Security & Fire Protection Systems/fa 260 keypad


I have a FA-260 keypad. After a power outage the keypad shows no ac. How do I fix this?

There's a couple of things to check.  The first would be the circuit breaker panel.  Make sure that none of the circuits tripped when the power came on.  If those are all clear, then you should check the transformer (it's usually a small plug-in "wallwart") close to where your system's main control panel is.  Unfortunately you won't be able to see if the fuse is blown (as it's internal to the wall-wart), but you should be able to check the "AC" connection to the main panel.  You'll have to open the unit first.  Follow the wire lead from the transformer to the system board.  You'll easily be able to identify the "AC" or "power" terminal screws.  Using a volt meter, check to see if you've got 12VAC (as high as 14VAC) at the terminals.  If you're reading "zero" and the wall-wart is plugged in, you'll have confirmed that the fuse is blown.  You'll have to replace the transformer.  Please ensure you obtain one with the EXACT output characteristics stamped on the face of the unit (the part that plugs into the wall).  If you don't, you'll risk doing more damage to your system.  If you can't find one at Lowes or Home Depot, you'll have to call a "friendly" local alarm dealer and have them source one for you.  Good Luck!
