Ajax Alarms liquidated stock direct from an authorised Ajax Distributor who has now retired and clearing all of the remaining Ajax Systems stock. New boxed items - No Returns - Buyer will need to be familiar with or have a going understanding of Ajax Systems to install this device. All items are sold with unique serial numbers and security marked, to protect myself from unscrupulous buyers and fraudsters, but you will see from my feedback I am an established and trusted seller, be assured these are an excellent buy and great value.
