How to change the battery of security system made by Westinghouse security system, model EN155OR?

I am unfamilar with that model but it should be the same as any other system.



In the panel box (usually located in a basement/near your home's breakers) the battery sits just in the bottom. Remove the positivie %26amp; negative leads from the old battery, and connect them to the new battery... black to black, red to red. Very simple. :)How to change the battery of security system made by Westinghouse security system, model EN155OR?
