Security Alarm Detector Indoor Passive Infrared Motion Sensor

Reliable Dual-Tech Motion Sensor for Intruder Detection System


Passive infrared motion sensors are ubiquitous and can be found in many applications, they're also primary components for the intrusion detection system. We normally call them PIR motion sensors. It adopts dual technology which can greatly enhance the accuracy of detection. In addition to dual technology, it has a true temperature compensation design and a true digital signal processor that only triggers an alarm when all conditions are met. It is a hardwired type dual-tech motion sensor that works with different hardwired security controllers for intruder detection systems and IP video surveillance systems, as well as access control systems.

This dual-tech motion sensor for indoor occupancy/movement detection, it adopts a fresnel lens with a special coat to avoid UV/white light interference. On the back, it has a removable cover that enables installers to wire the product without disassembling the enclosure. 

ED695 includes a DIP switch that enables installers to choose different wiring methods. It has two tamper switches (front and back), normally open and normal close relay outputs, and +12V power input. This dual-tech motion sensor can work with most conventional security controllers.

ED695 includes two primary components: a microwave sensor module and a PIR sensor; the microwave sensor is also called a doppler radar or proximity sensor. The microwave sensor operates at a 10.525GHz frequency that can continuously emit microwave signals and note how these signals return to the sensor. Meanwhile, the PIR motion sensor can sense the change in infrared energy that occurs when a person or object comes into its field of view. The sensor only triggers an alarm upon which both PIR and microwave sensors are activated.

Intending to provide good flexibility, the sensitivity of the microwave sensor and PIR motion sensor is adjustable. The alarm output supports normal close and normal opening therefore it can work with different alarm controllers/panels. Additionally, this motion sensor has power input protection that prevents damage caused by incorrect wiring, and surge protection to protect the sensor from potential lightning voltage surges.

True temperature compensation design, including a temperature sensor that measures the room temperature; an illumination sensor dedicated to detecting light intensity; LED indicator on/off for discreet installation.
