The kit includes a PIR sensor and MPPL Pager and can be used to alert a carer if a user is detected leaving their bed or moving through an area in which the PIR sensor has been set up. Upon detection of movement a signal is automatically sent to the pager, which can be set to vibrate only, vibrate with a low tone or vibrate with a high tone. Up to ten sensors can be used with one pager, which can be worn on a belt clip or on a lanyard. It has an open field range of 120m. The pager and PIR sensor use 2 x AA batteries (included). Additional pagers can be linked into the kit.
