Intelligent Air Duct Detectors
The Advanced Intelligent Air Duct Detectors are the latest
innovation for early detection of smoke and products of
combustion present in air moving through HVAC ducts in
Commercial, Industrial, and Residential applications. The units are
designed to prevent the recirculation or spread of smoke by air
handling systems, fans, and blowers. Complete systems may be
shut down in the event of smoke detection.
The operating principle of the Intelligent Air Duct Detectors is
based on the Venturi effect. Two tubes extend into the HVAC duct.
Air flowing through the duct is forced into the air intake (inlet) tube
via the air intake holes (facing the air flow) and passes over the
detector head. The air will be drawn out via the exhaust tube back
into the HVAC duct. When the concentration of smoke particles
suspended in the air stream reach the alarm threshold of the
intelligent detector head the Intelligent Air Duct Detector will go
into alarm thus alarming the Axis AX Series Intelligent Fire Alarm
Control Panel.
The Intelligent Air Duct Detectors are designed to operate in duct Features
widths from 6” to 10’ wide with an air velocity between 100 to
4,000 feet per minute. 2/4 Wire with Intelligent Photo or Ion Detector
Low-Flow Technology (100-4000ft/min)
Four (4) versions of the Intelligent Air Duct Detector are available
from Advanced, the versions include both two and four wire Listed for High-Temp Applications
operation with an intelligent photoelectric or ionization detector. Patented “No-Tools Required”
Two wire versions do not include an alarm relay contact, and can
only drive a remote LED indicator. If alarm relay contact and/or Patented “Test Port Valve”
additional remote accessory options are required, beyond a Instantaneous Cover Removal Indication
remote LED, the four wire version must be provided.
Staggered Terminal Blocks for Easier Wiring
The Intelligent Air Duct Detectors are built to meet all local code Flashing Detector LED Indicating Normal Operation
requirements, as well as the NFPA and ICC standards regarding
HVAC supply and return duct smoke detectors. Output terminals
are provided for a wide range of remote accessories such as Listings and Approvals
remote status indicators, and test/reset key switches or push
buttons. The Intelligent Air Duct Detectors include many features ETL ANSI/UL 864 Listed: 101564744NYM-001
that represent true innovations from current generation duct smoke UL File: UROX.S2829
