Directional PIR (EL-2650XL)

The EL‐2650XL is a wireless PIR detector that is able to distinguish between permitted and non‐
permitted motion. This allows the occupants free movement within the premises while detecting
intrusion via doors or windows. The detector implements a feature to combat the problem of
multiple transmissions, which drastically reduce the life of the batteries. After a transmission is
made, the EL‐2650XL initiates a delay of approximately three minutes during which transmissions
will not be sent. The detector operates in two selectable modes: Curtain and Directional.
