Mircom MIX-DH3000 Series Alpha Intelligent Duct Detectors
Description
Mircom’s MIX-DH3000 Series Intelligent Smoke Duct Detectors are the latest analog addressable innovation for early detection of smoke and products of combustion present in air moving through HVAC ducts in Commercial, Industrial, and Residential applications.
The Duct Detectors are designed to prevent the recirculation or spread of smoke by air handling systems, fans, and blowers. Complete systems may be shut down via the building’s fire alarm control panel (FACP) in the event of smoke detection.
The MIX-DH3000 Series are Low-Flow Ionization and Photoelectric air duct smoke detectors that are capable of sensing smoke in air velocities from 100 to 4,000 feet per minute (0.5 to 20.32 m/sec). Low-flow technology can detect smoke at air speed velocities of 100 feet per minute or greater, while continuing the same reliable performance to 4,000 feet per minute.
The MIX-DH3000 Series are designed and built to meet all local code requirements, as well as the NFPA and ICC standards regarding HVAC supply and return duct smoke detectors. Output terminals are provided for a remote alarm indicator accessory.

Remote Accessories
The MS-RA and MRTS-KAPR remote accessories are designed to be used with
Mircom’s Duct Smoke Detectors to provide visual indication on the detector as
well as remote test/reset functions. The MS-RA provides an LED indicator while
the MRTS-KAPR is equipped with LEDs and a test/reset switch. Enabling the
“Test” switch on the MRTS-KAPR provides a local alarm indication on the duct
detector but not at the fire alarm control panel. Both models are constructed
of attractive, durable brushed stainless steel and mount on a standard single
gang electrical backbox.
- Power Requirements: Alarm LED 15mA @ 24VDC Pilot LED 15mA @ 24VDC
- Dimensions: 4 ½” (114.3mm)H x 2 ¾”(69.85mm)W
