Honeywell Home DT8035V Motion Detector

Dual-Tec technology combines two different sensing methods—Passive Infrared (PIR) and Microwave—to detect motion. By requiring both technologies to confirm movement before triggering an alarm, the sensor significantly reduces false alarms caused by environmental factors like drafts or heat sources.

This sensor features adjustable pet immunity, allowing it to ignore animals weighing up to 100 pounds (45 kg). It is designed to distinguish between human movement and pets, provided the sensor is mounted at the recommended height of 2.3 meters.

No, this device is strictly rated for indoor use only. It is designed to operate within a temperature range of -10°C to 55°C, but it is not weather-sealed for exterior environments.

The unit includes a flashlight-enabled walk test mode, which simplifies the setup process. By shining a flashlight at the sensor, you can activate the test mode to verify the detection coverage and ensure the unit is positioned to monitor your intended area effectively.

This is a hardwired device that requires a power supply between 9.0 and 15VDC. It does not use batteries, ensuring consistent, maintenance-free operation once it is connected to your security system.

The optical chamber is sealed to prevent insects from crawling inside and to block drafts from entering the sensor housing. This design choice is critical for preventing false alarms and ensuring the sensor remains reliable over time.
