Our Sensomat wireless kits are for use when caring for elderly or loved ones with dementia in their own home. The Sensotrol Wireless (SW3) units contained in these kits replicate a nurse call bell system. The wireless unit consists of two parts, a transitter and receiver. Our Sensomat pads, mats or PIR sensors can be plugged into the Sensotrol wireless transmitter. When the mat is activated a signal is transmitted to the caregiver's Sensotrol receiver unit. This will sound a bell and alert them that their family member needs attention. Some kits also contain a pushbutton call bell (pendant) for their family members use if so desired. Most of the kits are battery operated and don't need to plug into a power point. Batteries are included. Easy to purchase, simply add products to the shopping cart and payment can be made with your credit or debit card by Paypal or you can pay by internet banking.
