The Sure Flap Microchip Pet Door is a revolutionary battery-powered pet door (cat flap) which is suitable for larger cat breeds & small dogs. It has a built in sensor which works with your pet´s existing unique identification microchip & prevents other animals from entering your home. Alternatively it can be used with an RFID collar tag. It has an LED display for easy programming. Operation of the Sure Flap Microchip Pet Door is very simple. Once the batteries have been inserted the door can be put into learn mode. It stores the microchip number of the next pet to pass through & can store up to 32 different chip numbers. Once the numbers have been saved the Sure Flap pet door will only open for those microchip numbers stray pets or other unwelcome visitors have to stay outside. The Sure Flap Microchip Pet Door has a special double lock mechanism which provides increased security against other animals. This double lock mechanism immediately locks the pet door when it recognises an intruder trying to get in. It also has a double lock on the inside which stops even the craftiest pet from opening the flap to get out. A further highlight is the Curfew Mode Programme which means that you can specify when the flap is locked & when it is open. You can also programme the door to operate in the following modes without programming any times completely open entry only exit only locked. When in the normal operation only your pet can come in but all pets can get out. If you prefer you deactivate the microchip recognition so that all pets can enter without microchip recognition. The Sure Flap pet flap is easy to install in all sorts of doors & walls. There is also an optional tunnel extension as well as a mounting adapter for installation in windows.
