Optex HU-3 Heating Unit for SL and AX Series Detectors

The Optex HU-3 Heating Unit is a specialized accessory engineered to maintain the operational integrity of Optex SL and AX series outdoor detectors in challenging cold weather environments. By providing controlled heat, this unit effectively prevents the accumulation of frost and condensation on the detector lenses, which is critical for maintaining consistent detection accuracy and preventing false alarms caused by environmental obstructions.

Advantages

This heating unit offers a reliable solution for outdoor security systems exposed to freezing temperatures. Its primary benefit is the preservation of clear optical paths, ensuring that the infrared beams function correctly even in high-humidity or sub-zero conditions. The robust design integrates seamlessly with compatible hardware, providing a durable and long-lasting enhancement to your perimeter security setup.

Suitable for

• Outdoor security installations in cold climates
• Preventing frost buildup on detector lenses
• Maintaining sensor performance in high-humidity environments
• SL-QDM, SL-QDP, SL-QN, AX-TN, and AX-TF series detectors

This unit may not be suitable for indoor environments where temperatures remain stable and above freezing, as the heating function is unnecessary and would consume power without providing any operational benefit. It is also not compatible with detector models outside of the specified SL and AX series.

Key specifications

• Compatibility: Optex SL-QDM, SL-QDP, SL-QN, AX-TN, and AX-TF series
• Color: Black and Grey
• Quantity: 1 unit per pack
• Function: Anti-frost and anti-condensation heating

The heating unit is installed directly into the compatible detector housing. For optimal performance, it is recommended to install the units on both the transmitter and receiver components of the beam sensors. Please ensure the power supply for your security system is capable of supporting the additional load required by the heating elements.

What to consider before purchase

• Verify your specific detector model compatibility
• Calculate the total power requirements for your system
• Note that two sets are required for full coverage of SL Series beams
• Assess local climate conditions to determine if heating is necessary

For reliable operation in regions prone to heavy frost or extreme cold, ensure that the heating units are installed correctly according to the manufacturer's technical manual to maintain the IP rating and environmental seal of the detector housing.
