PIR-2712 is a general purpose PIR sensor. It is designed to give a cost effective and reliable solution for the residential and commercial security systems. PIR-2712 employs a low noise dual-element pyro-sensor and an MCU device in security logic and environmental controls.

The alternate polarity signal processor inside the MCU has very high rejection to noise dur to radio interference or power surges. The MCU device also provides the functions of digital pulse counting, power-up delay and alarm output timing and controls. All of which maximises security and false alarm immunity.

Features:

• Low noise dual element pyro-sensor
• Alternate polarity signal processing
• Security logics are integrated in the MCU device
• Surface-mount component technology, great EMI and RFI immunity
• Normal or pulse count response for harsh environments
• NC or NO contact for alarm output
