This remote control works exclusively with our MA795DC (10-7410). This IR remote control will only work with the MA795DC only. The extra remote control will allow an additional user to arm and disarm the alarm as long as the dip switches (programmable codes) are set the same on the remote and alarm. With the included key ring you always will know where the remote is located. The remote requires a 12 volt battery that is included. Dimensions are 2 1/2 inches x 1 inches x 1/2 inches not including the key ring.
