor boards
• Remote test station option
• Remote sounder option
• UL 268A listed
WARNING: Duct smoke detectors have specific limitations.
